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.

Zone.js

Implements Zones for JavaScript, inspired by Dart.

If you're using zone.js via unpkg please provide a query param ?main=browser
https://unpkg.com/zone.js?main=browser
If you're using the following library, make sure you import them first

'newrelic' as it patches global.Promise before zone.js does
'async-listener' as it patches global.setTimeout, global.setInterval before zone.js does
'continuation-local-storage' as it uses async-listener

NEW Zone.js POST-v0.6.0

See the new API here.

Read up on Zone Primer.

What's a Zone?

A Zone is an execution context that persists across async tasks. You can think of it as thread-local storage for JavaScript VMs.

See this video from ng-conf 2014 for a detailed explanation:

vizone - control flow visualizer that uses zone.js

Standard API support

zone.js patched most standard web APIs(such as DOM events, XMLHttpRequest...) and nodejs APIs (EventEmitter,fs ...), for more details, please see STANDARD-APIS.md for more details.

Non standard API support

And now we are adding support to some non standard APIs, such as MediaQuery, Notification. Please see NON-STANDARD-APIS.md for more details.

Modules

zone.js patches the async APIs which described above, but those patch will have some overhead, from zone.js v0.8.9, you can choose which web API module you want to patch, for detail, please see MODULE.md for more details.
