Using Truffle

Truffle is a development environment, testing framework and asset pipeline for Ethereum, aiming to make life as an Ethereum developer easier.
Adding Truffle to your project
You'll need Node.js v8+ installed before we get started. And you can choose a preferred package management tool to begin with:
npm
Yarn
# To use truffle locally in your project, you must init a package.json file
$ npm init
​
# Install truffle and wallet-provider to your project
$ npm i -D truffle @truffle/hdwallet-provider
​
# Generate truffle configuation file and default folders
$ npm exec -- truffle init
# To use truffle locally in your project, you must init a package.json file
$ yarn init
​
# Install truffle and wallet-provider to your project
$ yarn add --dev truffle @truffle/hdwallet-provider
​
# Generate truffle configuation file and default folders
$ yarn truffle init
You can install global Truffle to your environment:
$ npm i -g truffle
Then, you can ignore npm exec -- or yarn commands before truffle
Setup Truffle config file
We are going to edit truffle-config.js. First, we uncomment this line to import @truffle/hdwallet-provider:
truffle-config.js
- // const HDWalletProvider = require('@truffle/hdwallet-provider');
+ const HDWalletProvider = require('@truffle/hdwallet-provider');
Then, we add ThunderCore network settings into your project.
truffle-config.js
  networks: {
+   "thunder-mainnet": {
+     provider: () => new HDWalletProvider([process.env.KEY], "https://mainnet-rpc.thundercore.com"),
+     network_id: "108",
+     gas: 90000000,
+     gasPrice: 1e9
+   },
+   "thunder-testnet": {
+     provider: () => new HDWalletProvider([process.env.KEY], "https://testnet-rpc.thundercore.com"),
+     network_id: "18",
+     gas: 90000000,
+     gasPrice: 1e9
+   }
  }
Never store your private key directly in truffle-config.js
Deploy a Contract
You'll need gas tokens to deploy contracts. To test on ThunderCore testnet, you can get testnet tokens from ThunderCore testnet Faucet​
Now, we can deploy the Migrator contract in the template to ThunderCore testnet.
Unix-like system
Windows CMD
Windows Powershell
# Using NPM
KEY=0xPrivateKey npm exec -- truffle migrate --network thunder-testnet --reset
# or using Yarn
KEY=0xPrivateKey yarn truffle migrate --network thunder-testnet --reset
# Using NPM
set KEY=0xPrivateKey & npm exec -- truffle migrate --network thunder-testnet --reset
# or using Yarn
set KEY=0xPrivateKey & yarn truffle migrate --network thunder-testnet --reset
# Using NPM
$env:KEY='0xPrivateKey';npm exec -- truffle migrate --network thunder-testnet --reset
# or using Yarn
$env:KEY='0xPrivateKey';yarn truffle migrate --network thunder-testnet --reset
When it's done, should show messages like this:
Starting migrations...
