ts-proto VS gRPC

I created it so that I could use `protoc` and `ts-proto` to convert the otel proto files into typescript files.

Re libraries incompatible with certain typescript versions - e.g. protobufjs fix - it’s been my experience that you want to try and only use compilers specific to each library and compile libraries separately. It’s unfortunate but the JS community often tries to run all JS for a project through the same single compiler tool chain, using one global version of the compiler instead of relying on and effectively linking the JS output for each library. Unless you routinely rewrite third-party libraries to match your toolchain’s expectations, you’re going to have a hard time doing that.

For a library that generates code, that’s a special case, as the code it generates must target a particular language version. You have three choices: 1. Upstream a fix as you propose; 2. Side-by-side install both TS 4.6 and TS 4.7 using workspaces or sub-projects and have some of your code compile with 4.6 and then link the results or 3. Find a replacement that is updated to 4.7. For example, https://github.com/stephenh/ts-proto has 4.7 support listed in its readme.

With ts-proto, I can pass a --ts_proto_opt=outputServices=generic-definitions as a flag to protoc to generate "generic service definitions". These definitions contain descriptors for each method, which allows to generate server and client stubs at runtime, and also generate strong types for them at compile time.

Curious to see their typescript implementation and how it compares with https://github.com/stephenh/ts-proto which works great for grpc-web.

I'm planning on modding https://github.com/stephenh/ts-proto to use https://github.com/ianstormtaylor/superstruct on the client.

We also use protobufs and typescript, so we use ts-proto for codegen + binding to grpc services.

Fwiw I maintain ts-proto (https://github.com/stephenh/ts-proto/) and it'd be cool to have the functionality you're building supported in ts-proto at somepoint, if you're curious/want to poke around/etc. :-) Right now there is grpc support via the improbable-eng grpcwebproxy, but supporting GCP's transcoding as well would be great.

gRPC, built on HTTP/2, inherently supports flow control. The server can push updates, but it must also respect flow control signals from the client, ensuring that it doesn't send data faster than what the client can handle.

Yes, grpc_cli tool uses essentially the same mechanism except implemented as a grpc service rather than as a stubby service. The basic principle of both is implementing the C++ proto library's DescriptorDatabase interface with cached recursive queries of (usually) the server's compiled in FileDescriptorProtos.

The primary difference between what grpc does and what stubby does is that grpc uses a stream to ensure that the reflection requests all go to the same server to avoid incompatible version skew and duplicate proto transmissions. With that said, in practice version skew is rarely a problem for grpc_cli style "issue a single RPC" usecases: even if requests do go to two or more different versions of a binary that might have incompatible proto graphs, it is very common for the request and response and RPC to all be in the same proto file so you only need to make one RPC in the first place unless you're using an extension mechanism like proto2 extensions or google.protobuf.Any.

While gRPC and Apache Thrift have served the microservice architecture well, CloudWeGo's advanced features and performance metrics set it apart as a promising open source solution for the future.

The loadBalancingConfig is what we use in order to decide which policy to go for (round_robin in this case). This JSON representation is based on a protobuf message, then why does the name resolver returns it in the JSON format? The main reason is that loadBalancingConfig is a oneof field inside the proto message and so it can not contain values unknown to the gRPC if used in the proto format. The JSON representation does not have this requirement so we can use a custom loadBalancingConfig .

The Dart implementation of gRPC which puts mobile and HTTP/2 first. It's built and maintained by the Dart team. gRPC is a high-performance RPC (remote procedure call) framework that is optimized for efficient data transfer.

gRPC is a high-performance, open-source RPC (Remote Procedure Call) framework initially developed by Google. It uses Protocol Buffers for serialization and supports bidirectional streaming.

In general, tunneling through HTTP2 turns out to be a great choice. There is a RPC protocol built on top of HTTP2: gRPC[1].

This is because HTTP2 is great at exploiting a TCP connection to transmit and receive multiple data structures concurrently - multiplexing.

There may not be a reason to use HTTP3 however, as QUIC already provides multiplexing.

I expect that in the future most communications will be over encrypted HTTP2 and QUIC simply because middleware creators can not resist to discriminate.
