手把手教你vue-cli单页到多页应用的方法

'use strict'
const path = require('path')
const config = require('../config')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const packageConfig = require('../package.json')

//add
const glob = require('glob');
const HtmlWebpackPlugin = require('html-webpack-plugin');  //功能：生成html文件及js文件并把js引入html
const pagePath = path.resolve(__dirname, '../src/views/'); //页面的路径，比如这里我用的views，那么后面私服加入的文件监控器就会从src下面的views下面开始监控文件
//end

exports.assetsPath = function (_path) {
 const assetsSubDirectory = process.env.NODE_ENV === 'production'
  "text-align: left">第三步：创建私服（不使用dev-server服务，自己建一个）

从express新建私服并配置(build文件夹下新建 我这里叫webpack.dev.client.js)
webpack.dev.client.js


/**
 * created by qbyu2 on 2018-05-30
 * express 私服
 * */
'use strict';

const fs = require('fs');
const path = require('path');
const express = require('express');
const webpack = require('webpack');
const webpackDevMiddleware = require('webpack-dev-middleware');  //文件监控(前面配置了从views下面监控)
const webpackHotMiddleware = require('webpack-hot-middleware');  //热加载
const config = require('../config');
const devWebpackConfig = require('./webpack.dev.conf');
const proxyMiddleware = require('http-proxy-middleware');  //跨域

const proxyTable = config.dev.proxyTable;

const PORT = config.dev.port;
const HOST = config.dev.host;
const assetsRoot = config.dev.assetsRoot;
const app = express();
const router = express.Router();
const compiler = webpack(devWebpackConfig);

let devMiddleware = webpackDevMiddleware(compiler, {
 publicPath: devWebpackConfig.output.publicPath,
 quiet: true,
 stats: {
  colors: true,
  chunks: false
 }
});

let hotMiddleware = webpackHotMiddleware(compiler, {
 path: '/__webpack_hmr',
 heartbeat: 2000
});

app.use(hotMiddleware);
app.use(devMiddleware);

Object.keys(proxyTable).forEach(function (context) {
 let options = proxyTable[context];
 if (typeof options === 'string') {
  options = {
   target: options
  };
 }
 app.use(proxyMiddleware(context, options));
});

//双路由  私服一层控制私服路由  vue的路由控制该页面下的路由
app.use(router)
app.use('/static', express.static(path.join(assetsRoot, 'static')));

let sendFile = (viewname, response, next) => {
 compiler.outputFileSystem.readFile(viewname, (err, result) => {
  if (err) {
   return (next(err));
  }
  response.set('content-type', 'text/html');
  response.send(result);
  response.end();
 });
};

//拼接方法
function pathJoin(patz) {
 return path.join(assetsRoot, patz);
}

/**
 * 定义路由(私服路由 非vue路由)
 * */

// favicon
router.get('/favicon.ico', (req, res, next) => {
 res.end();
});

// http://localhost:8080/
router.get('/', (req, res, next)=>{
 sendFile(pathJoin('index.html'), res, next);
});

// http://localhost:8080/home
router.get('/:home', (req, res, next) => {
 sendFile(pathJoin(req.params.home + '.html'), res, next);
});

// http://localhost:8080/index
router.get('/:index', (req, res, next) => {
 sendFile(pathJoin(req.params.index + '.html'), res, next);
});

module.exports = app.listen(PORT, err => {
 if (err){
  return
 }
 console.log(`Listening at http://${HOST}:${PORT}\n`);
})


私服创建好了 安装下依赖


有坑。。。


webpack和热加载版本太高太低都不行




npm install webpack@3.10.0 --save-dev
npm install webpack-dev-middleware --save-dev
npm install webpack-hot-middleware@2.21.0 --save-dev
npm install http-proxy-middleware --save-dev


第四步：修改配置webpack.base.conf.js


'use strict'
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const path = require('path')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const FriendlyErrorsPlugin = require('friendly-errors-webpack-plugin')
const portfinder = require('portfinder')

const HOST = process.env.HOST
const PORT = process.env.PORT && Number(process.env.PORT)

const devWebpackConfig = merge(baseWebpackConfig, {
 module: {
  rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap, usePostCSS: true })
 },
 // cheap-module-eval-source-map is faster for development
 devtool: config.dev.devtool,

 // these devServer options should be customized in /config/index.js
 devServer: {
  clientLogLevel: 'warning',
  historyApiFallback: {
   rewrites: [
    { from: /.*/, to: path.posix.join(config.dev.assetsPublicPath, 'index.html') },
   ],
  },
  hot: true,
  contentBase: false, // since we use CopyWebpackPlugin.
  compress: true,
  host: HOST || config.dev.host,
  port: PORT || config.dev.port,
  open: config.dev.autoOpenBrowser,
  overlay: config.dev.errorOverlay
   "htmlcode">

'use strict'
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const path = require('path')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const FriendlyErrorsPlugin = require('friendly-errors-webpack-plugin')
const portfinder = require('portfinder')

const HOST = process.env.HOST
const PORT = process.env.PORT && Number(process.env.PORT)

const devWebpackConfig = merge(baseWebpackConfig, {
 module: {
  rules: utils.styleLoaders({ sourceMap: config.dev.cssSourceMap, usePostCSS: true })
 },
 // cheap-module-eval-source-map is faster for development
 devtool: config.dev.devtool,

 // these devServer options should be customized in /config/index.js
 //del 注掉SPA的服务器
 // devServer: {
 //  clientLogLevel: 'warning',
 //  historyApiFallback: {
 //   rewrites: [
 //    { from: /.*/, to: path.posix.join(config.dev.assetsPublicPath, 'index.html') },
 //   ],
 //  },
 //  hot: true,
 //  contentBase: false, // since we use CopyWebpackPlugin.
 //  compress: true,
 //  host: HOST || config.dev.host,
 //  port: PORT || config.dev.port,
 //  open: config.dev.autoOpenBrowser,
 //  overlay: config.dev.errorOverlay
 //   "color: #ff0000">第五步：修改package.json 指令配置

scripts下面'dev':


这样执行的时候就不会走默认的dev-server而走你的私服了


"scripts": {
  "dev": "node build/webpack.dev.client.js",
  "start": "npm run dev",
  "build": "node build/build.js"
 },


第六步：创建测试文件
src目录下新建 views文件夹 （代码注释里有 当时配的目录跟这个一致就可以 随便你命名 遵循命名规范就行）

views 文件夹下新建两个文件夹index和home 代表多页 每页单独一个文件夹 文件夹下建对应文件

最后，npm run dev
这个时候你会发现，特么的什么鬼文章 报错了啊


稍安勿躁~


两个地方，
1.webpack.dev.client.js


//双路由  私服一层控制私服路由  vue的路由控制该页面下的路由
app.use(router)
app.use('/static', express.static(path.join(assetsRoot, 'static')));


这个assetsRoot cli创建的时候是没有的 在config/index.js 下面找到dev加上


assetsRoot: path.resolve(__dirname, '../dist'),





顺便把dev和build的assetsPublicPath 路径都改成相对路径'./'
2.还是版本问题
webpack-dev-middleware 默认是3.1.3版本但是会报错


具体哪个版本不报错我也不知道


context.compiler.hooks.invalid.tap('WebpackDevMiddleware', invalid);


找不到invalid 源码里面是有的


卸载webpack-dev-middleware


npm uninstall webpack-dev-middleware


使用dev-server自带的webpack-dev-middleware （cli单页应用是有热加载的）


重新install dev-server


npm install webpack-dev-server@2.10.0 --save-dev




npm run dev




总结：核心点就在创建并配置私服和修改出口入口配置，坑就在版本不兼容
建议：cli一个vue的demo项目 从头撸一遍 再在实际项目里使用，而不是copy一下运行没问题搞定~


建议而已，你怎么打人，呜呜呜~
