Supply chain management on blockchain using Angular 4 + Truffle + IPFS + Ethereum

## How to use
There are 2 small parts to successfully running this project.

### Prerequisite

1. Node.js
2. IPFS
3. Truffle Framework (`npm install -g truffle` or on linux `sudo npm install -g truffle`)
4. Testrpc (`npm install -g ethereumjs-testrpc` or on linux `sudo npm install -g ethereumjs-testrpc`)

### Part 1

1. `git clone https://github.com/shekhar-shubhendu/supply-chain.git`
2. `cd supply-chain`
3. `npm install`
4. `npm install -g @angular/cli@latest`
(linux users might have to do: `sudo npm install -g @angular/cli@latest`)

### Part 2

4. Open a new terminal and start IPFS daemon with `ipfs daemon`
6. Start testrpc in new terminal with `testrpc -l 47000000000000`.
7. From inside the project directory run `truffle compile` to compile your contracts
8. And `truffle migrate` to deploy those contracts to the network
9. Now finally, start the project with `npm start`. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
10. Make sure there are no errors in browser console

2. `/retailer`
3. `/distributor`

### Todo:

1. Access IPFS from browser (Remove separate script for IPFS upload).
