@temporalio/create Package Initializer

@temporalio/create NPM | GitHub

@temporalio/create is an optional tool to set up a new Temporal project starting from our samples repo.

Usage​

See the Getting started guide for basic usage and environment set up before running this tool.

npx @temporalio/create@latest ./example

Optional flags​

  • --sample — Which sample to bootstrap the app with. You can use the name of a sample from github.com/temporalio/samples-typescript or use a GitHub URL. The URL can have a branch and/or subdirectory: for example, https://github.com/your-org/your-app/tree/main/foo/bar.
  • --list-samples — List available projects from our samples repo.
  • --use-yarn — Use Yarn instead of npm.
  • --[no-]git-init - Initialize an empty git repository.
  • --sdk-version <version> - Specify which version of the @temporalio/* npm packages to use.

Project structure​

Typically, the generated project consists of 4 main components:

  • Workflows
  • Activities
  • Worker that executes Workflows and Activities
  • A script to execute a Workflow (using a Temporal Client)

Working with the created project​

Most sample projects come with these scripts:

  • npm start — Run the Worker with ts-node (does not require a compilation step)
  • npm run start.watch — Watch files with nodemon and re-run Worker on change
  • npm run build — Compile TypeScript
  • npm run build.watch — Watch files and compile on change
  • npm run workflow — Execute a Workflow

If you aren't familiar with the tradeoffs between these choices, we recommend primarily running npm run start.watch to have a live-reloading Worker good enough for most situations, and then npm run workflow to start individual Workflow executions.
