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
