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.
