gRPC-Web-Websocket Example: A simple Golang API server and TypeScript frontend

Get started with HTTP 1.1 and WebSockets with both Client and Server side streaming

Makes use fo the gRPC Web library at https://github.com/improbable-eng/

• npm install
• npm start to start the Golang server and Webpack dev server
• Go to http://localhost:8081

The example program implements a Ping() with client side streaming and a Pong() with server side streaming

• Pong() sends every 1ms the current unix nanosecond timestamp (1000 times)
• The ts browser client echos back each Pong() stream message it receives through its Ping() stream
• once the Pong() stream terminates, the ts client terminates its Ping() stream
• finally the Ping() method echoes back the average round-trip latency in nanoseconds
• result is printed both on client and server side
