How to add a js file with webpack?

阅读更多关于 How to add a js file with webpack?

问题 I was reading this webpack tutorial: https://webpack.github.io/docs/usage.html It says it bundles the src files and node_modules. If I want to add another .js file there, how can I do this? This is a thirdpartyjs file that is not part of the source and not part of the node_modules files. This is my current webpack.config.js: var path = require('path'); var webpack = require('webpack'); module.exports = { entry: [ 'react-hot-loader/patch', 'webpack-dev-server/client?http://localhost:8080',

webpack5都出了，webpack4的的基本配置，解析ES6，引入CSS，编译Less，设置image等等，你都会了么？解析ES6 了解Babel Babel是一个JavaScript编译器，可以实现将ES6+转换成浏览器能够识别的代码。 Babel在执行编译时，可以依赖.babelrc文件，当设置依赖文件时，会从项目的根目录下读取 .babelrc 的配置项，.babelrc配置文件主要是对预设(presets) 和插件(plugins) 进行配置。其中，presets可以标识需要转换的源码使用了哪些新特性，可以理解为一系列plugins的集合，例如babel-preset-es2015，可以将es6转换为es5；而plugins则指示babel如何对代码进行转换，例如plugin-transform-arrow-functions可将ES6语法转换为 ES5。解析ES6 1、安装依赖 npm i @babel/core @babel/preset-env babel-loader -D 2、配置webpack.config.js设置loader module: { rules: [ { test: /.js$/, use: 'babel-loader' } ] } 3、根目录创建.babelrc，并配置preset-env对ES6+语法特性进行转换

Using a simple vue.js/webpack setup, how does one configure the dev server to proxy everything EXCEPT a few .js and .vue files?

问题 So some quick background on the site's current setup: My company's site currently runs off of a CMS. All pages are generated and routed via the CMS, so there are no .html files anywhere. It's all generated via razor (.cshtml), the CMS as a backend/data-store, and routing is handled through the CMS. If it were up to me I'd rewrite the entire thing, but I don't have that luxury. I'm doing my best to rewrite the site with a Vue.js + webpack front-end wherever possible and slowly rebuild this

问题 I think the problem is not with react router configuration but my index.html not being able to detect my script? This is my error: Failed to load resource: the server responded with a status of 404 (Not Found) this is my webpack config code: const compiler = webpack({ entry: ['whatwg-fetch', path.resolve(__dirname, 'js', 'index.js')], module: { loaders: [ { exclude: /node_modules/, loader: 'babel-loader', test: /\.js$/, }, { test: /\.css$/, loaders: ['style-loader', 'css-loader'] } ], },

1. 介绍在开发react应用时，应该没有人用传统的方法引入react的源文件(js)，然后在html编辑吧。大家都是用webpack + es6来结合react开发前端应用。这个时候，我们可以手动使用npm来安装各种插件，来从头到尾自己搭建环境。比如： npm install react react-dom --save npm install babel babel-loader babel-core babel-preset-es2015 babel-preset-react --save npm install babel webpack webpack-dev-server -g 复制代码虽然自己搭建的过程也是一个很好的学习过程，但是有时候难免遇到各种问题，特别是初学者，而且每次开发一个新应用，都要自己从头搭建，未免太繁琐。于是，有人根据自己的经验和最佳实践，开发了脚手架，避免开发过程中的重复造轮子和做无用功，从而节省开发时间。类似这样的脚手架，我扫了网络上比较多人用和关注的，一共发现了三个，它们分别是： react-boilerplate react-redux-starter-kit create-react-app 它们的关注量都非常大，截至写这篇文章为止，在github上的star量是这样的：由此可见，使用这三个脚手架的人都相当多，最突出的是

问题 I am trying to implement Material Web Components into my Web App as per Material Component Web's Getting Started Guide. I was able to successfully set up Webpack (V3) to load the SASS for a web component. This was after running into a problem with the include path. I was able to resolve this by adding this line to my webpack.config.js . { loader: 'sass-loader', options: { includePaths: ['./node_modules'] } } However, I wasn't as successful compiling the JS. The component in question is
