Unlock the Power of Browser State Tracking with Tornis
When it comes to building exceptional user experiences, understanding how users interact with our websites is crucial. That’s where browser state tracking comes in – a game-changer for tailoring our components to fit various configurations. Among the many tools available, Tornis stands out as a minimal yet powerful JavaScript library that watches the state of your browser’s viewport, allowing you to respond to changes with ease.
What Sets Tornis Apart
While it’s possible to manually track everything using native JavaScript event handlers, Tornis offers significant advantages in terms of performance and coding experience. Its deferred approach ensures that your code only runs when there’s a change in the store, and when the browser is ready to render. This means a smoother, more efficient experience for users.
Getting Started with Tornis
To harness the power of Tornis, simply run the installation command in your project root. Since Tornis is written in modern JavaScript with ES6, you may need to transpile with Babel to support legacy browsers.
Tracking Browser States
Tornis currently tracks a range of states, including:
- Mouse position and cursor velocity
- Viewport size and scroll position
- Browser position and velocity relative to the screen
- Device orientation and pixel ratio
By subscribing to store updates, you can combine these values to create a wide range of effects.
A Practical Example: Cursor Velocity Tracking
Let’s create a simple component that tracks mouse cursor velocity using Tornis. Our goal is to render a dizzy emoji whenever the cursor is moved at high speed, capturing the velocity at the moment the emoji changes. With Tornis, this becomes a breeze.
Setup and Installation
To get started, ensure you’re working on a Babel-enabled project. Then, install Tornis using your package manager and import the necessary functions into your project. For this example, we’ll use Vue.js, but you can adapt the approach to your preferred framework.
Tracking State with Tornis
The heart of Tornis lies in its ability to track state changes. By passing a set of values to be updated, you can watch changes and act accordingly. In our example, we’ll track mouse velocity and leverage Vue’s reactivity to create an interactive experience.
Experience the Power of Tornis
With Tornis, you can unlock a new level of browser state tracking, enabling you to craft exceptional user experiences with ease. Whether you’re building parallax effects or cursor velocity tracking, Tornis is the perfect tool for the job.
