React AuthJS Library

A simple and flexible authentication library for React applications, built on top of NextAuth.js.

Installation

To install the React AuthJS Library, run the following command in your project directory:

npm install react-authjs-library

Usage

1. Wrap your application with AuthProvider

First, wrap your main application component with the AuthProvider:

import { AuthProvider } from 'react-authjs-library';

function App() {
  return (
    <AuthProvider>
      {/* Your app components */}
    </AuthProvider>
  );
}

2. Use authentication components

The library provides several components and hooks for managing authentication:

SignInButton

import { SignInButton } from 'react-authjs-library';

function LoginPage() {
  return (
    <div>
      <h1>Login</h1>
      <SignInButton />
    </div>
  );
}

SignOutButton

import { SignOutButton } from 'react-authjs-library';

function Dashboard() {
  return (
    <div>
      <h1>Dashboard</h1>
      <SignOutButton />
    </div>
  );
}

ProtectedRoute

Wrap components that require authentication with ProtectedRoute:

import { ProtectedRoute } from 'react-authjs-library';

function PrivateContent() {
  return (
    <ProtectedRoute>
      <h2>This content is only visible to authenticated users</h2>
    </ProtectedRoute>
  );
}

3. Access authentication state

Use the useAuth hook to access the current authentication state:

import { useAuth } from 'react-authjs-library';

function UserProfile() {
  const { user, isAuthenticated, isLoading } = useAuth();

  if (isLoading) return <div>Loading...</div>;
  if (!isAuthenticated) return <div>Please sign in</div>;

  return (
    <div>
      <h1>Welcome, {user.name}!</h1>
      {/* Display user profile information */}
    </div>
  );
}

Configuration

To configure the authentication providers and options, you need to set up NextAuth.js in your project. Refer to the NextAuth.js documentation for detailed instructions on how to configure various authentication providers.

Important Notes

1. This library is a wrapper around NextAuth.js, so you'll need to configure NextAuth.js separately in your project.
2. Ensure you have the necessary backend setup to handle authentication requests.
3. The current implementation is designed for client-side usage. For server-side rendering or more advanced configurations, refer to the NextAuth.js documentation.

Customization

You can customize the appearance of the SignInButton and SignOutButton components by passing a className prop:

<SignInButton className="my-custom-button-class" />
<SignOutButton className="my-custom-button-class" />
