rollup-plugin-regexp

A Rollup plugin for dynamic find-and-replace operations in bundled output using regular expressions or string matching. Version 5.0.1 is the latest stable release, published with a moderate cadence. Unlike static string replacement plugins, it supports RegExp patterns and replacement functions, enabling codemods and dynamic content injection. Ships TypeScript types and uses magic-string for accurate sourcemap preservation. A key differentiator is the shorthand syntax allowing key-value pairs for multiple replacements.
