### Position Plugin Setup Function

Source: https://next.neodrag.dev/docs/react/plugin/position

Illustrates the `setup` function within the position plugin, showing how it handles initial positioning when not interacting.

```APIDOC
## Position Plugin Setup

### Description
This section details the `setup` function of the position plugin, which is responsible for setting the initial or forced position of an element.

### Method
`setup(ctx)`

### Parameters
#### Path Parameters
- **ctx** (object) - The context object provided to the setup function, containing methods like `isInteracting` and `setForcedPosition`, and properties like `offset`.

### Logic
1. Checks if the element is currently being interacted with (`!ctx.isInteracting`).
2. Determines the target `x` and `y` coordinates using `options?.current` or `options?.default`, falling back to `ctx.offset` if not provided.
3. If the determined coordinates differ from the current offset (`ctx.offset.x`, `ctx.offset.y`), it calls `ctx.setForcedPosition(x, y)` to update the element's position.

### Request Example
```javascript
setup(ctx) {
  if (!ctx.isInteracting) {
    const x = options?.current?.x ?? options?.default?.x ?? ctx.offset.x;
    const y = options?.current?.y ?? options?.default?.y ?? ctx.offset.y;

    if (x !== ctx.offset.x || y !== ctx.offset.y) {
      ctx.setForcedPosition(x, y);
    }
  }
}
```
```

--------------------------------

### Maintain Plugin State with JavaScript

Source: https://next.neodrag.dev/docs/react/plugin/introduction

    return {
      startTime: null,
      moveCount: 0,
    };
  },

  start(ctx, state, event) {
    state.startTime = Date.now();
    state.moveCount = 0;
  },

  drag(ctx, state, event) {
    state.moveCount++;
    console.log(`Move #${state.moveCount}`);
  },

  end(ctx, state, event) {
    const duration = Date.now() - state.startTime;

### Vue Event Handling: Neodrag v2

Source: https://next.neodrag.dev/docs/vue/migration/v2-v3

Shows how to handle drag events in Neodrag v2 using the options object. This example logs drag start, drag, and drag end events with their respective offsets.

```javascript
<script setup>
const options = {
  onDragStart: ({ offsetX, offsetY }) =>
    console.log('start', offsetX, offsetY),
  onDrag: ({ offsetX, offsetY }) =>
    console.log('drag', offsetX, offsetY),
  onDragEnd: ({ offsetX, offsetY }) =>
    console.log('end', offsetX, offsetY),
};
</script>
```

--------------------------------

### Basic Dragging Example: v2 Options vs v3 Plugins (Vanilla JS)

Source: https://next.neodrag.dev/docs/vanilla/migration/v2-v3

Demonstrates the difference in basic usage for Neodrag's vanilla JavaScript package between v2 and v3. V2 uses a single options object, while v3 utilizes an array of plugins for configuration.

```javascript
import { draggable } from '@neodrag/vanilla';

const element = document.getElementById('drag-me');
const { destroy } = draggable(element, {
  axis: 'x',
  bounds: 'parent',
  grid: [10, 10],
  onDrag: (data) => console.log(data),
});
```

```javascript
import {
  Draggable,
  axis,
  bounds,
  BoundsFrom,
  grid,
  events,
} from '@neodrag/vanilla';

const element = document.getElementById('drag-me');
const instance = new Draggable(element, [
  axis('x'),
  bounds(BoundsFrom.parent()),
  grid([10, 10]),
  events({ onDrag: (data) => console.log(data) }),
]);
```

--------------------------------

### Basic Usage with Bounds

```APIDOC
## Basic Usage

### Description

This section shows how to apply the `bounds` plugin to restrict draggable elements to the viewport or their parent container.

### Method

Use the `v-draggable` directive with the `bounds` plugin configured via `BoundsFrom` utilities.

### Example

```vue
<script setup>
import { bounds, BoundsFrom, vDraggable } from '@neodrag/vue';
</script>

<template>
  <div>
    <div v-draggable="[bounds(BoundsFrom.viewport())]">
      Can't leave the screen
    </div>
    <div class="container">
      <div v-draggable="[bounds(BoundsFrom.parent())]">
        Contained child
      </div>
    </div>
  </div>
</template>

<style>
.container {
  position: relative;
  width: 300px;
  height: 300px;
  border: 2px solid blue;
}
</style>
```
```

### Analytics Integration with stateMarker and SolidJS

Source: https://next.neodrag.dev/docs/solid/plugin/statemarker

This SolidJS example shows how to integrate drag event data with an analytics service using the `stateMarker` plugin. It captures drag start and end events, sending relevant data such as element ID, drag count, and position to an analytics tracking function.

```javascript
import { createSignal } from 'solid-js';
import { stateMarker, events, useDraggable } from '@neodrag/solid';

function AnalyticsExample() {
  const [element, setElement] = createSignal<HTMLElement | null>(
    null,
  );

  const trackDragAnalytics = (eventName: string, data: any) => {
    // Send to analytics service
    analytics.track(eventName, {
      elementId: data.rootNode.id,
      dragCount: data.rootNode.getAttribute('data-neodrag-count'),
      position: data.offset,
      timestamp: Date.now(),
    });
  };

  useDraggable(element, [
    stateMarker(),
    events({
      onDragStart: (data) => trackDragAnalytics('drag_started', data),
      onDragEnd: (data) => trackDragAnalytics('drag_completed', data),
    }),
  ]);

  return <div ref={setElement}>Analytics-tracked element</div>;
}
```

--------------------------------

### Neodrag: Performance Optimization for Dynamic Controls

Source: https://next.neodrag.dev/docs/react/plugin/controls

Optimize Neodrag performance when using dynamic control zones by carefully managing when zones are recomputed. Avoid recomputing on every drag event if possible. Prefer recomputing only during 'setup' or 'start' hooks, or use static zones for the best performance.

```javascript
// ❌ Expensive - queries DOM on every drag event
controls(
  {
    allow: ControlFrom.selector('.complex-selector:nth-child(odd)'),
  },
  (ctx) => ctx.hook === 'drag',
);

// ✅ Better - cache zones, only recompute when needed
controls(
  {
    allow: ControlFrom.selector('.handle'),
  },
  (ctx) => {
    // Only recompute if DOM structure might have changed
    return ctx.hook === 'setup' || ctx.hook === 'start';
  },
);

// ✅ Best - static zones for better performance
controls({ 
  allow: ControlFrom.selector('.handle'), 
}); // Uses default setup-only recomputation
```

--------------------------------

### Inspect Active Neodrag Instances with JavaScript

Source: https://next.neodrag.dev/docs/react/plugin/introduction

Demonstrates how to inspect active Neodrag instances using the global `instances` Set. It shows how to log the total number of active instances and iterate through them to view associated elements, plugin names, and context states.

```javascript
// Check all active draggable instances
console.log('Active draggables:', instances.size);

// Inspect specific instance
for (const [element, instance] of instances) {
  console.log('Element:', element);
  console.log(
    'Plugins:',
    instance.plugins.map((p) => p.name),
  );
  console.log('Current state:', instance.ctx);
}

```

--------------------------------

### Basic Draggable Element Initialization

Source: https://next.neodrag.dev/docs/vanilla

Demonstrates the basic usage of creating a draggable instance for an HTML element. It requires importing the Draggable class and selecting the target element.

```javascript
import { Draggable } from '@neodrag/vanilla';

const dragInstance = new Draggable(document.querySelector('#drag'));
```

--------------------------------

### stateMarker Plugin Implementation (JavaScript)

Source: https://next.neodrag.dev/docs/svelte/plugin/statemarker

This snippet shows the simplified internal JavaScript implementation of the stateMarker plugin. It demonstrates how the plugin sets and updates data attributes on the root node during the setup, start, and end phases of a drag operation. It relies on a `setNodeDataset` function and context object for node manipulation.

```javascript
setup(ctx) {
  setNodeDataset(ctx.rootNode, 'neodrag', '');
  setNodeDataset(ctx.rootNode, 'neodrag-state', 'idle');
  setNodeDataset(ctx.rootNode, 'neodrag-count', '0');
},

start(ctx) {
  setNodeDataset(ctx.rootNode, 'neodrag-state', 'dragging');
},

end(ctx, state) {
  setNodeDataset(ctx.rootNode, 'neodrag-state', 'idle');
  setNodeDataset(ctx.rootNode, 'neodrag-count', ++state.count);
}
```

--------------------------------

### Neodrag Position Plugin Setup Logic

Source: https://next.neodrag.dev/docs/react/plugin/position

Illustrates the setup logic for the Neodrag position plugin. It runs when not interacting, uses `setForcedPosition()` to jump to coordinates, checks for actual changes before updating, and prioritizes running before other position-modifying plugins. It also supports live updates during active drags.

```javascript
setup(ctx) {
  if (!ctx.isInteracting) {
    const x = options?.current?.x ?? options?.default?.x ?? ctx.offset.x;
    const y = options?.current?.y ?? options?.default?.y ?? ctx.offset.y;

    if (x !== ctx.offset.x || y !== ctx.offset.y) {
      ctx.setForcedPosition(x, y);
    }
  }
}
```

--------------------------------

### Neodrag: Conditional Control Zones Based on State

Source: https://next.neodrag.dev/docs/react/plugin/controls

Implement conditional control zones in Neodrag by providing a function to `allow` or `block` properties. This function can dynamically determine which selectors to use based on application state, such as an edit mode. Recomputation can be triggered on specific hooks like 'setup' or 'start'.

```javascript
controls(
  {
    allow: (root) => {
      if (isEditMode) {
        return ControlFrom.selector('.edit-handle')(root);
      } else {
        return ControlFrom.selector('.view-handle')(root);
      }
    },
  },
  (ctx) => {
    // Recompute when mode changes
    return ctx.hook === 'setup' || ctx.hook === 'start';
  },
);
```

--------------------------------

### Neodrag Plugin Lifecycle Interface Definition

Source: https://next.neodrag.dev/docs/solid/plugin/introduction

Defines the TypeScript interface for a Neodrag plugin, outlining the available lifecycle hooks and properties. This includes `name`, `priority`, `liveUpdate`, `cancelable`, and hooks like `setup`, `shouldStart`, `start`, `drag`, `end`, and `cleanup`. The description also details the execution flow of these hooks during a drag operation.

```typescript
interface Plugin {
  name: string; // Unique identifier
  priority?: number; // Higher = runs earlier (default: 0)
  liveUpdate?: boolean; // Can update during active drag
  cancelable?: boolean; // Respects cancellation (default: true)

  setup?: (ctx) => state; // Initialize plugin
  shouldStart?: (ctx, state, event) => boolean; // Should dragging begin?
  start?: (ctx, state, event) => void; // Dragging started
  drag?: (ctx, state, event) => void; // During dragging
  end?: (ctx, state, event) => void; // Dragging ended
  cleanup?: (ctx, state) => void; // Plugin destroyed
}

/*
Execution flow:
  1. setup - Plugin initializes, returns state object
  2. shouldStart - User pressed down, should we start dragging?
  3. start - Dragging begins
  4. drag - Called repeatedly while dragging
  5. end - User released, dragging stops
  6. cleanup - Plugin destroyed (when instance is destroyed)
*/
```

### Analytics Integration with stateMarker in React

Source: https://next.neodrag.dev/docs/react/plugin/statemarker

This React example shows how to integrate drag event data with an analytics service using the stateMarker plugin. It defines a `trackDragAnalytics` function that sends drag start and end events, along with relevant data like element ID, drag count, and position, to an external `analytics.track` method.

```javascript
import { useRef } from 'react';
import { stateMarker, events, useDraggable } from '@neodrag/react';

function AnalyticsExample() {
  const ref = useRef<HTMLDivElement>(null);

  const trackDragAnalytics = (eventName: string, data: any) => {
    // Send to analytics service
    analytics.track(eventName, {
      elementId: data.rootNode.id,
      dragCount: data.rootNode.getAttribute('data-neodrag-count'),
      position: data.offset,
      timestamp: Date.now(),
    });
  };

  useDraggable(ref, [
    stateMarker(),
    events({
      onDragStart: (data) => trackDragAnalytics('drag_started', data),
      onDragEnd: (data) => trackDragAnalytics('drag_completed', data),
    }),
  ]);

  return <div ref={ref}>Analytics-tracked element</div>;
}
```
