webpack实现css和js文件的hash解决缓存问题

前期库安装:

package.json

{

"name": "web-cat",
"version": "1.0.0",
"description": "在线word翻译",
"main": "index.js",
"scripts": {
"start": "webpack-dev-server"
},
"dependencies": {
"babel-core": "^6.18.2",
"babel-loader": "^6.2.8",
"babel-preset-es2015": "^6.18.0",
"jquery": "^3.1.1"
},
"devDependencies": {
"css-loader": "^0.28.1",
"ejs-loader": "^0.3.0",
"extract-text-webpack-plugin": "^1.0.1",
"file-loader": "^0.11.1",
"html-webpack-plugin": "^2.28.0",
"style-loader": "^0.17.0",
"url-loader": "^0.5.8",
"webpack-dev-server": "^1.16.2"
}
}
2.webpack.config.js
var webpack = require("webpack");
var HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
entry : __dirname + "/dev/main.js",
output : {
path : __dirname + "/out",
filename : "index.js"
},
module:{
loaders :[{ test: /\.ejs$/, loader: "ejs-loader?variable=data" },
{ test: /\.css$/, loader: ExtractTextPlugin.extract("style-loader","css-loader")},
{test: /\.(jpg|jpeg|gif|png)$/,loader: 'url?limit=8000&name=imgs/[name].[ext]'},
]
},
plugins: [new HtmlWebpackPlugin({
filename: __dirname + '/index.html',
template: __dirname + '/template.ejs',
hash : true,
inject : true,
}),
new ExtractTextPlugin("style.css"),
]
3.main.js
require("../css/style.css")

4.最后打包的css和js文件就会自动引入到html中去，并且带上hash值。
