Now that you have succeeded in modeling your first business network and deployed it to the Hyperledger Fabric, let’s explore the REST API interfaces of a model and build a Node-RED Dashboard web application to exercise the underlying Blockchain. Node-RED is a visual programming tool that can quickly wire together applications. This live code demo will showcase a Hurricane Storm Network running on an IBM Blockchain Platform Hyperledger Fabric. This week’s session will hack the Composer Playground Explorer and construct a Node-RED Dashboard that calls the Hyperledger Composer REST APIs.

  1. Hi John,
    where can we get access to the basic-storm-network model ?
    Thx, Herve

    Hey Herve – There are a bunch of example BNA implementations here – https://github.com/hyperledger/composer-sample-networks/tree/v0.16.x/packages
    I thought you would be able to grab the storm-netwoork code there but I don’t see a link.

    • Hey John, I had looked up composer-sample-* before reaching out 😉
      Do you intend to commit basic-storm-network model there soon?

      Hi John,
      I’m new in Hyperledger Composer and Node.Red. I was impressed when I saw your presentation. In my opinion it is very helpful to use Node-Red with a dasboard for rapid prototyping for business purposes and presentations too. So is it possible to get the BNA file to study the implementation? Unfortunately It’s not available at composer-sample-networks area. Thx in advance Rainer
