Usage

Options

For all options please refer to docs.

This plugin accepts all @rollup/plugin-replace options, and some extra options that are specific to this plugin.

options.values

• Type: { [find: string]: Replacement } | ReplaceItem[]
• Default: []

type ReplaceItem = {
  /** Supply a string or RegExp to find what you are looking for. */
  find: string | RegExp

  /**
   * Can be a string or a function.
   * - If it's a string, it will replace the substring matched by pattern. A number of special replacement patterns are supported
   * - If it's a function, it will be invoked for every match and its return value is used as the replacement text.
   */
  replacement: Replacement
}
type Replacement = string | ((id: string, match: RegExpExecArray) => string)

Comparing with @rollup/plugin-replace, find option supports regex pattern.

Example:

Replace({
  values: [
    {
      find: /apples/gi,
      replacement: 'oranges',
    },
    {
      find: 'process.env.NODE_ENV',
      replacement: '"production"',
    },
  ],
})
