import merge from "webpack-merge"
import webpack from "webpack"
import webpackDevServer from "webpack-dev-server"
import { format } from 'util'
let PORT = 1699;
let PUBLIC_PATH = "http://localhost:" + PORT + "/";
let webpackConifg = merge(config, {
devtool: "source-map",
//debug: true, webpack2 已切换到plugins中，据说在3中将取消
entry: {
main: [
format("webpack-dev-server/client?%s", PUBLIC_PATH),
"webpack/hot/dev-server",
"./src/main.ts"
]
},
output: {
path: path.resolve(__dirname, '../../dist'),
publicPath: PUBLIC_PATH,
filename: '[name].js'
},
plugins: [
new webpack.HotModuleReplacementPlugin()
]
})
const compiler = webpack(webpackConifg);
new webpackDevServer(compiler, {
inline: true,
hot: true,
port: PORT,
stats: {
colors: true
}
}).listen(PORT, 'localhost', (err) => {
console.log(123)
