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.
