vue-cli到多页应用
前言：我有一个cli创建的vue项目，但是我想做成多页应用，怎么办，废话不多说，直接开撸~
约定：新增代码部分在//add和//end中间 删除(注释)代码部分在//del和//end中间，很多东西都写在注释里
第一步：cli一个vue项目
新建一个vue项目 官网 vue init webpack demo
cli默认使用webpack的dev-server服务，这个服务是做不了单页的，需要手动建一个私服叫啥你随意 一般叫dev.server或者dev.client
第二步：添加两个方法处理出口入口文件（SPA默认写死的）
进入刚刚创建vue项目 cd demo
在目录下面找到build/utils.js文件
修改部分：
utils.js
'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~
