I’ve built an alternative to gRPC Gateway that adds some long-requested features: streaming support, OpenAPI 3, better documentation, and improved error handling. Some of these features are not in the roadmap for the gRPC Gateway project as far as I am aware, so I decided to build a solution that fills this gap.
Why this project?
Streaming Support – gRPC Gateway doesn’t support streaming HTTP mappings such as web socket or SSE. This projects aims to provide some support here.
OpenAPI 3 – Full OpenAPI 3 compatibility instead of OpenAPI 2. This one was a pain for two projects at work and I wanted to have an OpenAPI 3 support.
Better Error Handling – More robust and configurable error transformations.
Improved Documentation – Easier onboarding and clearer examples.
Who is this for?
If you use gRPC but need more HTTP/JSON mapping options with streaming and OpenAPI 3, this might be a good fit. It’s not a one-size-fits-all replacement, but it fills some of these gaps.
Would love to hear feedback! Try it out and let me know what you think. I also want to work on a binary version of this that can be used as a sidecar so that other languages can use it as well without having to involve Go necessary but I want to first make sure there is a real need for it.
