Top 23 TypeScript Grpc Projects
-
insomnia
The open-source, cross-platform API client for GraphQL, REST, WebSockets, SSE and gRPC. With Cloud, Local and Git storage.
To send the message, you’ll want an HTTP tooling client that makes it easy to send POST requests - I’ve opted for Kong’s Insomnia but you could also use Postman or even a raw cURL request.

Project mention: Real-Time Data with gRPC Streaming: .NET & React with Connect RPC | dev.to | 2025-07-05
Instead of using the standard gRPC JavaScript library (grpc-web), which hasn’t been updated in almost two years, I opted for the Connect RPC implementation. Connect RPC offers a modern, robust, and developer-friendly experience for gRPC in the browser, making it easy to consume streaming endpoints and integrate them seamlessly into React components.
