Get the source code of this from the PacktPub GitHub repository if you haven’t already done so. Once you download the source code, navigate to the directory blockchain-by-example/fsc-restful. The example we will run here is based on a Fabric sample project, located at github: https://github.com/hyperledger/fabric-samples.

To run the web application shipped with the book's code, we first need to bring up the Fabric network. We make sure that no other active container is running by using: 

sudo ./script.sh –m down

Then, clear any unused networks:

docker network prune

Navigate to the webapp/ folder and run:

npm install

You'll have to wait for npm to install a few packages. Once the operation is successfully finished, navigate back to the fsc-restful folder, and launch the Fabric network by running:

sudo ./script –m up 

Install the Chaincode, and instantiate it with initial customer order data, before invoking createRowfoodChaincode:

peer Chaincode install -n fsccc -v 1.0 -p "$CC_SRC_PATH" -l "$LANGUAGE"
peer Chaincode instantiate -o orderer.example.com:7050 -C mychannel -n fsccc -l "$LANGUAGE" -v 1.0 -c '{"Args":["init","order_001","John_1","100","5"]}'
peer Chaincode invoke -o orderer.example.com:7050 -C mychannel -n fsccc -c '{"Args":["createRawFood","order_001"]}'
