Exploring SuperTokens 002: Implementing SuperTokens Auth with Web Components and SolidJS

In this tutorial, we will be diving into hacking with SuperTokens 002 by integrating SuperTokens authentication with web components and SolidJS. SuperTokens is a secure and convenient authentication solution that helps developers easily add user authentication to their web applications. Web components allow developers to create reusable and encapsulated components for web applications. SolidJS is a reactive UI library that enables developers to build performant and maintainable web applications. By combining these technologies, you can create a secure and efficient authentication system for your web applications.

We will start by setting up a new SolidJS project and installing SuperTokens. Then, we will create web components for the login and register forms and integrate SuperTokens authentication with these components. Finally, we will test the authentication system by logging in and registering a new user.

Step 1: Setting up a new SolidJS project
To set up a new SolidJS project, you can use the following command in your terminal:

npx create-solid hello-supertokens
cd hello-supertokens
npm install

This command will create a new SolidJS project called hello-supertokens and install the necessary dependencies. Next, you can run the project using the command:

npm start

Step 2: Installing SuperTokens
To install SuperTokens in your SolidJS project, you can use the following command in your terminal:

npm install supertokens-auth-react
npm install supertokens-node

These commands will install the SuperTokens authentication library for the frontend and backend of your application. Next, you will need to set up SuperTokens on your backend server. You can follow the SuperTokens documentation for detailed instructions on setting up SuperTokens on your backend server.

Step 3: Creating web components for the login and register forms
To create web components for the login and register forms, you can use the following HTML code:

<template id="login-form">
  <form>
    <label for="email">Email:</label>
    <input type="email" id="email" name="email" required>
    <label for="password">Password:</label>
    <input type="password" id="password" name="password" required>
    <button type="submit">Login</button>
  </form>
</template>

<template id="register-form">
  <form>
    <label for="email">Email:</label>
    <input type="email" id="email" name="email" required>
    <label for="password">Password:</label>
    <input type="password" id="password" name="password" required>
    <button type="submit">Register</button>
  </form>
</template>

These templates define the structure of the login and register forms using HTML tags. You can customize the forms by adding additional input fields or styling.

Step 4: Integrating SuperTokens authentication with web components
To integrate SuperTokens authentication with the login and register forms, you can use the following SolidJS code:

import { createSignal } from 'solid-js';

const Login = () => {
  const [email, setEmail] = createSignal('');
  const [password, setPassword] = createSignal('');

  const handleLogin = async (event) => {
    event.preventDefault();

    // Call SuperTokens login API with email and password
  };

  return {
    email,
    setEmail,
    password,
    setPassword,
    handleLogin,
  };
};

const Register = () => {
  const [email, setEmail] = createSignal('');
  const [password, setPassword] = createSignal('');

  const handleRegister = async (event) => {
    event.preventDefault();

    // Call SuperTokens register API with email and password
  };

  return {
    email,
    setEmail,
    password,
    setPassword,
    handleRegister,
  };
};

This code defines two SolidJS components, Login and Register, that handle the login and registration logic. You can call the SuperTokens login and register APIs inside the handleLogin and handleRegister functions to authenticate users.

Step 5: Testing the authentication system
To test the authentication system, you can add the following code to your SolidJS project:

<Login />
<Register />

This code will render the login and register forms in your web application. You can test the authentication system by entering an email and password and clicking the login or register button.

In this tutorial, we have learned how to hack with SuperTokens 002 by integrating SuperTokens authentication with web components and SolidJS. By following these steps, you can create a secure and efficient authentication system for your web applications. Happy hacking!
