tsconfig-paths-webpack-plugin 4.0.1

The tsconfig-paths-webpack-plugin is a potent tool for developers working with TypeScript and Webpack. Its primary function is to load modules whose location is specified in the paths section of tsconfig.json when using Webpack. In other words, it serves as a Webpack plugin that offers the functionality provided by the tsconfig-paths package. This eliminates the need to add alias entries in the webpack.config.js file that match the paths in your tsconfig.json, as the plugin automatically generates these alias entries for you.

To utilize the tsconfig-paths-webpack-plugin, developers need to follow specific steps. Initially, it has to be installed. This can be done via yarn using yarn add --dev tsconfig-paths-webpack-plugin or through npm by typing npm install --save-dev tsconfig-paths-webpack-plugin.

Secondly, in the Webpack configuration file, you need to add the plugin:

const TsconfigPathsPlugin = require('tsconfig-paths-webpack-plugin');

module.exports = {
  ...
  resolve: {
    plugins: [new TsconfigPathsPlugin({/* options: see below */})]
  }
  ...
}

Please note that the plugin must be placed in the resolve.plugins section of the configuration. Also, if you're using the allowJs in tsconfig.json or allowing other non-TS extensions in Webpack, ensure you set the extensions option in sync with your Webpack config. Various other options provide customization and better functionality control.

The detailed documentation for the tsconfig-paths-webpack-plugin can be found within its repository on GitHub. The README file from the repo provides comprehensive information about installation steps, usage, options available for configuration, instructions for testing, TypeScript support, and more. The URL is https://github.com/dividab/tsconfig-paths-webpack-plugin. It is worth noting that the package comes with TypeScript typings for added convenience when working with TypeScript within the Webpack config.
