prost VS grpc-gateway

The benchmark is not comparing apples to apples.

prost is the most widely used Protobuf implementation in Rust, maintained by the Tokio organization. prost generates structs and serialization/deserialization code for you.

easyproto according to GitHib Search is used only by two projects. easyproto provides primitives for serializing and deserializing Protobuf, and requires hand writing code to do both.

A fair comparison would be prost vs google.golang.org/protobuf, or easyproto vs parts of quick-protobuf.

In most cases you can make Go as fast as Rust, but from my experience writing performance-sensitive code in Go requires significantly larger time investment and overall requires deeper language expertise. Pebble (RocksDB replacement in Go by CockroachDB) is a good example of this, the codebase is littered with hand-inlined[1] functions, hand-unrolled loops and it's not[2] even using Go memory management for performance critical parts, it's using the C memory allocator and manual memory management.

You could use Protocol buffers to define a message type, then use prost to generate encoding/decoding code for that type.

Thanks but that doesn't seems to support `json_mapping` , there is a draft available but not sure when it will get merged https://github.com/tokio-rs/prost/pull/558

Hi r/rust, I have a question regarding tonic-build (or prost-build).

Currently, I'm making some stuff by using protobuf via prost. Maybe you know, protobuf v3 treats all fields as optional, so it is pain to unwrap every nested field.

Note: one additional key feature currently missing from Prost is Proto2 extensions.

it lacks flexibility but i really enjoy grpc-gateway for 99% of my work

gRPC Gateway is a protoc plugin that reads gRPC service definitions and generates a reverse proxy server that translates a RESTful JSON API into gRPC.

I don't have any example that's public atm, but the guide in grpc-gateway is pretty clear/can be followed step by step.

To integrate with Fiber, I used the Fiber Adaptor (also pretty straightforward): https://docs.gofiber.io/api/middleware/adaptor

I wonder if they would be happy with something like this: https://github.com/grpc-ecosystem/grpc-gateway

Protobuf is used is massively scaled services like firebase. But you'll still see JSON in streamed realtime services like AWS Kinesis. Hopefully google had a return on investment for creating and using this protocol, but it's not hard to prove that it's far from essential. Out of apparent convenience I use grpc-gateway so I can expose both Protobuf and JSON, but honestly I wouldn't do it again

GRPC is an alternative to rest, rest and GRPC both use the http protocol. But you won’t be able to use fetch to call a GRPC endpoint, you should look into setting up a GRPC proxy within the application(hopping you have access to the source code) grpc-gateway. If you don’t have access you’ll have to create a new container that proxies the calls

(There is an option called google.api.http, that lets you set up a URL that can be used to make HTTP/1 REST requests, which get translated to gRPC calls if you're using grpc-gateway as a proxy in front of your service. That has nothing to do with the requests that are made by gRPC clients and servers themselves.)

Have you looked at https://github.com/grpc-ecosystem/grpc-gateway ?

protoc-gen-grpc-gateway — plugin for creating a gRPC REST API gateway. It allows gRPC endpoints as REST API endpoints and performs the translation from JSON to proto. Basically, you define a gRPC service with some custom annotations and it makes those gRPC methods accessible via REST using JSON requests.
