webpack.dev.conf.js中添加两段代码
'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') //首先 const express = require('express') const app = express() var appData = require('../data.json') var seller = appData.seller var goods = appData.goods var ratings = appData.ratings var apiRoutes = express.Router() app.use('/api', apiRoutes) 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 ? { warnings: false, errors: true } : false, publicPath: config.dev.assetsPublicPath, proxy: config.dev.proxyTable, quiet: true, // necessary for FriendlyErrorsPlugin watchOptions: { poll: config.dev.poll, }, before(app) { app.get('/api/seller', (req, res) => { res.json({ // 这里是你的json内容 errno: 0, data: seller }) }), app.get('/api/goods', (req, res) => { res.json({ // 这里是你的json内容 errno: 0, data: goods }) }), app.get('/api/ratings', (req, res) => { res.json({ // 这里是你的json内容 errno: 0, data: ratings }) }) } }, plugins: [ new webpack.DefinePlugin({ 'process.env': require('../config/dev.env') }), new webpack.HotModuleReplacementPlugin(), new webpack.NamedModulesPlugin(), // HMR shows correct file names in console on update. new webpack.NoEmitOnErrorsPlugin(), // https://github.com/ampedandwired/html-webpack-plugin new HtmlWebpackPlugin({ filename: 'index.html', template: 'index.html', inject: true }), // copy custom static assets new CopyWebpackPlugin([ { from: path.resolve(__dirname, '../static'), to: config.dev.assetsSubDirectory, ignore: ['.*'] } ]) ] }) module.exports = new Promise((resolve, reject) => { portfinder.basePort = process.env.PORT || config.dev.port portfinder.getPort((err, port) => { if (err) { reject(err) } else { // publish the new Port, necessary for e2e tests process.env.PORT = port // add port to devServer config devWebpackConfig.devServer.port = port // Add FriendlyErrorsPlugin devWebpackConfig.plugins.push(new FriendlyErrorsPlugin({ compilationSuccessInfo: { messages: [`Your application is running here: http://${devWebpackConfig.devServer.host}:${port}`], }, onErrors: config.dev.notifyOnErrors ? utils.createNotifierCallback() : undefined })) resolve(devWebpackConfig) } }) })
添加Header.vue
<template> <div class="header"> 我是header </div> </template> <script> export default { name: 'header.vue' } </script> <style scoped> </style>
App.vue
<template> <div id="app"> <v-header></v-header> <div class="tab"> I am tab </div> <img src="./assets/logo.png"> <router-view/> </div> </template> <script> import VHeader from './components/header/header.vue' export default { components: { VHeader } } </script> <style> #app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px; } </style>
VHeader是系统推荐的写法。
运行结果
