export functions in normalize.ts

[wangcheng]

Hi, team. I am developing a Connect client for Weixin Miniprogram. "Weixin Miniprogram" uses a special JS runtime that doesn't support fetch and and AbortSignal. So I have to port the logic to use its own fetching function.

Since I don't have AbortSignal I decided to drop signal support and not use functions in run-call. That means I need to use functions in normalize directly. Now I just copied the code to my repo like this.

I think it will be convenient to export them for third-party developers like me. Or do the team have a better suggestions for how to implement a client on runtimes that don't support fetch and AbortSignal?

fetch is not a hard requirement, you will have to implement UniversalClientFn and use that with the transports in @connectrpc/connect. In fact, node support is implemented in the same way, @connectrpc/connect-node is a good source for reference.

AbortSignal on the other hand is used throughout, the best way would be to polyfill AbortSignal and AbortController. Previous versions of connect ran tests against browsers without AbortSignal using a polyfill.

It is great to see connect being used in new runtimes! Let us know if you need anything.

@srikrsna-buf Thank you for pointing out the UniversalClientFn. It is very useful!
