Haveno UI Proof of Concept

A proof of concept to fetch and render data from Haveno's daemon in ReactJS.

This application is a lightly modified create-react-app with typescript using envoy proxy and grpc-web to use Haveno's gRPC API.

Run in a Browser

1. Run a local Haveno test network, running Alice as a daemon with make alice-daemon.
2. git clone https://github.com/haveno-dex/haveno-ui-poc
3. In a new terminal, start envoy with the config in haveno-ui-poc/config/envoy.yaml (change absolute path for your system): docker run --rm --add-host host.docker.internal:host-gateway -it -v ~/git/haveno-ui-poc/config/envoy.yaml:/envoy.yaml -p 8080:8080 envoyproxy/envoy-dev:8a2143613d43d17d1eb35a24b4a4a4c432215606 -c /envoy.yaml
4. cd haveno-ui-poc
5. npm install
6. npm start to open http://localhost:3000 in a browser
7. Confirm that the Haveno daemon version is displayed (1.6.2)

Run Tests

Running the top-level API tests is a great way to develop and test Haveno end-to-end.

HavenoDaemon provides the interface to the Haveno daemon's gRPC API.

1. Run a local Haveno test network, running Alice and Bob as daemons with make alice-daemon and make bob-daemon.
2. git clone https://github.com/haveno-dex/haveno-ui-poc
3. In a new terminal, start envoy with the config in haveno-ui-poc/config/envoy.test.yaml (change absolute path for your system): docker run --rm --add-host host.docker.internal:host-gateway -it -v ~/git/haveno-ui-poc/config/envoy.test.yaml:/envoy.test.yaml -p 8080:8080 -p 8081:8081 envoyproxy/envoy-dev:8a2143613d43d17d1eb35a24b4a4a4c432215606 -c /envoy.test.yaml
4. In a new terminal, start an instance of monero-wallet-rpc at port 38084. This wallet will be automatically funded in order to fund Alice and Bob during the tests.
   For example: cd ~/git/haveno/.localnet/ && ./monero-wallet-rpc --daemon-address http://localhost:38081 --daemon-login superuser:abctesting123 --stagenet --rpc-bind-port 38084 --rpc-login rpc_user:abc123 --wallet-dir ./ --rpc-access-control-origins http://localhost:8080
5. cd haveno-ui-poc
6. npm install
7. npm test to run all tests or npm run test -- -t 'my test' to run tests by name.

How to Update the Protobuf Client

If the protobuf definitions in haveno-dex/haveno are updated, the typescript imports must be regenerated:

1. Copy grpc.proto and pb.proto from Haveno's protobuf definitions to ./config.
2. Install protobuf for your system, e.g. on mac: brew install protobuf
3. ./bin/build_protobuf.sh
