In this article, we will see what does Object-Oriented Programming — abbr. OOP- means. Many times, we see it in action but do we really know what it actually implies for? Let’s jump right in.

Everything we see around is basically an object and OOP is a model that assumes everything is, well, an “object”.

This project is FreeCodeCamp‘s third APIs and Microservices Project. In this project, we’ll be create a simple URL shortener API.

We’ll be using Node.js/Express and MongoDB

Outline

• Create a MongoDB database on MongoDB Atlas.
• Install all the required npm packages.
• Define the environment variables.
• Create an express server.
• Connect to the database.
• Create the URL Model.
• Create the API routes post and get methods.
• Conclusion

Step 1: Create a MongoDB database on MongoDB Atlas

We learned before create a MongoDB database on MongoDB Atlas. You can check out the Freecodecamp MongoDB lecture and MongoDB documentation for more information.

We need…

I built this microservice for freeCodeCamp’s second APIs and Microservices Project.

Basically it accepts API requests and will respond with a JSON object containing the user’s IP address, preferred language and information about their browser and operating system.

I used freeCodeCamp’s Glitch boilerplate project. Here is a starter link.
