Hyperledger Composer nodes for node-red

npm install node-red-contrib-composer

#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, update or delete 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. On Composer Card click the pencil top add a new config node. Specify the card name, or use the drop down to use one previous created.

  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": "[email protected]",   "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 create, retrieve, update, or delete assets and 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. On Composer Card click the pencil top add a new config node. Specify the card name, or use the drop down to use one previous created.

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

    {"modelName" : "org.acme.vehicle.auction.Member", "id" : "[email protected]"}
    
  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

  1. On Composer Card click the pencil top add a new config node. Specify the card name, or use the drop down to use one previous created.
