dom-node-predicates

Predicate functions for testing DOM nodes

Works with window.document, JSDOM, anything else that implements the DOM

npm install @mojule/dom-node-predicates

const predicates = require( '@mojule/dom-node-predicates' )
const something = require( './path/to/something/to/test' )

if( !predicates.node( something ) ){
  console.warn( 'something is not a DOM node!' )
}

if( predicates.element( something ) ){
  console.log( 'something is a DOM element' )
}

// etc.

export declare const element: (value: any) => value is Element;
export declare const processingInstruction: (value: any) => value is ProcessingInstruction;
export declare const text: (value: any) => value is Text;
