Vue 3 Express JWT Authentication


A full-stack authentication system built with Vue 3, Express.js, JSON Web Tokens (JWT), and MySQL. This project provides user registration (sign-up) and authentication (sign-in) features, ensuring secure access to your application.


Before you begin, ensure you have met the following requirements:

  • MySQL: You need to have MySQL installed on your local machine. If you haven’t installed it yet, you can download and install MySQL from the official website.

    Ensure that you have the MySQL server up and running, and you can access it using a MySQL client.

  • Node.js: This project requires Node.js. If you don’t have Node.js installed, you can download it from the official website.

  • npm (Node Package Manager): npm comes bundled with Node.js. You can verify your npm installation by running npm -v in your terminal.
