Node.js API Masterclass with Express and MongoDB - Geospatial Query - Get Bootcamps Within Radius

The video tutorial explains how to create a route and controller method to find boot camps within a specified radius of a ZIP code using geospatial data. It covers setting up the method, calculating the Earth's radius, and querying the database. The tutorial also demonstrates setting up routes and testing them using Postman, emphasizing flexibility in implementation and user-friendliness by using ZIP codes instead of latitude and longitude.

What type of data allows us to perform operations to find boot camps within a radius?

• Numerical data

• Geospatial data

• Text data

• String data

Which operator is used to specify the center of a sphere in geospatial queries?

• CenterSphere

• GeoWithin

• GeoNear

• GeoIntersects

What is the purpose of using a geocoder in the method?

• To find the nearest boot camp

• To calculate the distance between two points

• To convert ZIP codes to latitude and longitude

• To store geospatial data

How is the radius of the Earth used in the calculation?

• It is added to the distance

• The distance is divided by it

• It is divided by the distance

• It is multiplied by the distance

What is the radius of the Earth in miles used in the calculation?

• 4000 miles

• 3963 miles

• 3950 miles

• 3960 miles

Which HTTP method is used to request boot camps within a radius?

• POST

• PUT

• GET

• DELETE

What tool is used to test the new route for boot camps?

• Insomnia

• Swagger

• Postman

• cURL

What is the expected result when querying a ZIP code with no boot camps?

• A redirect to another page

• An error message

• A success response with count 0

• A list of all boot camps

What is the next planned feature after implementing the boot camp radius search?

• User authentication

• Advanced querying with filters

• Real-time updates

• Data visualization

What additional functionality is planned for the boot camp search feature?

• Social media integration

• Course recommendations

• Pagination and field selection

• User reviews
