问题描述
我不知道何时使用 require('jslib') 与 <script src=""></script>电子内容页面(例如 index.html).使用jQuery，我发现需要按如下方式加载:
<script>window.$ = window.jQuery = require('./js/jquery-2.2.4.min.js');</script>我需要开始使用其他一些库(例如 Handlebars、ds3.js、Bootstrap 等)，我不确定是否应该使用 <script> 标签加载这些库，或者如果我应该要求他们.
在模块捆绑器之前，必须通过 <script> 标记或通过模块加载器(例如
那么你应该使用哪种方法呢?
Electron 公开了原生 Node.js require 函数.不利用这一点将是一种耻辱:您可以按名称要求包，并将您的代码拆分为可重用的模块，就像在任何 Node.js 应用程序中所做的那样.
I don't have a handle on when to use require('jslib') versus <script src=""></script> in Electron content pages (e.g. index.html). With jQuery, I discovered that it needs to be loaded as follows:
<script>window.$ = window.jQuery = require('./js/jquery-2.2.4.min.js');</script>
I need to start using some other libraries (e.g. Handlebars, ds3.js, Bootstrap, etc.) and I am not sure if I should be loading those with the <script> tag or if I should require them.
Before module bundlers, libraries would have to be imported either via a <script> tag or via module loaders such as RequireJS.
Now it's easier to assume a CommonJS environment and get everything through a module bundler which will expose a require function for you in a browser context.
All of this is not necessary in the context of an Electron app:
In normal browsers, web pages usually run in a sandboxed environment and are not allowed access to native resources. Electron users, however, have the power to use Node.js APIs in web pages allowing lower level operating system interactions.
Cf. renderer process
That means that the native Node.js require function (amongst other things) is available in your renderer process!
Here's a simple Electron app to prove it:
My package.json:
{
"name": "foobar",
"version": "1.0.0",
"main": "main.js",
"scripts": {
"start": "electron ."
},
"devDependencies": {
"electron": "^3.0.7"
},
"dependencies": {
"the-answer": "^1.0.0"
}
}
My main.js: (the main process)
const {app, BrowserWindow} = require('electron');
let mainWindow;
function createWindow () {
mainWindow = new BrowserWindow({width: 800, height: 600})
mainWindow.loadFile('index.html');
}
app.on('ready', createWindow);
My index.html: (the renderer process)
<!DOCTYPE html>
<html>
<body>
<script>
const os = require('os'); // Standard Node.js module
const answer= require('the-answer'); // An NPM package that returns the answer to everything.
</script>
<button onclick="alert(os.platform())">YOUR PLATFORM</button>
<button onclick="alert(answer)">THE ANSWER</button>
</body>
</html>
So which method should you use?
Electron exposes the native Node.js require function. It would be a shame not to leverage this: you would be able to require packages by their names and split your code into reusable modules as you would do in any Node.js apps.
