详解webpack多入口配置与自动构建

//file build/webpack.base.conf.js
//entry 配置

module.exports = {
 entry: {
  app: './src/main.js'
 },
 //....

//file build/webpack.dev.conf.js
//html配置
  new HtmlWebpackPlugin({
   filename: 'index.html',
   template: 'index.html',
   inject: true
  })

//file build/webpack.base.conf.js
//entry 配置

module.exports = {
 entry: {
  'index': './src/view/index/index.js',
  'login': './src/view/login/login.js',
 },
 //....

//file build/webpack.dev.conf.js
//html配置,index我们保留了根目录访问路径
  new HtmlWebpackPlugin({
   filename: 'index.html',
   template: './src/view/index/index.html',
   inject: true,
   chunks: ['index']
  }),
  new HtmlWebpackPlugin({
   filename: 'login/login.html', //http访问路径
   template: './src/view/login/login.html', //实际文件路径
   inject: true,
   chunks: ['login']
  })

var glob = require('glob')
function getEntry(globPath, pathDir) {
  var files = glob.sync(globPath);
  var entries = {},
    entry, dirname, basename, pathname, extname;

  for (var i = 0; i < files.length; i++) {
    entry = files[i];
    dirname = path.dirname(entry);
    extname = path.extname(entry);
    basename = path.basename(entry, extname);
    pathname = path.join(dirname, basename);
    pathname = pathDir ? pathname.replace(pathDir, '') : pathname;
    console.log(2, pathname, entry);
    entries[pathname] = './' + entry;
  }
  return entries;
}
//我们的key不是简单用的上一个代码的index,login而是用的index/index,login/login因为考虑在login目录下面还有register
//文件路径的\\和/跟操作系统也有关系，需要注意
var htmls = getEntry('./src/view/**/*.html', 'src\\view\\');
var entries = {};
var HtmlPlugin = [];
for (var key in htmls) {
  entries[key] = htmls[key].replace('.html', '.js')
  HtmlPlugin.push(new HtmlWebpackPlugin({
   filename: (key == 'index\\index' ? 'index.html' : key + '.html'), 
   template: htmls[key],
   inject: true,
    chunks: [key]
  }))
}
