Filtering Data

The video tutorial explains how to enhance an API by adding options for better data targeting using query strings. It focuses on the 'get tasks' route, which returns an array of tasks, and demonstrates how to filter tasks based on their completion status. The tutorial also covers setting up query strings in the URL structure, similar to a weather app example, and testing the implementation using Postman. The goal is to allow users to fetch only the necessary data, improving efficiency and user experience.

Why is the 'get tasks' route significant in handling large datasets?

• It is the only route available.

• It can return an array of multiple documents.

• It returns a single document.

• It does not require any query options.

What is the purpose of using query strings in URLs?

• To change the URL structure.

• To fetch all data without filtering.

• To filter data based on specific criteria.

• To increase the speed of data fetching.

How does the 'populate' method help in filtering tasks?

• It changes the URL structure.

• It allows specifying which tasks to match.

• It deletes unnecessary tasks.

• It automatically completes tasks.

What is the role of the 'match' option in task filtering?

• To specify which tasks to match based on criteria.

• To specify which tasks to delete.

• To change the task description.

• To create new tasks.

How can query string values be converted into Boolean values?

• By changing the URL structure.

• By using a loop.

• By comparing the string values to 'true' or 'false'.

• By using a simple assignment.

What happens if the query string 'completed' is not provided?

• Only completed tasks are returned.

• Only incomplete tasks are returned.

• No tasks are returned.

• All tasks are returned regardless of their completion status.

What is the first step in testing the task filtering logic with Postman?

• Change the URL structure.

• Create a new user.

• Delete all existing tasks.

• Create multiple tasks with varying completion statuses.

What should be the expected result when 'completed' is set to 'true' in the query string?

• No tasks are returned.

• Only completed tasks are returned.

• Only incomplete tasks are returned.

• All tasks are returned.

How can you verify that the task filtering logic works as expected?

• By checking the URL structure.

• By observing the tasks returned in Postman.

• By creating new tasks.

• By deleting all tasks.

What is the benefit of using query strings for task filtering?

• It changes the task descriptions.

• It increases the number of tasks.

• It allows for more targeted data retrieval.

• It simplifies the code.
