Truffle – Pulsenet

Using Truffle

Development environment set up

Before we start, you will require the following technical specifications.

Windows, Linux or Mac OS X
Node.js v8.9.4 LTS or later
Git

Windows
Truffle when running on Windows may encounter some naming conflicts that could prevent Truffle from executing properly. Please see the section on resolving naming conflicts for solutions.

Installation

We only need one command to install Truffle:

				
					npm install -g truffle

Truffle installation can be checked by typing truffle version on a terminal. If you see an error, check that your npm modules are added to your path.

Creating A Project

Step for a developer to create a Truffle project. We’ll use the *PulseFloki as an example, which creates a token that can be transferred between accounts:

Create a new directory for your Truffle project

				
					mkdir MegaCoin
cd MegaCoin

Intialize your project:

				
					truffle init

Once this operation is completed, you’ll now have a project structure with the following items:

contracts/: Directory for Solidity contracts
migrations/: Directory for scriptable deployment files
test/: Directory for test files for testing your application and contracts
truffle-config.js: Truffle configuration file

Creating the Contract

Developers can write their own smart contract or download the PRC20 token smart contract template.

Compiling the Contract

To compile a Truffle project, change to the root of the directory in which the project is located, then type the following into a terminal:

				
					truffle compile

Config Truffle for TC

Go to truffle-config.js
Update the truffle-config with nc-network-crendentials.

Please note, it requires mnemonic to be passed in for Provider, this is the seed phrase for the account you’d like to deploy from, for instance the account in your Metamask wallet. Create a new .secret file in root directory and then enter your 12 word mnemonic seed phrase to get started. To reveal the seed words from metamask wallet you can go to Metamask Settings, then from the menu choose Security and Privacy where you will see a button that says reveal seed words.

Deploying on PULSE Network

Run this command in root of the project directory:

				
					$ truffle migrate --network testnet

Contract will be deployed on PulseNet Chain Chapel Testnet, it look like this:

				
					1_initial_migration.js
