webpack4 构建vue多页工程
多页应用开发环境配置
构建开发环境的配置，需要使用到webpack-dev-server，以及webpack4中的mode配置和devServer。
而多页应用的开发则需要使用到html-webpack-plugin这个插件，来构建html
项目的目录结构
-- src
|-- views
|-- home
|-- index.js
|-- index.html
|-- index.vue
多页面的entry和页面的构建打包
const setMPA = () => {
const entrys = {};
const htmlWebpackPlugins = [];
const entryFiles = glob.sync(path.join(__dirname, "src"));
Object.keys(entryFiles)
.map((index) => {
const entry = entryFiles[index];
const match = entry.match(/src\/views\/(.*)\/index\.js/);
const pageName = match && match[1];
entrys[pageName] = entry;
htmlWebpackPlugins(
new HtmlWebpackPlugin({
fileName: `${pageName}.html`,
template: path.join(__dirname, `src/views/${pageName}/index.html`),
title: `${pageName} title`
})
)
})
return {
entrys,
htmlWebpackPlugins
}
}
webpack.dev.js 开发环境的配置
// webpack.dev.js
const path = require('path');
const glob = require('glob');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const VueLoaderPlugin = require('vue-loader/lib/plugin');
const webpack = require('webpack');
const setMPA = () => {
const entrys = {};
const htmlWebpackPlugins = [];
const entryFiles = glob.sync(path.join(__dirname, "src"));
Object.keys(entryFiles)
.map((index) => {
const entry = entryFiles[index];
const match = entry.match(/src\/views\/(.*)\/index\.js/);
const pageName = match && match[1];
entrys[pageName] = entry;
htmlWebpackPlugins(
new HtmlWebpackPlugin({
fileName: `${pageName}.html`,
template: path.join(__dirname, `src/views/${pageName}/index.html`),
title: `${pageName} title`
})
)
})
return {
entrys,
htmlWebpackPlugins
}
}
const { entrys, htmlWebpackPlugins } = setMPA();
module.exports = {
mode: 'development',
entry: entrys,
output: {
filename: 'static/js/[name].js',

babelrc的配置，应用与编译ES的语法
/* .babelrc */
{
"presets": [
"@babel/perset-env"
]
}
浏览器的兼容版本，>1%==市场的使用份额大于1%
/* .browserslistrc */

正式环境配置
vue的正式环境需要配置mode: production，默认开启UglifyJsPlugin（js代码压缩）。
正式环境的资源hash迭代（hash、chunkhash、contenthash）
使用loader配置资源的提取，针对样式的提取使用mini-css-extract-plugin插件去提取，配合html-webpack-plguin把提取出来的css[chunk]配置进去html中
告警信息人性化，使用插件@soda/friendly-errors-webpack-plugin，
/**
* font and image 资源 --> hash
* 从js提取出font和image资源
*/
module.exports = {
module: {
rules: [
{
test: /\.(png|jpe?g|gif|svg)$/,
use: [
{
loader: 'url-loader',
options: {
name: '[name]_[hash:8].[ext]',
limit: 10240 // 10k https://www.npmjs.com/package/url-loader#limit
}
}
]
},
{
test: /\.(woff|woff2|eof|ttf|tof)$/,
use: [
{
loader: 'file-loader', // https://www.npmjs.com/package/file-loader#name
options: {
name: '[name]_[hash:8].[ext]' // https://www.npmjs.com/package/file-loader#placeholders
}
}
]
}
]
}
}
sass 预处理器，配置时需要注意, css 样式处理，使用到contenthash
/**
* css --> contenthash 当css的内容没有任何改变，不会随着js[chunkhash]的改变而改变
* 遵从js的chunkhash
* 从js中提取出css到文件中
*/
