Usage instructions

Prerequisites

• Node 8.16.0

Install required packages by running: npm i -g composer-cli@0.20 composer-rest-server@0.20 composer-playground@0.20

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 (fishy-network@0.0.1.bna) with the Admin credentials: composer network install --card PeerAdmin@hlfv1 --archiveFile fishy-network@0.0.1.bna

• 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
