Скачать или смотреть Hyperledger Fabric Node SDK Setup & Admin Registration - Chapter 13

In this chapter, we set up the Node.js SDK for our Hyperledger Fabric project and prepare it for interacting with the deployed chaincode. We remove old scripts, clean the wallet, create a proper folder structure, and build fresh admin registration scripts for Government (Org2) and NGO (Org3). Finally, we start the network, add Org3, and test our setup.

Topics Covered:
• Cleaning old Node SDK files (wallet, scripts)
• Creating app.js, routes, controllers, services
• Writing fabricService.js for registering users/admins
• Creating Government Admin & NGO Admin certificates
• Starting Fabric network & adding Org3
• Fixing common "peer failed to join channel" issue
