TypeScript SDK v1.15.0 documentation

[mintlify]

Documents user-facing features shipped in TypeScript SDK v1.15.0.

What's new

Signals and InvocationReference (develop/ts/service-communication.mdx)

• ctx.signal(name) — wait for a named signal on the current invocation
• ctx.invocation(id) — get an InvocationReference to send signals, cancel, or attach to any invocation by ID
• The old ctx.cancel() / ctx.attach() are now deprecated in favour of ctx.invocation(id).cancel() / .attach()

PauseError (develop/ts/error-handling.mdx)

• New restate.PauseError that can be thrown inside a ctx.run closure to explicitly pause an invocation instead of retrying it

onJournalMismatchErrors option (services/configuration.mdx)

• New service/handler option to control what happens on a journal mismatch (non-determinism) error: "retry" (default), "pause", or "fail"

Flow control: ctx.scope() SDK API (services/flow-control.mdx)

• Documents the new ctx.scope(scopeKey) method that routes outgoing calls through a named flow-control scope from within a handler
• Also documents the limitKey option for hierarchical concurrency limits

@restatedev/restate-sdk-gen preview package (new page: develop/ts/sdk-gen.mdx)

• New generator-based API for authoring handlers with concurrent durable tasks via spawn
• Covers: gen/execute, run, all/race/any/allSettled/select, spawn/interrupt, cooperative cancellation with channels, contextLocal, service clients, and common pitfalls

@restatedev/restate-sdk-tunnel preview package (new page: services/deploy/tunnel.mdx)

• Reverse-tunnel client for Restate Cloud: serves a deployment over an outbound connection, no public ingress required
• Covers setup, zero-config Kubernetes operator mode, graceful shutdown, and comparison with restate.serve()

All preview features require restate-server 1.7 with the relevant experimental flags enabled (noted inline).
