|
|
|
|
## Dependencies
|
|
|
|
- [Rust](https://www.rust-lang.org/tools/install)
|
|
- [wasm-pack](https://rustwasm.github.io/wasm-pack/installer/)

|
|
|
|
## Building
|
|
|
|
```sh
|
|
$ ./build.sh
|
|
```
|
|
|
|
## Running the backend
|
|
|
|
Web browsers currently cannot talk directly to gRPC servers, so it is necessary to run a
|
|
proxy as part of the backend. The `envoy/` subdirectory contains a Dockerfile and config
|
|
file for an Envoy proxy that listens on `localhost:8081` and will route requests to a
|
|
`lightwalletd` frontend listening on `localhost:9067`.
|
|
|
|
See [the `lightwalletd` documentation](https://github.com/zcash-hackworks/lightwalletd)
|
|
for details on how to set up a local `lightwalletd` testnet instance. Note that when
|
|
starting the frontend, you may need to use `--bind-addr 0.0.0.0:9067` so that the Docker
|
|
container can access it.
|
|
|
|
To build and run the Envoy proxy:
|
|
|
|
```sh
|
|
$ docker build -t lightwalletd/envoy -f envoy/envoy.Dockerfile envoy
|
|
$ docker run -d -p 8081:8081 --network=host lightwalletd/envoy
|
|
```
|
|
|
|
## Running the demo
|
|
|
|
```sh
|
|
$ cd demo-www
|
|
$ npm run start
|
|
```
|
|
|
|
Then open http://localhost:8080/ in your browser.
