description Vapor Overview

Vapor is an open-source web framework written in Swift, designed for building server-side applications and APIs. It leverages Swift's type safety and asynchronous programming model, utilizing SwiftNIO for high-performance networking. The framework provides tools for routing, ORM database integration via Fluent, and templating, making it suitable for macOS and Linux backend deployments.

help Vapor FAQ

Can Vapor run Swift applications on Linux?

Yes, Vapor is widely used to run server-side Swift on Linux as well as macOS. Production deployments commonly package the application in Docker or run the compiled Swift executable behind a reverse proxy.

Which database layer does Vapor use?

Vapor's primary object-relational and database toolkit is Fluent. Fluent provides models, migrations, and drivers for databases including PostgreSQL, MySQL, and SQLite.

Does Vapor use SwiftNIO under the hood?

Yes, Vapor is built on Apple's SwiftNIO networking framework. Modern Vapor code also supports Swift's async and await syntax, reducing the need to work directly with event-loop futures in routine handlers.

What is the Vapor equivalent of a server-side template engine?

Leaf is Vapor's templating language for generating HTML and other text responses. An API-only Vapor service can skip Leaf and return Codable JSON models instead.
