Create Node Window|Document|Global Mocks

Useful for Angular Universal projects or any JS applications doing SSR where window|document|global objects may be used in Node.

Installation

Install & save the library to your package.json:

$ npm i -S @devhelponline/create-node-mocks

Useage

Within your main Node file (regardless of framework)

import { createNodeMocks } from '@devhelponline/create-node-mocks';
import { readFileSync } from 'fs';
import { join } from 'path';

// Grab your index.html Template for us to create a Domino wrapper around
// In this case, we're grabbing it for an Angular-CLI 6+ project
const template = readFileSync(join(DIST_FOLDER, 'ANGULAR_CLI_PROJECT_NAME', 'index.html')).toString();

createNodeMocks(template);

Voila, common window|document errors will gone. Make sure to always wrap these around a test to determine whether this is a Server environment, and ignore them.

Add custom Window or (Node) Global mocks

import { createNodeMocks, IMock } from './node-mocks';
import { readFileSync } from 'fs';
import { join } from 'path';

const template = readFileSync(join(DIST_FOLDER, 'ANGULAR_CLI_PROJECT_NAME', 'index.html')).toString();

const noop = () => {};

// Window Mocks
const additionalWindowMocks: IMock = {
  alert: () => {},
  someWindowObject: {}
};

// Node Global Mocks
// In this example we want to add a few jQuery mocks
const nodeGlobalMocks: IMock = {
  jQuery: () => {
    return {
      addClass: noop,
      removeClass: noop,
      remove: noop,
      click: noop,
      html: noop
    };
  }
};

createNodeMocks(template, additionalWindowMocks, nodeGlobalMocks);
