GitHub Actions Pitfalls That Cost Devs Hours

GitHub Actions is powerful, but fragile configs often waste dev hours.

Common Pitfalls

1. Forgetting Workflow Triggers

A missing on: push or branch filter means workflows never run.

YAML
on:
  push:
    branches: [ main ]
Copy

2. Caching Gone Wrong Node.js cache misconfigs mean re-installing deps every build.

YAML
- uses: actions/cache@v3
  with:
    path: ~/.npm
    key: ${{ runner.os }}-npm-${{ hashFiles('**/package-lock.json') }}
Copy

3. Secret Leaks Echoing secrets in logs is a security disaster.

YAML
# Bad
run: echo ${{ secrets.API_KEY }}
Copy

Quick Checklist

✅ Define triggers correctly.

✅ Cache dependencies.

✅ Never log secrets.

What To Do Next

Audit your workflows. Optimize caches and verify triggers to save CI minutes and headaches.
