Groa

Express gRPC middleware framework for Node.js that provides a Koa 2-style middleware system and API. Current stable version is 0.0.15. It supports async/await based middleware, bidirectional streaming, and a built-in status code system. Key differentiators include familiar Koa-like context and middleware pattern, built-in proto loading, and streaming support. Release cadence is irregular. Requires Node.js v7.6+.
