@hello3/react

React package that contains functionality that is needed to easily setup authentication with Hello3. Simply wrap your app with the Hello3Provider and use the useHello3 hook to get started.

Example with Create React App

// index.tsx
import React from 'react'
import ReactDOM from 'react-dom'
import { Hello3Provider } from '@hello3/react'

import App from './App'

ReactDOM.createRoot(document.getElementById('root')).render(
  <Hello3Provider>
    <App />
  </Hello3Provider>
)

// App.tsx
import { useHello3 } from '@hello3/react'

function App() {
  const { user, showSignInModal, clearSession } = useHello3()

  return (
    <div>
      {user ? (
        <div>
          <p>Welcome, {user.address}!</p>
          <button onClick={clearSession}>Sign out</button>
        </div>
      ) : (
        <div>
          <p>Please sign in</p>
          <button onClick={showSignInModal}>Sign in with Hello3</button>
        </div>
      )}
    </div>
  )
}

Development

To install the local dependency in a test react project:

$ cd hello3-react
$ npm i && npm run build:dev
$ cd ../hello3-rest-react-app
$ npm i ../hello3-react

From there on the lib is linked, and when you change something in hello3-react, run again npm run build:dev to hot reload the package, or simply npm run build:esm for faster buildtime.

More documentation on integrating Hello3 is available on the docs website.
