Examples#

Basic Use Case#

You can use the following code to replace the configuration option devtool: eval-source-map with an equivalent custom plugin configuration:

module.exports = {
  // ...
  devtool: false,
  plugins: [new rspack.EvalSourceMapDevToolPlugin({})],
};

Exclude Vendor Maps#

The following code would exclude source maps for any modules in the vendor.js bundle:

new rspack.EvalSourceMapDevToolPlugin({
  exclude: ['vendor.js'],
});
