Hyperledger Fabric Gateway Client API for Node
The Fabric Gateway client API allows applications to interact with a Hyperledger Fabric blockchain network. It implements the Fabric programming model, providing a simple API to submit transactions to a ledger or query the contents of a ledger with minimal code.
How to use
Samples showing how to create client applications that connect to and interact with a Hyperledger Fabric network, are available in the fabric-samples repository:
- asset-transfer-basic for examples of transaction submit and evaluate.
- asset-transfer-events for examples of chaincode eventing.
- off_chain_data for examples of block eventing.
