Introduction
Integrating user authentication is a crucial part of web application development. By using SolidJS together with Supabase, you can implement an effective and secure user authentication system. In this tutorial, we'll walk you through the steps needed to integrate user authentication into a SolidJS app using Supabase.
Initial configuration
Creating a Supabase Project:
Go to Supabase and create a new project.
After creation, go to your project dashboard and navigate to settings to find your project URL and API keys.
SolidJS App Setup:
Create a new SolidJS app using the following command
npx create-solid@latest my-solid-appcd my-solid-appSupabase integration
Installing the Supabase Client:
Install the Supabase client into your SolidJS project with the following command:
npm install @supabase/supabase-jsSupabase Client Configuration:
Create a file called supabaseClient.js in your project's src folder.
In this file, initialize the Supabase client with the project URL and API key:
import { createClient } from '@supabase/supabase-js';
const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseAnonKey = 'YOUR_SUPABASE_ANON_KEY';
const supabase = createClient(supabaseUrl, supabaseAnonKey);
export default supabase;
Authentication Implementation
Creating a Login Page:
Create a new file called Login.jsx in the src/components folder.
Use the following code snippet as a starting point for your login page:
import { createSignal } from 'solid-js';
import { supabase } from '../supabaseClient';
const Login = () => {
const [email, setEmail] = createSignal('');
const [password, setPassword] = createSignal('');
const [loading, setLoading] = createSignal(false);
const handleLogin = async () => {
setLoading(true);
const { user, error } = await supabase.auth.signIn({ email: email(), password: password() });
setLoading(false);
if (error) {
console.error(error.message);
} else {
//Redirect to dashboard
}
};
return (
<div>
<input type="email" value={email()} onInput={(e) => setEmail(e.currentTarget.value)} placeholder="Email" />
<input type="password" value={password()} onInput={(e) => setPassword(e.currentTarget.value)} placeholder="Password" />
<button onClick={handleLogin} disabled={loading()}>Login</button>
</div>
);
};
export default Login;
User Session Management:
Manage the user session using SolidJS hooks and the Supabase client.
Conclusion
You now have a basic understanding of how to integrate user authentication into a SolidJS app using Supabase. This will allow you to create secure and functional SolidJS applications with a robust user authentication system.
