Electron应用发布

## Release

Using Native Node Modules

The native Node modules are supported by Electron, but since Electron is using a different V8 version from official Node, you have to manually specify the location of Electron’s headers when building native modules.

Native modules might break when Node starts using a new version of V8. To make sure the module you’re interested in will work with Electron, you should check if it supports the internal Node version used by Electron. You can check what version of Node is used in Electron by looking it up in the releases page or by using process.version (see Quick Start for example). Consider using NAN for your own modules, since it makes it easier to support multiple versions of Node. It’s also helpful for porting old modules to newer versions of Node so they can work with Electron.

The Easy Way

The most straightforward way to rebuild native modules is via the electron-rebuild package, which handles the manual steps of downloading headers and building native modules:

npm install --save-dev electron-rebuild


# Every time you run "npm install", run this
./node_modules/.bin/electron-rebuild


# On Windows if you have trouble, try:
.\node_modules\.bin\electron-rebuild.cmd

The npm Way

You can also use npm to install modules. The steps are exactly the same with Node modules, except that you need to setup some environment variables:

export npm_config_disturl=https://atom.io/download/atom-shell
export npm_config_target=0.33.1
export npm_config_arch=x64
export npm_config_runtime=electron
HOME=~/.electron-gyp npm install module-name

The node-gyp Way

To build Node modules with headers of Electron, you need to tell node-gyp where to download headers and which version to use:

$ cd /path-to-module/
$ HOME=~/.electron-gyp node-gyp rebuild --target=0.29.1 --arch=x64 --dist-url=https://atom.io/download/atom-shell

The HOME=~/.electron-gyp changes where to find development headers. The --target=0.29.1 is version of Electron. The --dist-url=... specifies where to download the headers. The --arch=x64 says the module is built for 64bit system.

### Executable File

为了使用Electron部署你的应用程序，你存放应用程序的文件夹需要叫做app并且需要放在Electron的资源文件夹下(在OS X中是指Electron.app/Contents/Resources/，在Linux和Windows中是指resources/)就像这样：

在OS X中:

electron/Electron.app/Contents/Resources/app/
├── package.json
├── main.js
└── index.html

在Windows和Linux中:

electron/resources/app
├── package.json
├── main.js
└── index.html

然后运行Electron.app(或者Linux中的electron，Windows中的electron.exe),接着Electron就会以你的应用程序的方式启动。electron文件夹将被部署并可以分发给最终的使用者。

### Package

除了通过拷贝所有的资源文件来分发你的应用程序之外，你可以可以通过打包你的应用程序为一个asar库文件以避免暴露你的源代码。

为了使用一个asar库文件代替app文件夹，你需要修改这个库文件的名字为app.asar，然后将其放到Electron的资源文件夹下，然后Electron就会试图读取这个库文件并从中启动。如下所示：

在OS X中:

electron/Electron.app/Contents/Resources/
└── app.asar

在Windows和Linux中:

electron/resources/
└── app.asar

Electron Packager:根据不同平台打包成.app或者.exe

Electron Packager is known to run on the following host platforms:

• Windows (32/64 bit)
• OS X
• Linux (x86/x86_64)

It generates executables/bundles for the following target platforms:

• Windows (also known as win32, for both 32/64 bit)
• OS X (also known as darwin) / Mac App Store (also known as mas)*
• Linux (for both x86/x86_64)

Running electron-packager from the command line has this basic form:

electron-packager <sourcedir> <appname> --platform=<platform> --arch=<arch> [optional flags...]

This will:

• Find or download the correct release of Electron
• Use that version of Electron to create a app in /-- (this can be customized via an optional flag)
