frost-react: Instant Snowfall for React

Every December, every product launch, every fun landing page, I kept running into the same tiny problem:

"I just want a clean snowfall effect in my React app… why is this so complicated?"

That frustration is exactly why I built frost-react.

frost-react is a lightweight, accessible and customizable snowfall animation component for React, designed to be simple to use, performant, and pleasant for both developers and users.

What is frost-react?

frost-react is an npm package that gives you a <Snowfall /> React component. Drop it into your app and you instantly get a smooth snowfall animation. No canvas setup, no animation math, no performance headaches.

It's built with:

• ⚛️ React
• 🧠 TypeScript
• ⚡ performance-first defaults
• ♿ accessibility in mind
• 📦 zero runtime dependencies (besides React)

• GitHub: https://github.com/gimnathperera/frost-react
• npm: https://www.npmjs.com/package/frost-react

Why I built this library

1. Existing solutions felt like overkill

Most animation libraries are either extremely generic (you still have to build the snowfall logic yourself) or heavy and over-engineered for something that's purely visual.

I wanted something that feels like <Snowfall />. No config required unless you want it.

2. Performance matters, especially on mobile

Snowfall is purely decorative. It should never make your app feel slow.

frost-react:

• automatically reduces the flake count on mobile,
• avoids unnecessary re-renders,
• keeps animations smooth on low-powered devices.

You still get full control, but the defaults are safe.

3. Accessibility should not be optional

Many users prefer reduced motion. frost-react respects prefers-reduced-motion, uses clean layering with z-index, and ships with non-intrusive defaults that don't block interaction.

Under the hood, the README spells out exactly what that means: the snow layer is marked aria-hidden="true" so screen readers ignore it, and it uses pointer-events: none so clicks go straight through to your UI.

Animation should enhance UX, not harm it.

Installation and quick start

Install it like any normal npm package:

npm install frost-react

Use it in your app:

import { Snowfall } from "frost-react";
 
export default function App() {
  return (
    <>
      <Snowfall />
      <main>Your app content</main>
    </>
  );
}

That's it. You now have snowfall. ❄️

Customization without the pain

Tweak the animation easily through props:

<Snowfall
  flakeCount={120}
  wind={[-30, 30]}
  speed={[6, 14]}
  size={[12, 28]}
  opacity={[0.5, 0.9]}
  color="#ffffff"
/>

Range props like speed, size, opacity and wind accept either a single number or a [min, max] pair, so you can give the snow some natural variation instead of every flake looking identical.

Available props

All props are fully typed with TypeScript. The full list with types and defaults lives in the Props API section of the README.

A few handy recipes

Only show snow in December:

import { Snowfall } from "frost-react";
 
const isDecember = new Date().getMonth() === 11;
 
export function SeasonalSnow() {
  return <Snowfall enabled={isDecember} />;
}

Swap the flake for your own character:

<Snowfall snowflakeCharacter="❅" flakeCount={60} />

Turn off the automatic mobile reduction (or just set flakeCount explicitly, which overrides it):

<Snowfall useMobileDetection={false} />

Prefer to import the CSS yourself instead of relying on automatic injection:

import "frost-react/style";
import { Snowfall } from "frost-react";

Works with modern React frameworks

frost-react plays nicely with modern setups:

• Next.js (SSR safe)
• Remix
• Vite
• CRA
• ESM and CommonJS

No window crashes on the server. No hacks.

Developer experience matters

• Full TypeScript support and a clean internal architecture
• A Storybook playground for testing
• Sensible defaults with escape hatches
• Zero unnecessary dependencies

If you want to play with every prop combination locally, clone the repo and run Storybook:

npm install
npm run storybook

Small library. Clean responsibility.

When should you use frost-react?

• Holiday landing pages or seasonal UI flair
• Marketing sites and fun dashboards
• Temporary events (Christmas, New Year, winter promos)

If you want joy without bloat, this fits.

Wrapping up

frost-react exists because I wanted a snowfall effect that looks good, performs well, respects users, and doesn't fight developers. It's intentionally small, focused and opinionated, in a good way.

Key takeaways

• One line to get started: <Snowfall /> works with zero config.
• Safe defaults: fewer flakes on mobile, reduced motion respected, no blocked clicks.
• Customizable when you need it: ranges for speed, size, opacity and wind, plus your own character and color.
• Framework-friendly: SSR safe, ESM and CommonJS, fully typed.

If you try it out, break it, improve it, or build something fun with it, I'd love to see it.

Happy coding, Gimnath ❄️
