format-json

A JSON formatter library for Node.js (v1.0.3, stable, no recent updates) offering three serialization styles: 'diffy' (comma-first for reduced version control diffs), 'plain' (standard pretty-print), and 'terse' (compact). Unlike JSON.stringify, it provides a unique comma-first format optimized for diff readability. Minimal dependencies; synchronous only; no streaming support.
