Overview
Vercel Functions provide serverless execution for APIs and background tasks. The Edge Runtime enables low-latency execution closer to users.
Vercel Functions
- Define serverless functions in the project structure.
- Use environment variables for configuration.
- Review logs for errors and performance.
Edge Runtime
- Use the Edge Runtime for low-latency execution.
- Validate compatibility with the Edge runtime constraints.
Cron Jobs
- Schedule jobs with cron definitions.
- Use cron for periodic maintenance tasks or sync jobs.
Routing and Middleware
- Apply routing middleware for request handling.
- Use headers, rewrites, and redirects to control traffic.
Complementary Skills
When using this skill, consider these related skills (if deployed):
- vercel-deployments-builds: Deployment workflow and release controls.
- vercel-networking-domains: Routing, headers, and edge caching.
- vercel-observability: Logs and tracing for function debugging.
Note: Complementary skills are optional. This skill is fully functional without them.
