shadow-dom-walk v1.0.4

Purpose

Sometimes you just wanna walk the DOM and find all the shadow roots and everything in the shadow roots

Getting Started

npm install shadow-dom-walk

API

findAllNodes

import { findAllNodes } from 'shadow-dom-walk'

// Max number of shadow roots to go down. Default is Infinity.
const maxShadowRootDepth = 3

// Container can be any Node
const container = document

findAllNodes(document, maxShadowRootDepth)

findAllElements

import { findAllElements } from 'shadow-dom-walk'

// Max number of shadow roots to go down. Default is Infinity.
const maxShadowRootDepth = 3

// Container can be any Element, DocumentFragment, or ShadowRoot
const container = document

findAllElements(document, maxShadowRootDepth)

Element / Node Order

Elements and Nodes are returned in the order they're discovered via a "depth-first" search.

Example:

<div>
    <my-custom-element>
      #shadowRoot
      <slot></slot>
    </my-custom-element>

    <my-other-custom-element>
      #shadowRoot
      <slot></slot>
    </my-other-custom-element>
</div>

Would produce an array like this:

[
  "div",

  // my-custom-element
  "my-custom-element",
  "ShadowRoot",
  "slot"

  // my-other-custom-element
  "my-other-custom-element",
  "ShadowRoot",
  "slot"
]
