Installing developer environment for hyperledger fabric (Refer- https://hyperledger.github.io/composer/latest/installing/development-tools.html)
- Essential CLI tools:
$ npm install -g composer-cli@0.19
- Utility for running a REST Server on your machine to expose your business networks as RESTful APIs:
$ npm install -g composer-rest-server@0.19
- Useful utility for generating application assets:
$ npm install -g generator-hyperledger-composer@0.19
- Yeoman is a tool for generating applications, which utilises generator-hyperledger-composer:
$ npm install -g yo
Install Playground: Browser app for simple editing and testing Business Networks
$ npm install -g composer-playground
Install Hyperledger Fabric
This step gives you a local Hyperledger Fabric runtime to deploy your business networks to.
In a directory of your choice (we will assume ~/fabric-dev-servers), get the .tar.gz file that contains the tools to install Hyperledger Fabric:
$ mkdir ~/fabric-dev-servers && cd ~/fabric-dev-servers
$ curl -O https://raw.githubusercontent.com/hyperledger/composer-tools/master/packages/fabric-dev-servers/fabric-dev-servers.tar.gz
$ tar -xvf fabric-dev-servers.tar.gz
A zip is also available if you prefer: just replace the .tar.gz file with fabric-dev-servers.zip and the tar -xvf command with a unzip command in the preceding snippet.
Use the scripts you just downloaded and extracted to download a local Hyperledger Fabric v1.1 runtime:
$ cd ~/fabric-dev-servers
$ export FABRIC_VERSION=hlfv11
$ ./downloadFabric.sh
Install Python Packages for Recommendation System
$ pip3 install -r requirements.txt
Starting and stopping Hyperledger Fabric
The first time you start up a new runtime, you'll need to run the start script, then generate a PeerAdmin card:
$ cd ~/fabric-dev-servers
$ export FABRIC_VERSION=hlfv11
$ ./startFabric.sh
$ ./createPeerAdminCard.sh
You can start and stop your runtime using ~/fabric-dev-servers/stopFabric.sh, and start it again with ~/fabric-dev-servers/startFabric.sh.
At the end of your development session, you run ~/fabric-dev-servers/stopFabric.sh and then ~/fabric-dev-servers/teardownFabric.sh.
Starting composer-playground
$ composer-playground
It will typically open your browser automatically, at the following address: http://localhost:8080/login
Running web application (Refer - https://hyperledger.github.io/composer/v0.19/applications/web)
- First start hyperledger fabric runtime by above commands
$ cd ~/fabric-dev-servers<br>
$ ./startFabric.sh
$ ./createPeerAdminCard.sh
- Install the Business Network Archive onto the Hyperledger Fabric network
$ composer network install --card PeerAdmin@hlfv1 --archiveFile healthcare_blockchain@0.0.1.bna
- Start your Business Network on your Hyperledger Fabric
$ composer network start --networkName healthcare_blockchain --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card
- Install the 'admin' card ready for use
$ composer card import --file networkadmin.card
- Deploy composer-rest-server
$ composer-rest-server -c admin@healthcare_blockchain -n never -u true -d Y
- Running the node app locally
$ node app.js
- Now open index.html, you will have to provide your id and userType (patient or doctor).
- Various html pages are provided corresponding to different transactions (inferred from fileName).
