What is source-map-loader?

The source-map-loader package is used to load source map data from existing source files. It extracts source maps from the source files (like JavaScript files) when they are included in the webpack build process. This allows for better debugging capabilities because the browser developer tools can map the generated code back to the original source code, which is particularly useful when working with transpiled languages or minified code.

What are source-map-loader's main functionalities?

Extracting source maps

This webpack configuration snippet demonstrates how to use source-map-loader to extract source maps from JavaScript files before they are processed by other loaders. The 'enforce: pre' property ensures that the source-map-loader runs before other loaders.

module.exports = {
  module: {
    rules: [
      {
        test: /\.js$/,
        use: ['source-map-loader'],
        enforce: 'pre'
      }
    ]
  }
};
