EvalSourceMapDevToolPlugin will have stale caches then

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']
});
