Bare Minimum Dapp: bm-dapp

A bare minimum dapp front-end for your decentralized web3 application. Create a one click dapp, bootstrapped with Create React App template.

• Simple, easy and fast
• Ready to use dapp with web3 login feature
• Includes only the bare minimum dependencies, so your app is not bloated
• Uses Web3modal under the hood, so you can add other providers easily with minimum efforts
• Reloads automatically on account and network changes

How to use

Bootstrap your dapp using Create React App by using the bm-dapp template

npx create-react-app my-app --template bm-dapp
yarn start

The app runs in development mode at http://localhost:3000. Clicking the Connect Web3 button will pop up Metamask by default(if web3 is enabled). For adding other providers, check Web3Modal Provider Options

Using with ethers

By default, ethers provider is used by bm-dapp. To use the connected provider, import Web3Context from the web3 directory present inside src directory.

import React, { useContext } from 'react';
import { Web3Context } from './web3';

const { account, provider } = useContext(Web3Context);

To initialize an ethers Contract object

const daiContract = new ethers.Contract(daiAddress, daiAbi, provider);

To connect a signer to the above Read-only contract

const signer = await provider.getSigner();
daiContract.connect(signer);

Or to initialize a Contract with signer

const daiWithSigner = new ethers.Contract(daiAddress, daiAbi, provider.getSigner());

For more details, please refer ethers documentation.

Using with web3

You can wrap the provider received from Web3Context with web3js and use it as below

import React, { useContext } from 'react';
import { Web3Context } from './web3';

const { account, provider } = useContext(Web3Context);
const web3 = new Web3(provider);

For more details, please refer web3js documentation
