library2.0.0jsnpmunverified

A CLI tool by Cloudflare for quantifying UI framework migrations (e.g., Backbone to React). Version 2.0.0 analyzes source and test files by framework, counts lines of code (LOC), tracks dependencies via webpack stats, and outputs structured JSON for reporting. Stable, low maintenance, with config file support. Differentiator: provides dependency feedback and migration stats specific to framework comparisons.
