Module Naboris.ServerConfig

Module for configuring the naboris http server.

type 'sessionData t
type httpAfConfig = {
  1. read_buffer_size : int;
  2. request_body_buffer_size : int;
  3. response_buffer_size : int;
  4. response_body_buffer_size : int;
}
val create : unit -> 'sessionData t

Returns default config. Used as the starting place to build the config.

val setOnListen : (unit -> unit) -> 'sessionData t -> 'sessionData t

Create new config from t('sessionData) with the onListen function unit => unit.

onListen function is called once the server is created successfully.

val setSessionConfig : ?maxAge:int -> ?sidKey:string -> ?secret:string -> (string option -> 'sessionData Session.t option Lwt.t) -> 'sessionData t -> 'sessionData t

Creates new config from t('sessionData) with mapSession function option(string) => Lwt.t(option(Session.t('sessionData))).

mapSession function is called at the very beginning of each request/response lifecycle. Used to set session data into the Req.t('sessionData) for use later in the request/response lifecycle.

~maxAge Optional param to set max age for session cookies in seconds (defaults to 30 days) ~sidKey Optional param to set key for session cookies (defaults to "nab.sid") ~secret Optional param but recommended to set this to a secure string.

val setRequestHandler : (Route.t -> 'sessionData Req.t -> Res.t -> Res.t Lwt.t) -> 'sessionData t -> 'sessionData t

Creates new config from t('sessionData) with requestHandler (Route.t, Req.t('sessionData), Res.t) => Lwt.t(Res.t).

requestHandler is the main handler function for responding to incoming http requests.

val setErrorHandler : ErrorHandler.t -> 'sessionData t -> 'sessionData t

Creates new config from t('sessionData) with errorHandler ErrorHandler.t.

This configuration is optional and by default Res.reportError will respond with 500 and the text of the exn provided.

val setHttpAfConfig : httpAfConfig -> 'sessionData t -> 'sessionData t

Creates new config from t('sessionData) with httpAfConfig httpAfConfig.

val addMiddleware : 'sessionData Middleware.t -> 'sessionData t -> 'sessionData t

Creates nwe config from t('sessionData) with the added middleware Middleware.t('sessionData).

Middlewares are executed in the order they are added. The final "middleware" is the requestHandler.

val addStaticMiddleware : string list -> string -> 'sessionData t -> 'sessionData t

Creates a virtual path prefix list(string) and maps it to a local directory string.

Middlewares are executed in the order they are added. The final "middleware" is the requestHandler.

val setStaticCacheControl : string option -> 'sessionData t -> 'sessionData t

Set Cache-control header value which is returned with every request for a static file.

If None then Cache-control header is omitted.

val sessionConfig : 'sessionData t -> 'sessionData SessionConfig.t option

Returns SessionConfig.t('sessionData) from config. None if none is configured.

val setStaticLastModified : bool -> 'sessionData t -> 'sessionData t

Set bool flag which true signals the server to send Last-Modified headers with static file responses.

val staticLastModified : 'sessionData t -> bool

Returns bool from config, which true signals the server to send Last-Modified headers with static file responses.

val setEtag : Etag.strength option -> 'sessionData t -> 'sessionData t

Set option([`Storng | `Weak]) which signals the server to set etags as strong or weak. None will set no etag headers.

val etag : 'sessionData t -> Etag.strength option

Returns currently configured etag header strength.

val middlewares : 'sessionData t -> 'sessionData Middleware.t list

Returns list of middlewares from the config.

val onListen : 'sessionData t -> unit -> unit

Returns onListen function of t.

val routeRequest : 'sessionData t -> Route.t -> 'sessionData Req.t -> Res.t -> Res.t Lwt.t

Returns routeRequest function of t.

val errorHandler : 'sessionData t -> ErrorHandler.t option

Returns option(ErrorHandler.t) of t.

val httpAfConfig : 'sessionData t -> Httpaf.Config.t option

Returns option(HttpAf.Config.t) of t.

val staticCacheControl : 'sessionData t -> string option

Returns staticCacheControl value of t.
