Nodejs:简单的脚手架(一)
html-webpack-plugin: 用来生成html文件的插件
glob: 用来筛选文件,文件目录
path: 管理文件路径
次脚手架里主要用到的是这3个插件,后续会根据所用插件逐渐完善脚手架:
entry部分:定义一个glob对象,在pages目录下面搜寻页面路径(index/index;login/index),路径按照此规范写,方便后面组织管理,一个小模块为一个页面,具体glob对象的使用方法前面有介绍。
plugins部分:引入了jquery,同时提取了公共样式。每个模板返回的ejs都在HtmlWebpackPlugin里生成了html文件并输出,这里用到了箭头函数,es6的,注意js文件需要用bable处理一下。
loaders:都是一些常用通用的,我个人的理解为对不同后缀的文件进行不同的处理,大同小异。
alias:自己定义require的路径,当一些组件引用频繁的时候,可以放在这里面便于处理。
文件目录如下:
--src |--pages | |--index | | |--index | | |--page.ejs | | |--html.js | | |--page.js | | |--page.less | |--lgoin | |--..同上 |-public....
脚手架代码如下:
var webpack = require('webpack'); var glob = require('glob'); var path = require('path'); var precss = require('precss'); var autoprefixer = require('autoprefixer'); var ExtractTextPlugin = require('extract-text-webpack-plugin'); var HtmlWebpackPlugin = require('html-webpack-plugin'); var publicDir = path.resolve(__dirname, './src') var pagesDir = path.resolve(__dirname, './src/pages') var staticDir = path.resolve(__dirname, './src/static') var buildDir = path.resolve(__dirname, './build') /* * entry */ var pageEntry = {}; var globInstance = new glob.Glob('!(_)*/!(_)*', { cwd: pagesDir, sync: true, }); var pageArr = globInstance.found; pageArr.forEach((page) => { pageEntry[page] = path.resolve(pagesDir, page + '/page'); }); /* * plugins */ var configPlugins = [ new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery', 'window.jQuery': 'jquery', 'window.$': 'jquery', }), new webpack.optimize.CommonsChunkPlugin({ name: 'commons/commons', minChunks: 2, }), new ExtractTextPlugin("[name]/styles.css") ]; /* * plugins - for ejs page * page --> login/index */ pageArr.forEach((page) => { const htmlPlugin = new HtmlWebpackPlugin({ filename: `${page}/page.html`, template: path.resolve(pagesDir, `./${page}/html.js`), chunks: [page, 'commons/commons'], hash: true, xhtml: true, }); configPlugins.push(htmlPlugin); }); module.exports = { entry: pageEntry, output:{ path: buildDir, filename: '[name]/entry.js' }, module:{ loaders: [ { test: /\.css$/, exclude: /node_modules|bootstrap/, loader: ExtractTextPlugin.extract('css?minimize&-autoprefixer!postcss'), }, { test: /\.less$/, include: publicDir, loader: ExtractTextPlugin.extract('css?minimize&-autoprefixer!postcss!less'), }, { test: /\.js$/, include: publicDir, loader: 'babel-loader?presets[]=es2015-loose&cacheDirectory&plugins[]=transform-runtime', }, { test: /\.html$/, include: publicDir, loader: 'html', }, { test: /\.ejs$/, include: publicDir, loader: 'ejs', }, { test: /\.(png|jpg|gif)$/, include: publicDir, loader: 'url?limit=8192&name=./static/img/[hash].[ext]', }, { test: /\.(woff|woff2|svg|eot|ttf)\??.*$/, include: publicDir, loader: 'file?name=static/fonts/[name].[ext]', }] }, plugins: configPlugins, resolve:{ alias: { layout: path.resolve(publicDir, 'public-resource/layout'), public: path.resolve(publicDir, 'public-resource/public'), wrapURL:path.resolve(publicDir, 'public-resource/libs/constructInsideUrl.js'), }, extentions: ['', 'js'], } };
