SSWG-0031: Vapor

The review of SSWG-0031: Vapor begins now and runs for two weeks, until April 6th, 2024.

Reviews are an important part of the Swift Server Work Group incubation process . All review feedback should be either on this forum thread or, if you would like to keep your feedback private, directly to the review manager (via email) or direct message in the Swift forums.

The package is being proposed at the Graduated maturity level. Please note the Maturity Justification inside the proposal for details and indicate which you find more appropriate as part of your review.

What goes into a review of a proposal?

The goal of the review process is to improve the proposal under review through constructive criticism and, eventually, become listed on the Swift Server Ecosystem index page .

When reviewing a proposal, here are some questions to consider:

  • What is your evaluation of the proposal and its APIs/implementation?
  • Is the problem being addressed relevant for the wider Swift on Server ecosystem?
  • Does this proposal fit well with the feel and direction of the Swift Server ecosystem?
  • If you have used other libraries in Swift or other languages, how do you feel that this proposal compares to those?
  • How much effort did you put into your review? A glance, a quick reading, or an in-depth study?

What can you say about a framework that is already so well known and used?

  • Vapor's API fits Swift's idea that you can start simple and learn the more advanced stuff when you need to;
  • Vapor was very quick in providing support for Swift concurrency;
  • "Graduated" seems fitting, considering the API stability, history of support, adoption, and constant bug/security fixes.

Personally, I've used Vapor in several hobby projects. Both APIs as well as full stack. With various persistence backing stores. And it has always been a pleasure to use.

Vapor is my default recommendation for a Swift on server framework. I.e. you are on the fence on what to use? Vapor is always a sound bet. If you have needs that are not aligned very well with Vapor, most likely you know about them already.

There's probably a lot more to say, see this as a start.
