Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

node-window-polyfill

Version npm

Polyfill for the problem window is not defined in node.js. It's inserting window object on globals and inputing all needed sub-elements with requiring web sockets dependency.

Installation

Yarn

yarn add node-window-polyfill

Npm

npm install node-window-polyfill

Requirements

Minimum ES5.

To use it in different environment it's required to clone and build it with the proper flag.

Usage

Import it in global file, or in every file where the source code requires the window object.

import nodeWindowPolyfill from "node-window-polyfill";

nodeWindowPolyfill.register();

For shorter import that will call register directrly

import "node-window-polyfill/register";

If you don't want to import 'ws' module and just create empty objects:

import nodeWindowPolyfill from "node-window-polyfill";

nodeWindowPolyfill.register(false);

And the version previous ES versions:

require('node-window-polyfill').register();

What is polyfilled?

  • usage of window in the code or libraries
  • window.setTimeout - default setTimeout node function
  • window.clearTimeout - default clearTimeout node function
  • window.WebSocket - version from global object
  • window.ArrayBuffer - version from global object only
  • window.addEventListener - empty void function
  • window.navigator - { onLine: true }
  • window.isNodeJS - to check if polyfills were aplied
  • window.localStorage - in memory storage
  • window.Date - version from global object
  • global.WebSocket - using ws if the right flag is not set
  • if the above functions/properties are already set in the global object then they will be taken into the account

Configure

To configure development environment and run the tests, first clone the repository:

git clone https://github.com/tgorka/node-window-polyfill.git

then (once you have yarn and node installed) install dependencies

yarn

Build

To build the distribution and types

yarn build

The distribution is in the dist folder and types in the types folder.

To change defauld ES standard use --target flag. Ex.:

yarn build -target es3

Test

After configuring we can run tests.

yarn test

We can use debug information logging with setting up env variable

DEBUG=nodeWindowPolyfill-* yarn test
