Vapor is a popular open-source web framework that allows developers to create web apps and APIs in Swift. In this course, Ron Buencamino dives into using Swift on the server with Vapor. Ron covers how server-side Swift came about, and its importance, what the Vapor framework does, and how it compares to similar frameworks. He shows how to set up a local development environment, install open-source Swift and the Vapor framework, set up a web server, and even how to deploy to an external cloud service—Heroku—to host your final project.
