A handy guide on setting up webpack 5.x to automatically clear the dist folder before starting the build process

Prior to the next build, I am considering removing the previous build. If we do not delete the old build, any changes that did not result in an output file may go unnoticed for a while. Currently, I am attempting to achieve this using the following command in the package.json:

"dev": "rm -rf src/bundle && webpack --mode development --config build/webpack.dev.config.js"

However, I have some concerns about the safety of using the rm -rf command. Does anyone have a better suggestion?

Answer №1

For more information, be sure to visit the official documentation: https://webpack.js.org/guides/output-management/#cleaning-up-the-dist-folder

To implement this feature, simply include clean:true

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
entry: {
  index: './src/index.js',
  print: './src/print.js',
},
plugins: [
  new HtmlWebpackPlugin({
    title: 'Output Management',
  }),
],
output: {
  filename: '[name].bundle.js',
  path: path.resolve(__dirname, 'dist'),
  clean: true
},

};

Answer №2

My solution to the issue is outlined below:

  plugins: [
    new HtmlWebpackPlugin({
       template: path.join(__dirname, 'src', 'template.pug'),
       filename: 'index.html', 
    }),
    new FileManagerPlugin({
        events: {
          onStart: { 
             delete: [
              {
                source: path.join(__dirname,'dist/').replaceAll('\\','/'), 
                 options:{
                   force: true,
                   recursive : true,
                   },
               },
             ],
           },
        },
     })

In order for webpack to properly recognize the complete file path, it is necessary to define the full path and replace all instances of \ with /.
