Spydra Hyperledger Fabric Base Contract

The Spydra Hyperledger Fabric Base Contract has various utility methods which provide additional functionalities out of the box to any Chaincode that is deployed in a Spydra blockchain network. Simply extend your own Chaincode Smart Contract from the Spydra Base Contract to get these additional features.

  • Query the world state using Graph QL. For more details, refer to Spydra Graph QL.

Quick Start

  1. Install spydra-fabric-contract-node from npm.

    With npm:

    $ npm install --save spydra-fabric-contract-node

    or using yarn:

    $ yarn add spydra-fabric-contract-node

  2. Extend your Smart Contract from the Spydra Base Contract.

    class MyCustomContract extends SpydraContract {
    
}

  3. Export the SpydraContract as one of the Smart contracts in index.js.

        module.exports.contracts = [MyCustomContract, SpydraContract];

  4. Deploy the Chaincode on a Spydra Blockchain network and start querying on any attribute using Graph QL.
