⚠️ Attention
This project is not maintained anymore. And may not work with latest ethereum.

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

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

Part 1

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

Part 2

Open a new terminal and start IPFS daemon with ipfs daemon
Start testrpc in new terminal with testrpc -l 47000000000000.
From inside the project directory run truffle compile to compile your contracts
And truffle migrate to deploy those contracts to the network
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.
Make sure there are no errors in browser console

Login

This project uses your keystore file to login to the application.
For now, the accounts that can login are hardcoded in auth.service.ts with there role. Future builds will feature a screen for proper role and account management.
You can find the keystore for default accounts and there password in 'keys' folder.

URLs

/login
/retailer
/distributor
/manufacturer
/supplier

Todo:

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

Technologies & Languages Used:

Angular4 (Typescript/Javascript)
Truffle (Solidity)
IPFS
Node.js
Express

I can't download things from the Download Report interface.

When I clicked on the download, there was no response. In another interface, the ipfs console encountered an error.
，
what is the problem? Can you tell me specifically how to display your application?

What is the workflow of this project? Cant able to understand

Not able to login.

After navigating to localhost my chrome console shows some error:
ERROR Error: Uncaught (in promise): Error: Contract has not been deployed to detected network (network/artifact mismatch) Error: Contract has not been deployed to detected network (network/artifact mismatch) at contract.js:419 at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invoke (zone.js:391) at Object.onInvoke (core.es5.js:3890) at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invoke (zone.js:390) at Zone.webpackJsonp.../../../../zone.js/dist/zone.js.Zone.run (zone.js:150) at zone.js:889 at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:423) at Object.onInvokeTask (core.es5.js:3881) at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:422) at Zone.webpackJsonp.../../../../zone.js/dist/zone.js.Zone.runTask (zone.js:195) at resolvePromise (zone.js:831) at resolvePromise (zone.js:788) at zone.js:892 at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:423) at Object.onInvokeTask (core.es5.js:3881) at ZoneDelegate.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneDelegate.invokeTask (zone.js:422) at Zone.webpackJsonp.../../../../zone.js/dist/zone.js.Zone.runTask (zone.js:195) at drainMicroTaskQueue (zone.js:601) at ZoneTask.webpackJsonp.../../../../zone.js/dist/zone.js.ZoneTask.invokeTask [as invoke] (zone.js:502) at invokeTask (zone.js:1744)

Am I not able to login because of this error?
Also exactly what files are to uploaded as keystore and password?
Thanks

Report content
