CI/CD & Deployment

When to use this skill

• Configuring GitHub Actions workflows.
• Setting up automated deployments.
• Configuring test runners in CI.

1. GitHub Actions

• Triggers: on: push for branches, on: pull_request for verification.
• Caching: Always cache dependencies (npm, pip, composer) to speed up builds.

  - uses: actions/setup-node@v4
    with:
      node-version: 18
      cache: 'npm'
  

2. Deployment

• Atomic: Deployment should be atomic (zero downtime).
• Migration: Run DB migrations during deployment, but ensure backward compatibility.
• Secrets: Use repo secrets; never strict commit credentials.
