There are many great Web3 tools available on GitHub, however, I didn't find one that really suited my needs, so I created this simple React Hook. I want to connect to Metamask as quick as possible from any component, without rewriting all the network and account change logic. -- I think this is it.
Here's why:
- Your time should be focused on creating your project. A project that solves a problem and helps others
- You shouldn't be implementing the same logic over and over from scratch
- You shouldn't need enormous tool boxes when you only want a connection to the wallet.
Of course, no single hook will serve all projects since your needs may be different. So I'll be adding more in the near future. You may also suggest changes by forking this repo and creating a pull request or opening an issue. Thanks in advance to all the people who wants to put more into the project!
<!-- GETTING STARTED -->Getting Started
Install via npmjs
Easiest option is installing the package from npm with;
# via npm
npm i use-metamask
# or via yarn
yarn add use-metamask
But if you would like to build a package locally, follow this below;
Build from source
You'll need some prerequisites in order to be able build the package.
- npm > 12.13.0 (best installing via nvm)
npm install npm@latest -g
- yarn (optional)
https://classic.yarnpkg.com/en/docs/install
Installation
- Clone the repo
git clone https://github.com/mdtanrikulu/use-metamask.git
- Install NPM packages
# via npm npm install # via yarn yarn
- Build the Package
# via npm npm run build # via yarn yarn build
- Prepare Tar Package
npm pack # now the package is ready to use, you can simply do "npm i ./pathoftarfile/use-metamask-1.0.0.tgz" in your project
Usage
- 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(
<MetamaskStateProvider>
<App />
</MetamaskStateProvider>
document.getElementById('root')
);
- Import your hook to your App component
import { useEffect, useState } from "react";
import { useMetamask } from "use-metamask";
// you can use any web3 interface
// import { ethers } from "ethers";
// import Web3 from "web3";
function App() {
const { connect, metaState } = useMetamask();
//...
- Call
connect
async method with your favorite Web3Interface library
//...
function App() {
const { connect, metaState } = useMetamask();
// instead of calling it from useEffect, you can also call connect method from button click handler
useEffect(() => {
if (!metaState.isConnected) {
(async () => {
try {
await connect(Web3);
} catch (error) {
console.log(error);
}
})();
}
}, []);
- Now you can reach all information under
metaState
object; (they will be updated in case of any change in metamask)
// all connected Metamask accounts
// account: Array [ "0x68bbaeb98ac22e9e6516fb35c8d27ded05bc0607" ]
// current connected chain id and name
// chain: Object { id: "4", name: "rinkeby" }
// shows if Metamask Extension is whether exist or not in the user's browser
// isAvailable: true
// shows if connection is established with at least one metamask account
// isConnected: true
// web3 instance of Web3 interface you provided
// web3: Object { _isProvider: true, anyNetwork: true, _maxInternalBlockNumber: -1024, … }
Note: If you would like to check if Metamask is already connected to your dapp or not, you can call getAccounts
method beforehand.
You can also get chain information by calling getChain
method, without the need to call the connect
method.
const { connect, getAccounts, getChain, metaState } = useMetamask();
useEffect(() => {
if (metaState.isAvailable) {
(async () => {
try {
/* you can get the information directly
* by assigning them to a variable,
* or from metaState.account and metaState.chain
*/
let account = await getAccounts();
let chain = await getChain();
} catch (error) {
console.log(error);
}
})();
}
}, []);
