How to solve the problem of vuejs not having dev? The latest vue does not have a dev-server.js file. How to simulate background data?
In the latest vue, dev-server.js has been replaced by webpack-dev-conf.js
When simulating background data, modify it directly in the webpack-dev-conf.js file
The first step is to add
//第一步 const express = require('express') const app = express()//请求server var appData = require('../data.json')//加载本地数据文件 var seller = appData.seller//获取对应的本地数据 var goods = appData.goods var ratings = appData.ratings var apiRoutes = express.Router() app.use('/api', apiRoutes)//通过路由请求数据
after const portfinder = require('portfinder'). The second step is to find the devServer and add the before() method in it
devServer: { clientLogLevel: 'warning', historyApiFallback: true, hot: true, 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, }, //第二步找到devServer,在里面添加 before(app) { app.get('/api/seller', (req, res) => { res.json({ errno: 0, data: seller })//接口返回json数据,上面配置的数据seller就赋值给data请求后调用 }), app.get('/api/goods', (req, res) => { res.json({ errno: 0, data: goods }) }), app.get('/api/ratings', (req, res) => { res.json({ errno: 0, data: ratings }) }) } }
Provide a json.data data
