Using Leaf

This section outlines how to import the Leaf package both with or without a Vapor project.

With Vapor

The easiest way to use Leaf with Vapor is to include the Leaf provider.

import PackageDescription

let package = Package(
    name: "Project",
    dependencies: [
        .Package(url: "https://github.com/vapor/vapor.git", majorVersion: 2),
        .Package(url: "https://github.com/vapor/leaf-provider.git", majorVersion: 1)
    ],
    exclude: [ ... ]
)

The Leaf provider package adds Leaf to your project and adds some additional, Vapor-specific conveniences like drop.stem().

Use import LeafProvider.

Just Leaf

At the core of the Leaf provider is a fast, pure Swift templating engine. You can use it with any of your Swift packages or server-side Swift applications.

import PackageDescription

let package = Package(
    name: "Project",
    dependencies: [
        ...
        .Package(url: "https://github.com/vapor/leaf.git", majorVersion: 2)
    ],
    exclude: [ ... ]
)

Use import Leaf to access the Leaf.Stem class.
