Workerd: The Open Source Cloudflare Workers Runtime

• workerd

  37 5,681 9.9 C++

  The JavaScript / Wasm runtime that powers Cloudflare Workers

  

The config format is defined and documented here:

https://github.com/cloudflare/workerd/blob/main/src/workerd/...

We definitely need to provide more higher-level documentation around this, which we're working on, but if you're patient enough to read the schemas then everything is there. :)

To act as a proxy, you would define an inbound socket that points to a service of type `ExternalServer`. There are config features that let you specify that you want to use proxy protocol (where the HTTP request line is a full URL) vs. host protocol (where it's just a path, and there's a separate Host header), corresponding to forward and reverse proxies.

Next you'll probably want to add some Worker logic between the inbound and outbound. For this you'd define a second service, of type `Worker`, which defines a binding pointing to the `ExternalServer` service. The Worker can thus send requests to the ExternalServer. Then you have your incoming socket deliver requests to the Worker. Voila, Workers-based programmable proxy.

Again, I know we definitely need to write up a lot more high-level documentation and tutorials on all this. That will come soon...

  86 8,518 10.0 Svelte

  Open-source developer platform to turn scripts into workflows and UIs. Fastest workflow engine (5x vs Airflow). Open-source alternative to Airplane and Retool.

  

This is great, thank you for open-sourcing. One limitation is see with this model which is clearly stated in the post is that it is javascript/wasm and HTTP servers only. The deployable workers model is a great one and I had hoped to provide an adapter for the open-source windmill[1] project by transforming the normal scripts that are our units of execution into http servers runnable in workderd.

We support typescript (deno), go and python. Short of those languages becoming 100% transpilable to wasm, we will have to fallback to use firecracker or keep our current system implemented from scratch using nsjail for sandboxing and a fork for each process.

Is there an ETA on Miniflare v3? Ran into a problem recently using overlapping keys with forward slashes as they were not sanitized properly: https://github.com/cloudflare/miniflare/issues/167
