webpack dev服务器端口

Question

我需要更改哪个端口webpack-dev-server听。

到目前为止，我已经创建了这些文件：

• webpack.common.js
• webpack.dev.js
• webpack.prod.js

如果你还没有创建一个package.json文件，那么如果你创建一个并且有这样的代码块就会很好：

 $('#select1').on('change',function(){
        if ($('#select1').val() == 'Red') {
            $('#elements .anElement').hide().filter('[color*="'Red' "]').show();
 }
 ...  

您可以删除未使用的模块。 然后运行：{ "name": "someName", "description": "description", "main": "index.js", "scripts": { "start": "webpack-dev-server --host 0.0.0.0 --port 8080 --devtool eval --progress --colors", "build": "NODE_ENV=production webpack --config webpack.config.prod.js -p" }, "dependencies": { "babel-polyfill": "^6.16.0", "html-webpack-plugin": "^2.24.1", "react": "^15.3.2", "react-dom": "^15.3.2", "react-router": "^3.0.0", "redux": "^3.6.0" }, "devDependencies": { "babel-core": "^6.17.0", "babel-loader": "^6.2.5", "babel-preset-es2015": "^6.16.0", "babel-preset-react": "^6.16.0", "webpack": "^1.13.2", "webpack-dev-server": "^1.16.2" }, "babel": { "presets": [ "es2015", "react" ], "plugins": [ "transform-runtime", "transform-object-rest-spread" ] } } 它将在端口8080上运行

如果在没有package.json的情况下启动dev服务器。 您可以直接从终端运行以下内容。

npm start
