Prerequisites

To complete the "Authsignal Authentication in React Next.js" tutorial, you will need to have the following prerequisites:

  • Basic knowledge of React and Next.js
  • Node.js and npm installed on your machine
  • A text editor or IDE, such as Visual Studio Code or Sublime Text
  • An Authsignal account and API key
  • A basic understanding of authentication concepts, such as OAuth 2.0 and OpenID Connect

It is recommended that you have some experience with React and Next.js before starting this tutorial, as we will be focusing on implementing Authsignal authentication in a Next.js application. You will also need to have Node.js and npm installed on your machine, as we will be using these tools to set up and run our application. Additionally, you will need an Authsignal account and API key to use the Authsignal authentication service. Finally, a basic understanding of authentication concepts, such as OAuth 2.0 and OpenID Connect, will be helpful in understanding the authentication flow we will be implementing.

React Next.js Authsignal step by step setup and configuration

Integrating Authsignal into a React Next.js project is a straightforward process. First, we need to install the Authsignal SDK using npm. We can do this by running the following command in our project directory:

npm install @authsignal/sdk

Once we have installed the Authsignal SDK, we need to initialize it with our API key. We can do this by creating a new file called authsignal.js in our project directory and adding the following code:

import { Authsignal } from '@authsignal/sdk';

const authsignal = new Authsignal({
  apiKey: 'YOUR_API_KEY',
});

export default authsignal;

In this code, we import the Authsignal class from the @authsignal/sdk package and create a new instance of it with our API key. We then export this instance so that we can use it throughout our application.

Next, we need to create a login page where users can authenticate themselves using Authsignal. We can do this by creating a new file called login.js in our pages directory and adding the following code:

import authsignal from '../authsignal';

export default function Login() {
  const handleLogin = async () => {
    const { token } = await authsignal.login();
    // Save the token to local storage or a cookie
  };

  return (
    <div>
      <h1>Login</h1>
      <button onClick={handleLogin}>Login with Authsignal</button>
    </div>
  );
}

In this code, we import the authsignal instance we created earlier and define a handleLogin function that calls the login method on the authsignal instance. This method will open the Authsignal login dialog, where the user can authenticate themselves. Once the user has successfully authenticated, the login method will return an access token, which we can save to local storage or a cookie.

Finally, we need to protect our application routes using Authsignal. We can do this by creating a higher-order component (HOC) that checks if the user is authenticated before rendering the protected route. We can create a new file called withAuth.js in our project directory and add the following code:

import authsignal from './authsignal';

export default function withAuth(Component) {
  return function WithAuth(props) {
    const isAuthenticated = authsignal.isAuthenticated();
    if (!isAuthenticated) {
      // Redirect the user to the login page
      return null;
    }
    return <Component {...props} />;
  };
}

In this code, we define a new HOC called withAuth that takes a component as an argument and returns a new component that checks if the user is authenticated using the isAuthenticated method on the authsignal instance. If the user is not authenticated, we can redirect them to the login page. If the user is authenticated, we render the protected route using the Component argument passed to the HOC. We can then use this HOC to protect our application routes by wrapping them with the withAuth function.

Authsignal configuration options in React Next.js

Here are the Authsignal configuration options for React Next.js integration:

  • apiKey - Your Authsignal API key.
  • authDomain - The Authsignal authentication domain to use.
  • redirectUri - The URI to redirect to after authentication.
  • logoutUri - The URI to redirect to after logout.
  • scopes - The scopes to request during authentication.
  • state - The state to include in the authentication request.
  • nonce - The nonce to include in the authentication request.
  • responseType - The response type to use during authentication.
  • responseMode - The response mode to use during authentication.
  • prompt - The prompt to use during authentication.
  • maxAge - The maximum age of the authentication session.
  • ui - The UI configuration for the Authsignal login dialog.

The apiKey option is required and specifies your Authsignal API key. The authDomain option specifies the Authsignal authentication domain to use. The redirectUri option specifies the URI to redirect to after authentication. The logoutUri option specifies the URI to redirect to after logout.

The scopes option specifies the scopes to request during authentication. The state option specifies the state to include in the authentication request. The nonce option specifies the nonce to include in the authentication request. The responseType option specifies the response type to use during authentication. The responseMode option specifies the response mode to use during authentication. The prompt option specifies the prompt to use during authentication.

The maxAge option specifies the maximum age of the authentication session. The ui option specifies the UI configuration for the Authsignal login dialog. These configuration options can be used to customize the authentication flow and the appearance of the Authsignal login dialog.
