APIs are digital messengers that help different computer programs talk to each other. Think of them as translators who ensure your weather app can understand information from weather databases, or your food delivery app can communicate with restaurant systems. Web APIs specifically work over the internet, connecting the apps on your phone or computer with information stored on remote computers (servers).
The world of APIs has evolved over time. In the early days, a complex system called SOAP was commonly used, but developers found it too rigid and wordy. This led to the rise of REST APIs - a simpler approach that made it easier to connect systems. However, as mobile apps became popular, REST showed limitations because it often required multiple back-and-forth conversations to get all needed information, draining battery and data. To solve this problem, Facebook created GraphQL, allowing apps to ask for exactly what they needed in one conversation. Later, Google introduced gRPC, which focuses on speed but can be more complicated to set up.
Which one should you choose? REST is best for straightforward projects and widely understood by developers. GraphQL works great when you need flexible data requests, especially for mobile apps. gRPC is the speed champion, perfect for services that need to communicate quickly behind the scenes. Your choice ultimately depends on your specific needs - simplicity, flexibility, or raw speed. Have you worked with any of these technologies? Which one do you find most useful for everyday projects?
