grpc-xhr

A lightweight JavaScript library for making AJAX requests to gRPC-web or gRPC Gateway endpoints from the browser. Current stable version is 1.0.13 with low release cadence (last release 2023). Provides a simple Promise-based interface for streaming and unary gRPC calls over XHR, without requiring gRPC-web or a service worker. Smaller bundle size compared to gRPC-web client, but limited to browser environments and lacks advanced features like client-side interceptors or metadata manipulation.
