Use-Google-Auth

A single React Hook that loads the google api script in the head of your application and provides login and logout with Google functionality.

Installation

npm install @nightowl-developers/use-google-auth

yarn add @nightowl-developers/use-google-auth

Usage

Usage is pretty straight-forward. The hook returns two functions that can be attached to a button element.

import * as React from 'react'

import useGoogleAuth from '@nightowl-developers/use-google-auth'

const MyComponent = () => {
  const [isLoggedIn, setIsLoggedIn] = React.useState(false)
  
  const {
    signIn,
    signOut,
  } = useGoogleAuth({
    clientId: 'your-google-client-id',
    onLoginChange: (loggedIn) => {
      setIsLoggedIn(loggedIn)
    },
    onLoginSuccess: (response) => {
      setIsLoggedIn(true)
      console.log('logged in success', response)
    },
    onLoginFailure: (error) => {
      setIsLoggedIn(false)
      console.log('logged in failure', error)
    },
  })
  
  return <>
    {isLoggedIn && <button onClick={signIn}>Sign In</button>}
    
    {!isLoggedIn && <button onClick={signOut}>Sign Out</button>}
  </>
}

Credit to Original Author

This package is a moderately refactored version of React Google Login. Below are the changes that have been made to fit my own needs.

code simplified to a single React Hook
improved Hook prop names to better describe their use-case
appens the google api script to the element
added onLoginChange callback prop to listen to revoked permissions or expired tokens
added onLogoutSuccess callback prop to execute code when a user successfully logs out
