Durable functions in TypeScript survive failures by using a deterministic step execution model with memoization and state persistence. This approach ensures long-running, event-driven workflows resume correctly without losing progress during unexpected crashes.

Durable event-driven workflows in TypeScript support three trigger types: events, cron schedules, and explicit manual invokes. This allows you to execute long-running functions reactively, on a schedule, or on-demand based on your specific application needs.

Long-running TypeScript workflows handle retries and idempotency through built-in error handling and cancellation patterns. Applying robust retry logic ensures transient failures don't break execution, while idempotency prevents duplicate side effects during automatic replay.

Durable execution for TypeScript functions includes built-in observability and logging guidance. This provides end-to-end tracing and failure handling visibility, helping you monitor state persistence and debug memoization issues across workflow steps.

The best way to structure fault-tolerant workflows is by isolating logic into deterministic steps with memoization and state persistence. Using real-world TypeScript patterns and templates ensures robust cancellation, error handling, and reliable long-running execution.
