BlockchainTodoList Application

Pre requirements

1. Ethereum development framework Truffle
2. Local Ethereum blockchain Ganache
3. Web3 provider MetaMask

Start application

Start local blockchain

Run ganache cli, to start a local ethereum blockchain.

Deploy contract

Run truffle deploy to deploy contract on the local blockchain.

Test contract

Run truffle test to test the deployed contract.

Configure MetaMask

1. Change MetaMask network to localhost.
2. Copy a private key from the available list, diplayed by ganache cli.
3. In MetaMask, import a new account with the previously copied private key. Now you have some ETH, and you can interact with the application.

Start angular development server

Run ng serve for a dev server. Navigate to http://localhost:4200/ and connect the MetaMask account to the application.

To use localStorage instead of Ethereum contract, modify the provider definition of TodoListService in app.module.ts to use the correct service class.
