Vapor integration

[daniele99999999]

I just find this library and i would like to test it. There is somewhere an example of a Vapor integration?

There isn't any special Vapor integration. You would use the library like normal. If you're using Vapor, a simple route would look something like this for GET /html:

app.on(.GET, ["html"]) { (request) -> String in
    return #html {
        html {
            body {
                h1("Hello World!")
            }
        }
    }
}

i tried like that way, it doesn't work: in the browser appear a string withn html code on it :)
I'm a novice in server side, so i just start to check vapor few days ago. I see that in the closure i have to return an ResponseEncodable/AsyncResponseEncodable, that have a method needed for protocol conformance:

encodeResponse(for request: Request)

returning a Response

for Html i did some experiment and i was able to add something working in this way:

var headers = HTTPHeaders()
        headers.add(
            name: .contentType,
            value: "text/html"
        )
        return .init(
            status: .ok,
            headers: headers,
            body: .init(string: render())
        )

So i create a protocol HTMLResponse like that:

protocol HTMLResponse: AsyncResponseEncodable {
    func render() -> String
}

extension HTMLResponse {
    public func encodeResponse(for request: Request) async throws -> Response {
        var headers = HTTPHeaders()
        headers.add(
            name: .contentType,
            value: "text/html"
        )
        return .init(
            status: .ok,
            headers: headers,
            body: .init(string: render())
        )
    }
}

The html page:

struct SwiftHtmlkitView: HTMLResponse {
    func render() -> String {
        #html(
          div(
            p("welcome to ozzyoga.milano!")
          )
        )
    }
}

and in the controller/routes:

 @Sendable
    func index(req: Request) async throws -> SwiftHtmlkitView {
        return SwiftHtmlkitView()
    }

Sure there is many things i miss for doing everything in a proper and good way, but the most annoying is that i cannot return an any HTMLResponse but only a concrete type

Type 'any HTMLResponse' cannot conform to 'AsyncResponseEncodable'
Only concrete types such as structs, enums and classes can conform to protocols

Do you have some suggestion about how to proceed from that?

Regarding it showing up as raw text in a browser: you would need to make sure the headers have the proper content type so it would show up correctly (which is what you mentioned you had to do).

---

ResponseEncodable/AsyncResponseEncodable are part of Vapor which is not within this project's scope. Their implementation detail requires the use of a concrete type when using the routes builder.

You should probably ask for help in their Discord server (https://discord.gg/vapor) to guide you to a solution.
