Usage instructions

Prerequisites

  • Node 8.16.0

Install required packages by running: npm i -g [email protected] [email protected] [email protected]

Optionally install VS Code extension Hyperledger Composer

Crete a network

Inside the fabric-scripts directory, execute the following steps

  • Download Fabric images: ./downloadFabric.sh
  • Run the start script: ./startFabric.sh. This will
    • Start the downloaded Fabric images
    • Create a channel named composerchannel
    • Join the peer to that channel

You can stop or destroy the containers by running ./stopFabric.sh or ./teardownFabric.sh

Initiate the Composer environment

Create and import the Administrator credentials (Business Network Card)

Make sure no data from previous Composer installations is present rm -rf ~/.composer

  • Inside the fabric-scripts directory run ./createPeerAdminCard.sh

    • You can list existing BNCs with composer card list

  • Generate the business network archive (.bna or banana file) by running the following inside the root application directory composer archive create -t dir -n .

  • Install the generated archive ([email protected]) with the Admin credentials: composer network install --card PeerAdmin@hlfv1 --archiveFile [email protected]

  • Start the installed network composer network start --networkName fishy-network --networkVersion 0.0.1 --card PeerAdmin@hlfv1 --networkAdmin admin --networkAdminEnrollSecret adminpw

    This will generate the Business Network card which can be imported into the playground. You can run the playground client locally with composer-playground

  • Start the REST server composer-rest-server -p 5000 -c admin@fishy-network -n always
