In this video (Part 20) of our React Point of Sale Software series, we will implement the Update User Data feature using React.js, Node.js, Express.js, and MySQL. This is an important part of any Point of Sale system because user management is a core module in real-world POS software.
First, we work on the React frontend by updating the Edit User component. We create a handleSubmit() function to capture form submission, validate required fields like name, email, and status, and also validate the email format using regex. After validation, we send the updated user data to the backend using Axios PUT request with JWT token authentication.
Next, we move to the Node.js backend and create a secure Express PUT API to update user data in the MySQL database. We use express-validator to validate URL parameters and request body fields. Then we check for duplicate email conflicts before updating the user record. If everything is correct, we update the user data using a parameterized SQL query to prevent SQL injection.
Finally, we test the update feature in the browser and confirm that the updated user appears inside the jQuery DataTables list. We also demonstrate how to perform a soft delete by changing the user status from Active to Inactive.
📌 User Management Module is now completed! Next, we will begin the Product Management Module.
