Typescript handler functions

Does Runpod support Typescript handler functions for serverless endpoints, or only Python?

We're using Runpod to accelerate scientific workloads and just shelling out to C++ binaries in the serverless function. Since the rest of our backend is Typescript it's mildly unpleasant to support Python for this single use-case.

In your docker file you set the entry point. So technically you could just run bun on deno on it.

The runpod Python library, I belive, is mostly to get the data of the request.

I am not sure how the library gets that data (maybe environment variables) but it should be doable in typescript

Or call deno onces the python entry point as gotten the data

Oh so the existing Python handler is basically standing up a HTTP endpoint that Runpod then calls with the request?

I am not a runpod employee and I don't want to give false information.

But that's what I am getting from quickly looking at the library code

The simplest solution i think still using Python just for the entry and then pass the rest to typescript

You can find the entry point code and serverless code here

You might want to look into the load balancing endpoint type, which doesn't need the serverless SDK and instead simply routes requests to any webserver running in a worker.

https://docs.runpod.io/serverless/load-balancing/overview

Something to keep in mind is load balancing endpoints don't maintain a queue, so if you need that functionality you might have to look into emulating the runpod SDK's behavior in typescript or maintain a queue elsewhere in your application
