Module Snabbdom_data

module Snabbdom_data: sig .. end

The Data module provides functions for interacting with the data object passed to snabbdom's h function.

type t

Represents a Snabbdom data object.

Essentially this is just a standard JavaScript object. For example:

{
    style: {
        color: '#000',
        'font-weight': 'bold'
    },
    on: {
        click: function(e) { e.preventDefault() }
    }
}

val empty : unit -> t

Return a new, empty Snabbdom data object. This is equivalent to JavaScript {}

val set_in_path : t -> string array -> 'a -> t

Sets an object property somewhere in the data object.

Pass an array of strings representing the path to the property to be set, followed by the property value. Intermediate objects will be created if they don't already exist.

For example, to add a property like the following (in JavaScript):

{ style: { color: '#000' } }

Use:

let data = set_in_path data [|"style"; "color"|] "#000"
