In Part 31 of our React POS App series, we build a complete Order Management data listing using jQuery DataTables with server-side processing. You'll learn how to load large order records efficiently inside a React point of sale dashboard and keep everything secure with JWT authentication.
On the frontend, we add a useEffect hook to initialize DataTables only once, pull the JWT token from localStorage, and configure DataTables to use processing + serverSide mode. Then we connect the table to a REST API using an AJAX setup (GET request + Authorization header). Finally, we map table columns for order number, order total (2 decimals), user name, created date, and an action column with View Details and Delete buttons.
On the backend (Node.js + Express + MySQL), we create a dedicated order routes file and build a DataTables-compatible endpoint. You'll see how to validate DataTables params using express-validator, protect routes using the JWT middleware, and write safe SQL queries with search, sorting, pagination, and total/filtered counts. The response is returned in the exact DataTables format (draw, recordsTotal, recordsFiltered, data) so the UI works smoothly.
If you’re building a POS system using React and Node.js, this episode helps you scale order lists for real-world retail apps.
