Overview
What This Skill Does
Netlify Functions lets you write serverless functions that run on Netlify's infrastructure. It covers the modern default export syntax, TypeScript support, path and method routing, background functions for long-running tasks, scheduled functions via cron, and streaming responses.
Application
When to use this Skill
- Configuring integration settings for custom agent workflows.
- Optimizing query execution and response latency in production.
- Developing clean, standard-compliant implementations for enterprise services.
- Troubleshooting connection timeouts and authentication handshakes.
- Monitoring API rate limits and execution pipelines programmatically.

Netlify Functions
Modern Syntax
Always use the modern default export + Config pattern. Never use the legacy exports.handler or named handler export.
import type { Context, Config } from "@netlify/functions";
export default async (req: Request, context: Context) => {
return new Response("Hello, world!");
};
export const config: Config = {
path: "/api/hello",
};
The handler receives a standard Web API Request and returns a Response. The second argument is a Netlify Context object.
File Structure
Place functions in netlify/functions/:
netlify/functions/
_shared/ # Non-function shared code (underscore prefix)
auth.ts
db.ts
items.ts # -> /.netlify/functions/items (or custom path via config)
users/index.ts # -> /.netlify/functions/users
