@tanstack/workflow-core@0.0.1

Initial public release of @tanstack/workflow-core.

pnpm add @tanstack/workflow-core zod

Type-safe durable execution engine for TypeScript. Closure-based workflows with replay-driven durability, pause/resume on approvals and signals, typed middleware that extends ctx, an append-only event log that doubles as the UI transport, and a pluggable RunStore interface.

Primitives on ctx: step, sleep / sleepUntil, waitForEvent, approve, now, uuid, retry, emit. Cross-version routing via previousVersions. Webhook entry point alongside long-running runWorkflow. In-memory RunStore with push subscription.

Status

Pre-alpha. Public API stable in shape; bindings (React, Solid, Vue, Svelte), storage adapters (Postgres, SQLite, Durable Objects), and devtools are forthcoming.

Extracted from @tanstack/ai-orchestration (Alem Tuzlak + Tom Beckenham). The AI-specific surface (agents, orchestrators) stays in ai-orchestration and composes on top.

Caveat

This build was published from a local machine while the TanStack org's GitHub Actions billing is blocked. No npm provenance attestation is attached. Future releases through the Release workflow will sign.
