Introducing HotFX: A Standalone Web Component for Elegant Number Animations
In the evolving landscape of web development, leveraging modern, lightweight solutions is essential to create engaging user interfaces. One such innovation is the growth of vanilla JavaScript web components—self-contained, reusable elements that enhance functionality without relying on external frameworks.
Recently, I expanded this ecosystem by developing a new web component designed to animate numerical values seamlessly, reminiscent of the animated counters commonly seen on landing pages for SaaS products and digital services. This component, part of the HotFX project, exemplifies simplicity and efficiency.
About the HotFX Number Counter Web Component
The core functionality of this component is straightforward: it animates numbers counting up from zero (or any starting point) to a specified target value. Whether used to showcase statistics, milestones, or key metrics, this animated counter adds a dynamic visual appeal to your website.
Key Features:
- Zero Dependencies: The component relies solely on vanilla JavaScript, ensuring optimal performance and easy integration.
- Size Efficiency: The minified and gzipped version clocks in at approximately 1KB, making it suitable even for performance-critical applications.
- Ease of Use: Incorporating the component into your project is as simple as adding a single line of code and wrapping your number within the custom element.
How to Use
To implement the HotFX counter, simply include the component from NPM in your project and embed it wherever needed:
html
<hotfx-counter>42</hotfx-counter>
Upon rendering, the number will animate smoothly from zero to the specified value, creating an engaging visual effect.
Behind the Scenes: How It Works
The animation logic employs JavaScript’s requestAnimationFrame() to achieve fluid motion. An easing function ensures that the numbers accelerate and decelerate naturally, enhancing visual polish. For developers interested in the internal workings, the complete source code is openly available, providing insights into the implementation and facilitating customization.

Future Plans and invitations
HotFX is an ongoing project with plans to release new web components weekly. The goal is to build a versatile library that empowers developers to craft sleek, interactive interfaces with minimal overhead.
I welcome suggestions and requests for additional components—if there’s a specific feature or animation effect you’d like to see, please let me know!
