actions/typescript-action

typescript-action is a template repository for creating GitHub Actions written in TypeScript.

The template addresses the need to bootstrap a new GitHub Action with production-ready tooling already in place. It provides a starting point that includes TypeScript compilation, a test suite, linting validation, automated workflows, publishing configuration, and versioning guidance. Developers clone or use the template to create their own action, then replace the source code in the src/ directory with their custom logic while updating the action.yml metadata file to define inputs, outputs, and descriptions specific to their use case.

This template suits developers building new GitHub Actions who want to start with TypeScript rather than JavaScript and prefer not to configure testing, linting, and CI workflows from scratch. The README points to a simpler Hello world JavaScript action repository as an alternative for those new to GitHub Actions development, suggesting this template is aimed at developers with some familiarity with the platform. The template requires Node.js and includes a .node-version file for version management.

The project maintains active validation workflows covering linting, continuous integration, distribution checks, and security analysis via CodeQL. Test coverage is tracked and displayed. The template is actively maintained as a reference implementation, with documentation that guides users through initial setup, dependency installation, TypeScript packaging, and test execution.
