node-red-contrib-hyperledger-composer

A set of nodes for interacting with Hyperledger Composer

Note : These node will only work if you are running node red locally. It won't work if you are using node red on bluemix.

Hyperledger-Composer-Out

A node red output node that allows you to create or update assets or participants and submit transactions.

Example Usage

This example uses the Car Auction Sample Network that can be obtained from here

The Car Auction Sample, simulates a car auction. It has two kinds of participant. An Auctioneer, who is responsible for conducting the auction, and a member who can bid on cars in the auction. In this example we will create a participant, the participant .

  1. Deploy the Car Auction Sample Network using the playground or on the command line (If you don't know how to do this go here)

  2. Create a hyperledger-composer-out node

  3. Enter the connection profile name, business network identifier, participant Id, and participant password on the hyperledger-composer-out node.

  4. Use an inject node and set it to use JSON and enter the following JSON

{"$class": "org.acme.vehicle.auction.Member",   "balance": 1234,   "email": "Joe-Blogs@org.acme.com",   "firstName": "Joe",   "lastName": "Blogs" }
  1. Using the playground or command line you should now be able to see the participant that has been created.

Hyperledger-Composer-Mid

A node red mid flow node that allows you to get assets or participants from a registry.

Example Usage

This example follows on from the above example. It will retrieve the participant that was created above.

  1. Create a hyperledger-composer-mid node

  2. Enter the connection profile name, business network identifier, participant Id, and participant password on the hyperledger-composer-mid node.

  3. Use an inject node and set it to use JSON and enter the following JSON

{"modelName" : "org.acme.vehicle.auction.Member", "id" : "Joe-Blogs@org.acme.com"}
  1. Use a debug node to capture the output from the hyperledger-composer-mid node

Hyperledger-Composer-In

A node red input node that subscribes to events from a blockchain
