rollup-plugin-modify

Rollup plugin for find-and-replace transformations on output bundles. Version 3.0.0 is current and stable, with no major release cadence. Supports both string/regex find with string/function replace, and a terse object syntax for multiple replacements. Uses magic-string under the hood for source map preservation. Unlike @rollup/plugin-replace, this plugin operates on the entire output file content rather than on AST nodes, making it suitable for regex-based codemods.
