Twirp is a framework for service-to-service communication emphasizing simplicity and minimalism. It generates routing and serialization from API definition files and lets you focus on your application's logic instead of thinking about folderol like HTTP methods and paths and JSON.
Define your service in a Protobuf file and then Twirp autogenerates Go code with a server interface and fully functional clients. It's similar to gRPC, but without the custom HTTP server and transport implementations: it runs on the standard library's extremely-well-tested-and-high-performance
net/http Server. It can run on HTTP 1.1, not just http/2, and supports JSON clients for easy integrations across languages
Twirp handles routing and serialization for you in a well-tested, standardized, thoughtful way so you don't have to. Serialization and deserialization code is error-prone and tricky, and you shouldn't be wasting your time deciding whether it should be "POST /friends/:id/new" or "POST /:id/friend" or whatever. Just get to the real work of building services!
Along the way, you get an autogenerated client and a simple, smart framework for passing error messages. Nice!
For more on the motivation behind Twirp (and a comparison to REST APIs and gRPC), the announcement blog post is a good read.
go get to install the Go client-and-server generator:

You will also need:
- protoc, the protobuf compiler. You need version 3+.
- github.com/golang/protobuf/protoc-gen-go, the Go protobuf generator plugin. Get this with
