Structure of this repo

folder chaincode contains chaincode (i.e. smart contract logic)
folder supplychain contains the client code to use the smart contract
- folder supplychain/typescript contains the client code in typescript
- folder supplychain/app contains the web app in flask to use the smart contract
folder first-network contains the basic network configuration for our application (taken from the fabric-samples repo)

Starting the application

run ./teardownAll.sh (if you already used it in the past)
run ./startFabric.sh (this may take a few minutes and will compile the chaincode and start the network and also to compile the client code and bootstrap a local wallet)
run ./runWebApp.sh (this will launch the web server)
run ./launchBrowser (opens a browser with a tab for one farmer (F0), one shipper (S0) and the evaluator)

To compile the client code again you can run npm run build from supplychain/typescript.

When creating a new app/contract you can (and possibly should) change the "supplychain" string by:

editing {.,chaincode}/supplychain/typescript/package.json and replacing the "name" field
changing CONTRACT_NAME in contractConfig.sh
change contractName and directory in the beginning of supplychain/typescript/src/client.ts
renaming folders {.,chaincode}/supplychain;
changing class/type names wherever you find it appropriate
