An experimental library to enable gRPC tunnelling over a WebSocket.
This is work in progress and requires a patched tonic. See
Cargo.toml for the patches.
We would like to use gRPC in browsers that do not support bare TCP connections and HTTP/2. For that, we use WebSockets to emulate TCP and use HTTP/2 implementation from tonic/hyper/h2. This is especially useful for streaming gRPC. Note that gRPC-web does not support client to server streaming: grpc/grpc-web#815.
Run server example in native environment:
cargo run --bin server
Then compile wasm and open it in browser:
cd examples/wasm-client
wasm-pack --target web
python3 -m http.server
// open http://0.0.0.0:8000/ in browser
