You can hardly even talk about web development without mentioning JavaScript. Because of its popularity, JavaScript has given birth to several frameworks and libraries that developers can barely keep up with. This post will discuss two popular JavaScript front-end frameworks and libraries: Svelte vs React and their performance. We’ll determine if Svelte is faster than React or whether Svelte is better than React. We’ll also compare the two to determine which is better for performance.

First Input Delay (FID) measures how long the browser took to respond to the first user input event. It’s one of several Core Web Vital metrics that measure how real users perceive the performance of modern web applications. New measurements like First Input Delay are increasingly important as JavaScript and SPA’s do more work on the client side.

Redis is fast. It’s fast because the data is all in memory. Persistence options are limited. Because of this, many people say, “Redis is for transient data only!” However, sometimes the need for speed and ease of operations can outweigh the durability downsides! In this talk, we look at a real SaaS business using Redis as its (only) datastore. You’ll learn why we decided to go all-in on Redis and the challenges we faced. You’ll learn how we operationalized the setup, handle backups and restores, and how we’ll scale out. Are we making a terrible mistake? You be the judge!

Javascript build chains have gotten outrageously complicated. Let's create one that isn't. Request Metrics monitors how real users experience the performance of your production websites. We need a JavaScript agent to pull performance data out of the browser. Watch as I calmly Bob Ross my way to a Webpack-free Typescript build pipeline with just a few NPM packages.

The easiest way to monitor your web performance. Request Metrics records how real users experience your website and shows you simplified metrics and alerting. And at a price that's easy on your budget.

Request Metrics is website performance monitoring, simplified for small teams. It's not a expensive APM "solution" or a complex query language to learn. Request Metrics is simply the key metrics you need to know to keep your website running fast and your customers happy.

Request Metrics was developed by TrackJS partners Todd Gardner, Eric Brandes, and Jordan Griffin. It was developed "in the open", with coding sessions and planning meetings recorded and broadcast on YouTube. They can be found at

Our Features:

  • Monitor Performance From Real Users: We gather metrics from real users visiting your website and aggregate their experience to show you the performance that really matters.
  • Measure Your Performance Over Time: We rollup your performance statistics to minutes, hours, and days so you can understand how you compare to last week, last month, or last year.
  • Know When Your Website Slows Down: When something is slowing down and your users are frustrated, we'll let you know with a detailed alert report about what's happening and the impact.
  • Worth The Price: No suite of tools to deploy, training to attend, or budget approvals. We show you the most important performance metrics you need, simplified, at a price that fits any team's budget.

Your Website, Faster.
