EvalSourceMapDevToolPlugin

This plugin enables more fine grained control of source map generation. It is also enabled automatically by certain settings of the devtool configuration option.

new webpack.EvalSourceMapDevToolPlugin(options);

Options

The following options are supported:

  • test (string|RegExp|array): Include source maps for modules based on their extension (defaults to .js and .css).
  • include (string|RegExp|array): Include source maps for module paths that match the given value.
  • exclude (string|RegExp|array): Exclude modules that match the given value from source map generation.
  • append (string): Appends the given value to the original asset. Usually the #sourceMappingURL comment. [url] is replaced with a URL to the source map file. false disables the appending.
  • moduleFilenameTemplate (string): See output.devtoolModuleFilenameTemplate.
  • module (boolean): Indicates whether loaders should generate source maps (defaults to true).
  • columns (boolean): Indicates whether column mappings should be used (defaults to true).
  • protocol (string): Allows user to override default protocol (webpack-internal://)

Examples

The following examples demonstrate some common use cases for this plugin.

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 webpack.EvalSourceMapDevToolPlugin({})],
};

Exclude Vendor Maps

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

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