Smart Contracts & Hyperledger Fabric: Hyperledger Fabric Web App

Examine steps involved in building a JavaScript web application that interacts with a smart contract deployed to a Hyperledger Fabric network in your Blockchain solutions. In this course participants use NodeJS to code an application to create an admin user for an organization connected to a Fabric network. You will write an application in NodeJS that uses admin credentials to provision the application user. Learn how to develop a NodeJS application that retrieves an instance of a smart contract deployed to a Fabric network and invoke query applications on it. In building the backend of the Fabric web app create a NodeJS application able to invoke queries and transactions against chaincode deployed to Hyperledger Fabric. Then build a web UI enabling both queries and transactions against a smart contract by connecting to the previously created backend app. Test the app by verifying features implemented by accessing the UI and invoking queries and transactions. The closing exercise uses a Gateway instance to retrieve chaincode from a Fabric network and uses a contract instance to perform read and write operations.
