#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.

#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:

import { rspack } from '@rspack/core';

export default {
  devtool: false,
  plugins: [new rspack.EvalSourceMapDevToolPlugin({})],
};

#Exclude vendor maps

The test, include, and exclude options match module resource paths, rather than output bundle filenames. The following example excludes source maps for modules in node_modules:

new rspack.EvalSourceMapDevToolPlugin({
  exclude: /[\\/]node_modules[\\/]/,
});

#Options

#test

• Type: string RegExp [string, RegExp]

Generate source maps for modules whose resource paths match the given value. By default, this option does not restrict which modules are included.

#include

• Type: string RegExp [string, RegExp]

Include source maps for module paths that match the given value.

#exclude

• Type: string RegExp [string, RegExp]

Exclude modules that match the given value from source map generation.

#module

• Type: boolean

Indicates whether loaders should generate source maps (defaults to true).

#columns

• Type: boolean

Indicates whether column mappings should be used (defaults to true).
