Build me a simple task manager web app where I can add, edit, and delete tasks, then keep track of them as To do, In progress, or Done. Each task should let me set a priority, Low, Medium, or High, and optionally add a due date. I want a clean interface where I can search by task title and filter tasks by status or priority so it’s easy to find what I need.

Please make overdue tasks stand out when they are not marked done, and make sure the app feels responsive and easy to use. The backend should validate bad task data and return clear JSON errors, and if a status update fails, the UI should switch it back so it stays accurate. Use a modern React frontend with a Node and Express API connected to MongoDB, and include basic API tests for the main task actions. If you need to check anything current, look up the latest docs online first.
