jquery or cheerio

// return jquery or cheerio
let $ = createJSDOM().$;
$(':root').length;

createJSDOM

with create jsdom with extra prototype

export interface IJSDOM extends JSDOM {
    $: JQueryStatic;
    url: URL;
    document: Document;
    _options: IJSDOM_Symbol_Options;
    fakeThen<T>(cb: (jsdom: IJSDOM) => T): T;
}

export declare function createJSDOM(html?: string | Buffer | BinaryData, options?: IConstructorOptions): IJSDOM;

fake Promise then

// fake .then, not realy Promise, still is sync
createJSDOM().fakeThen(function (jsdom)
{
	console.log(jsdom._options);
});

asyncJSDOM / Promise

asyncJSDOM().then(function (jsdom)
{
	console.log(jsdom._options);
});

packJSDOM(jsdom: JSDOM): IJSDOM

pack any jsdom object with extra

import { JSDOM } from 'jsdom';
import { packJSDOM } from 'jsdom-extra';

let jsdom2 = new JSDOM();

// will overwrite jsdom2 too
packJSDOM(jsdom2) // => return jsdom2

fromURL

• API: fromURL

allow use POST on fromURL

function fromURL(url: string, options?: IFromUrlOptions): Promise<IJSDOM>

export interface IFromUrlOptions extends Partial<FromUrlOptions & IOptionsJSDOM>
{
	requestOptions?: Partial<IRequestOptions>,
	cookieJar?: ICookieJar,
}

export interface IRequestOptionsJSDOM
{
	resolveWithFullResponse: boolean;
	encoding: null;
	gzip: boolean;
	headers: {
		"User-Agent": string;
		Referer: string;
		Accept: string;
		"Accept-Language": string;
	};
	jar: IRequestJar;
}

export interface IRequestOptions extends Partial<IRequestOptionsJSDOM>
{
	method?: 'POST' | 'GET' | string,
	form?: {
		[key: string]: any,
		[key: number]: any,
	},
}

fromFile

function fromFile(url: string, options?: IFromFileOptions): Promise<IJSDOM>

get the finally options that use on create JSDOM

createJSDOM()._options.ConstructorOptions

output

   { windowOptions: 
      { url: 'about:blank',
        referrer: '',
        contentType: 'text/html',
        parsingMode: 'html',
        userAgent: 'Mozilla/5.0 (win32) AppleWebKit/537.36 (KHTML, like Gecko) jsdom/11.6.2',
        parseOptions: [Object],
        runScripts: undefined,
        encoding: 'UTF-8',
        pretendToBeVisual: false,
        virtualConsole: [VirtualConsole],
        cookieJar: [CookieJar] },
     resources: undefined,
     beforeParse: [Function] }

lazy overwrite / require

will overwrite global JSDOM

import JSDOM from 'jsdom-extra/auto';
const JSDOM = require("jsdom-extra/auto").JSDOM;

globalJsdom

same as jsdom-global, but with

function globalJsdom<T>(html?, options: Partial<T & IConstructorOptions & IOptions> = {})

create

require("jsdom-extra/global")()

const globalJsdom = require("jsdom-extra/global");
globalJsdom();

let ret: {
       jsdom: IGlobalJSDOM;
       window: DOMWindow;
       document: Document;
       cleanup: () => void;
   };

ret = globalJsdom();

cleanup

ret.cleanup();
ret.jsdom.cleanup();

Mocha

Simple: Use Mocha's --require option. Add this to the test/mocha.opts file (create it if it doesn't exist)

mocha --require jsdom-extra/lib/global/register

Advanced: For finer control, you can instead add it via mocha's before and after hooks.

before(function () {
  this.globalJsdom = require('jsdom-extra/global')()
})

after(function () {
  this.globalJsdom.cleanup()
})
