tips: 本框架目前支持options和popup页面打包，background.js、content.js和devtool打包目前暂未适配。
背景
在开发完baymax插件之后，把常用的二维码、网址链接也加到这个插件里了，以后还肯能会添加更多功能，就让这个插件变得臃肿。便想着代码重构，把它做成可配置的，可以通过options页面配置想要的模块在popup中展示。既然要重构，便采用了比较新的webpack5、vue3、ts技术栈。
chrome插件开发和普通web开发的差异
差异有以下几点：
- chrome插件开发环境是多页面的，需要独立配置options、popup等页面
const chromeName = ['popup', 'options']
let entryObj = {}
chromeName.forEach(name => {
entryObj[name] = path.resolve(__dirname, `src/${name}/main.ts`)
})
const htmlWebpackPluginList = chromeName.map(name => {
return new HtmlWebpackPlugin({
template: 'index.html',
filename: `${name}.html`,
chunks: [name]
})
})
const config ={
entry: entryObj,
plugins: [
...htmlWebpackPluginList,
]
}
- 另外manifest.json、静态资源也需要复制到最终输出的目录中
const fileCopyList = [
{
from: path.resolve('src/manifest.json'),
to: `${path.resolve('dist')}/manifest.json`
},
{
from: path.resolve('src/assets/logo.png'),
to: `${path.resolve('dist')}/img/logo.png`
},
{
from: path.resolve('src/background/background.js'),
to: `${path.resolve('dist')}/js/background.js`
},
{
from: path.resolve('src/content/content.js'),
to: `${path.resolve('dist')}/js/content.js`
},
]
{
new CopyWebpackPlugin({patterns: fileCopyList}),
}
- 热更新的差异，普通web开发输出的资源是在内存中，chrome插件开发则要输出到磁盘中，另外需要设置disableHostCheck: true,跳过host检查，open: false,避免自动打开网页。
devServer: {
contentBase: false,
// publicPath: './dist',
hot: true,
port: 8080,
open: false,
lazy: false,
// hotOnly: true,
disableHostCheck: true,
compress: true,
overlay: true,
writeToDisk: true,
},
完整的webpack配置如下：
const path = require('path');
const { HotModuleReplacementPlugin, IgnorePlugin } = require('webpack');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { VueLoaderPlugin } = require('vue-loader');
const ForkTsCheckerWebpackPlugin = require('fork-ts-checker-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin')
const chromeName = ['popup', 'options']
const fileCopyList = [
{
from: path.resolve('src/manifest.json'),
to: `${path.resolve('dist')}/manifest.json`
},
{
from: path.resolve('src/assets/logo.png'),
to: `${path.resolve('dist')}/img/logo.png`
},
{
from: path.resolve('src/background/background.js'),
to: `${path.resolve('dist')}/js/background.js`
},
{
from: path.resolve('src/content/content.js'),
to: `${path.resolve('dist')}/js/content.js`
},
]
let entryObj = {}
chromeName.forEach(name => {
entryObj[name] = path.resolve(__dirname, `src/${name}/main.ts`)
})
const htmlWebpackPluginList = chromeName.map(name => {
