GitHub Actions Workflow Generator
Adding CI to a new repository should take minutes, not a documentation deep-dive into GitHub Actions YAML syntax. This generator produces a working workflow file for four common stacks so you can drop it in and have tests running on the next push. One input controls the output: the Language dropdown — Node.js, Python, Go, or Rust. The generator returns a complete YAML file triggering on pushes to main and all pull requests, checking out the code, and running the language-specific steps: Node.js uses setup-node@v4 with Node 20, npm ci, and npm test; Python uses setup-python@v5 with Python 3.12 and pytest; Go uses setup-go@v5 with go build and go test; Rust uses rust-toolchain@stable with cargo build and cargo test. Save as .github/workflows/ci.yml and push. Extend with caching or a deploy job once the basics are green.
How to use
- Choose your options above
- Click Generate
- Copy your result
Detailed instructions
- Pick the language your project uses.
- Click Generate to produce the workflow YAML.
- Save it as .github/workflows/ci.yml.
- Commit and push to trigger the first run.
Use Cases
- •Bootstrapping CI on a brand-new repository
- •Standardising pipelines across multiple services
- •Remembering the exact GitHub Actions YAML shape
- •Adding automated tests to a project that has none
- •Teaching teammates how Actions workflows are structured
Tips
- →Add a dependency cache step once the pipeline is green for faster runs.
- →Use a matrix to test multiple language versions at once.
- →Pin action versions to a major tag like v4 for stability.
- →Add a separate job for linting to keep concerns clear.
FAQ
where do I save the generated file
Create a .github/workflows/ directory at the root of your repository and save the file there as ci.yml or any name ending in .yml. GitHub detects workflow files in that directory automatically and runs them on the declared events.
which events trigger the workflow
Pushes to the main branch and all pull requests. Edit the on: block to add other branches, tags, or a schedule trigger for nightly runs.
does the workflow include dependency caching
No — the starter is minimal so it is easy to read. Add the cache option to the setup action or a separate cache step once the pipeline runs correctly, which can significantly reduce build time for large dependency trees.
how do I use secrets in the workflow
Store sensitive values as encrypted secrets in your GitHub repository settings, then reference them as ${{ secrets.YOUR_SECRET_NAME }}. Never paste tokens or passwords directly into the workflow file, which is committed to the repository.
