\0. Environment Setup

Create your DAPP using Starter Kits Template

Quick Start

npx create-react-app {YOUR_PROJECT_NAME} --template polygon-starter-kit
cd {YOUR_PROJECT_NAME}
npm run start

(npx comes from npm 5.2+ or later)

Then fireup your browser and go to http://localhost:3000/ to check your application.

When you are preparing to deploy your project to production settings, use npm run build to create a compressed bundle and deploy.

Immediate Configuration

There is no need for you to install or configurate tools like Webpack or Babel. They comes pre-configurated and hiddened, therefore you are provided with the full environment pack where you only need to worry about coding part.

Just create a project with the template, then you are good to go!

Create Application

You will need to use Node that is higher or equal to version 6 on your local computer(on server you don't have to). There is nvm(macOS/Linux) or nvm-windows to help you eaily switch between different Node versions.

Create a new application

npx create-react-app {YOUR_PROJECT_NAME} --template polygon-starter-kit

Then a new folder named {YOUR_PROJECT_NAME} will be created under current folder location. The File structures under this new folder is as below:

Truffle Environment Configuration

truffle-config.js

const mnemonic = process.env.MNEMONIC;
const HDWalletProvider = require("@truffle/hdwallet-provider");


module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 8545,     
      network_id: "*" // Match any network id
    },
    polygon: {
      provider: new HDWalletProvider(mnemonic, process.env.POLYGON_RPC),
      network_id: 137,
      confirmations: 2,
      timeoutBlocks: 200,
      skipDryRun: true
    },
    mumbai: {
      provider: new HDWalletProvider(mnemonic, process.env.POLYGON_MUMBAI_RPC),
      network_id: 80001,
      confirmations: 2,
      timeoutBlocks: 200,
      skipDryRun: true
    }

Create .env File under root folder

vim .env
MNEMONIC=" {YOUR_MNEMONIC OR YOUR_PRIVATE_KEY} "
POLYGON_RPC = " {PUBLIC_POLYGON_RPC} OR https://rpc-mainnet.matic.network"
POLYGON_MUMBAI_RPC = " {PUBLIC_POLYGON_MUMBAI_RPC} or https://rpc-mumbai.maticvigil.com/"
