If you’re still unsure how everything works, think of the backend as follows: Our MongoDB is hosted on MongoLab and the node server is up on Heroku. Run the app and see what it returns. Written for beginners without any programming experience. Run the following command in the terminal (feel free to modify the url with your own heroku url). 2021 • All rights reserved.

Now that we have a solid understanding of the HTTP protocol, we should be ready to jump into the meat of this tutorial and get rolling. Whether you implement networking from scratch, or use Alamofire and Moya, you often end up with a complex and tangled code. Add a new class called AddViewController to the storyboard and wire it up with a segue. From Javascript’s Node to express and MongoDB to cURL and terminal to cocoapods and finally Alamofire, we dove into the details of what makes a REST API and how networking works. In the third line we use the app, which represents the express environment. Cocoapods is the de facto dependency manager for iOS projects. Multithreading is much the same way. Fortunately, Alamofire exists. We an define routes we want our database to accept as we’ll do in a moment.

Before we touch MongoLab or Heroku, let’s make sure you’re all set with Node.js. To make asynchronous network calls, you need to use many features of Swift and UIKit, like the URLSession class and the Codable. I’ve scoured the web and there isn’t a detailed tutorial that walks you through the steps from creating an API to interacting with it in an iOS app. Here is the JSON response of the server when we fetch the list of articles: And here is the response when we fetch a specific article: Also note that in our Article model we are using a custom object Category so it’s not enough to just declare Article as Codable because we need to make sure that all properties of Article conforms to Codable, in this case the standard library types already conforms to Codable but our custom type Category should conform to Codable as well. Remember the password. Even though there’s reason enough to go with a simple URLSession implementation, many of us still decide to implement their network layer by making use of Alamofire. Vim is a command line editor, much like Sublime Text or TextMate although it is built into the command line. As the command line suggests, you must close your current xcode project, open up the finder window, and now select the .xcworkspace cocoapods generated. In fact, each and every time you go to google.com or view your Facebook/Twitter feed, you are performing a GET request (and likely not even knowing it)! As soon as we’re done, we can migrate over to Alamofire. We will first experiment with cURL and then migrate our cURL requests to AlamoFire. Any type whose properties are codable automatically conforms to Codable just by declaring that conformance. Click this link to fire up MongoLab’s website and make an account. In a recent project I had to make a gzipped request to a service. However, I encourage you to research express and mongoose. When I was beginning my dive into Node, I was unsure how everything worked and many of the blogs I visited never explained what was ongoing.

MongoDB gives us a place to store all this data. Let’s start by defining our data models and conform to Codable protocol. But let’s refactor our APIClient and avoid the repetitive code : We have just created a new method called performRequest that will perform the request when passing the APIRouter and the completion parameters.
