SpacetimeDB TypeScript SDK

Build real-time TypeScript clients that connect directly to SpacetimeDB modules. The SDK provides type-safe database access, automatic synchronization, and reactive updates for web apps, Node.js, Deno, Bun, and other JavaScript runtimes.

HALLUCINATED APIs — DO NOT USE

These APIs DO NOT EXIST. LLMs frequently hallucinate them.

// WRONG PACKAGE — does not exist
import { SpacetimeDBClient } from "@clockworklabs/spacetimedb-sdk";

// WRONG — these methods don't exist
SpacetimeDBClient.connect(...);
SpacetimeDBClient.call("reducer_name", [...]);
connection.call("reducer_name", [arg1, arg2]);
