Supabase Edge Runtime

A web server based on Deno runtime, capable of running
JavaScript, TypeScript, and WASM services. Edge Runtime is built and maintained
by the Supabase team. For more details, read the
intro blog post.

You can use it to:

• Locally test and self-host Supabase's Edge Functions (or any Deno Function)
• As a programmable HTTP Proxy: You can intercept / route HTTP requests

WARNING: Beta Software. There will be breaking changes to APIs / Configuration
Options

Architecture

The edge runtime can be divided into two runtimes with different purposes.

• Main runtime:
  • An instance for the main runtime is responsible for proxying the
    transactions to the user runtime.
  • The main runtime is meant to be an entry point before running user
    functions, where you can authentication, etc. before calling the user
    function.
  • Has no user-facing limits
  • Has access to all environment variables.
• User runtime:
  • An instance for the user runtime is responsible for executing users' code.
  • Limits are required to be set such as: Memory and Timeouts.
  • Has access to environment variables explictly allowed by the main runtime.
