Multiwallet UI

This package provides a React wallet selection modal and state management for Multiwallet connectors.

Usage

yarn add @renproject/multiwallet-ui @material-ui/core @material-ui/icons
# For each chain / connector
yarn add @renproject/multiwallet-{DESIRED_CHAIN}-{DESIRED_WALLET}-connector
# Ensure peer dependencies are installed

At the root of your app, add the provider

import React from 'react';
import ReactDOM from 'react-dom';

import { MultiwalletProvider } from '@renproject/multiwallet-ui';
import App from './App';

ReactDOM.render(
  <MultiwalletProvider>
    <App />
  </MultiwalletProvider>,
  document.getElementById('root')
);

In your app, configure the desired providers for their chains eg.

import { EthereumInjectedConnector } from '@renproject/multiwallet-ethereum-injected-connector';
import { EthereumWalletConnectConnector } from '@renproject/multiwallet-ethereum-walletconnect-connector';
import { BinanceSmartChainInjectedConnector } from '@renproject/multiwallet-binancesmartchain-injected-connector';

const options = {
  chains: {
    ethereum: [
      {
        name: 'Metamask',
        logo: 'https://avatars1.githubusercontent.com/u/11744586?s=60&v=4',
        connector: new EthereumInjectedConnector({ debug: true }),
      },
      {
        name: 'WalletConnect',
        logo: 'https://avatars0.githubusercontent.com/u/37784886?s=60&v=4',
        connector: new EthereumWalletConnectConnector({
          rpc: {
            42: `https://kovan.infura.io/v3/${process.env.INFURA_KEY}`,
          },
          qrcode: true,
          debug: true,
        }),
      },
    ],
    bsc: [
      {
        name: 'BinanceSmartWallet',
        logo: 'https://avatars2.githubusercontent.com/u/45615063?s=60&v=4',
        connector: new BinanceSmartChainInjectedConnector({ debug: true }),
      },
    ],
  },
};

Finally, render the modal and use the useMultiwallet hook to request a connection to the chain.

import * as React from 'react';
import { WalletPickerModal, useMultiwallet } from '@renproject/multiwallet-ui';
// import options object

const WalletDemo: React.FC = () => {
  const { enabledChains } = useMultiwallet();
  return (
    <div>
      {Object.entries(enabledChains).map(([chain, connector]) => (
        <span key={chain}>
          {chain}: Status {connector.status} to {connector.account}
        </span>
      ))}
    </div>
  );
};

const App = () => {
  const [open, setOpen] = React.useState(false);
  const [chain, setChain] = React.useState('');
  const setClosed = React.useMemo(() => () => setOpen(false), [setOpen]);

  return (
    <>
      <WalletDemo />
      <button
        onClick={() => {
          setChain('ethereum');
          setOpen(true);
        }}
      >
        Request Ethereum
      </button>
      <button
        onClick={() => {
          setChain('bsc');
          setOpen(true);
        }}
      >
        Request BSC
      </button>
      <WalletPickerModal
        open={open}
        options={{
          chain,
          onClose: setClosed,
          config: options,
          targetNetwork: 'mainnet',
        }}
      />
    </>
  );
};

See the /example directory for a working example, or check the storybook as detailed below for further usage guides.

Developing

This library uses TSDX to bootstrap, build and run tests.

Commands

TSDX scaffolds your new library inside /src, and also sets up a Parcel-based playground for it inside /example.

The recommended workflow is to run TSDX in one terminal:

npm start # or yarn start

This builds to /dist and runs the project in watch mode so any edits you save inside src causes a rebuild to /dist.

Then run either Storybook or the example playground:

Storybook

Run inside another terminal:

yarn storybook

This loads the stories from ./stories.

NOTE: Stories should reference the components as if using the library, similar to the example playground. This means importing from the root project directory. This has been aliased in the tsconfig and the storybook webpack config as a helper.

Example

Then run the example inside another:

cd example
npm i # or yarn to install dependencies
npm start # or yarn start

The default example imports and live reloads whatever is in /dist, so if you are seeing an out of date component, make sure TSDX is running in watch mode like we recommend above. No symlinking required, we use Parcel's aliasing.

To do a one-off build, use npm run build or yarn build.

To run tests, use npm test or yarn test.

Configuration

Code quality is set up for you with prettier, husky, and lint-staged. Adjust the respective fields in package.json accordingly.

Jest

Jest tests are set up to run with npm test or yarn test.

Bundle analysis

Calculates the real cost of your library using size-limit with npm run size and visulize it with npm run analyze.

Setup Files

This is the folder structure we set up for you:

/example
  index.html
  index.tsx       # test your component here in a demo app
  package.json
  tsconfig.json
/src
  index.tsx       # EDIT THIS
/test
  blah.test.tsx   # EDIT THIS
/stories
  Thing.stories.tsx # EDIT THIS
/.storybook
  main.js
  preview.js
.gitignore
package.json
README.md         # EDIT THIS
tsconfig.json

Rollup

TSDX uses Rollup as a bundler and generates multiple rollup configs for various module formats and build settings. See Optimizations for details.

TypeScript

tsconfig.json is set up to interpret dom and esnext types, as well as react for jsx. Adjust according to your needs.

Continuous Integration

GitHub Actions

Two actions are added by default:

• main which installs deps w/ cache, lints, tests, and builds on all pushes against a Node and OS matrix
• size which comments cost comparison of your library on every pull request using size-limit

Module Formats

CJS, ESModules, and UMD module formats are supported.

The appropriate paths are configured in package.json and dist/index.js accordingly. Please report if any issues are found.

Named Exports

Per Palmer Group guidelines, always use named exports. Code split inside your React app instead of your React library.
