Azure Functions now supports custom
handlers in Flex consumption. Custom handlers are lightweight web servers that
receive events from the Functions host. Any language that supports HTTP
primitives can implement a custom handler.
Custom handlers are best suited for
situations where you want to:
- Implement
a function app in a language that's not currently offered out-of-the box, such
as Go or Rust.
- Implement
a function app in a runtime that's not currently featured by default, such as
Deno.
With custom handlers, you can use triggers and input and output
bindings via extension bundles.
