To implement Connect TronLink wallet using TronWeb in a React application, you can follow these steps:

Install TronWeb

Start by installing the TronWeb library in your React project. Open a terminal and navigate to your project directory, then run the following command:

npm install tronweb

Import TronWeb

In the component where you want to implement the TronLink wallet connection, import the TronWeb library at the top of the file:

import TronWeb from 'tronweb';

Set up TronWeb instance

Create a new instance of TronWeb in the component's constructor or using the useEffect hook if you're working with functional components:

const tronWeb = new TronWeb({
  fullHost: 'https://api.trongrid.io',
});

Connect TronLink wallet

Implement a function that connects the user's TronLink wallet to your application:

const connectTronLink = async () => {
  try {
    await tronWeb.setTronWeb(window.tronWeb);
    // TronLink is connected successfully
    console.log('Connected to TronLink!');
  } catch (error) {
    // TronLink connection failed
    console.error('Failed to connect to TronLink:', error);
  }
};

Trigger connection

Call the connectTronLink function when a user clicks a button or performs any other action to initiate the connection:

<button onClick={connectTronLink}>Connect TronLink Wallet</button>

Access TronLink data

Once connected, you can access various properties and methods provided by TronWeb. For example, to get the current address and balance, you can use the following code:

const currentAddress = tronWeb.defaultAddress.base58;
const balance = await tronWeb.trx.getBalance(currentAddress);
console.log('Address:', currentAddress);
console.log('Balance:', balance);

Remember, for this implementation to work, your users must have TronLink installed and running in their browsers. Make sure to handle cases where TronLink is not detected or the connection fails gracefully.
