To-Do List Application

This is a simple To-Do List application with the following features:

Task Management

1. Create Tasks: Users can create tasks with a title and description.

2. View Tasks: Users can view a list of all tasks.

3. Mark as Completed: Users can mark tasks as completed.

4. Edit Task Details: Users can edit task details.

5. Delete Tasks: Users can delete tasks.

Persistence

Tasks are stored and retrieved from a simple database. Currently, we use MySQL/MongoDB for data persistence.

Validation

1. Task Title Validation: Validation is implemented to ensure that task titles are not empty and the password is abc.

2. Mark as Completed Validation: Users can't mark a task as complete if it's already marked as such.

3. Error Handling: Errors are handled gracefully, and meaningful error messages are provided.

Frontend Setup

I also have completed a frontend in React:

   POST /todos

2. Viewing Tasks: Retrieve a list of all tasks using the following endpoint.
   GET /todos

   The response will be in a JSON format, providing a clear list of all tasks.

4. Deleting Tasks: Remove a task by using the delete endpoint.
   DELETE /todos/:id

5. Authentication: Login to start editing password is abc.

Code Structure

The code is organized as follows:

• app.js: Entry point of the application.
• routes/tasks.js: Handles the CRUD operations for tasks.
• models/taskModel.js: Defines the task schema and interacts with the database.
• config.js: Contains the database configuration.

Bonus (Optional)

Categorizing Tasks

Tasks can be categorized by introducing a "category" field in the task schema.

Feel free to explore and extend the application based on your needs!

Note: This is a basic To-Do List application, and further improvements and optimizations can be made based on specific requirements.
