Basic implementation of a front end framework for a Solidity smart contract built for the Ethereum blockchain.

How to run full stack (web + blockchain) application

Linux Instructions

Ganache setup

1. Start Ganache on 127.0.0.1:7545 (Ganache should shart at this network address by default). This starts up the local Ganace chain.
2. Open a truffle console by envoking sudo truffle console --network development from the counterDapp/ directory. This opens a truffle console with a connection to the Ganache chain.
3. Execute compile in the truffle console.
4. Execute migrate in the truffle console. This deploys the Counter.sol smart contract on the Ganace chain.

• If you see this error when migrating: Error: Returned values aren't valid, did it run Out of Gas?, navigate to the build/contracts directory and remove the .json files in there ('sudo rm *'). Re-compile and migrate afterwards.

Start the web application

1. Navigate to src/.
2. Install all node dependencies by executing npm install.
3. Execute npm start to start the web application on localhost:8080 (modifiable by editing app.js).

Windows Instructions

1. Install Linux.
2. Follow Linux instructions above.
