In order to build and run the frontend code LOCALLY, run

1. yarn install or npm install depending on your preference
2. make sure you have testrpc running , and change truffle.js to point to that network. e.g. localhost:8545.
3. truffle compile to create the json contract artifacts
4. truffle migrate to deploy the contracts onto the network
5. change the web3 provider in app/main.js to point to the testrpc server.
6. npm run build to compile the javascript and html assets into the build folder
7. truffle serve to serve the assets in the build folder
8. navigate to the host and port that truffle is serving (default, localhost:8080) in order to see the served assets

In order to build and run the frontend code IN DOCKER, run

1. docker-compose -f docker/docker-compose.yml up -d
2. once the container starts, find the hash of the truffle3_container service and run docker attach <hash>
3. yarn install or npm install depending on your preference
4. change truffle.js to point to that network. this is testrpc:8545 from inside the container
5. truffle compile to create the json contract artifacts
6. truffle migrate to deploy the contracts onto the network
7. change the web3 provider in app/main.js to point to the testrpc server. !! this will be localhost:7000 !!
8. npm run build to compile the javascript and html assets into the build folder
9. truffle serve to serve the assets in the build folder
10. navigate to localhost:7001/index.html in your browser to see the served assets

Possible upgrades

• Use the webpack hotloader to sense when contracts or javascript have been recompiled and rebuild the application
