Electron uses Node native modules

In this section we learn how to use the Node native module Electron

Electron support native Node module, but the official and Node comparison, Electron possible to use a system and we have installed Node different V8 engine, the module used need to be recompiled to use. If we want to compile a native module, we need to manually set the location of Electron of headers

How to install native modules

There are three ways to install native modules, they are:

• Install and recompile the module for Electron
• Install native modules through npm
• Manually compile for Electron

Install and recompile the module for Electron

The easiest way is to Electron electron-rebuild package. The module can automatically determine Electron , and process the steps of downloading headers and rebuilding the native module for the application.

Example:

For example, electron-rebuild , you first need to install electron-rebuild :

npm install --save-dev electron-rebuild

Every time npm install is run, the following command will be run at the same time:

./node_modules/.bin/electron-rebuild

If you encounter problems with the above commands under windows , you can try to execute the following commands:

.\node_modules\.bin\electron-rebuild.cmd

Install via npm

We can also install native modules directly npm Most of the steps are the same as when installing ordinary modules, but you need to set some system environment variables yourself.

Example:

For example, to install all the dependencies of Electron

# Electron的版本
export npm_config_target=1.2.3
# Electron的目标架构
export npm_config_arch=x64
export npm_config_target_arch=x64
# 下载Electron的headers
export npm_config_disturl=https://electronjs.org/headers
# 告诉node-pre-gyp我们是在为Electron生成模块
export npm_config_runtime=electron
# 告诉node-pre-gyp从源代码构建模块
export npm_config_build_from_source=true
# 安装所有依赖，并缓存到 ~/.electron-gyp
HOME=~/.electron-gyp npm install

Manually compile for Electron

Developers of native modules who want Electron may have to manually compile the Electron module. You can use node-gyp to compile directly.

Example:

For example, we want to tell node-gyp where to download Electron of headers , and what version to download:

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

• HOME=~/.electron-gyp : Set where to find headers during development.
• --target=0.29.1 : The version Electron
• --dist-url=... : Set the download address Electron of headers
• --arch=x64 : Set the module to compile for 64-bit operating system.
