Routing

Overview

Edge Functions support GET, POST, PUT, PATCH, DELETE, and OPTIONS. This means you can build complete REST APIs in a single function:

Deno.serve(async (req) => {
  const { method, url } = req
  const { pathname } = new URL(url)

  // Route based on method and path
  if (method === 'GET' && pathname === '/users') {
    return getAllUsers()
  } else if (method === 'POST' && pathname === '/users') {
    return createUser(req)
  }

  return new Response('Not found', { status: 404 })
})

Edge Functions allow you to build APIs without needing separate functions for each endpoint. This reduces cold starts and simplifies deployment while keeping your code organized.

HTML content is not supported. GET requests that return text/html will be rewritten to text/plain. Edge Functions are designed for APIs and data processing, not serving web pages. Use Supabase for your backend API and your favorite frontend framework for HTML.

Example
