React Router Migration Helper
JSON →A CLI tool and library for migrating React Router v3 route configurations to v4. Version 1.0.5 is the latest and stable, with no recent updates since 2019. It converts JSX-based route definitions into a JSON object compatible with React Router v4's new declarative routing model. Unlike manual migration scripts, this tool automates the conversion of static routes, index routes, and nested routes. However, it does not handle dynamic routes (splat) or base URL replacements, as noted in its TODO. The package is no longer actively maintained and should be considered a one-time migration helper rather than a long-term dependency.
