Explaining what RESTful API is like you’re 5 years old

Introduction

Imagine you’re in a large library, filled with every book you could ever want to read. But this library is special—it’s not just for you; it’s for everyone’s computers and smartphones too. In this magical library, there’s a way to ask for a specific book and get it instantly, no matter where it is. This method is similar to what adults call a “REST API.” Let’s embark on a journey to understand how REST API helps computers and apps share information just like asking and getting books in our imaginary library.

What Is a REST API?

REST API is like a special language that computers use to talk to each other. When you use a smartphone app to check the weather, the app asks a computer somewhere else in the world for the weather information using this special language. The computer understands this request and sends back the weather details, so the app can show you if you need an umbrella or sunglasses.

The History Behind REST API

Long ago, before REST API, computers found it hard to talk to each other. They were like people from different parts of the world who couldn’t understand each other’s languages. A smart person named Roy Fielding in 2000 thought there should be an easier way for computers to share information. He created the rules for REST, making it simpler for computers to understand each other.

The Problem REST API Solves

Imagine if every time you asked for a book in the library, you had to fill out a complicated form, wait for days, and then get a bunch of books you didn’t want. That was what it was like for computers before REST API. They had to deal with complicated rules and often got more information than they needed. REST API made asking for and receiving information as easy as asking a librarian for a book and getting exactly what you asked for.

How REST API Works

Using REST API is like using a magic word to get what you want. When an app wants to show you a video, send a message, or find a friend online, it uses REST API to ask another computer for that information. The computer knows exactly how to find and send back what the app asks for, using simple, universal rules.

Summary

Just like a magical library where you can find and borrow any book instantly, REST API lets computers and apps quickly find and share information. It’s made the internet much easier to use, letting apps talk to each other in a simple, common language.

Conclusion

So, next time you’re using an app to watch videos, remember that there’s a special language working behind the scenes. REST API is the hero that helps your favorite apps talk to each other, making sure you have the information and entertainment you want at your fingertips. Just like magic, it connects the world’s information in ways that are easy for computers to understand and use.
