webpack配置
let path = require('path');
let htmlWebpackPlugin = require('html-webpack-plugin');
const webpack = require('webpack');
const CleanWebpackPlugin = require('clean-webpack-plugin');
module.exports = {
entry: './main.js',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'bundle.js'
},
mode: 'development',
devtool: 'inline-source-map',
devServer: {
contentBase: './dist',
hot: true
},
plugins: [
new htmlWebpackPlugin(),
new CleanWebpackPlugin(['dist']),
new webpack.NamedModulesPlugin(),
new webpack.HotModuleReplacementPlugin()
]
}
一切都是安装文档配置,结果报了个错: [HMR] Hot Module Replacement is disabled.
查了stackoverflow,需要在启动的时候加上下面这一句
--hot --inline
package.json配置如下:
"start": "webpack-dev-server --hot --inline --open"
