When analyzing a GitHub Actions workflow:
# Example workflow to analyze
name: Deploy to Cloudflare
on:
push:
branches: [main]
pull_request:
branches: [main]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: '20'
cache: 'npm'
- run: npm ci
- run: npm run build
- run: npm test
deploy:
needs: build
runs-on: ubuntu-latest
if: github.ref == 'refs/heads/main'
steps:
- uses: actions/checkout@v4
- name: Deploy to Cloudflare
uses: cloudflare/wrangler-action@v3
with:
apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
Analysis checklist:
Track these workflow performance metrics:
{
"workflow_name": "Deploy to Cloudflare",
"metrics": {
"total_duration_seconds": 180,
"job_durations": {
"build": 120,
"test": 60,
"deploy": 45
},
"cache_hit_rate": 0.85,
"parallel_jobs": 2,
"sequential_jobs": 1,
"potential_parallel_time": 60,
"actual_parallel_time": 120,
"optimization_opportunity": "50% time reduction possible"
}
}
Key metrics:
Before:
jobs:
build:
runs-on: ubuntu-latest
steps:
- run: npm run build
test:
needs: build
runs-on: ubuntu-latest
steps:
- run: npm test
lint:
needs: test
runs-on: ubuntu-latest
steps:
- run: npm run lint
After (parallel execution):
jobs:
quality-checks:
runs-on: ubuntu-latest
strategy:
matrix:
task: [build, test, lint]
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: '20'
cache: 'npm'
- run: npm ci
- run: npm run ${{ matrix.task }}
Time saved: 66% (3 sequential jobs ā 1 parallel job)
Before (no caching):
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: '20'
- run: npm ci # Downloads all dependencies every time
- run: npm run build
After (with caching):
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: '20'
cache: 'npm' # Cache npm dependencies
- run: npm ci --prefer-offline
- name: Cache build output
uses: actions/cache@v4
with:
path: dist
key: build-${{ hashFiles('src/**') }}
- run: npm run build
Time saved: 30-50% on average
Before (runs all jobs always):
jobs:
deploy-staging:
runs-on: ubuntu-latest
steps:
- name: Deploy to staging
run: wrangler deploy --env staging
deploy-production:
runs-on: ubuntu-latest
steps:
- name: Deploy to production
run: wrangler deploy --env production
After (conditional):
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- name: Deploy to staging
if: github.ref == 'refs/heads/develop'
run: wrangler deploy --env staging
- name: Deploy to production
if: github.ref == 'refs/heads/main'
run: wrangler deploy --env production
Cost saved: 50% GitHub Actions minutes
Before (rebuilding in each job):
jobs:
build:
runs-on: ubuntu-latest
steps:
- run: npm run build
deploy:
needs: build
runs-on: ubuntu-latest
steps:
- run: npm run build # Rebuilding!
- run: wrangler deploy
After (using artifacts):
jobs:
build:
runs-on: ubuntu-latest
steps:
- run: npm run build
- uses: actions/upload-artifact@v4
with:
name: dist
path: dist/
deploy:
needs: build
runs-on: ubuntu-latest
steps:
- uses: actions/download-artifact@v4
with:
name: dist
- run: wrangler deploy
Time saved: Eliminates duplicate builds
