A developer used Claude AI in a "Ralph loop" to build a complete IndexedDB implementation in TypeScript overnight, targeting 90% Web Platform Test coverage. The AI-generated code achieved 95% pass rate on selected tests and 77.4% on comprehensive tests, comparing favorably to fake-indexeddb's 82.8%. The project cost about $7 and demonstrates how LLMs can now create complex database implementations from scratch.
