웹 프론트엔드 프레임워크, 무엇을 쓸까?

웹 프론트엔드 프레임워크, 무엇을 쓸까?

www.samsungsds.com

과거와 달리 최근에는 자바스트립트 진영에서도 프레임워크를 이용한 개발이 필수로 여겨지고 있습니다. 2017년까지만 해도 개발자들은 프로젝트에 Angular와 React 중 어느 것을 사용해야 하는지 여부를 주로 토론했으나, 2018년 이후 Vue.js라는 새로운 프레임워크에 대한 관심이 높아지고 있는 추세입니다. 본 아티클에서는 웹 프론트엔드 영역에서 주요 라이브러리와 프레임워크로 자리잡은 React와 Vue.js, Angular의 현재 상태와 향후 전망을 살펴보겠습니다.

Angular
강력한 명령행 도구와 잘 정돈된 폴더 구조, 프로젝트 생성과 동시에 각종 환경이 한 번에 갖춰지는 등 필요한 기능을 모두 내장한 프레임워크입니다. 참고로 이렇게 애플리케이션을 만들기 위해 필요한 기능을 모두 갖춘 프레임워크를 '컴플리트 프레임워크(Complete Framework)'라고 합니다.
Google이 개발한 Angular는 2010년에 처음 출시되어 가장 오래 되었습니다. 2016년에는 타입스크립트(TypeScript) 기반 프레임워크인 Angular 2가 출시되면서 실질적인 전환이 이루어졌습니다.(AngularJS라는 원래 이름에서 'JS'가 삭제됨) AngularJS(버전 1)는 여전히 업데이트를 제공하고 있지만, 본 아티클은 Angular에 대한 토론을 집중적으로 다룹니다. 최신 안정버전은 2018년 10월에 출시된 Angular 7입니다.

React
사용자의 조작에 따라 사용자 인터페이스가 동적으로 변화하는 웹 애플리케이션을 개발할 수 있게 해 주는 프론트엔드 라이브러리입니다. React는 "A JavaScript library for building user interfaces"라고 주장하며 라이브러리를 표방하고 있습니다. Facebook이 개발한 React는 2013년에 출시되었으며, Facebook은 React를 자사의 제품(Facebook, Instagram 및 WhatsApp)에서 광범위하게 사용합니다. 2018년 11월에 발표된 16.x가 최신 안정버전입니다.

Vue.js
Vue.js는 이 그룹에서 가장 늦게 출시되었는데 Google 직원인 Evan You가 2014년에 개발했습니다. Vue.js는 대기업의 후원을 받지 못했음에도 지난 2년 동안 인기가 높아지고 있습니다. 현재 안정버전은 2.17이며, 2018년 8월에 출시되었습니다. Vue.js의 컨트리뷰터는 Patreon에서 지원하며, 현재 프로토타입 단계에 있는 Vue3은 타입스크립트 기반으로 이동할 계획입니다.

 

특징

Angular
프레임워크라는 것입니다. 최근에는 자바스크립트로 웹페이지뿐만 아니라, 스마트폰이나 데스크탑에서 동작하는 애플리케이션을 개발할 수 있는데, Angular는 이를 지원하기 위한 기능들을 갖추고 있습니다.
또한, 타입스크립트를 주력언어로 채택하여 정적 타입을 제공하고 있습니다. 정적 타입의 도입으로 코드 어시스트, 타입 체크, 리팩토링을 지원하는 강력한 도구 사용이 가능해지며, 객체지향적 프로그래밍에 적합해집니다. 이는 많은 개발자 간의 협업이 필요한 대규모 애플리케이션 개발에 보다 효과적입니다.

Angular가 제공하는 또 다른 강력한 도구는 Angular CLI입니다. 프레임워크에 익숙하지 않은 초심자들이 가장 어렵게 생각하는 장벽 중 하나인 개발환경 구축을 Angular CLI가 제공하는 명령 하나만으로 간단히 해결할 수 있습니다. 아울러 다른 프레임워크가 제공하는 CLI와는 달리 추가적인 명령들을 통해 개발환경 구축뿐만 아니라, 개발 전반에 걸쳐 편리함을 제공합니다.

그리고 Angular는 컴플리트 프레임워크에 걸맞게 Router, Forms, HTTP 등 다양한 모듈을 지원합니다. 또한 RxJS를 내장하고 있어 HTTP 뿐만 아니라 모든 이벤트를 스트림으로 RxJS의 옵저버 패턴에 의해 유연하게 제어할 수 있습니다. 그 밖에도 애니메이션을 위한 Angular Animations, 국제화를 위한 i18n 모듈, 테스팅 모듈 등도 제공하고 있습니다.

또 다른 특징으로 컴포넌트 기반 개발을 중심으로 한다는 점을 들 수 있습니다. 컴포넌트 기반으로 개발한다는 것은 컴포넌트의 형태로 사용자 인터페이스를 정의하고, 자바스크립트 파일뿐 아니라 템플릿 역할을 할 HTML 파일이나 스타일시트가 담긴 CSS 파일도 컴포넌트에 포함한다는 것입니다. 이 파일들은 컴포넌트마다 자동으로 생성됩니다.

또한 Angular는 타입스크립트의 문법인 'decorator'를 많이 활용하는 선언적 코딩 스타일을 사용합니다. 태그명, 템플릿 파일, CSS 파일에 대한 정보를 decorator 문법으로 전달하고 있습니다.


React
React의 특징은 Angular와 달리 개발에 필요한 모듈을 기본으로 제공하지 않고, 서드파티(Third party) 라이브러리에 의존한다는 점입니다. 공식적으로 React는 작은 자바스크립트 UI 라이브러리일 뿐, 그 외의 것은 사용자에게 일임하고 있습니다. 대신 다른 프레임워크에 비해 방대한 에코시스템이 존재합니다. 사용자는 자유롭게 개발에 필요한 모듈을 결정하고 선택할 수 있습니다. 커다란 에코시스템은 React의 장점으로 보이지만 사용자에게 책임이라는 부담을 지우기도 합니다. 그러나 다행스럽게도 React 진영이 이러한 사용자 부담에 대해 완전히 손놓고 있지는 않습니다. Angular CLI와 마찬가지로 초심자의 빠른 개발환경 구축을 위해서 Create React App이라는 툴을 제공하여 진입 장벽을 낮추고 있습니다.

React 역시 컴포넌트 기반의 개발을 채택하고 있습니다. 그러나 컴포넌트의 구현은 자바스크립트에 조금 더 치중되어 있습니다. 다른 프레임워크들이 HTML 마크업 기반으로 그 위에 템플릿 문법을 추가해 컴포넌트의 구조와 구성요소를 정의하는 반면, React는 XML 포맷의 템플릿을 직접 자바스크립트에 내장시키는 형태로 JSX 기술을 주력으로 사용하는 것을 권장하고 있습니다. 그렇기 때문에 다른 프레임워크에 비하여 더 자바스크립트에 집중된 형태의 컴포넌트가 나타나게 됩니다.

React가 Angular와 구별되는 또 다른 특징 중 하나는 가상 DOM을 이용한다는 것입니다. 가상 DOM은 가상 트리 형태의 자료구조에 실제 DOM 트리가 매핑된 형태로 동작합니다. 전통적인 DOM은 한 요소에서 변경이 발생하더라도 전체 트리구조를 업데이트하기도 합니다. 따라서 렌더링 성능이 떨어질 수 있는 불안요소가 있습니다. 가상 DOM은 가상 DOM 내의 변경사항을 추적하여 전체 트리의 다른 부분에 영향을 주지 않고, 매핑된 실제 DOM상의 특정요소만 업데이트할 수 있게 도와 줍니다. 일반적으로 가상 DOM이 실제 DOM을 조작하는 것에 비해 성능이 뛰어나다고 볼 수 있습니다. 하지만 Angular는 실제 DOM 위에서 동작함에도 변경감지 구현 기능이 따로 존재하여 성능을 높이고 있다는 것을 참고하시기 바랍니다.

React만의 특징이 한 가지 더 있습니다. 바로 데이터 바인딩 방법입니다. 데이터 바인딩은 모델(비즈니스 로직)과 뷰(UI) 간에 데이터를 동기화하는 프로세스입니다. 기본적으로 단방향과 양방향이라는 두 가지 구현방식이 있습니다. 두 방법의 차이는 모델-뷰(Model-View) 업데이트 처리 방식입니다. 양방향 데이터 바인딩은 뷰가 변경되면 모델도 변경되며 모델이 변경되면 뷰도 변경되는 처리방식입니다. React는 단방향 데이터 바인딩을 사용합니다. 모델이 변경되면 뷰가 변경되는 방법만을 허용하고, 뷰가 변경된 경우 모델을 변경시키지 않습니다. 뷰가 변경된 경우 모델을 변경하는 코드를 작성해야 합니다. 단방향 데이터 바인딩은 일반적으로 예측 가능성이 높기 때문에 코드가 더 안정적이지만, 양방향 바인딩에 비해서 코드 작성시간이 더 필요합니다. 참고로 Angular와 Vue.js는 단방향 데이터 바인딩과 양방향 데이터 바인딩 모두 지원합니다.


Vue.js
Vue.js도 React처럼 가상 DOM을 사용하고, 컴포넌트 기반 개발을 중심으로 합니다. 그러나 React와 구별되는 Vue.js만의 특징은 컴포넌트의 자바스크립트 집중도가 낮다는 점입니다. 즉 JSX를 권장하는 React와는 달리, 컴포넌트 구조와 구성요소를 작성할 때 Angular처럼 HTML 마크업 기반의 템플릿 문법을 사용합니다. Vue.js 컴포넌트 작성 시 보통 '단일 파일 컴포넌트'라는 .vue 확장자를 가지는 파일을 사용합니다. 이 파일은 HTML 마크업 기반의 템플릿 부분과 자바스크립트 부분 그리고 CSS를 작성하는 스타일 시트 부분으로 나뉩니다. React에 비해 기존 HTML, CSS에만 익숙한 웹 디자이너가 Vue.js를 접했을 때 컴포넌트 구성요소와 구조를 쉽게 이해할 수 있습니다. 따라서 React보다 기존 웹 디자이너와의 협업이 쉬워지는 장점이 있습니다.

다른 프레임워크들과 마찬가지로 Vue.js도 CLI 툴을 제공합니다. 그리고 애플리케이션 개발에 필요한 다른 모듈을 React처럼 사용자에게 책임을 맡기지 않고 가이드 문서를 통해 특정모듈을 권장하고 있습니다. Angular처럼 내장모듈로 정해진 것은 아니지만 React처럼 방임에 가깝게 두지도 않고 둘 사이를 절충한다고 볼 수 있습니다.

주목할 만한 것은 대기업 직원이 주도하고 있는 다른 프레임워크들과 달리 Vue.js는 커뮤니티가 주도하는 프레임워크라는 것입니다. 문서나 코드의 품질이 떨어질까 우려될 수도 있으나, 다행스럽게도 공식문서가 여러 나라의 언어로 잘 번역되어 있을 뿐만 아니라, 문서의 구성이 예제 위주로 되어 있어 필요한 내용만 빠르게 발췌하여 적용할 수 있습니다. 이는 진입장벽을 낮춰주는 또 다른 장점으로, React에 비해 초심자에게 비교적 접근성이 뛰어나다고 볼 수 있습니다.

크기 및 로드타임

각 프레임워크의 크기는 다음과 같습니다.

Angular : 500KB
React : 100KB
Vue.js : 80KB

프레임워크 간의 크기는 상당한 차이가 있지만 평균 웹 페이지 크기와 비교할 때는 모두 작다고 볼 수 있습니다. 또한 자주 사용하는 CDN을 사용하여 이러한 라이브러리를 로드하는 경우 이미 사용자의 로컬시스템에 라이브러리가 로드되어 있을 가능성이 높습니다.

 

컴포넌트

컴포넌트는 Vue.js, React, Angular 세 가지 프레임워크의 핵심적인 부분입니다. 컴포넌트는 일반적으로 입력을 받아 이를 기반으로 동작을 수행합니다. 동작 수행은 통상 페이지 전체나 일부 UI 변경으로 나타납니다. 컴포넌트를 사용하면 쉽게 코드를 재사용할 수 있습니다. 컴포넌트는 페이지 전체 혹은 일부일 수 있습니다. 페이지 전체가 컴포넌트의 트리 형태로 나타날 수 있습니다. 하나의 페이지에서 일부 컴포넌트를 가져다가 다른 페이지에서 재사용할 수도 있습니다.

Angular에서는 컴포넌트는 Directive를 이용합니다. Directive는 DOM 요소에 대한 어떠한 표시이고, Angular는 이를 통해 특정 동작을 위한 DOM을 추적하거나 DOM에 동작을 첨부할 수 있습니다. 따라서 Angular는 컴포넌트의 UI 부분을 HTML 태그와 속성으로 따로 두고, 자바스크립트 코드를 UI의 동작을 위해 따로 둡니다.
흥미롭게도 React는 UI 표현과 동작을 결합합니다. 이전에 말했다시피 React에서는 JSX 기술을 통해 자바스크립트의 코드 위주로 UI를 표현하고 그 동작을 지시합니다.
Vue.js에서는 UI 표현과 동작이 모두 컴포넌트 파일의 일부이기 때문에 React와 비교할 때 더 직관적으로 작업할 수 있습니다. 또한 Vue.js는 자바스트립트 내에서도 UI의 구성요소와 동작을 결합할 수 있습니다.

학습 난이도

Angular는 완전한 솔루션이라고 생각해 높은 학습 난이도를 가지고 있으며, 이를 마스터하려면 타입스크립트 및 MVC와 같은 관련 개념을 배워야만 합니다. Angular를 배우는 데는 시간이 걸리지만 이같은 시간 투자는 프론트엔드 전체의 동작방식을 이해하는 측면에서 개발자에게 도움이 되기도 합니다.

React는 약 1시간만에 사용환경을 설정할 수 있는 Getting Started 가이드를 제공합니다. 문서는 철저하고 완벽하며, 일반적인 문제에 대한 해답은 StackOverflow에 등록되어 있습니다. React는 완전한 프레임워크가 아니기 때문에 고급기능을 위해서는 서드파티 라이브러리를 사용해야 합니다. 이로 인해 핵심 프레임워크의 학습난이도가 높지는 않지만 추가기능으로 수행하는 경로에 따라 달라집니다. 또한 서드파티 라이브러리를 사용하는 것이 반드시 모범사례인 것만은 아닙니다.

Vue.js는 Angular나 React보다 배우기가 더 쉽습니다. 또한 Vue.js는 컴포넌트 사용과 같은 기능에 대해 Angular 및 React와 많은 부분이 겹칩니다. 따라서 두 가지 중 하나에서 Vue.js로의 전환은 비교적 용이한 편입니다. 그러나 Vue.js의 단순성과 유연성은 양날의 검입니다. 디버깅 및 테스트가 어려워질 수도 있기 때문입니다.

Angular, React 및 Vue.js는 비교적 서로 다른 학습난이도를 가지고 있지만 학습범위는 매우 넓습니다. 예를 들어, Angular와 React를 WordPress 및 WooCommerce와 통합하여 점진적인 웹 앱을 만들 수 있습니다.

과거 1년 동안 React와 Vue.js, Angular의 NPM(Node Package Manager) 다운로드 현황으로 추측해 보건대, 당분간은 React가 계속해서 대세로 자리잡을 것으로 보입니다.

10.0.0-next.7 (2020-05-13)

Bug Fixes

Features

  • compiler: add name spans for property reads and method calls (#36826) (eb34aa5)
  • language-service: [ivy] wrap ngtsc to handle typecheck files (#36930) (1142c37)
  • core make generic mandatory for ModuleWithProviders (#36892) (20cc3ab)

BREAKING CHANGES

  • core: make generic mandatory for ModuleWithProviders

A generic type parameter has always been required for the ModuleWithProviders pattern to work with Ivy, but prior to this commit, View Engine allowed the generic type to be omitted (though support was officially deprecated). If you're using ModuleWithProviders without a generic type in your application code, a v10 migration will update your code for you.

However, if you are using View Engine and also depending on a library that omits the generic type, you will now get a build time error similar to:

error TS2314: Generic type 'ModuleWithProviders<T>' requires 1 type argument(s).

In this case, ngcc won't help you (because it's Ivy-only) and the migration only covers application code. You should contact the library author to fix their library to provide a type parameter when they use this class.

As a workaround, we suggest setting skipLibChecks to false in your tsconfig or updating your app to use Ivy.

  • compiler-cli: perform template type-checking incrementally (#36211) (ecffc35)
  • compiler-cli: split Ivy template type-checking into multiple files (#36211) (b861e9c)

BREAKING CHANGES

  • TypeScript versions 3.6 and 3.7 are no longer supported, please update to TypeScript 3.8

  • forms: Number inputs no longer listen to the change event.

Tests which trigger change events need to be updated to trigger input events instead.

The change event was in place to support IE9, as we found that input events were not fired with backspace or cut actions. If you need to maintain IE9 support, you will need to add a change event listener to number inputs and call the onChange method of NumberValueAccessor manually.

Lastly, old versions of WebDriver would synthetically trigger the change event on WebElement.clear and WebElement.sendKeys. If you are using an old version of WebDriver, you may need to update tests to ensure input events are triggered. For example, you could use element.sendKeys(Keys.chord(Keys.CONTROL, "a"), Keys.BACK_SPACE); in place of element.clear().

  • forms: The minLength and maxLength validators now verify that the form control's value has a numeric length property, and only validate for length if that's the case.

Previously, falsey values without the length property (such as 0 or false values) were triggering validation errors. If your code relies on the old behavior, you can include other validators such as min or requiredTrue to the list of validators for a particular field.

  • bazel: esm5 and fesm5 format is no longer distributed in Angular's npm packages e.g. @angular/core

If you are not using Angular CLI to build your application or library, and you need to be able to build es5 artifacts, then you will need to downlevel the distributed Angular code to es5 on your own.

Angular CLI will automatically downlevel the code to es5 if differential loading is enabled in the Angular project, so no action is required from Angular CLI users.

  • ngcc: speed up the getBasePaths() computation (#36881) (e037840)

BREAKING CHANGES

  • core: Warnings about unknown elements are now logged as errors. This won't break your app, but it may trip up tools that expect nothing to be logged via console.error.
  • router: Any resolver which return EMPTY will cancel navigation. If you want to allow the navigation to continue, you will need to update the resolvers to emit some value, (i.e. defaultIfEmpty(...), of(...), etc).
  • service-worker: Previously, Vary headers would be taken into account when retrieving resources from the cache, completely preventing the retrieval of cached assets (due to ServiceWorker implementation details) and leading to unpredictable behavior due to inconsistent/buggy implementations in different browsers.

Now, Vary headers are ignored when retrieving resources from the ServiceWorker caches, which can result in resources being retrieved even when their headers are different. If your application needs to differentiate its responses based on request headers, please make sure the Angular ServiceWorker is configured to avoid caching the affected resources.

  • common: This change could result in ExpressionChangedAfterItHasBeenChecked errors that were not detected before. The error could previously have gone undetected because two WrappedValues are considered "equal" in all cases for the purposes of the check, even if their respective unwrapped values are not.

Additionally, [val]=(observable | async).someProperty will no longer trigger change detection if the value of someProperty is identical to the value in the previous emit. If you need to force change detection, either update the binding to use an object whose reference changes or subscribe to the observable and call markForCheck as needed.

10.0.0-next.3 (2020-04-22)

Bug Fixes

BREAKING CHANGES

  • common: format day-periods that cross midnight

    When formatting a time with the b or B format codes, the rendered string was not correctly handling day periods that spanned midnight. Instead the logic was falling back to the default case of AM.

    Now the logic has been updated so that it matches times that are within a day period that spans midnight, so it will now render the correct output, such as at night in the case of English.

    Applications that are using either formatDate() or DatePipe and any of the b or B format codes will be affected by this change.

BREAKING CHANGES

  • i18n: The CLDR data has been updated to v36.0.0, which may cause some localized data strings to change. For example, the space separator used in numbers in the fr locales changed from \xa0 to \u202f (c1bd3bc)
  • bazel: @angular/bazel ng_setup_workspace() is no longer needed and has been removed. We assume you will fetch rules_nodejs in your WORKSPACE file, and no other dependencies remain here. Simply remove any calls to this function and the corresponding load statement.
  • typescript 3.4 and 3.5 are no longer supported, please update to typescript 3.6
  • We no longer directly have a direct depedency on tslib. Instead it is now listed a peerDependency.

Users not using the CLI will need to manually install tslib via;

yarn add tslib

or

npm install tslib --save

  • forms: * <ngForm></ngForm> can no longer be used as a selector. Use <ng-form></ng-form> instead.
  • The NgFormSelectorWarning directive has been removed.
  • FormsModule.withConfig has been removed. Use the FormsModule directly.
  • core: The deprecated type Renderer has been removed. Use Renderer2 instead.
  • core: The deprecated type RenderComponentType has been removed. Use RendererType2 instead.
  • core: The deprecated type RootRenderer has been removed. Use RendererFactory2 instead.
  • service-worker: Remove deprecated option versionedFiles from service worker asset group configuration in ngsw-config.json

Before

"assetGroups": [ { "name": "test", "resources": { "versionedFiles": [ "/**/*.txt" ] } } ]

After

"assetGroups": [ { "name": "test", "resources": { "files": [ "/**/*.txt" ] } } ]

  • ivy: Translations (loaded via the loadTranslations() function) must now use MessageId for the translation key rather than the previous SourceMessage string.
  • ivy: To attach the $localize function to the global scope import from @angular/localize/init. Previously it was @angular/localize. To access the loadTranslations() and clearTranslations() functions, import from @angular/localize. Previously it was @angular/localize/run_time.
  • bazel: Angular bazel users using protractor_web_test_suite from @angular/bazel npm package should now switch to the @bazel/protractor npm package.

This should impact very few users and the user's that are impacted have a very easy upgrade path to switch to fetching the protractor_web_test_suite rule via the @bazel/protractor npm package.

  • ivy: This commit removes the public export of hasBeenProcessed().

This was exported to be availble to the CLI integration but was never used. The change to the function signature is a breaking change in itself so we remove the function altogether to simplify and lower the public API surface going forward.

  • core: Injector.get now accepts abstract classes to return type-safe values. Previous implementation returned any through the deprecated implementation.
  • Angular now compiles with Ivy by default (#32219) (ec4381d).

If you aren't familiar with Ivy, read our blog post about the Ivy preview and see the list of changes here.

  • ivy: make Hammer support tree-shakable. Previously, in Ivy applications, Hammer providers were included by default. With this commit, apps that want Hammer support must import HammerModulein their root module. (#32203) (de8ebbd)

DEPRECATIONS

  • core: TestBed.get function is marked as deprecated, use TestBed.inject instead.

DEPRECATIONS

  • core: deprecate integration with the Web Tracing Framework (WTF) (#30642) (b408445)
  • platform-webworker: deprecate platform-webworker (#30642) (361f181)
  • TestBed.get() has two signatures, one which is typed and another which accepts and returns any. The signature for any is deprecated; all usage of TestBed.get() should go through the typed API. This mainly affects string tokens (which aren't supported) and abstract class tokens.

Before:

TestBed.configureTestingModule({ providers: [{provide: "stringToken", useValue: new Service()}], }); let service = TestBed.get("stringToken"); // type any

After:

const SERVICE_TOKEN = new InjectionToken<Service>("SERVICE_TOKEN"); TestBed.configureTestingModule({ providers: [{provide: SERVICE_TOKEN, useValue: new Service()}], }); let service = TestBed.get(SERVICE_TOKEN); // type Service

BREAKING CHANGES

  • bazel: @bazel/typescript is now a peerDependency of @angular/bazel so users of @angular/bazel must add @bazel/typescript to their package.json

  • bazel: ng_module now depends on a minimum of build_bazel_rules_nodejs 0.27.12

  • core: In Angular version 8, it's required that all @ViewChild and @ContentChild queries have a 'static' flag specifying whether the query is 'static' or 'dynamic'. The compiler previously sorted queries automatically, but in 8.0 developers are required to explicitly specify which behavior is wanted. This is a temporary requirement as part of a migration; see static query migration guide for more details.

    @ViewChildren and @ContentChildren queries are always dynamic, and so are unaffected.

  • TestBed.get() has two signatures, one which is typed and another which accepts and returns any. The signature for any is deprecated; all usage of TestBed.get() should go through the typed API. This mainly affects string tokens (which aren't supported) and abstract class tokens.

    Before:

    TestBed.configureTestingModule({ providers: [{provide: "stringToken", useValue: new Service()}], }); let service = TestBed.get("stringToken"); // type any

    After:

    const SERVICE_TOKEN = new InjectionToken<Service>("SERVICE_TOKEN"); TestBed.configureTestingModule({ providers: [{provide: SERVICE_TOKEN, useValue: new Service()}], }); let service = TestBed.get(SERVICE_TOKEN); // type Service

  • core: Certain elements (like <tr> or <col>) require parent elements to be of a certain type by the HTML specification (ex. <tr> can only be inside <tbody> / <thead>). Before this change Angular template parser was auto-correcting "invalid" HTML using the following rules:

    • <tr> would be wrapped in <tbody> if not inside <tbody>, <tfoot> or <thead>;
    • <col> would be wrapped in <colgroup> if not inside <colgroup>.

    This mechanism of automatic wrapping / auto-correcting was problematic for several reasons:

    • it is non-obvious and arbitrary (ex. there are more HTML elements that have rules for parent type);
    • it is incorrect for cases where <tr> / <col> are at the root of a component's content, ex.:

    <projecting-tr-inside-tbody> <tr>...</tr> </projecting-tr-inside-tbody>

    In the above example the <projecting-tr-inside-tbody> component could be "surprised" to see additional <tbody> elements inserted by Angular HTML parser.

  • http: The deprecated @angular/http package has been removed, the @angular/common/http package should be used instead. For details on how to migrate, please refer to the deprecations guide.

  • TypeScript 3.1 and 3.2 are no longer supported.

    Please update your TypeScript version to 3.4, as version 3.3 is also not supported.

Possible Breaking Changes

  • animations: When animation is triggered within a disabled zone, the associated event (which an instance of AnimationEvent) will no longer report the totalTime as 0 (it will emit the actual time of the animation).

    To detect if an animation event is reporting a disabled animation then the event.disabled property can be used instead.

  • compiler: The <template> tag was deprecated in Angular v4 to avoid collisions (i.e. when using Web Components).

    This change removes support for <template>. <ng-template> should be used instead.

    BEFORE:

    <!-- html template --> <template>some template content</template> # tsconfig.json { # ... "angularCompilerOptions": { # ... # This option is no more supported and will have no effect "enableLegacyTemplate": [true|false] } }

    AFTER:

    <!-- html template --> <ng-template>some template content</ng-template>
  • core: it is no longer possible to import animation-related functions from @angular/core. All animation symbols must now be imported from @angular/animations.

  • forms: - AbstractControl#statusChanges now emits an event of 'PENDING' when you call AbstractControl#markAsPending

    • Previously it did not emit an event when you called markAsPending
    • To migrate you would need to ensure that if you are filtering or checking events from statusChanges that you account for the new event when calling markAsPending
  • forms: ngModelChange is now emitted after the value/validity is updated on its control.

    Previously, ngModelChange was emitted before its underlying control was updated. This was fine if you passed through the value directly through the $event keyword, e.g.

    <input [(ngModel)]="name" (ngModelChange)="onChange($event)"> onChange(value) { console.log(value); // would log updated value }

    However, if you had a handler for the ngModelChange event that checked the value through the control, you would get the old value rather than the updated value. e.g:

    <input #modelDir="ngModel" [(ngModel)]="name" (ngModelChange)="onChange(modelDir)"> onChange(ngModel: NgModel) { console.log(ngModel.value); // would log old value, not updated value }

    Now the value and validity will be updated before the ngModelChange event is emitted, so the same setup will log the updated value.

    onChange(ngModel: NgModel) { console.log(ngModel.value); // will log updated value }

    We think this order will be less confusing when the control is checked directly. You will only need to update your app if it has relied on this bug to keep track of the old control value. If that is the case, you should be able to track the old value directly by saving it on your component.

5.2.0 (2018-01-10)

Bug Fixes

Note: Due to an animation fix back in 5.1.1 (c2b3792) which allows for nested :leave queries to work within animation sequences, all elements that are dynamically inserted (*ngIf, *ngFor, etc…) now contain the special CSS class: “ng-star-inserted”. This may cause failures within unit tests if there are any assertions that match against element.className directly. (An easy fix for this is to match using a regular expression instead of asserting the className string directly.)

BREAKING CHANGES

  • compiler: Angular now requires TypeScript 2.4.x.
  • compiler: split compiler and core. @angular/platform-server now additionally depends on @angular/platform-browser-dynamic as a peer dependency. (#18683) (0cc77b4)
  • platformXXXX() no longer accepts providers which depend on reflection. Specifically the method signature went from Provider[] to StaticProvider[].

Example: Before:

[ MyClass, {provide: ClassA, useClass: SubClassA} ]

After:

[ {provide: MyClass, deps: [Dep1,...]}, {provide: ClassA, useClass: SubClassA, deps: [Dep1,...]} ]

NOTE: This only applies to platform creation and providers for the JIT compiler. It does not apply to @Component or @NgModule provides declarations.

Benchpress note: Previously Benchpress also supported reflective provides, which now require static providers.

I18n Changes (@angular/common)

Because of multiple bugs and browser inconsistencies, we have dropped the intl api in favor of data exported from the Unicode Common Locale Data Repository (CLDR). Unfortunately we had to change the i18n pipes (date, number, currency, percent) and there are some breaking changes.

I18n pipes:

  • Breaking change:

    • By default Angular now only contains locale data for the language en-US, if you set the value of LOCALE_ID to another locale, you will have to import new locale data for this language because we don't use the intl API anymore.
  • Features:

    • you don't need to use the intl polyfill for Angular anymore.
    • all i18n pipes now have an additional last parameter locale which allows you to use a specific locale instead of the one defined in the token LOCALE_ID (whose default value is en-US).
    • the new locale data extracted from CLDR are now available to developers as well and can be used through an API (which should be especially useful for library authors).
    • you can still use the old pipes for now, but their names have been changed and they are no longer included in the CommonModule. To use them, you will have to import the DeprecatedI18NPipesModule after the CommonModule (the order is important):

    import { NgModule } from '@angular/core'; import { CommonModule, DeprecatedI18NPipesModule } from '@angular/common'; @NgModule({ imports: [ CommonModule, // import deprecated module after DeprecatedI18NPipesModule ] }) export class AppModule { }

    Don't forget that you will still need to import the intl API polyfill if you want to use those deprecated pipes.

Date pipe

  • Breaking changes:

    • the predefined formats (short, shortTime, shortDate, medium, ...) now use the patterns given by CLDR (like it was in AngularJS) instead of the ones from the intl API. You might notice some changes, e.g. shortDate will be 8/15/17 instead of 8/15/2017 for en-US.
    • the narrow version of eras is now GGGGG instead of G, the format G is now similar to GG and GGG.
    • the narrow version of months is now MMMMM instead of L, the format L is now the short standalone version of months.
    • the narrow version of the week day is now EEEEE instead of E, the format E is now similar to EE and EEE.
    • the timezone z will now fallback to O and output GMT+1 instead of the complete zone name (e.g. Pacific Standard Time), this is because the quantity of data required to have all the zone names in all of the existing locales is too big.
    • the timezone Z will now output the ISO8601 basic format, e.g. +0100, you should now use ZZZZ to get GMT+01:00.
    Field typeFormatExample valuev4v5
    Eras Narrow A for AD G GGGGG
    Months Narrow S for September L MMMMM
    Week day Narrow M for Monday E EEEEE
    Timezone Long location Pacific Standard Time z Not available
    Timezone Long GMT GMT+01:00 Z ZZZZ
  • Features

    • new predefined formats long, full, longTime, fullTime.
    • the format yyy is now supported, e.g. the year 52 will be 052 and the year 2017 will be 2017.
    • standalone months are now supported with the formats L to LLLLL.
    • week of the year is now supported with the formats w and ww, e.g. weeks 5 and 05.
    • week of the month is now supported with the format W, e.g. week 3.
    • fractional seconds are now supported with the format S to SSS.
    • day periods for AM/PM now supports additional formats aa, aaa, aaaa and aaaaa. The formats a to aaa are similar, while aaaa is the wide version if available (e.g. ante meridiem for am), or equivalent to a otherwise, and aaaaa is the narrow version (e.g. a for am).
    • extra day periods are now supported with the formats b to bbbbb (and B to BBBBB for the standalone equivalents), e.g. morning, noon, afternoon, ....
    • the short non-localized timezones are now available with the format O to OOOO. The formats O to OOO will output GMT+1 while the format OOOO will be GMT+01:00.
    • the ISO8601 basic time zones are now available with the formats Z to ZZZZZ. The formats Z to ZZZ will output +0100, while the format ZZZZ will be GMT+01:00 and ZZZZZ will be +01:00.
  • Bug fixes

    • the date pipe will now work exactly the same across all browsers, which will fix a lot of bugs for safari and IE.
    • eras can now be used on their own without the date, e.g. the format GG will be AD instead of 8 15, 2017 AD.

Currency pipe

  • Breaking change:
    • the default value for symbolDisplay is now symbol instead of code. This means that by default you will see $4.99 for en-US instead of USD4.99 previously.
  • Deprecation:
    • the second parameter of the currency pipe (symbolDisplay) is no longer a boolean, it now takes the values code, symbol or symbol-narrow. A boolean value is still valid for now, but it is deprecated and it will print a warning message in the console.
  • Features:
    • you can now choose between code, symbol or symbol-narrow which gives you access to more options for some currencies (e.g. the canadian dollar with the code CAD has the symbol CA$ and the symbol-narrow $).

Percent pipe

  • Breaking change
    • if you don't specify the number of digits to round to, the local format will be used (and it usually rounds numbers to 0 digits, instead of not rounding previously), e.g. {{ 3.141592 | percent }} will output 314% for the locale en-US instead of 314.1592% previously.

Deprecated code

  • compiler: The method ngGetContentSelectors() has been removed as it was deprecated since v4. Use ComponentFactory.ngContentSelectors instead.

Bug Fixes

Features

  • common: support as syntax in template/* bindings (#15025) (c10c060), closes #15020

  • upgrade: use ComponentFactory.inputs/outputs/ngContentSelectors (a3e32fb)
  • introduce source maps for templates (#15011) (cdc882b)

BREAKING CHANGES

  • Previously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly.

    Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above.

    This also makes all useValue providers eager, which should have no observable impact other than code size.

    EXPECTED IMPACT: Making providers eager was an incorrect behavior and never documented. Also, providers that are used by a directive / pipe / ngModule stay eager. So the impact should be rather small.

  • DebugNode.source no longer returns the source location of a node.

    Closes 14013

  • core: (since v4 rc.1)

    • Renderer2.setStyle no longer takes booleans but rather a bit mask of flags.

4.0.0-rc.1 (2017-02-24)

We are excited to share 4.0.0-RC.1 with the community. This is a feature-complete pre-release of 4.0.0. Upgrade to get to know the new features to be released in 4.0.0, and to help us validate the release.

It’s important to note that this release has been tested extensively. All Angular applications within Google use the master branch of Angular, so every commit is tested and validated at scale prior to any release.

We Need Your Help

Please give this RC a try and test it with your projects! We have spent a significant amount of time working to ensure that this release is backwards compatible and will work with your existing code, but you may have use cases we haven’t anticipated. If you are broken by this release, let us know so that we can look into it right away. We are also looking for feedback related to the ergonomics of any newly added APIs.

What’s New

View Engine

We’ve made changes under the hood to what AOT generated code looks like. These changes should reduce the size of the generated code for your components by more than half in some cases. Read the Design Doc for the View Engine updates.

Enhanced *ngIf syntax

Our template binding syntax now supports a couple helpful changes. You can now use an if/else style syntax, and assign local variables such as when unrolling an observable.

<ng-template #loading>Loading...</ng-template> <div *ngIf="userObservable | async; else loading; let user"> {{ user.name }} </div>

Animation Package

We have pulled Animations into their own package. This means that if you don’t use Animations, this extra code will not end up in your production bundles. This also allows you to more easily find documentation and to take better advantage of autocompletion. If you do need animations, libraries like Material will automatically import the module (once you install it via NPM), or you can add it yourself to your main NgModule.

TypeScript 2.1

We’ve updated Angular to a more recent version of TypeScript. This will improve the speed of ngc and you will get better type checking throughout your application.

StrictNullChecks

Angular is now compliant with TypeScript’s StrictNullChecks. This means that you can enable StrictNullChecks in your project, if desired.

Universal

Universal, the project that allows developers to run Angular on a server, is now up to date with Angular again, and has been adopted by the Angular team. This release now includes the results of the work from the Universal team over the last few months. The majority of the Universal code is now in platform-server. To learn more about this change, take a look the new renderModuleFactory method, or Rob Wormald’s Demo Repository. More documentation is forthcoming.

 

Flat ES Modules (Flat ESM / FESM)

We now ship flattened versions of our modules ("rolled up" version of our code in the EcmaScript Module format, see example file). This format should help tree-shaking, help reduce the size of your generated bundles, and speed up build, transpilation, and loading in the browser in certain scenarios.

ES2015 Builds

We now also ship our packages in the ES2015 Flat ESM format. This option is experimental and opt-in (configure your webpack to resolve "es2015" property in package.json over the regular "module" property).

Known Issues

The following is a list of known issues that will be fixed in the next rcs.

  • Source maps are missing in npm packages
  • Generated bundles will be larger temporarily while we validate new code paths and remove old ones
  • angular.io docs have not been updated to reflect API changes in 4.0
  • legacy UMD bundles don't have correct RxJS mappings when running in ES5 mode without a module system

Installing RC.1

We have two main ways to update. If you have an existing project, you should be able to run:

On Linux/Mac: npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@next --save On Windows: npm install @angular/common@next @angular/compiler@next @angular/compiler-cli@next @angular/core@next @angular/forms@next @angular/http@next @angular/platform-browser@next @angular/platform-browser-dynamic@next @angular/platform-server@next @angular/router@next @angular/animations@next --save

Then run whatever ng serve or npm start command you normally use, and everything should work.

Please ensure that you are using Typescript v2.1.6 or higher.

If you rely on Animations you’ll also need to install the animations package @angular/animations and import the new BrowserAnimationsModule from @angular/platform-browser/animations in your root NgModule. Without this, your code will compile and run, but animations won’t activate. Imports from @angular/core were deprecated, use imports from the new package import { trigger, state, style, transition, animate } from '@angular/animations';.

What's next?

We have three more release candidates scheduled before our planned GA the week of March 22. In the meantime we'll be looking for your feedback, fixing bugs and working on docs.

BREAKING CHANGES

  • core: Because all lifecycle hooks are now interfaces the code that uses 'extends' keyword will no longer compile. Introduced by (ee747f7).

    To migrate the code follow the example below:

    Before:

    @Component() class SomeComponent extends OnInit {}

    After:

    @Component() class SomeComponent implements OnInit {}

    Based on our research we don't expect anyone to be affected by this change.

  • RootRenderer cannot be used any more, use RendererFactoryV2 instead. Introduced by (ccb636c).

    Note: Renderer can still be injected/used, but is deprecated.

Note: the 4.0.0-rc.0 release on npm accidentally omitted one bug fix, so we cut rc.1 instead. oops :-)

DEPRECATIONS

  • core: KeyValueDifferFactory and IterableDifferFactory no longer have ChangeDetectorRef as a parameter. It was not used and has been there for historical reasons. If you call DifferFactory.create(...) remove the ChangeDetectorRef argument. Introduced by (#14311).

BREAKING CHANGES

  • common: Classes that derive from AsyncPipe and override transform() might not compile correctly. The much more common use of async pipe in templates is unaffected. We expect no or little impact on apps from this change, file an issue if we break you. Introduced by (#14367) (4da7925).

    • Mitigation: Update derived classes of AsyncPipe that override transform() to include the type parameter overloads.

Performance Improvements

  • use abstract keyword where possible to decrease file size. (#14112) (670b680)
  • core simplify ReflectiveInjector by removing code for Dart implementation (#14126) (670b680)

BREAKING CHANGES

  • common: A definition of Iterable<T> is now required to correctly compile Angular applications. Support for Iterable<T> is not required at runtime but a type definition Iterable<T> must be available.

NgFor, and now NgForOf<T>, already supports Iterable<T> at runtime. With this change the type definition is updated to reflect this support.

Migration:

  • add "es2015.iterable.ts" to your tsconfig.json "libs" fields.

Part of #12398

  • upgrade: Previously, upgrade/static/downgradeInjectable returned an array of the form:

['dep1', 'dep2', ..., function factory(dep1, dep2, ...) { ... }]

Now it returns a function with an $inject property:

factory.$inject = ['dep1', 'dep2', ...]; function factory(dep1, dep2, ...) { ... }

It shouldn't affect the behavior of apps, since both forms are equally suitable to be used for registering AngularJS injectable services, but it is possible that type-checking might fail or that current code breaks if it relies on the returned value being an array.

4.0.0-beta.5 (2017-01-25)

Bug Fixes

Features

  • build: optionally build an ES2015 distro (#13471) (be6c95a)
  • core: add event support to view engine (0adb97b)
  • core: add initial view engine (#14014) (2f87eb5)
  • core: add pure expression support to view engine (6541737)

  • tsc-wrapped: Support of vinyl like config file was added (#13987) (0c7726d)
  • upgrade: Support ng-model in downgraded components (#10578) (e21e9c5)

DEPRECATIONS

  • OpaqueToken is now deprecated, use InjectionToken<T> instead.
  • Injector.get(token: any, notFoundValue?: any): any is now deprecated use the same method which is now overloaded as Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;

BREAKING CHANGES

  • core: - Because injector.get() is now parameterize it is possible that code which used to work no longer type checks. Example would be if one injects Foo but configures it as {provide: Foo, useClass: MockFoo}. The injection instance will be that of MockFoo but the type will be Foo instead of any as in the past. This means that it was possible to call a method on MockFoo in the past which now will fail type check. See this example:

class Foo {} class MockFoo extends Foo { setupMock(); } var PROVIDERS = [ {provide: Foo, useClass: MockFoo} ]; ... function myTest(injector: Injector) { var foo = injector.get(Foo); // This line used to work since `foo` used to be `any` before this // change, it will now be `Foo`, and `Foo` does not have `setUpMock()`. // The fix is to downcast: `injector.get(Foo) as MockFoo`. foo.setUpMock(); }

Bug Fixes

Performance Improvements

  • animations: always run the animation queue outside of zones (e2622ad), closes #13440

Note

Due to regression in the 2.3.0 release that was fixed by #13464, components that have been compiled using 2.3.0 and published to npm will need to be recompiled and republished.

The >=2.3.1 compiler will issue is the following error if it encounters components compiled with 2.3.0: Unsupported metadata version 2 for module ${module}. This module should be compiled with a newer version of ngc.

We are adding more tests to our test suite to catch these kinds of problems before we cut a release.

2017년과 이후 JavaScript의 동향 - 브라우저 밖의 JavaScript


참고 : http://developer.telerik.com/topics/web-development/javascripts-journey-2016/



2017년 전망은?

기존의 빌드 도구도 어느 정도의 역할을 수행하겠지만 전체적으로 webpack으로 전환이 이루어질 것으로 예측된다. 다양한 배포 전략에 따라 원하는 빌드를 구성할 수 있다는 장점은 물론 webpack에서 제공되거나 오픈소스로 추가되는 로더와 플러그인의 수많은 기능이 webpack과 빌드 도구의 격차를 더 벌릴 것으로 보인다.

브라우저를 넘어서다

전통적으로 JavaScript는 항상 브라우저에서만 실행할 수 있다고 인식돼 왔다. 그러나 이제는 그런 인식은 맞지 않는 것임을 누구나 알고 있다. Node.js를 통해 브라우저 밖의 영역으로 JavaScript가 확장하면서 다양한 가능성이 나타나고 있다. 이 장에서는 JavaScript를 멀티 플랫폼에서 단일 개발 언어로 사용할 수 있는 가능성을 살펴본다.

이 장의 주요 내용은 브라우저 이외의 영역에서 2017년의 JavaScript 기술과 전망을 살펴보는 글인 "JavaScript in 2017 – Beyond the Browser"를 참고로 했다.

Node.js

Node.js

Node.js는 오픈소스 런타임 라이브러리로, 서버사이드 애플리케이션과 브라우저 바깥 환경에서 실행되는 JavaScript 애플리케이션을 만드는 데 도움을 준다. 지난 수년간 주로 스타트업에서 사용되며 인기를 얻었고 점차 주요 기업체로 영향력을 확대해 왔다.

패키지 관리자인 npm의 저장소는 서버사이드 애플리케이션에서 사용할 수 있는 유틸리티 모듈들을 호스팅하는 역할에서 배포 가능한 JavaScript 코드의 표준 저장소로 변모하고 있다.

Module Counts 사이트에서 조사한 바로는 2017년 1월부터 5월 말까지 8만 3천여 개의 새로운 모듈이 등록됐다(5월 24일 기준, 총 458,275개 모듈). 매달 1만 6천여 개 이상의 모듈이 등록되는 수준이다. 영역에 국한하지 않고 살펴보더라도 npm에 등록된 모듈의 수가 다른 언어나 플랫폼에 등록된 모듈의 수보다 압도적으로 많다는 것을 확인할 수 있다.

그림 4 언어별 모듈 개수 통계

그림 4 언어별 모듈 개수 통계(원본 출처: Module Counts)

이러한 증가세에는 여러 이유가 있겠지만 하나를 꼽자면 엔터프라이즈 기업에서의 Node.js 사용 증가라 할 수 있다. 이는 단순히 사용된다는 의미에서 벗어나 안정성이 요구되는 영역에서 검증된 제품이라는 의미기도 하다. Node.js의 적용 사례 페이지에서는 잘 알려진 다양한 기업의 이름을 볼 수 있다. NASA와 같이 고도의 안정성이 요구되는 분야에서도 Node.js가 사용된다.

"When you've got the safety of astronauts on the line, little hiccups and service interruptions turn into life-and-death situations. From EVA [extra vehicular activity] data to astronauts up in space, Node.js helps ensure there's a safe home for everything and everyone." 
(우주 비행사의 안전이 위태로울 때는 사소한 고장이나 서비스 장애가 생과 사를 가를 수 있다. Node.js는 선외 활동(EVA) 데이터는 물론 우주 공간에 있는 우주 비행사까지 모두 안전할 것이라는 것을 보장해 준다.) 
— Node.js Helps NASA Keep Astronauts Safe and Data Accessible

2017년 전망은?

많은 기업이 전통적인 개발 접근 방법에서 Node.js로 전환할 것으로 예측된다. 특히 Microsoft가 발표한 JavaScript 확장 언어(superset)인 TypeScript는 JavaScript를 Java나 C# 개발자가 더 이해하기 쉬운 언어로 만들어 Node.js의 성장에 힘을 실어 줄 것으로 보인다.

다양한 개발 환경과 언어를 유지 보수하는 것을 싫어하는 큰 기업들은 개발 언어를 하나로 통합할 수 있게 하는 Node.js에 매력을 느낄 것이다.

PhoneGap과 Cordova

Cordova

PhoneGap과 Cordova는 JavaScript로 네이티브 모바일 애플리케이션을 개발하려 시도한 첫 오픈소스다. Cordova의 기본 접근 방법은 웹뷰(WebView)에서 웹 코드를 감싸고, 웹뷰를 통해 네이티브 모바일 애플리케이션을 구동하는 것이다.

웹뷰에 관한 더 자세한 내용은 "What is a WebView?"를 참고한다.

이 접근 방법은 웹 개발자가 이미 알고 있는 웹 기술(주로 JavaScript)을 사용할 수 있게 한다. 그래서 수 년 동안 모바일 애플리케이션 개발 영역에서 강력한 위치를 유지할 수 있었다. 그러나 "2016년과 이후 JavaScript의 동향"에서 언급한 것처럼 Google의 Progressive Web Apps(PWA)의 강력한 도전을 받고 있는 상태다.

PWA는 네이티브 애플리케이션에서 사용하는 기능을 웹에서 사용할 수 있게 한다. 예를 들어 Push API와 Notifications API는 웹 애플리케이션에서 푸시 알림을 사용할 수 있게 한다. 그 외에 오프라인 상태에서 캐시를 사용할 수 있게 하는 서비스 워커(service worker), 스마트폰의 홈 화면에 웹 애플리케이션 아이콘을 등록하게 할 수 있는 웹 앱 매니페스트(web app manifest) 등의 기술이 있다.

2016년에 Google은 PWA에 많은 관심과 노력을 쏟았다. Google의 주요 개발자 콘퍼런스인 Chrome Dev Summit 2016에서는 총 25개 세션 가운데 9개 세션을 PWA 관련 세션으로 진행했다. 또 다른 주요 콘퍼런스인 Google I/O 2016에서도 많은 세션을 PWA 관련 세션으로 진행해 PWA 기술의 확산에 노력을 기울였다.

PWA를 활용한 애플리케이션 개발에 관한 더 자세한 내용은 "현실적 PWA"를 참고한다.

Cordova와 같은 하이브리드 애플리케이션 개발 방식 대신 PWA를 선택하는 개발자의 비율을 정확하게 계산하기는 어렵다. 그러나 많은 데이터가 Cordova의 사용량이 정체되거나 감소하고 있다는 사실을 나타내고 있다. npm-stat 사이트에서 지난 2년 동안(2015년 3월 17일~2017년 3월 17일)의 통계를 살펴보면 npm에서 Cordova의 다운로드 횟수는 2015년 12월에 50만으로 정점을 찍은 이후 30~40만 정도에 머물러 있다.

2017년 전망은?

하이브리드 애플리케이션 개발 방식의 매력은 점점 더 감소하고 있다. 한때 네이티브 애플리케이션 개발의 대안으로 여겨지기도 했지만 PWA와 같은 새로운 기술의 등장과 단일 도구를 통한 개발 효율성(시간 및 비용 측면)에 대한 욕구가 커지면서 관심도가 점차 낮아지고 있다.

2017년에도 상황이 뚜렷하게 바뀔 만한 요인은 보이지 않는다. Google I/O 2017의 "The Mobile Web: State of the Union" 세션에서 확인할 수 있듯이 Google은 모바일 웹 영역에서 AMP(Accelerated Mobile Pages)와 PWA에 힘을 싣고 있다. 하이브리드 애플리케이션 개발 방식의 입지는 점점 더 줄어들 수밖에 없을 것으로 보인다.

네이티브 모바일 애플리케이션

React Native와 NativeScript

JavaScript 주도적(JavaScript-driven) 네이티브 애플리케이션 개발은 Appcelerator의 Titanium이 개척하고 선도했던 영역이다. 현재는 React Native와 NativeScript가 그 자리를 점점 대체하고 있다.

웹뷰를 감싸는 형태의 Cordova와는 다르게 JavaScript 주도적 네이티브 애플리케이션 개발은 웹뷰를 사용하지 않는다. 그렇기 때문에 웹 기반 개발에서 일어나는 성능 문제에 영향을 받지 않는다.

npm-stat 사이트에서 지난 1년 동안의 다운로드 통계를 살펴보면 React Native의 성장세가 확실히 두드러진다. NativeScript의 다운로드 횟수는 완만하게 상승하다가 2017년 3월에 정점을 찍은 후 조금은 하락하는 모습을 보이고 있다.

2017년 전망은?

더욱더 많은 JavaScript 개발자가 모바일 애플리케이션을 개발하게 되면서 JavaScript 주도적 네이티브 애플리케이션 개발은 지속적으로 성장할 것으로 예측된다.

React의 인기를 업은 React Native는 React로 개발한 애플리케이션을 손쉽게 네이티브 애플리케이션으로 전환하는 방법을 제공한다. 성능에서도 네이티브 애플리케이션에 뒤지지 않아 React Native로 개발한 iOS 애플리케이션이 Swift로 개발한 네이티브 애플리케이션보다 더 나은 성능을 보인다는 사례도 있다("Comparing the Performance between Native iOS (Swift) and React-Native" 참고).

2016년 5월에 NativeScript가 Angular 2 지원을 발표하면서("Sharing Code Between Web and Native Apps" 참고) 대표적인 JavaScript 프레임워크 모두에서 단일한 코드를 기반으로 웹과 네이티브 모바일 애플리케이션을 개발할 수 있게 됐다. 이는 개발자와 기업 모두에게 매우 매력적인 일이다.

데스크톱 애플리케이션

Electron과 NW.js

데스크톱 영역에서 JavaScript를 사용할 수 있는 방법은 그리 많지 않다. Electron과 NW.js가 대표 주자로 이 영역을 이끌어 가고 있다.

Electron과 NW.js 모두 성장했지만 Electron이 점점 실질적인 표준(de-facto)으로서의 위치를 굳혀 가고 있다. Electron은 Microsoft의 Visual Studio Code 개발에 사용된 이후 많은 데스크톱 애플리케이션 개발 도구로 사용되고 있다. Electron은 또한 React 커뮤니티와 Angular 커뮤니티의 지지를 동시에 받는 흔치 않은 모습을 보일 정도로 이 영역에서는 독보적인 위치를 구축하고 있다.

2017년 전망은?

Electron이 2017년에도 압도적인 우위를 보일 것이라 예측하는 것이 전혀 이상하지 않다. React와 Angular 같은 인기 있는 프레임워크의 지원도 예상된다. JavaScript가 Java와 Microsoft 기반 기술(WPF)이 차지하고 있는 영역을 서서히 침범하고 있어 기존 기술을 대체하는 역할이 점점 더 커질 것으로 보인다.

JavaScript의 새로운 영역

앞으로 등장하거나 각광을 받을 기술을 꼽으라면 빠지지 않고 등장하는 기술이 있다. 바로 챗봇(chatbot)과 사물 인터넷(IoT, Internet of things), 가상현실(virtual reality)이다.

챗봇

챗봇 프레임워크

챗봇 생태계에서 JavaScript의 영향력은 크다. 많은 개발자가 JavaScript로 챗봇을 개발하고 있다. 그 외에 단순한 Slack 봇부터 복잡한 상거래용 봇까지 다양한 챗봇을 개발한다.

다양한 유형의 챗봇에 관해서는 "11 Examples of Conversational Commerce and Chatbots"를 참고한다.

또한 Botkit, Microsoft의 Bot Framework, Facebook의 Wit.ai 등 챗봇 프레임워크의 대부분은 SDK에 Node.js 라이브러리를 포함하고 있다.

사물 인터넷

사물 인터넷 라이브러리

사물 인터넷인 IoT 영역에서도 JavaScript를 쉽게 볼 수 있다.

IoT 라이브러리인 Losant와 Zetta는 Node.js API를 제공한다. 가상현실 컨트롤러 기기로 유명한 립모션은 JavaScript API를 제공한다. 삼성은 웹 기반의 IoT 플랫폼 구축을 위한 IoT 엔진인 JerryScript를 2015년에 발표했다.

가상현실

가상현실 프레임워크

웹의 가상현실 기술 표준화는 WebVR을 통해 진행되고 있다. WebVR API는 JavaScript로 가상현실 기기(Oculus의 Rift와 같은 HMD(head mounted display) 등)에서 감지되는 위치와 움직임 등에 대한 정보를 얻을 수 있게 한다.

Google의 Chrome 팀은 실험적이면서 인상적인 가상현실 예제를 Chrome Experiments for Virtual Reality 사이트에 공개하고 있다. Mozilla는 2015년 중반부터 가상현실 경험을 개발할 수 있는 프레임워크인 A-Frame을 개발하고 있다. Microsoft는 자사의 가상현실 기기인 HoloLens에서 사용할 수 있는 애플리케이션 개발을 위한 프레임워크인 HoloJS를 2016년 12월에 공개했다.

2017년 전망은?

JavaScript의 유명세와 인기는 2017년에도 다양한 영역에서 이어질 것이라 예상된다. 다양한 환경에 JavaScript가 침투하고, 새로 등장할 개발 생태계에서도 JavaScript는 주요 언어가 될 것으로 보인다.

마치며

10년 전에는 JavaScript의 현재 모습을 결코 생각할 수 없었다. 곧 생명력이 다할 것처럼 보이는 시기마다 상황을 전환하는 다양한 플랫폼과 프레임워크가 때맞춰 등장했고, 이제는 다양한 영역에서 JavaScript가 사용되고 있다. JavaScript가 모든 영역에서 사용되거나 기존 개발 언어를 대체하지는 않겠지만, 범용적인 사용성 때문에 개발 영역에서 주요한 자리를 차지하고 있다는 점에는 의심의 여지가 없어 보인다.

스탠퍼드 대학교의 컴퓨터공학 학부는 JavaScript로 기본 프로그래밍 방법론을 가르치는 "CS106J: Programming Methodologies in JavaScript" 과정을 2017년 봄에 시험적으로 개설했다("CS department updates introductory courses" 참고)했다. 기존의 기본 프로그래밍 방법론 과정인 "CS 106A: Programming Methodology"에서 사용하는 언어는 Java인데, JavaScript가 이를 대체할 가능성이 있다("Stanford CS department updates introductory courses: Java is Gone" 참고). 이런 변화는 학문적인 영역에서도 JavaScript의 미래에 대한 가능성을 염두에 두고 있다는 것을 보여 주는 일이기도 하다.

개발자라면 누구나 아는 질의, 응답 사이트인 Stack Overflow의 공동 창업자 중 한 명인 Jeff Atwood는 현재와 같은 상황을 미리 예견했는지도 모르겠다. Jeff Atwood는 2007년에 블로그에서 다음과 같은 'Atwood의 법칙'을 이야기했다("The Principle of Least Power" 참고).

Any application that can be written in JavaScript, will eventually be written in JavaScript. 
(JavaScript로 작성될 수 있는 애플리케이션은 결국 모두 JavaScript로 작성될 것이다.)
