Vapor (web framework)

Vapor is an open source web framework written in Swift. It can be used to create RESTful APIs, web apps, and real-time applications using WebSockets. In addition to the core framework, Vapor provides an ORM, a templating language, and packages to facilitate user authentication and authorization.[4]

History

Vapor 0.1.0 was released as a proof of concept for Swift on the server a month after Apple open sourced Swift and began Linux platform support on December 3, 2015.[8] Vapor 1.0[9] arrived in September 2016, followed by the release of Vapor 2.0 in May 2017.[10]

The framework was rewritten for Vapor 3.0[11] to be built on Apple's non-blocking networking framework SwiftNIO. Vapor 3 was released in May 2018. Apple cited the speed with which Vapor (along with Kitura) adopted the new SwiftNIO framework on the main Swift.org server page.[12]

Vapor 3's beta period saw educational material published by Packt[13][14][15], Paul Hudson[16], Razeware LLC[17], and lynda.com[18]. Vapor was recognized by Swift.org with an official Swift Forum in its inaugural group of Related Projects[19] in May 2018.

Vapor 4[20]'s Alpha 1 Release started in May 2019.
