A template repository to bootstrap the creation of a JavaScript-based GitHub Action with built-in testing, linting, and publishing workflows.
actions/javascript-action is a template repository for creating custom GitHub Actions using JavaScript. It provides a starter kit with built-in testing, linting, packaging, and CI/CD workflows, streamlining the development process for action authors. The template handles common setup tasks, allowing developers to quickly build, test, and publish reusable actions.
Developers and teams building custom GitHub Actions who want a standardized, production-ready starting point with minimal configuration overhead.
It saves significant time by providing a pre-configured, opinionated setup that follows GitHub's best practices, includes essential tooling, and reduces the risk of common pitfalls in action development.
Create a JavaScript Action with tests, linting, workflow, publishing, and versioning
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Includes Jest for comprehensive testing with coverage badges, as shown in the README's test examples, ensuring action reliability before deployment.
Integrates ESLint and pre-configured GitHub workflows for linting, security scanning (CodeQL), and distribution checks, enforcing best practices automatically.
Uses Rollup to bundle all dependencies into a single distribution, which the README emphasizes as crucial for actions to work correctly in GitHub's environment.
Provides the @github/local-action utility for testing actions locally without pushing changes, improving development speed and debugging, as detailed in the setup section.
Requires multiple setup steps like installing dependencies, bundling with npm run bundle, and updating metadata files before writing core logic, which can be time-consuming for quick prototypes.
Locks users into specific tools like Rollup and Jest without built-in alternatives, limiting flexibility for teams accustomed to other build systems or testing frameworks.
Assumes familiarity with Node.js, npm scripts, and GitHub Actions concepts, making it less accessible for developers new to this ecosystem, as noted in the Node.js version requirements.
