Diving into the world of blockchain and decentralized applications can feel overwhelming at times, especially when trying to connect to wallets like Metamask. Luckily, the useMetamask React Hook is here to simplify the process! In this blog, we’ll walk through how to use this hook effectively in your React projects.

About the Project

The useMetamask React Hook is designed to help developers quickly connect their applications to Metamask without duplicating logic across components. Imagine it as a handy Swiss Army knife for your Web3 projects—always ready to help you tackle the task of connecting to the blockchain seamlessly!

Getting Started

Before diving into the code, let’s get your environment ready to use the useMetamask hook.

Prerequisites

• Node.js version 12.13.0 or higher (recommended to install via nvm)
• npm (package manager) installed
• yarn (optional but recommended)

Installation

There are two main ways to get started:

• Install via npm:

  npm i use-metamask

• Or via yarn:

  yarn add use-metamask

• To build from the source, follow these steps:
  1. Clone the repository:

     git clone https://github.com/mdtanrikulu/use-metamask.git

  2. Install NPM packages:

     npm install

  3. Build the package:

     npm run build

  4. Prepare the tar package:

     npm pack

Usage

Using the useMetamask hook is straightforward! Here’s how you can utilize it:

1. Wrap your App component with MetamaskStateProvider:

   import React from 'react';
   import ReactDOM from 'react-dom';
   import MetamaskStateProvider from 'use-metamask';
   import App from './App';
   
   ReactDOM.render(
     
       
     ,
     document.getElementById('root')
   );

2. Import the hook in your App component:

   import { useEffect, useState } from 'react';
   import useMetamask from 'use-metamask';

3. Connect using your favorite Web3 library:

   function App() {
     const [connect, metaState] = useMetamask();
   
     useEffect(() => {
       const connectWallet = async () => {
         if (!metaState.isConnected) {
           try {
             await connect(Web3);
           } catch (error) {
             console.log(error);
           }
         }
       };
   
       connectWallet();
     }, []);

4. Access the connection state and account details:

   console.log(metaState); // Access details like accounts, connected chain id, etc.

Roadmap

You can participate in shaping the future of this hook by checking out the open issues for proposed features and known bugs.

Troubleshooting

Here are some common issues and their fixes:

• Metamask is not connecting: Ensure Metamask is installed and configured in your browser.
• Incorrect version of Node: Ensure you have Node.js version 12.13.0 or later. You can check your version using node -v.
• Network issues: Make sure your network settings in Metamask are correct and match your application.
