Hyperledger - Fabric - NodeJS - Angular

This is a sample solution having multiple layers and modified after forked from fabric-samples/fabcar

Here assumption is that you have installed all prerequisites that a standard Hyperledger Fabric requires.

We have three folders for three different layers

HLF

this folder contains all Fabric related cryptographic material, channel, genesis block and chaincode.

Fabcar

this is web server based on nodejs and expressjs. facilitates following things.

• Acts as client for Fabric network by using Fabric-Client sdk
• Acts like a web server that wraps all the fabric interaction logic as REST API (GET, POST endpoints).
• Bridge between a user interface layer and fabric network layer.

FabCarClient

This is end user interface developed using Angular 7. This consumes REST api to contact with fabcar web server.

Start Fabric

Run following commands in fabcar folder to start network, install dependencies, enroll admin and register user.

cd fabcar

./startFabric.sh

npm install

node enrollAdmin.js

node registerUser.js

Start Web server

Run following commands in fabcar folder to start the web server

node app.js

Set up User interface

Open another terminal and run following commands in FabCarClient folder to start the user interface application.

cd FabCarClient

npm install -g @angular/cli

npm install

ng serve

After completion of above commands. open any web browser and follow this link http://localhost:4200

Stop the network

To stop network after testing, run the given commands in HLF folder

cd HLF

./stop.sh

Kill the network

To kill the complete network, use the ./teardown.sh in HLF folder

cd HLF

./teardown.sh

Thank you.
