[tsParticles](https://github.com/tsparticles/tsparticles) additional shadow effect.

## Quick checklist

1. Install `@tsparticles/engine` (or use the CDN bundle below)
2. Call the package loader function(s) before `tsParticles.load(...)`
3. Apply the package options in your `tsParticles.load(...)` config

## How to use it

### CDN / Vanilla JS / jQuery

The CDN/Vanilla version JS has one required file in vanilla configuration:

Including the `tsparticles.effect.shadow.min.js` file will export the function to load the effect:

```text
loadShadowEffect
```

### Usage

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

```javascript
(async () => {
  await loadShadowEffect(tsParticles);

  await tsParticles.load({
    id: "tsparticles",
    options: {
      /* options */
      /* here you can use particles.effect.type: "shadow" */
    },
  });
})();
```

### ESM / CommonJS

This package is compatible also with ES or CommonJS modules, firstly this needs to be installed, like this:

```shell
$ npm install @tsparticles/effect-shadow
```

or

```shell
$ yarn add @tsparticles/effect-shadow
```

Then you need to import it in the app, like this:

```javascript
const { tsParticles } = require("@tsparticles/engine");
const { loadShadowEffect } = require("@tsparticles/effect-shadow");

(async () => {
  await loadShadowEffect(tsParticles);
})();
```

or

```javascript
import { tsParticles } from "@tsparticles/engine";
import { loadShadowEffect } from "@tsparticles/effect-shadow";

(async () => {
  await loadShadowEffect(tsParticles);
})();
```

## Option mapping

- Effects are usually enabled through dedicated package loaders and effect-specific options.
- Package scope: `shadow`
- Start from the usage snippet in this README, then merge with your main options object incrementally.

## Common pitfalls

- Calling `tsParticles.load(...)` before `loadShadowEffect(...)`
- Verify required peer packages before enabling advanced options
- Change one option group at a time to isolate regressions quickly
