The WASM binary doubles in size to 2MB after this change. This is still dwarfed by the size of the spend parameters (46MB), and transaction creation time decreases by 20% in exchange.

Dependencies
Building
$ ./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
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:
$ docker build -t lightwalletd/envoy -f envoy/envoy.Dockerfile envoy
$ docker run -d -p 8081:8081 --network=host lightwalletd/envoy
Running the demo
$ ln -s "$HOME/.zcash-params" demo-www/params
$ cd demo-www
$ npm run start
Then open http://localhost:8080/ in your browser.
