webpack + koa 一只报等待打包 wait until bundle finished:

Question

require('babel-register')
const express = require('express')
const webpack = require('webpack')
const webpackConfig = require('./webpack.config')

const app = express()

// webpack编译器
var compiler = webpack(webpackConfig);

// webpack-dev-server中间件
var devMiddleware = require('webpack-dev-middleware')(compiler, {
    publicPath: webpackConfig.output.publicPath,
    stats: {
        colors: true,
        chunks: false
    }
});

app.use(devMiddleware)

// 路由
app.get('/:viewname?', function(req, res, next) {

    var viewname = req.params.viewname ? req.params.viewname + '.html' : 'index.html';

    var filepath = path.join(compiler.outputPath, viewname);

    // 使用webpack提供的outputFileSystem
    compiler.outputFileSystem.readFile(filepath, function(err, result) {
        if (err) {
            // something error
            return next(err);
        }
        console.log(22222, result)
        res.set('content-type', 'text/html');
        res.send(result);
        res.end();
    });
});

module.exports = app.listen(3000)
