Connecting to remote backends
React Native allows you to use different solutions to connect to online resources such as APIs. First, you’ll learn about plain HTTP API connections. Later in this section, we’ll also have a look at more high-level solutions such as GraphQL clients and SDKs such as Firebase or Amplify. But let’s start with some general things.
Understanding the general principles of connections in React Native
No matter what connection solution you use in your React Native app, it is always a good idea to use JavaScript Object Notation (JSON) as the format for your data transfer. Since React Native apps are written in JavaScript and JavaScript plays very well with JSON, this is the only logical choice.
Next, regardless of which connection solution you use, always wrap your API calls in a service. Even if you are sure about the connection solution you chose, you may want or have to replace it in a few years.
