Edge ingestion runs on Cloudflare Workers + Queues; storage is Neon Postgres with Row-Level Security for multi-tenant isolation; the API layer is Hono. A Rust port using workers-rs is in progress targeting sub-10ms p95 latency. Live at klinder-oss.vercel.app.

Question 5

Accepted Answer

diffcore is a fast WebAssembly JSON diff engine for JavaScript and TypeScript, built by Dibbayajyoti Roy in Rust and published on npm.

It ships applyPatch and revertPatch for state sync, undo/redo, and optimistic UI, includes a React useDiff hook and a CLI, plus a streaming engine for multi-GB files. Benchmarks at 3.3 to 4.1 times optimized pure-JS diff (360–490 MB/s sustained). Runs on Node, browsers, Bun, Deno, Cloudflare Workers, Vercel Edge, Electron, and Tauri. Install: npm install diffcore.
