protobuf-es VS connect-go

Yes, you can. You are mistaking protobuf with gRPC. See this for more information.

You can use this with connect: https://github.com/bufbuild/protobuf-es

Ah you should check out https://github.com/bufbuild/protobuf-es which feels great so far. Then there's connect by the same buf people but it has a grpc-web option https://connect.build/docs/web/getting-started/. The amount of code generated is also tiny, which I love.

I'd recommend looking into protobuf-ts (Timo from Buf) or protobuf-es (Buf maintained).

Not sure if it is a magic bullet, but it was definitely written by TypeScript developers, for TypeScript developers.

The generated TypeScript code is already pretty minimal because all serialization ops are implemented with reflection instead of generated code (which is only marginally slower than generated code in JS).

But you can also switch to generating JavaScript + TypeScript declaration files, which is truly minimal: JavaScript is an entire dynamic language, so we actually only generated a small snippet of metadata in the .js output, and create a class at run time with a function call. The generated typings (.d.ts) give you type safety, autocompletion in the IDE, and so on.

You can see the output here: https://github.com/bufbuild/protobuf-es/blob/main/packages/p...

In my opinion it's a good idea, it's the architecture we use at work, and it works well for us. The main limitation to be aware of is that many PaaS don't support gRPC traffic (because of the proxies used). For example, DigitalOcean App Platform or Heroku if I remember correctly. If the way you want to host your backend is OK with HTTP/2 and gRPC traffic, then it's not a limitation. One way around this limitation is to use the gRPC-Web protocol, or the Connect protocol (https://connect.build/). Unfortunately, Dart's gRPC client does not support the gRPC-Web protocol outside the web platform. So for a mobile application, it's not usable at the moment. (If this PR were accepted, it would solve the issue: https://github.com/grpc/grpc-dart/pull/557.) As for Connect, no client is currently offered by Buf for Dart. Don't hesitate if you want to know more. That said, I'd advise you to use the Connect implementation for Go to implement your backend. Connect will enable your server to speak all three protocols (gRPC, gRPC-Web and Connect), which is very useful in the long term. What's more, the code is cleaner, and you benefit from official support for observability with OpenTelemetry. If you don't know Buf (the creators of Connect),I suggest you visit their website: https://buf.build/. :-) Good luck!

As mentioned in the intro, we are going to use Buf and Connect as our tools. We’ll start by installing the dependencies.

Its annoying, because the rest of Connect (https://connect.build/) looks really really cool. But its no good for me in a complex app if I can't have multiple streams from the server :/

Consider checking out https://connect.build from https://buf.build. Supports a simpler protocol than grpc-web. Includes a js/ts client for frontend. Then you don’t necessarily need a rest layer, but could leverage the proxy your building.

Twirp (though I'd move to https://connect.build for my next project) to do JSON based RPC using protobufs.

my backend is go via https://github.com/bufbuild/connect-go , it's stable and all open source. just try and test it for your purpose. my project run all in 300 server more....
