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.
