This guide will walk you through the steps to set up and run a Fabric application. Follow the instructions below to clone the repository, set up the network, deploy the chaincode, and run the application.

• Ensure you have the necessary dependencies installed, including Node.js, npm, Docker, and Docker Compose.

1. Navigate to the Fabric Samples Folder

   cd fabric-samples

2. Clone the Repository

   git clone <repository-url>

3. Change Directory to the Fabric Application

   cd fabric-app

4. Folder Structure

   In the fabric-app directory, you will find two folders:

   1. chaincode
   2. application

5. Set Up Chaincode

   Change directory to the chaincode folder:

   cd chaincode

   Install the necessary Node modules:

   npm install

   Run the following commands to set environment variables:

   export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp
   export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
   export CORE_PEER_LOCALMSPID="Org1MSP"

6. Open a New Terminal Session

   In the new terminal session, navigate to the test network directory:

   cd fabric-samples/test-network

7. Shut Down Any Running Network

   sudo ./network.sh down

8. Create a New Channel

   ./network.sh up createChannel -c mychannel -ca

9. Deploy the Chaincode

   ./network.sh deployCC -ccn basic -ccp ../fabric-app/chaincode/ -ccl javascript

10. Return to the Previous Terminal Session

    Navigate to the application folder:

    cd ../application

11. Install Node Modules

    npm install

12. Run the Application

    node app.js

Your Fabric application should now be up and running. Follow the steps carefully, and ensure all dependencies are installed before starting the setup process. If you encounter any issues, refer to the Fabric documentation or seek help from the community.
