Apodini Leaf is a small [Apodini](https://github.com/Apodini/Apodini) extension to support the [Leaf](https://github.com/vapor/leaf-kit) teamplating engine.
The [Leaf documentation](https://docs.vapor.codes/4.0/leaf/overview/) provides a good overview of the usage of Leaf.
## Integrate Swift Package
To use Apodini Leaf you have to add it as a depenency to your Swift Package in your Package.swift file. As Apodini Leaf is extending [Apodini](https://github.com/Apodini/Apodini) it is also currenlty using 0.X releases and every minor version number increment could include breaking changes. Therefore using `.upToNextMinor(from: "0.1.0")` is advised:
```swift
dependencies: [
.package(url: "https://github.com/Apodini/ApodiniLeaf.git", .upToNextMinor(from: "0.1.0")),
// More package dependencies ...
]
```
Next add ApodiniLeaf as a target dependency to your web service target:
```swift
.target(
name: "MyWebService",
dependencies: [
.product(name: "Apodini", package: "Apodini"),
.product(name: "ApodiniLeaf", package: "ApodiniLeaf"),
// More target dependencies ...
]
)
```
Now you can import ApodiniLeaf in your web service:
```swift
import ApodiniLeaf
```
## Usage
To use ApodiniLeaf, you have to define a `LeafConfiguration` in your `WebService` instance. You can pass in a `Bundle` or absolute path.
In this example we have defined [Swift Package resources using the resources definition](https://developer.apple.com/documentation/swift_packages/bundling_resources_with_a_swift_package) in our Package.Swift file:
```swift
.testTarget(
name: "MyWebService",
dependencies: [
// ...
],
resources: [
.process("Resources")
]
)
```
The folder structure looks like follows:
```
MyWebService
├── Package.swift
├── Resources
│ ├── Example.leaf
└── Sources
└── ...
```
The example Leaf file has the following content:
```html
#(title)
#(body)
```
We use the `Bundle.module` to access the created resources bundle in the `WebService` configuration to configure the `LeafRenderer` as follows:
```swift
struct TestWebService: WebService {
var configuration: Configuration {
LeafConfiguration(Bundle.module)
}
var content: some Component {
Text("Test")
}
}
```
Now that we have defined the configuration, we can use the `LeafRenderer` in our Apodini `Handlers` using the `@Environment` property wrapper:
```swift
struct ExampleHandler: Handler {
@Environment(\.leafRenderer) var leafRenderer: LeafRenderer
func handle() -> some ResponseTransformable {
struct ExampleContent: Encodable {
let title: String
let body: String
}
let content = ExampleContent(title: "Paul", body: "Hello!")
return leafRenderer.render(path: "Example", context: content)
}
}
```
The `ExampleHandler` uses the `@Environment` property wrapper to retrieve the `LeafRenderer` and uses a Swift `struct` to fill in the content and renders the HTML using the `LeafRenderer`'s `render(path:context:)` method. For more information about Leaf, please refer to the [Leaf documentation](https://docs.vapor.codes/4.0/leaf/overview/).
