conn

The Conn type carries the HTTP request, authenticated user, and assigns through every middleware and handler.

Types

pub type AuthUser {
  AuthUser(id: Int, username: String)
}

pub type Conn(body) {
  Conn(
    request: Request(body),
    auth: Option(AuthUser),
    assigns: Dict(String, String),
  )
}

Functions

new

pub fn new(req: Request(body)) -> Conn(body)

Wrap a raw request in a Conn with no auth and empty assigns. Called automatically by router.dispatch.

Working with Conn

Reading auth:

case c.auth {
  Some(user) -> user.username
  None -> "anonymous"
}

Writing assigns:

Conn(..c, assigns: dict.insert(c.assigns, "key", "value"))
