# NW.js와 기술적으로 다른점 (이전 node-webkit)
|
||
|
|
||
|
__알림: Electron은 이전까지 Atom Shell로 불려졌습니다.__
|
||
|
|
||
|
Like NW.js, Electron provides a platform to write desktop applications
|
||
|
with JavaScript and HTML and has Node integration to grant access to low level
|
||
|
system in web pages.
|
||
|
|
||
|
But there are also fundamental differences between the two projects that make
|
||
|
Electron a completely separate product from NW.js:
|
||
|
|
||
|
__1. 어플리케이션의 엔트리 포인트__
|
||
|
|
||
|
In NW.js, the main entry of an application is a web page. You specify a
|
||
|
main page in the `package.json` and it is opened in a browser window as
|
||
|
the application's main window.
|
||
|
|
||
|
In Electron, the entry point is a JavaScript script. Instead of
|
||
|
providing a URL directly, you manually create a browser window and load
|
||
|
an HTML file using the API. You also need to listen to window events
|
||
|
to decide when to quit the application.
|
||
|
|
||
|
Electron works more like the Node.js runtime. Electron's APIs are lower level
|
||
|
so you can use it for browser testing in place of [PhantomJS](http://phantomjs.org/).
|
||
|
|
||
|
__2. 빌드 시스템__
|
||
|
|
||
|
In order to avoid the complexity of building the whole Chromium, Electron uses
|
||
|
[libchromiumcontent](https://github.com/brightray/libchromiumcontent) to access
|
||
|
Chromium's Content API. libchromiumcontent is a single, shared library that
|
||
|
includes the Chromium Content module and all its dependencies. Users don't
|
||
|
need a powerful machine to build Electron.
|
||
|
|
||
|
__3. Node 통합__
|
||
|
|
||
|
In NW.js, the Node integration in web pages requires patching Chromium to
|
||
|
work, while in Electron we chose a different way to integrate libuv loop with
|
||
|
each platform's message loop to avoid hacking Chromium. See the
|
||
|
[`node_bindings`](../../atom/common/) code for how that was done.
|
||
|
|
||
|
__4. 다중 컨텍스트__
|
||
|
|
||
|
If you are an experienced NW.js user, you should be familiar with the
|
||
|
concept of Node context and web context. These concepts were invented because
|
||
|
of how NW.js was implemented.
|
||
|
|
||
|
By using the [multi-context](http://strongloop.com/strongblog/whats-new-node-js-v0-12-multiple-context-execution/)
|
||
|
feature of Node, Electron doesn't introduce a new JavaScript context in web
|
||
|
pages.
