A multi-entry project scaffolding based on webpack2, mainly using extract-text-webpack-plugin to implement js and css public code extraction, html-webpack-plugin to implement html multi-entry, and less-loader to implement less compiles, postcss-loader configures autoprefixer to automatically add browser-compatible prefixes, html-withimg-loader implements adding image version numbers and template functions into HTML, babel-loader implements ES6 transcoding function, and happypack multi-threading accelerates the construction speed.

Get the multi-entry array according to the
JSdirectory
const ROOT = process.cwd(); // 根目录
let entryJs = getEntry('./src/js/**/*.js');
/**
* 根据目录获取入口
* @param {[type]} globPath [description]
* @return {[type]} [description]
*/
function getEntry (globPath) {
let entries = {};
Glob.sync(globPath).forEach(function (entry) {
let basename = path.basename(entry, path.extname(entry)),
pathname = path.dirname(entry);
// js/lib/*.js 不作为入口
if (!entry.match(/\/js\/lib\//)) {
entries[pathname.split('/').splice(3).join('/') + '/' + basename] = pathname + '/' + basename;
}
});
return entries;
}
// webpack 配置
const config = {
entry: entryJs,
output: {
filename: 'js/[name].js?[chunkhash:8]',
chunkFilename: 'js/[name].js?[chunkhash:8]',
path: path.resolve(ROOT, 'dist'),
publicPath: '/'
},
}Use babel to implement ES2015 to ES5, less to css and use postcss to implement autoprefixer to automatically add browser compatibility, url-loader to implement css to reference images and fonts and add version numbers, html -withimg-loader implements html reference images, adds version numbers and implements template functions.

}According to the directory correspondence, obtain the html entry corresponding to js
let entryHtml = getEntryHtml('./src/view/**/*.html'),
configPlugins;
entryHtml.forEach(function (v) {
configPlugins.push(new HtmlWebpackPlugin(v));
});
// webpack 配置
resolve: {
alias: {
views: path.resolve(ROOT, './src/view')
}
},
/**

function getEntryHtml (globPath) {
let entries = [];
Glob.sync(globPath).forEach(function (entry) {
let basename = path.basename(entry, path.extname(entry)),
pathname = path.dirname(entry),
// @see
minifyConfig = IsDev ? '' : {
removeComments: true,
collapseWhitespace: true,
minifyCSS: true,
minifyJS: true
};
entries.push({
filename: entry.split('/').splice(2).join('/'),
template: entry,
chunks: ['common', pathname.split('/').splice(3).join('/') + '/' + basename],
minify: minifyConfig
});
});
return entries;
}Use happypack multi-threading to speed up the build, CommonsChunkPlugin implements extraction of public js into separate files, extract-text-webpack-plugin implements extraction of public css into separate files,
let configPlugins = [
new HappyPack({
id: 'js',
// @see
threadPool: HappyThreadPool,
loaders: ['babel-loader']
}),
new HappyPack({
id: 'styles',
threadPool: HappyThreadPool,
loaders: ['style-loader', 'css-loader', 'less-loader', 'postcss-loader']
}),
new webpack.optimize.CommonsChunkPlugin({
name: 'common'
}),
// @see
new ExtractTextPlugin({
filename: 'css/[name].css?[contenthash:8]',
allChunks: true
})
];
entryHtml.forEach(function (v) {
configPlugins.push(new HtmlWebpackPlugin(v));
});
// webpack 配置
plugins: configPlugins,webpack-dev-server implements functions such as automatic refresh of the development environment
// webpack 配置

contentBase: [
