Question 1

How do I handle JSON POST requests in Swift Express?

Accepted Answer

Parse JSON from the request body using .asJSON() method, as shown in the user registration example where it checks for a username field and returns a JSON response via JsonView.

Question 2

Swift Express vs Vapor: which is better for Swift web development?

Accepted Answer

Swift Express offers an Express.js-like syntax and unopinionated design, ideal for those familiar with Node.js. Vapor has a larger ecosystem and more built-in features, so choose Express for simplicity or Vapor for community support.

Question 3

How to serve static files like images or CSS in Swift Express?

Accepted Answer

Use StaticAction with routing patterns, such as app.get("/:file+", action: StaticAction(path: "public", param:"file")), to recursively serve files from a public directory, as documented in the examples.

Question 4

Does Swift Express support async/await or only futures?

Accepted Answer

It primarily relies on futures for asynchronous operations, based on Reactive Swift, as seen in the factorial handler. Native Swift async/await may require additional integration, given its current architecture.

Question 5

What template engines can I use with Swift Express?

Accepted Answer

It supports Stencil and Mustache out of the box; you can register them via app.views.register(StencilViewEngine()) for server-side templating, as shown in the hello.stencil example.

Question 6

Is Swift Express good for building microservices?

Accepted Answer

Yes, its asynchronous foundation and RESTful API support make it suitable for microservices, especially if you're already using Swift, but be mindful of the limited ecosystem compared to more established options.
