twirp VS gRPC

The next time I want to build an API, I will probably make use of https://github.com/twitchtv/twirp. I like working with Protobuf and having strongly-typed and well-defined messages, but gRPC is way, way too much. It's obviously a Google product, built for what Google needs.

Use Protobuf for messages, but just use HTTP for transport.

- Twirp (Twitch light version of gRPC, with optional JSON encoding, HTTP1 support and without streaming) - https://github.com/twitchtv/twirp

There is another: twirp

And addition to what was mentioned there are also webrpc and twirp.

If you find one, you maybe also interested in twirp.

Twitch has a great framework for it https://twitchtv.github.io/twirp/docs/intro.html

We have better experience with https://goa.design/ than with https://github.com/twitchtv/twirp

Take a look at Twirp (https://github.com/twitchtv/twirp) open sourced by TwitchTv. It's a lot lighter weight than gRPC. It does use Protobufs but addresses some of the concerns you mentioned, such as being able to test with JSON payloads, works over HTTP 1.1 and HTTP/2, good client libraries, and doesn't require a proxy.

They address your concerns in more detail in the Twirp release announcement (2018) - https://blog.twitch.tv/en/2018/01/16/twirp-a-sweet-new-rpc-f...

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.
