How to use the SourceMapDevToolPlugin function from webpack

webpack.SourceMapDevToolPlugin is a plugin that generates source maps for JavaScript files, allowing for easier debugging of the original code in the browser's developer tools.

How does webpack.SourceMapDevToolPlugin work?

webpack.SourceMapDevToolPlugin is a plugin for the Webpack module bundler that generates source maps for JavaScript files. Source maps are files that provide a mapping between the compiled JavaScript code and the original source code, allowing for easier debugging of the original code in the browser's developer tools.

To use the plugin, you simply add an instance of it to your Webpack configuration file as a plugin, like this:

javascriptCopy code
const webpack = require('webpack');

module.exports = {
  // other configuration options...
  devtool: 'source-map',
  plugins: [
    new webpack.SourceMapDevToolPlugin({})
  ]
};

In this example, we are creating an instance of webpack.SourceMapDevToolPlugin and adding it to the plugins array in our Webpack configuration file.

We also set the devtool option to source-map, which tells Webpack to generate source maps for our JavaScript files.

Now, when we run the Webpack build process, the plugin will generate source maps for our JavaScript files. These source maps will be saved as separate files alongside the compiled JavaScript files.

When we load our website in the browser and open the developer tools, we can now view and debug the original source code, rather than the compiled code, by simply selecting the source map file in the developer tools. This makes it much easier to locate and fix issues in our code.
