In Part 36 of this React POS App series, we will learn how to submit order cart data from the frontend to the backend and store it in the database using a full stack React, Node.js, Express, and MySQL setup.
This tutorial shows how to create the submit order feature inside a React POS system. On the frontend, we build the createOrder function, decode the JWT token, prepare the order payload, calculate the cart total with tax, map cart items into order line data, and send everything to the backend using Axios POST API. We also handle success alerts, reset the order form, and display validation or server errors properly.
On the backend, we create a secure Express.js API route for order submission. We use JWT authentication middleware to protect the route and Express Validator to validate order number, total amount, user ID, and item details like product name, quantity, and price. After validation, we insert order data into the orders table and cart item data into the order_items table in MySQL.
Finally, we test the complete order flow in the browser by adding products to the cart, updating quantity, removing items, clicking the Pay button, and confirming that the order is saved successfully.
This video is part of a complete React POS App tutorial for beginners and full stack developers who want to build a real world point of sale system with React JS, Node JS, Express JS, MySQL, REST API, JWT authentication, and Axios.
