[tsParticles](https://github.com/tsparticles/tsparticles) updater plugin for opacity animations.

## 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.updater.opacity.min.js` file will export the function to load the updater plugin:

```javascript
loadOpacityUpdater;
```

### Usage

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

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

  await tsParticles.load({
    id: "tsparticles",
    options: {
      /* options */
    },
  });
})();
```

### ESM / CommonJS

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

```shell
$ npm install @tsparticles/updater-opacity
```

or

```shell
$ yarn add @tsparticles/updater-opacity
```

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

```javascript
const { tsParticles } = require("@tsparticles/engine");
const { loadOpacityUpdater } = require("@tsparticles/updater-opacity");

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

or

```javascript
import { tsParticles } from "@tsparticles/engine";
import { loadOpacityUpdater } from "@tsparticles/updater-opacity";

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

## Option mapping

- Primary options key: `particles.opacity`

```json
{
  "particles": {
    "opacity": {}
  }
}
```

## Common pitfalls

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