TypeScript SDK

Architecture

• Layered, non-blocking by default
• Data buffered and flushed async to backend
• Node >= 18, ESM + CJS builds

Layer Flow

Public API → OpikClient → Domain (Trace/Span) → BatchQueues → REST Client → Backend

Critical Gotchas

• When changing dependencies or minimum versions, update and verify version references in README.md and integration README files in the same PR.

Flush Before Exit

// ✅ REQUIRED - especially in CLI/tests
await client.flush();
