Connect-Gateway

The Connect-Gateway introduces direct binding from gRPC-Gateway local handlers to Connect service handlers. It addresses the recurring request to support Google API HTTP annotations in Connect:

• Service option for Connect HTTP path #468
• google.api.Http annotation support #274

We provide a complete solution for the two to communicate seamlessly through simple function calls, without relying on network communications. All of which is done by reusing as much of the code from both projects as possible and mimicking the connect-go implementation, i.e. reducing code generation as much as possible, with most of the logic being provided in a library.

Features

• Unary calls support
• Connect interceptors support
• Bidirectional gRPC metadata transmission
• Connect errors to gRPC errors convertion

Limitations

• No support for streaming calls as it is not yet supported by the gRPC-Gateway's "in-process" transport mode
• Uninitialized Request.Peer and Request.Spec properties on Connect requests as it cannot be set externally
