Durable TypeScript patterns map async-await workflows by translating distributed execution specs into Resonate SDK constructs like ctx.run and ctx.rpc. This ensures deterministic durable execution and correct failure semantics for long-running processes.

Replay-safe side effect execution in durable functions ensures that operations like network calls only run once during recovery. The Resonate TypeScript SDK handles this by caching results and using durable checkpoints to prevent duplicate executions when resuming after crashes.

To ensure idempotency with promise IDs in TypeScript durable execution, you implement specific promise ID strategies that distinguish between cached results and new executions. This guarantees that multi-step workflows do not duplicate side effects during process recovery or cross-process coordination.

Yes, the Resonate TypeScript SDK supports cross-process RPC coordination through beginRpc semantics. It enables you to hand off between local and remote execution safely, satisfying requirements for serializable return values and durable promise-based coordination across distributed workers.

The best way to design a resilient order-processing saga in TypeScript is using durable execution to span local steps and remote workers. By applying deterministic coding practices and idempotent promise IDs, the saga safely preserves state and resumes after failures.

Durable workflows break determinism during crash recovery when side effects are not replay-safe or return values are non-serializable. Enforcing deterministic coding practices and using correct ctx.run semantics ensures durable checkpoints recover without invalid state.
