api-diff
Launched this week
Backend changes a field. Frontend breaks silently.
TypeScript types go stale. Nobody notices until
users complain.
api-diff intercepts every fetch call and deep-diffs
the actual response against a schema you define once.
When something drifts, you know immediately.
Supports wildcard routes, strict mode, granular
ignore patterns, and an onDrift callback for Sentry
or analytics.
Zero dependencies. Full TypeScript support.
