How to transform Vue-cli into a history mode that supports multiple pages

This article mainly introduces in detail how to transform Vue-cli into a history mode that supports multiple pages. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.

The title description may not be accurate, but this is probably the requirement:

Use Vue-cli to build a multi-entry, multi-page site, that is, through the html-webpack-plugin plug-in Multiple .html files will be generated. By default, only the index.html entry can use history mode, such as: http://www.xxx.com/xxx/xxx, while other entries can only use hash mode. For example: http://www.xxx.com/admin.html#/xxx/xxx, because webpack-dev-middleware will point all routes to the index.html file, if it is online, history mode is required. This will cause some trouble.

It’s so stupid. Just after I finished writing the article, I discovered that the connect-history-api-fallback plug-in does this...

Method update As follows:

Modify the build/dev-server.js file

app.use(require('connect-history-api-fallback')())

to

var history = require('connect-history-api-fallback')
app.use(history({
  rewrites: [
    { from: 'index', to: '/index.html'}, // 默认入口
    { from: /\/backend/, to: '/backend.html'}, // 其他入口
    { from: /^\/backend\/.*$/, to: '/backend.html'},
  ]
}))

Please refer to the specific rules: https://github.com/bripkens/connect-history-api-fallback

-------------- Please ignore the following code--- -----------

Let's make some changes so that all entries support history mode:

1. First, we create a setup in the build directory -dev-server.js file, the code inside is as follows:

const path = require('path')
const webpack = require('webpack')
const clientConfig = require('./webpack.dev.conf') // 引入开发环境下的 webpack 配置文件

module.exports = function setupDevServer(app, opts) {
  const clientCompiler = webpack(clientConfig)
  // 加载 webpack-dev-middleware 插件
  const devMiddleware = require('webpack-dev-middleware')(clientCompiler, {
    publicPath: clientConfig.output.publicPath,
    stats: {
      colors: true,
      chunks: false
    }
  })
  app.use(devMiddleware)
  // 关键代码开始
  // 因为开发环境下, 所有的文件都在内存里, 包括由 html-webpack-plugin 生成的 .html 文件, 所以我们需要用 webpack-dev-middleware 提供的 api 从内存里读取
  clientCompiler.plugin('done', () => {
    const fs = devMiddleware.fileSystem // 访问内存
    const filePath = path.join(clientConfig.output.path, 'index.html') // 读取的文件, 文件名和 html-webpack-plugin 生成的文件名要求一致
    if (fs.existsSync(filePath)) { // 判断下文件是否存在
      const index = fs.readFileSync(filePath, 'utf-8') // 从内存里取出
      opts.indexUpdated(index) // 将取出的文件通过 indexUpdated 函数返回, 这个函数怎么来的, 后面会说明
    }
    const adminPath = path.join(clientConfig.output.path, 'backend.html') // 同上, 这是第二个入口生成的 .html 文件, 如果还有其他入口, 这个多复制几份
    if (fs.existsSync(adminPath)) {
      const admin = fs.readFileSync(adminPath, 'utf-8')
      opts.adminUpdated(admin)
    }
  })

  // 加载热重载模块
  app.use(require('webpack-hot-middleware')(clientCompiler))
  var hotMiddleware = require('webpack-hot-middleware')(clientCompiler)
  // 当修改 html-webpack-plugin 模版时, 自动刷新整个页面
  clientCompiler.plugin('compilation', function(compilation) {
    compilation.plugin('html-webpack-plugin-after-emit', function(data, cb) {
      hotMiddleware.publish({
        action: 'reload'
      })
      cb()
    })
  })
}

2. Modify the build/dev-server.js file

Mainly modify the var in the file The code between app = express() to module.exports = app.listen(port, function (err) {

var app = express()

var indexHTML
var adminHTML

// 引用前面创建的文件, 并将两个保存内容的函数传过去, 这里保存内容的变量写成对象或者数组也可以, 还可以少点代码
require('../config/setup-dev-server')(app, {
  indexUpdated: index => {
    indexHTML = index
  },
  adminUpdated: index => {
    adminHTML = index
  },
})

// 加载反向代理
Object.keys(proxyTable).forEach(function(context) {
  var options = proxyTable[context]
  if (typeof options === 'string') {
    options = {
      target: options
    }
  }
  app.use(proxyMiddleware(context, options))
})
// 设置静态文件夹路由
var staticPath = path.posix.join(config.assetsPublicPath, config.assetsSubDirectory)
app.use(staticPath, express.static('./static'))

// 入口1路由
app.get(['/', '/category/:id'], (req, res) => {
  res.send(indexHTML)
})

// 入口2路由
app.get(['/backend', '/backend/*'], (req, res) => {
  res.send(adminHTML)
})

// 404 页面
app.get('*', (req, res) => {
  res.send('HTTP STATUS: 404')
})

app.use(function(req, res, next) {
  var err = new Error('Not Found')
  err.status = 404
  next(err)
})

app.use(function(err, req, res) {
  res.status(err.status || 500)
  res.send(err.message)
})

module.exports = app.listen(port, function(err) {

3. npm run dev and start writing happily Code Bar
