SDKs & Client Libraries

0.8 package status: TypeScript and Dart/Flutter packages are published at 0.8.0. The published Rust crate is still 0.5.6-rc.0; use the 0.8 source checkout for experiments until a matching crate is published. Python SDK is Beta, is not production-ready, and has no 0.8 PyPI package.

KalamDB client libraries:

• TypeScript SDK for browser/Node.js apps and worker services
• Dart / Flutter SDK — start with kalam_sync (kalam init --languages dart); use kalam_link for live SQL only
• Rust SDK — source examples for native async Rust services; a 0.8 crate is not yet published
• Python SDK (Beta) for experimental async SQL and live query examples; see Python SDK status

Which One To Start With

• Building frontend + backend JS/TS apps: start at TypeScript Setup
• Building Dart/Flutter apps: kalam init --languages dart then Kalam Sync. Live SQL only: kalam_link setup
• Building Rust workers/services: review Rust SDK and build against the matching 0.8 source checkout
• Building Python services today: use the HTTP API Reference or PostgreSQL wire with psycopg; the Python SDK is beta

Shared Concepts Across SDKs

• JWT bearer auth for SQL and realtime flows
• SQL execution over /v1/api/sql
• WebSocket realtime subscriptions over /v1/ws
• Topic consume/ack for worker processing
• FILE column uploads and downloads (FileRef, BoundFileRef, TableId in Rust; BoundFileRef in TypeScript)
• Vector search through regular SQL (EMBEDDING, COSINE_DISTANCE, and indexed queries)
