In this video (Part 17) of our React Point of Sale Application series, In this part, we will complete one of the most important features in any Point of Sale System using React and Node.js - inserting new user data into a MySQL database.
First, we will work on the frontend inside the Add User component of our React.js project. We will create a proper handleSubmit() function using async/await, prevent default form refresh, clear old error messages, and apply validation for required fields. We will also validate the email format using regex before sending data to the backend API.
After frontend validation, we will send the form data using Axios POST request along with the JWT token stored in localStorage. Once the API call is successful, the app will automatically redirect to the Users page using React Router DOM navigation.
Next, we will move to the backend using Node.js + Express.js and create a secure REST API route for inserting user records into MySQL. We will apply request validation using express-validator, restrict access using authentication middleware, check duplicate email entries, hash passwords using bcrypt, and insert user data safely using parameterized queries.
Finally, we will test everything in the browser and confirm that the new user appears inside the DataTable list.
This tutorial is perfect for anyone building a React POS system, learning Node.js React.js MySQL CRUD, or developing a real-world full stack POS application.
