How to use

There are 2 small parts to successfully running this project.

Part 1

  1. git clone https://github.com/jakubbares/truffle-demo
  2. cd truffle-demo
  3. npm install

Part 2

Truffle: Install Truffle "npm install -g truffle"

Blockchain: For the second part, be sure you're connected to an Ethereum client before running the commands below. If you're new, install testrpc "npm install -g ethereumjs-testrpc" (https://github.com/ethereumjs/testrpc) to run a local blockchain RPC server. After that, simply run testrpc in a new tab.

And then in the original tab, run:

  1. truffle compile to compile your contracts
  2. truffle migrate to deploy those contracts to the network
  3. ng serve. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
  4. Make sure there are no errors in browser console

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive/pipe/service/class/module.

Build

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.

Running unit tests

  1. Run ng test to execute the unit tests via Karma.
  2. Run truffle test to run tests associated with your solidity smart contracts. The test folder for this can be found in the test directory at the root level of this project

Running end-to-end tests

Run ng e2e to execute the end-to-end tests via Protractor. Before running the tests make sure you are serving the app via ng serve.
