In this video (Part 13) of our React Point of Sale Application series, we will implement the Update Category feature using MySQL. This is an important part of the Category Management module where we allow users to edit and update category details from the frontend and store the updated data inside the database.

First, we will work on the React frontend Edit Category component and create a handleSubmit() function to send updated form data to the backend. We will also add proper validation, error handling, and prevent empty category names before sending the request. Using Axios PUT request, we will securely send category name and status along with the JWT token.
After that, we will move to the Node.js + Express backend, where we will create a PUT API endpoint for updating category data. We will use Express Validator to validate the category ID, category name, and category status. Then we will write MySQL queries to check duplicate category names, update the category record, and return proper responses like 409 Conflict, 404 Not Found, and 500 Server Error.
Finally, we will test the complete update feature in the browser and confirm the updated category appears correctly in the jQuery DataTables list. We will also verify soft delete functionality by changing status from Active to Inactive.
