API

webpack-plugin-replace(options)

options.exclude

Type: Array|String|Function|RegExp
Default: false

If multiple conditions are provided, matching any condition will exclude the filepath, which prevents any alterations.

Note: By default, nothing is excluded!

options.include

Type: Array|String|Function|RegExp
Default: true

If multiple conditions are provided, matching any condition will include & scan the filepath for eligible replacements.

Note: By default, all filepaths are included!

options.patterns

Type: Array
Default: []

An array of RegExp pattern definitions. Each definition is an object with regex <RegExp> and value <String|Function> keys. If value is a function, it takes the same arguments as String.prototype.relace.

options.values

Type: Object
Default: {}

An object whose keys are strings that should be replaced and whose values are strings the replacements.

If desired, you may forgo the values key & declare your key:value pairs directly to the main configuration. For example:

{
  exclude: /node_modules/,
  values: {
    'process.env.NODE_ENV': JSON.stringify('production'),
  }
}

// is the same as:

{
  exclude: /node_modules/,
  'process.env.NODE_ENV': JSON.stringify('production'),
}
