Question 1

How do I deploy a Frank app to Heroku?

Accepted Answer

Frank examples include deployment to Heroku; you need to set up a Procfile and configure the Swift build for release, as shown in the linked full example repository. Ensure your Package.swift includes Frank as a dependency.

Question 2

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

Accepted Answer

Frank is a lightweight DSL focused on type-safe routing, ideal for simple APIs or prototypes. Vapor is a full-featured framework with ORM, authentication, and real-time support, better for complex applications.

Question 3

How to handle JSON requests in Frank?

Accepted Answer

Frank doesn't have built-in JSON parsing; you must manually parse request bodies using Swift's Codable or libraries like SwiftyJSON, then return ResponseConvertible types such as Response with appropriate headers.

Question 4

Can I use Frank with databases like MySQL or PostgreSQL?

Accepted Answer

Yes, but Frank itself doesn't include database integration. You'll need to use Swift database drivers (e.g., SwiftMySQL or PostgresClientKit) and handle connections directly in your route handlers.

Question 5

How to add authentication to a Frank application?

Accepted Answer

Authentication isn't built into Frank; implement it by checking request headers or tokens in route handlers, or use middleware if your Nest-compatible server supports it, requiring custom Swift code.

Question 6

What templating engines work with Frank besides Stencil?

Accepted Answer

Frank can integrate with any templating engine via Swift, but Stencil is the primary example. You can adapt others like Mustache or custom solutions by creating similar helper functions for rendering.
