SOLID.JS & SUPABASE Authentication App

Hey guys, welcome to yet another article of a hands-on guide for creating a fullstack application, in today's dynamic world of web development, ensuring the security and dependability of authentication systems stands as an absolute necessity. As a developer, I recognize the paramount importance of building robust authentication mechanisms. With the advent of modern frontend frameworks like Solid.js and the emergence of feature-rich backend services like Supabase, I find myself equipped with powerful tools to integrate authentication into my applications.

I have to confess, this was the first time to try Supabase, and solid.js for that matter, but I was really surprised from the perfection both technologies brought together to authenticate the login mechanism.
Here's the video if you prefer to watch it:

But for now, let me give you a practical demonstration, showcasing how I integrate Solid.js and Supabase to construct a secure web application. I'm gonna show you how these advanced technologies synergize to establish a resilient infrastructure, safeguarding user data and facilitating access control.

Understanding the Project

The repository we'll be working with contains a Solid.js application that showcases how to integrate authentication using Supabase. Before diving into the implementation details, let's understand the prerequisites and the project structure.


Before getting started, ensure you have the following:

  • Node.js and npm: Ensure Node.js and npm (Node Package Manager) are installed on your system.
  • Supabase Account: Sign up for a Supabase account to leverage its authentication and database services.

Getting Started
1-Clone the Repository: Begin by cloning the repository to your local machine.

git clone
Enter fullscreen mode Exit fullscreen mode

2- Navigate to the Project Directory: Move into the project directory.

cd solidjs_supabase_auth
Enter fullscreen mode Exit fullscreen mode

3- Install Dependencies: Install project dependencies using npm.

npm install
Enter fullscreen mode Exit fullscreen mode

4- Set Up Supabase: Create a Supabase project and configure your credentials in a .env.local file.
5- Start the Development Server: Launch the Solid.js development server.

npm run dev
Enter fullscreen mode Exit fullscreen mode

Application Structure

The project structure is organized into components responsible for various authentication-related tasks:

Register Component: Handles user registration.
Login Component: Manages user authentication.
Dashboard Component: Renders the authenticated user's dashboard.
Additional Resources


At the end of the day, this is a great example to show combining the simplicity and reactivity of Solid.js with the powerful authentication capabilities of Supabase, developers can create secure and feature-rich web applications with ease. This project serves as a practical guide to integrating authentication into your Solid.js applications, empowering you to build robust and user-friendly experiences for your users.

Thank you for reading, until the next time :-)
