Flogo extension for Hyperledger Fabric client

This Flogo extension is designed to allow delopers to use the zero-code visual programming environment of the TIBCO Flogo® Enterprise to design and implement apps or services that interact with Hyperledger Fabric networks. This extension supports the following release versions:

• TIBCO Flogo® Enterprise 2.4
• Hyperledger Fabric 1.4
• Hyperledger Fabric Go SDK v1.0.0-alpha5

The Fabric Connector allows you to configure the target fabric network used by the app.

It supports the following activity for submitting an invoke or query request to a Hyperledger Fabric network.

• Fabric Request: It sends a fabric invoke request to execute a specified chaincode that inserts or updates records in the distributed ledger or private collections. It sends a fabric query request to execute a specified chaincode that queries the records in the distributed ledger or private collections without changing any state.

More activities can be added to integrate with blockchain events.

With these extensions, Hyperledger Fabric client apps can be designed and implemented with zero code. Refer to the sample marble-client for more details of a REST service implemented by using TIBCO Flogo® Enterprise that updates and retrieves data on a distributed ledger of Hyperledger Fabric.

This extension is packaged as fabclientExtension.zip, which can be re-created from source by using the script zip-fabclient.sh. You can upload the zip-file to the TIBCO Flogo® Enterprise as an extension, and start using the connector and activities.
