tsParticles Firefly Preset

tsParticles preset for a mouse trail made with small fading particles like little fireflies.

Sample

Quick checklist

1. Install @tsparticles/engine (or use the CDN bundle below)
2. Call loadFireflyPreset(tsParticles) before tsParticles.load(...)
3. Set preset: "firefly" in options

How to use it

CDN / Vanilla JS / jQuery

<script src="https://cdn.jsdelivr.net/npm/@tsparticles/preset-firefly@3/tsparticles.preset.firefly.bundle.min.js"></script>

Usage

Once the scripts are loaded you can set up tsParticles like this:

(async () => {
  await loadFireflyPreset(tsParticles);

  await tsParticles.load({
    id: "tsparticles",
    options: {
      preset: "firefly",
    },
  });
})();

Customization

Important ⚠️ You can override all the options defining the properties like in any standard tsParticles installation.

tsParticles.load({
  id: "tsparticles",
  options: {
    particles: {
      shape: {
        type: "square", // starting from v2, this require the square shape script
      },
    },
    preset: "firefly",
  },
});

Like in the sample above, the circles will be replaced by squares.

Frameworks with a tsParticles component library

Checkout the documentation in the component library repository and call the loadFireflyPreset function instead of loadFull, loadSlim or similar functions.

The options shown above are valid for all the component libraries.

Dependencies

This preset loads and combines the following packages:

Package	Role in this preset	README
@tsparticles/basic	Base runtime bundle used by the preset	https://www.npmjs.com/package/@tsparticles/basic
@tsparticles/engine	tsParticles engine and preset registration	https://www.npmjs.com/package/@tsparticles/engine
@tsparticles/interaction-external-trail	Adds pointer-driven trail interaction	https://www.npmjs.com/package/@tsparticles/interaction-external-trail
@tsparticles/plugin-interactivity	Enables external interaction plumbing	https://www.npmjs.com/package/@tsparticles/plugin-interactivity
@tsparticles/updater-life	Controls particle life-cycle stages	https://www.npmjs.com/package/@tsparticles/updater-life

If you want to customize one specific behavior, start from the related package README above.

Common pitfalls

• Calling tsParticles.load(...) before loadFireflyPreset(tsParticles)
• The effect relies on mouse movement; on touch-only devices it may not appear without additional interaction setup
• The preset uses a transparent background; set background.color if you need a solid backdrop
