# Declarativity + Vapor
You could make your Vapor app look a little bit different ✈️
## How to install
via Swift Package Manager
```swift
.package(url: "https://github.com/MihaelIsaev/Vaporizer.git", from:"1.0.0"),
.target(name: "App", dependencies: [
.product(name: "Vaporizer", package: "Vaporizer")
]),
```
## Instructions
Let's start from your `Run` scheme with `main.swift` file
We could change it to this
```swift
import App
import Vapor
var env = try Environment.detect()
try LoggingSystem.bootstrap(from: &env)
let app = Application(env)
defer { app.shutdown() }
try app.setup(appBody).run()
```
Then let's switch to your `App` scheme where you have `configure.swift` and `routes.swift` files.
Let's rename `configure.swift` into `app.swift` which will look like this
```swift
import Vaporizer // it imports Vapor automatically
// Called before your application initializes.
@AppBuilder public var appBody: AppBuilder.Result {
// here we could place some wrapped configuration (read below)
ManualConfiguration { app in
// here we could place everything from old `configure.swift`
// but some parts could be rewritten declaratively (read below)
}
Routes {
// here we could place our routes declaratively (read below as well)
}
}
```
## Wrapped things
I've just started wrapping, so please join, pull requests are very welcome 😃
### Logger
```swift
@AppBuilder public var appBody: AppBuilder.Result {
// ...
Logger.level(.debug)
// ...
}
```
### HTTPServer
```swift
@AppBuilder public var appBody: AppBuilder.Result {
// ...
HTTPServer.hostname(env: "SERVER_HOST").port(env: "SERVER_PORT") // will read environment variables
// or
HTTPServer.hostname("192.168.0.1").port(8585)
// ...
}
```
### FileMiddleware
```swift
@AppBuilder public var appBody: AppBuilder.Result {
// ...
#if os(macOS) // don't use this middleware for production, please!
FileMiddleware() // by default to public
// or
FileMiddleware.publicDirectory("CustomDir")
#endif
// ...
}
```
### CORSMiddleware
```swift
@AppBuilder public var appBody: AppBuilder.Result {
// ...
CORSMiddleware
.allowedOrigin(.all)
.allowedMethods(.GET, .POST, .PUT, .OPTIONS, .DELETE, .PATCH)
.allowedHeaders(.accept, .authorization, .contentType, .origin, .xRequestedWith, .userAgent, .accessControlAllowOrigin)
.allowCredentials()
.exposedHeaders(...)
.cacheExpiration(...)
// ...
}
```
### Routes
It is my most desired thing, I just love to see the whole API beautifully described
Ok, so let's start rewriting your `routes.swift`
We have two things in `RouteBuilder`
- groups
- middlewares
Let's say that you have `let v1 = app.grouped("v1")` route group which is not protected, we could rewrite it this easy way
```swift
Group("v1") {
// subgroups or/and endpoints here
}
```
then maybe you have two more route groups inside `v1`, let's say `auth` which is obviously not protected and `profile` which is only for authorized users
```swift
Group("v1") {
Group("auth") {
// subgroups or/and endpoints here
}
Group("profile").protectedBy(AuthMiddleware()).routes {
// subgroups or/and endpoints here
}
}
```
Easy, right? 😜 Then let's move to endpoints declaration
With pure Vapor you may have endpoints for authorization declared this way
```swift
let v1 = app.grouped("v1")
let auth = v1.grouped("auth")
auth.post("signup") { req -> EventLoopFuture in
// ...
}
```
which could be easily rewritten this way
```swift
Group("v1") {
Group("auth") {
Post("signup") { req -> EventLoopFuture in
// ...
}
}
}
```
then for `profile` group
```swift
let profile = v1.grouped("profile").grouped(AuthMiddleware())
/// Gets current profile
profile.get(use: my) { req -> EventLoopFuture in
// ...
}
/// Updates profile info
profile.on(.PATCH, body: .collect(maxSize: .init(value: 1024 * 1024 * 20))) { req -> EventLoopFuture in
// ...
}
```
let's rewrite it into this
```swift
Group("v1") {
Group("profile") {
Get { req -> EventLoopFuture in
// ...
}
Patch(body: .collect(maxSize: .init(value: 1024 * 1024 * 20))) { req -> EventLoopFuture in
// ...
}
}
}
```
it looks good now, but I'm sure that you use some dedicated files for route groups (like route collections), so let's make it look better.
I propose you to create files something like this
`/Controllers/Auth/AuthController.swift`
```swift
struct AuthController {}
```
`/Controllers/Auth/Auth+Signup.swift`
```swift
extension AuthController {
static func signup(on req: Request) throws -> EventLoopFuture {
// ...
}
}
```
same for profile
`/Controllers/Profile/ProfileController.swift`
```swift
struct ProfileController {}
```
`/Controllers/Profile/Profile+Get.swift`
```swift
extension ProfileController {
static func get(on req: Request) throws -> EventLoopFuture {
// ...
}
}
```
`/Controllers/Profile/Profile+UpdatePhoto.swift`
```swift
extension ProfileController {
static func updatePhoto(on req: Request) throws -> EventLoopFuture {
// ...
}
}
```
#### And final result with that may look like this
```swift
@AppBuilder public var appBody: AppBuilder.Result {
// ...
Routes {
Get { "Hello dear stranger 😄" }
Group("v1") {
Group("auth").routes(AuthController.self) {
Post("signup", use: $0.signup)
}
Group("profile").protectedBy(AuthMiddleware()).routes(ProfileController.self) {
Get(use: $0.get)
Patch(body: .collect(maxSize: .init(value: 1024 * 1024 * 20)), use: $0.updatePhoto)
}
}
}
}
```
Isn't it beautiful? 😊
#### Some additional information about routes
You could build paths the same as with pure vapor using `:something`, `*`, and `**` cause it is just directly wrapped.
