As a Shopify theme gets more fully featured, it is likely that large amounts of JavaScript are being used to improve and expand the user experience. Making theme changes gets more nerve wracking as the amount of code increases. Did my sales go down because I broke something with the last JavaScript change? If you’re worried about that next theme publish, it’s time to start monitoring user experiences for JavaScript errors. TrackJS makes error monitoring quick and easy to do!

TrackJS is the best frontend error monitoring tool. It’s all we do and we do it well. To keep it simple we have just two different JavaScript agents. One for the browser, and one for Node server environments. That’s it. No other languages or platforms are supported. Just JavaScript.

TrackJS started ten years ago. To date, the only funding TrackJS ever received was the initial founder investment of $4,500 dollars (a whopping $1,500 per founder). Today, you’d call us a “bootstrapped” business. We’re proud of that fact. It means there’s no outside investors. No one to make us build a product we don’t want to build. And no one that can pull the plug if the growth chart doesn’t look like a hockey stick.

You have so many options for frontend error monitoring today, and they all do slightly different things. We looked at everyone and did a breakdown of the most important features for frontend, the problems developers run into, end user reviews, and pricing structures to see how the best vendors stack up.

A few days ago a memo from logistics company Flexport leaked to the media announcing significant layoffs. Now, a tech company doing layoffs in 2023 is hardly notable. A 20% RIF here and there is almost expected. What is notable is the reason for the layoffs: Flexport is trying to achieve profitability.

Alerts and notifications have been part of TrackJS since the very beginning. Our standard notification options reflect our desire to keep things simple. Over time though, our customers have asked to customize their alerts and fine tune them to specific scenarios. To support that use case, we’re releasing a new kind of notification we’re calling “Saved Filter Notifications”.

As JavaScript has grown more prevalent on the web, so have JavaScript errors. As an error monitoring service, we have a unique perspective on how errors impact the web globally, and we are constantly learning more about how the web breaks. We’re thrilled to share this report today so we can all understand it better, and build a better web. We produce this report every week, you can check it out anytime via the free Global Error Statistics report.

Large tech companies are monetizing and exploiting customer data in increasingly unpalatable ways. It’s no surprise that users are fighting back. It’s estimated between 25% and 50% of users are employing ad blockers. Unfortunately, some overzealous ad blocking tools have added TrackJS domains to their block lists. We believe the blocks are unwarranted (more below). We don’t sell or monetize our user data. Ever.

Release 3.8.0 of the TrackJS browser agent added support for Web Workers, which adds some awesome new observability to the background tasks of your web applications. Many development teams have adopted Web Workers to their web applications to add offline support, caching, or to process heavy tasks. Workers allow web apps to feel faster by removing work from the user interface thread.
