Node.js API Masterclass with Express and MongoDB - GeoJSON Location & Geocoder Hook - MapQuest API

The video tutorial explains how to use the node geocoder package to geocode addresses submitted by clients. It covers setting up MapQuest as the geocoding provider, configuring environment variables, and creating a utility file for geocoding. The tutorial also demonstrates implementing middleware to automatically geocode addresses and store them as geojson objects in a database. The video concludes with a preview of upcoming topics, including advanced querying and user authentication.

What is the primary purpose of geocoding in the context of this tutorial?

• To convert geographic coordinates into a readable address

• To visualize data on a map

• To convert an address into geographic coordinates

• To calculate the distance between two points

Which provider is used in this tutorial for geocoding?

• Google

How many free transactions does MapQuest offer per month?

• 10,000

• 15,000

• 20,000

• 25,000

What command is used to install the Node Geocoder package?

• npm install geocoder

Where should the API key be stored according to the tutorial?

• In the main application file

• In the database

• In a separate text file

• In the config environment file

What is the purpose of creating a utility file for geocoding?

• To store all API keys

• Callback function

Why is the address set to undefined before saving to the database?

• To comply with data privacy laws

• To save storage space

• To prevent duplicate data

• To ensure only the formatted address is stored

What additional functionality is planned for the next section of the tutorial?
