Hyperledger Fabric NodeSDK Tester

Node sdk test examples to interact with bityoga fabric set up

Requirements

1. Bityoga fabric sdk should be up and running
2. Node version
   • Supports node version >=8
   • Tested with v8.9.0

Run Instructions

1. Clone this repository

   git clone https://github.com/bityoga/fabric_node_sdk_tester.git

2. Run npm install

   • cd fabric_node_sdk_tester
   • Set node version: nvm use node v8.9.0 (using nvm)
   • npm install

3. Update ip address in 'network_profile.json'

   • update the url ip addresses of orderer, peer2, orgca, tlsca (4 places).
   • update it with your prime manager's ip address

4. Retrieve hyperledger fabric tls certificates of 'orderer' and 'peer2'

   (Replace ip address with your fabric prime manager's ip address)

   scp -r root@LOCALHOST_OR_YOUR_MASTER_MACHINE_IP_ADDRESS:/root/hlft-store/tlsca/orderer/tls-msp/tlscacerts/tls-tlsca-7054.pem ./hlft-store/tlsca/orderer/tls-msp/tlscacerts/tls-tlsca-7054.pem
   

   scp -r root@LOCALHOST_OR_YOUR_MASTER_MACHINE_IP_ADDRESS:/root/hlft-store/tlsca/peer2/tls-msp/tlscacerts/tls-tlsca-7054.pem ./hlft-store/tlsca/peer2/tls-msp/tlscacerts/tls-tlsca-7054.pem
   

   (Or run shell script)

   bash get_tls_certificates.sh

5. Enroll admin

   Command : node enrollAdmin.js

   • check wallet directory
   • a directory named 'admin' will be available.
   • certificates for admin will be available under this directory.

6. Register user

   If needed, edit the following lines in registerUser.js

   const user_name = "lion";
   const user_password = "lion";
   const user_role = "client";

   Command : node registerUser.js

   • check wallet directory
   • a directory with the name of the 'registerd user name' will be available
   • certificates for the registerd user will be available under this directory.

7. Query a chaincode

   If needed, edit the following lines in query.js

     const user_name = "lion";
     const CHANNEL_NAME  = "appchannel";
     const CHAIN_CODE_NAME = "carcc";
     const CHAIN_CODE_FUNCTION_NAME = "listCars";
     const result = await contract.evaluateTransaction(CHAIN_CODE_FUNCTION_NAME);
     const result = await contract.evaluateTransaction(CHAIN_CODE_FUNCTION_NAME,"b");

   Command : node query.js

8. Invoke a chaincode

   If needed, edit the following lines in invoke.js

     const user_name = "lion";
     const CHANNEL_NAME  = "appchannel";
     const CHAIN_CODE_NAME = "carcc";
     const CHAIN_CODE_FUNCTION_NAME = "createCar";
     await contract.submitTransaction(CHAIN_CODE_FUNCTION_NAME, "TR8800","Opel","Corsa","Light Blue","7","2050","1");
     await contract.submitTransaction(CHAIN_CODE_FUNCTION_NAME, "b","a","1");

   Command : node invoke.js
