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](https://developers.google.com/protocol-buffers/docs/proto3) file and
then Twirp autogenerates Go code with a server interface and fully functional
clients. It's similar to [gRPC](http://www.grpc.io/), 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!
