Webpack procedure 1

The examples are based on Webpack 5

• Based on How to configure Webpack 4 or 5 from scratch for a basic website

$ npm i --save-dev webpack webpack-cli

• It installs webpack with webpack cli
• But the best step is on webpack process 2
• Create a webpack.config.js in the root folder
• Give the entry point of your index.js in the webpack.comfig.js file example entry: "./src/index.js",
• Make the watch true in the webpack.comfig.js file to let the webpack watching the files
• Install babel loader. Installing command npm install -D babel-loader @babel/core @babel/preset-env webpack.
• Install Sass loader for compiling sass npm install sass-loader sass webpack --save-dev
• Keep your index.html inside dist folder to work with auto reload by browserSynck plugin, else it will not work. Reason base directory is server: { baseDir: ["dist"] }
• Additional Plugins used here
  • BrowserSync Webpack
  • Webpack watch external files

• Run the build with npm run build

Treat index.js as entry points for all your component scripts and styles. Use:

• import { NumberTxt, Maintxt } from "./components/number" if js files
