rollup-plugin-json-map-keys

Rollup plugin that recursively transforms JSON values into their dot-separated key paths, useful for i18n key generation or object value replacement. Latest version 1.2.0 (2025-11-22) requires rollup >= 2. The package has seen recent maintenance including dependency updates and path restructuring. It is part of a monorepo with webpack loader and Jest transformer equivalents. Key differentiators: designed specifically for Rollup, outputs JSON with key paths, supports custom prefix via options.
