GitHub Actions Workflow Generator (CI/CD YAML)

GitHub Actions runs your tests and deployments on every push. A workflow is a YAML file in .github/workflows/, and small mistakes in indentation or quoting break it. This generator writes a clean workflow: push, pull-request, scheduled and manual triggers; Node.js, Python, Java or Go with a version matrix and dependency caching; install, test and build steps; least-privilege permissions; and optional deployment to GitHub Pages or a Docker image on GitHub’s container registry.

How to use this tool

1. Name the workflow and list the branches to watch.
2. Choose triggers: pull requests, a cron schedule (UTC) and manual runs.
3. Pick the language and the versions to test; adjust the install, test and build commands.
4. Optionally add a Pages or Docker deploy, then save the file in .github/workflows/.

Formula

on (triggers) → jobs.build: runs-on, strategy.matrix, steps (checkout → setup → install → test → build) → optional deploy job

Every value that YAML could misread is quoted: versions such as 3.10 stay strings instead of becoming 3.1. permissions: contents: read limits the GITHUB_TOKEN; deploy jobs ask only for what they need (pages: write and id-token: write, or packages: write). Deploys run only for pushes to the first branch, never for pull requests.

Example

With Node.js and version 24 the workflow checks out the code, runs actions/setup-node@v7 with node-version: ${{ matrix.node-version }} over the matrix ['24'] and npm caching, then runs npm ci and npm test on ubuntu-latest for each push to main.
