If you're into app development with Swift, then you might have heard of Vapor - a popular web framework that lets you build powerful, scalable backend systems in Swift.
Firstly, you need to set up your Vapor development environment. You can do this by installing Vapor using Homebrew:
brew install vapor/tap/vapor
Once installed, make sure you have a version of Xcode installed that supports Swift 5.1 or later, and then run the following command to create a new Vapor project:
vapor new MyProject
This will create a new Vapor project with all the necessary files and directories that you need to start building your backend system.
With your Vapor project set up, you can start building your first endpoint. An endpoint is simply a URL that your clients can use to interact with your backend system.
Open up the file called routes.swift in your project folder, and add the following code to create a new endpoint:
app.get("hello") { req in
return "Hello, Vapor!"
}
What this code does is create a new endpoint at /hello, and when your client visits that URL, it will return the string "Hello, Vapor!".
With your endpoint created, you can now test it out. Run the following command in your terminal:
vapor run serve
This will start up your Vapor server, and you should see output in your terminal indicating that your server is running.
Now visit http://localhost:8080/hello in your web browser, and you should see the message "Hello, Vapor!" displayed on the page.
Vapor development is a powerful tool for building scalable, high-performance backend systems in Swift. With a few simple commands, you can set up your development environment, create endpoints, and start building your app's backend. So give Vapor a try, and see what you can build!
