webpack 图片的打包

news 来源：原创 2024/5/3 8:32:36

1. 在img文件夹下随便找一个小一点的图片放进去.

2.修改entry.js

require('../css/index.css');

var demo1 = require('../js/demo1.js');
var demo2 = require('../js/demo2.js');

    demo1.init();
    demo2.init();

var oImg = new Image();
oImg.src = require('../img/1.gif');//当成模块引入图片
document.body.appendChild(oImg);

由于我们引入的是静态资源, 在webpack.config.js中修改一下

module.exports = {
        entry :  './src/js/entry.js',
        output : {
            filename : 'index.js',
            publicPath: __dirname + '/out',//添加静态资源, 否则会出现路径错误
            path : __dirname + '/out'
        },
        module : {
            rules: [
                {test: /.js$/, use: ['babel-loader']},
                {test: /.css$/, use: ['style-loader', 'css-loader']},/*解析css, 并把css添加到html的style标签里*/
                //{test: /.css$/, use: ExtractTextPlugin.extract({fallback: 'style-loader',use: 'css-loader'})},/*解析css, 并把css变成文件通过link标签引入*/
                {test: /.(jpg|png|gif|svg)$/, use: ['url-loader?limit=8192&name=./[name].[ext]']},/*解析图片*/
                {test: /.less$/, use: ['style-loader', 'css-loader', 'less-loader']}/*解析less, 把less解析成浏览器可以识别的css语言*/
            ]
        },
}

自己webpack看看效果

webpack服务器

首先先定位目录输入命令 npm install webpack-dev-server -g , 修改webpack.config.js文件

publicPath: 'http://localhost:8080/out',

html文件所引用的目录也要更改:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" />
    <title>text</title>
     <link rel="stylesheet" href="http://localhost:8080/out/index.css">
</head>
<body>
    <a href="http://localhost:8080/index2.html">11</a>
    <div class="demo1"></div>
    <div class="demo2"></div>
    <script src="http://localhost:8080/out/common.js"></script>
    <script src="http://localhost:8080/out/index.js"></script>
</body>
</html>
