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 🙏

TypeScript types for new JavaScript

This repository contains TypeScript type definitions for a lot of new JavaScript stuff that isn't yet in TypeScript's standard type definitions (see below for the complete list). These range from the File System Access API over View Transitions to View Transitions or Handwriting Recognition. Some specifications have only partially been integrated into TypeScript's standard type declarations, in which case this repository contains only the parts of the specifications that aren't there (yet). For most specifications I have used WebIDL2TS, a tool that automatically converts WebIDL to TypeScript type definitions, and manually edited the stuff where it didn't generate the desired result.

Also take a look Better-TypeScript, which contains various TypeScript type definitions to make working with TypeScript more convenient.

NPM: new-javascript

GitHub: BenjaminAster/TypeScript-types-for-new-JavaScript

Install using npm:

npm i -D new-javascript@latest

Reference the type definitions directly in your TypeScript/JavaScript files...

/// <reference types="new-javascript" />

...or include them in your tsconfig.json or jsconfig.json:

{
	"compilerOptions": {
		"types": ["new-javascript"],
	},
}

Since combining web worker scripts and scripts running on the main thread in one project is rather difficult in TypeScript by default, all worker-exclusive interfaces (e.g. FileReaderSync, FileSystemSyncAccessHandle) are included by default in this package (see worker.d.ts). For service worker and shared worker types, see Better-TypeScript.

For worklets, use new-javascript/worklet/<WORKLET_NAME> as the path:

/// <reference types="new-javascript/worklet/audio" />
/// <reference types="new-javascript/worklet/paint" />
/// <reference types="new-javascript/worklet/layout" />
/// <reference types="new-javascript/worklet/animation" />
