Module Bonsai_web.Start

Start handles the entire lifecycle of web-based Bonsai application.

Put another way, Start is like Core.Command for Bonsai_web apps.

module Handle : sig ... end
module App_input : sig ... end

The input of an application-level component is a value of type ('input, 'outgoing) App_input.t.

module App_result : sig ... end

The result of an application-level component is a value of type 'incoming App_result.t. This value contains the view of the app, and also an inject function: a way for the holder of the Handle.t to send events into the application component.

Start functions

val start_standalone : initial_input:'input -> bind_to_element_with_id:string -> ('input, Bonsai_web__.Import.Vdom.Node.t) Bonsai_web__.Import.Bonsai.t -> ('input, unit, Core_kernel.Nothing.t, Core_kernel.Nothing.t) Handle.t

Start an application, receiving a handle that can't schedule any actions.

The outermost Bonsai.t's result type parameter should be a Vdom.Node.t, which will be bound to the DOM element with id bind_to_element_with_id.

val start : initial_input:'input -> bind_to_element_with_id:string -> (('input, 'outgoing) App_input.t, ('extra, 'incoming) App_result.t) Bonsai_web__.Import.Bonsai.t -> ('input, 'extra, 'incoming, 'outgoing) Handle.t

Start an application, receiving a handle that can schedule actions of a user-defined type.

The outermost Bonsai.t's result type parameter should be a pair consisting of:

  • a Vdom.Node.t, which will be bound to the DOM element with id bind_to_element_with_id; and
  • an inject function that accepts external actions and returns Vdom.Event.ts.
