Install, Compile, Test and Deploy Truffle Project on Ganache Network (via Truffle CLI) or Sepolia Network (via Truffle Dashboard)

1. Installation of Truffle

• a. On Ubuntu
• b. On Windows

2. Create or Unbox a Truffle project

• a. Unbox an existing Truffle Project
• b. Create a bare Truffle Project

3. Compile a Truffle Project

4. Test the Smart Contracts in Truffle Project

5. Deploy the Truffle Project

• a. Deploy via Truffle Command Line Interface
• b. Deploy via Truffle Dashboard

==============================================

Step - 1: Installation of Truffle

a. On Ubuntu 22.04 LTS

• Follow the steps to install Truffle as per the tutorial

b. On Windows

1. Install Nodejs

• Go to Nodejs website and download the stable version.

2. Install Truffle

• On the command prompt, check the version of nodejs node -v

• Check the version of nvm npm -v

• Type : npm install -g truffle

• Check the version of Truffle truffle version

• To install Ganachenpm install -g ganache

3. Install VS Code

• Go to the Visual Studio Code and download the Windows version

4. Add Solidity extension on VS

Step - 2: Create or Unbox a Truffle project

(a). Unbox an existing Truffle Project - MetaCoin

• On the Terminal : mkdir MetaCoin
• Go to the folder: cd MetaCoin
• Unbox the Truffle Project : truffle unbox metacoin

(b) To create a bare project that doesn’t come with any smart contract or boilerplate code, type: truffle init

• The following directory structure is created :

.
├── contracts           <-- solidity contracts live here
├── migrations          <-- migration scripts live here
├── test                <-- tests (Solidity and JS) live here
└── truffle-config.js   <-- truffle configuration file

Step - 3 : Compile a Truffle Project

• On the VS Terminal : truffle compile

• To resolve this issue run the following commands on the VS Terminal

set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Get-ExecutionPolicy

Get-ExecutionPolicy -list

• This command generates .json files corresponding to each Smart Contract.

Step - 4 : Test the Smart Contracts

• The test files are saved in the folder, test with an extension .js
• For the sample project created the file name : metacoin.js

• Run the Command : truffle test

Step - 5 : Deploy Truffle Project

a: Deploying the Smart Contract via Truffle Command Line Interface

• In the Project folder there is a configuration file : truffle-config.js.
• In this file uncomment the development network parameters and set the port number as 7545 as shown below

• Start the Ganache Environment.
• Select a new Workspace and name: Metacoin
• Add the Project configuration file: truffle-config.js

• Type the command : truffle migrate --reset

• On the Ganache Environment - Account Tab: 5 transactions are reported corresponding to the deployment

• On the Ganache Environment - Blocks tab, 5 blocks are created in the Ganache environment

• On the Ganache Environment - Transactions Tab: Contract creation details are listed

• On the Ganache Environment - Contracts Tab: Contract deployment details are listed

• On Ganache Environment - Events Tab: Contract registered event is reported

b: Deploy via Truffle Dashboard

1. Run the command truffle dashboard on the VSCode Terminal

• Truffle Dashboard is running on http://localhost:24012/rpc

2. Login to the Metamask Wallet and select the Network as Sepolia Testnet

3. Run the commnad truffle migrate --network dashboard

• This command starts to deploy the smart contract : ConvertLib.sol
• On the Truffle Dashboard, there will be a prompt to confirm the deployment of the smart Contract : ConvertLib.sol
• Click the Confirm button

• Metamask extension will popup for confirmation.
• Click the Confirm button

• The status of the transaction is displayed on the Metamask popup window

• Next the migrate command starts to deploy the smart contract : MetaCoin.sol
• On the Truffle Dashboard, there will be a prompt to confirm the deployment of the smart Contract : MetaCoin.sol
• Click the Confirm button

• Metamask extension will popup for confirmation.
• Click the Confirm button

• The status of the transaction is displayed on the Metamask popup window

• Deployment details on the VScode Terminal as follows:

• The transacrion details are displayed on Etherscan.io : Sepolia Testnet
