In this Part 12 of our React POS (Point of Sale) App Development Series, we will learn how to fetch single category data from the backend API and automatically load it inside the Edit Category form in React.
After creating the Edit Category component, the next important step is retrieving the existing category details using the category ID from the URL. In this tutorial, we will build a complete fetchCategory() function using Axios GET request, along with proper JWT authentication token handling. We will also use the useEffect hook to call the API automatically when the component loads or when the ID changes.
On the backend side, we will create a secure API route in Node.js and Express to fetch a single category record from the database. This includes using authenticateToken middleware for security and applying Express Validator to validate the category ID parameter. We will also handle common API errors like invalid ID, category not found, and database errors with proper status codes.
By the end of this video, your Edit Category page will correctly display the category name and status automatically, making your POS (Point of Sale) system more professional and dynamic.
📌 In the next video, we will update category data and submit the edit form to the backend API.
