TypeScript SDK developer guide
Build Temporal Applications with the TypeScript SDK.
This guide provides a comprehensive overview of the structures, primitives, and features used in Temporal Application development.
Core application
Use the essential components of a Temporal Application (Workflows, Activities, and Workers) to build and run a Temporal application.
Temporal Client
Connect to a Temporal Service and start a Workflow Execution.
Testing
Set up the testing suite and test Workflows and Activities.
Failure detection
Explore how your application can detect failures using timeouts and automatically attempt to mitigate them with retries.
Workflow message passing
Send messages to and read the state of Workflow Executions.
Interrupt a Workflow feature guide
Interrupt a Workflow Execution with a Cancel or Terminate action.
Asynchronous Activity Completion
Complete Activities asynchronously.
Versioning
Change Workflow Definitions without causing non-deterministic behavior in current long-running Workflows.
Observability
Configure and use the Temporal Observability APIs.
Debugging
Explore various ways to debug your application.
Schedules
Run Workflows on a schedule and delay the start of a Workflow.
Data encryption
Use compression, encryption, and other data handling by implementing custom converters and codecs.
Durable Timers
Use Timers to make a Workflow Execution pause or "sleep" for seconds, minutes, days, months, or years.
Child Workflows
Explore how to spawn a Child Workflow Execution and handle Child Workflow Events.
Continue-As-New
Continue the Workflow Execution with a new Workflow Execution using the same Workflow ID.
Interceptors
Manage inbound and outbound SDK calls, enhance tracing, and add authorization to your Workflows and Activities.
