Collection of small, essential scripts designed to be used across various projects. These simple utilities are crafted for speed, ease of use, and versatility.

# 📚 TinyHtml Class

`TinyHtml` is a lightweight utility class that provides DOM element manipulation and querying utilities, inspired by jQuery — but built with modern native browser APIs.

It supports both static and instance-level operations, making it easy to work with elements’ dimensions, collisions, and more in a readable and performant way.

Most instance methods that do not return a specific value are designed to return the `TinyHtml` instance itself, enabling **method chaining**.
This allows you to write fluent and expressive code like:

```js
TinyHtml.createElement('div')
  .addClass('box')
  .setAttr('role', 'dialog')
  .appendTo(document.body);
```

This design keeps your code concise while maintaining clarity and control over the DOM structure.

### 💾 Internal Animation Storage

```ts
/**
 * Internal storage for animation-related data, associated with elements.
 * Used to remember original dimensions (height/width) and other properties
 * so that animations like `slideUp` and `slideDown` can restore or continue
 * smoothly, mimicking jQuery's behavior.
 *
 * Each element is mapped to a plain object with keys such as `origHeight`,
 * `origWidth`, etc.
 *
 * @type {WeakMap<HTMLElement, Record<string, string|number>>}
 */
const __elementAnimateData = new WeakMap();
```

* **Purpose:** Tracks original dimensions and properties of elements for smooth animations.
* **Type:** `WeakMap<HTMLElement, Record<string, string | number>>`
* **Notes:** Uses a `WeakMap` so that memory is automatically freed when elements are removed from the DOM.

---

### 🎬 Active Animation Tracking

```ts
/**
 * Stores the currently active animation for each element,
 * allowing cancellation or replacement of ongoing animations.
 *
 * @type {WeakMap<HTMLElement, { animation: Animation, id: string }>}
 */
const __elementCurrentAnimation = new WeakMap();
```

* **Purpose:** Keeps track of the active animation per element.
* **Type:** `WeakMap<HTMLElement, { animation: Animation, id: string }>`
* **Notes:** Useful for stopping or replacing animations mid-flight.

---

### ✨ Style Effects Definitions

```ts
/**
 * Mapping of animation shortcuts to their effect definitions.
 * Similar to jQuery's predefined effects (slideDown, fadeIn, etc.).
 *
 * @typedef {Record<string, string|(string|number)[]>} StyleEffects
 */
```

* **Purpose:** Defines reusable animation shortcuts.
* **Example:** `"fadeIn": ["opacity", 0, 1]`

---

### 🖱️ Hover Event Callback

 * @returns {void} Returns nothing.
 */
```

* **Purpose:** Defines the expected signature for hover event callbacks.
* **Parameters:** `MouseEvent ev`
* **Returns:** `void`

---

### 🏃 Active Style Animation Collection

```ts
/**
 * Represents a collection of active style-based animations.
 *
 * Each HTMLElement is associated with an array of its currently running
 * `Animation` objects (from the Web Animations API).
 *
 * @typedef {Map<HTMLElement, Animation|null>} StyleFxResult
 */
```

* **Purpose:** Tracks currently running Web Animations per element.
* **Type:** `Map<HTMLElement, Animation|null>`

---

### 📊 Animation Keyframe Data

```ts
/**
 * Represents a collection of animation keyframe data mapped by CSS property.
 *
 * - The **key** is the CSS property name (e.g. `"height"`, `"opacity"`).
 * - The **value** is an array of values representing the start and end
 *   states of the property during the animation.
 *
 * @typedef {Record<string, (string|number)[]>} AnimationSfxData
 */
```

* **Purpose:** Stores start and end states of CSS properties for animations.

 * ) => void} StyleEffectsFn
 */
```

* **Purpose:** Handles applying keyframe data to a specific CSS property on an element.
* **Parameters:**

  * `el: HTMLElement` – target element
  * `keyframes: AnimationSfxData` – property keyframes
  * `prop: string` – CSS property
  * `style: CSSStyleDeclaration` – inline style object

---

### 🛠️ Style Effect Property Handlers Collection

```ts
/**
 * A collection of style effect property handlers.
 *
 * @typedef {Record<string, StyleEffectsFn>} StyleEffectsProps
 */
```

* **Purpose:** Groups multiple property handlers for different CSS properties.
* **Type:** `Record<string, StyleEffectsFn>`

---

## 🔍 Element Debugging System

TinyHtml includes a built-in **element debugging system** to help developers identify issues with elements during validation, construction, or event handling.

This feature is **disabled by default** and can be toggled on or off.

---

### ⚙️ Enabling Debug Mode

```js
TinyHtml.elemDebug = true;  // Enable
TinyHtml.elemDebug = false; // Disable
```

#### API

* **`TinyHtml.elemDebug` (boolean)**
  Controls whether TinyHtml emits detailed debug output to the console.

* **Getter**

  ```js
  TinyHtml.elemDebug; // Returns true or false
  ```

* **Setter**

  ```js
  TinyHtml.elemDebug = true;  // Enable debug logs
  TinyHtml.elemDebug = false; // Disable debug logs
  ```

  🚨 Throws `TypeError` if the value is not a boolean.

---

### 🛠 Debugging Invalid Elements

When debug mode is enabled, TinyHtml will log structured information whenever an invalid or unexpected element is passed to its internal operations.

This is done through the internal method:

```js
TinyHtml._debugElemError(elems, elem);
```

#### Parameters

* **`elems`** → An array of elements (`ConstructorElValues | EventTarget | TinyElement | null`) involved in the operation.
* **`elem`** *(optional)* → The specific element that triggered the error.

#### Output Includes

* ❌ **Error header** in the console
* 🧭 **Stack trace** (with `console.trace` or captured stack)
* 📊 **`console.table`** showing:

  * Index
  * `typeof`
  * Constructor name
  * Summary (DOM tag, ID, class, or nodeType)
  * The raw value
* 🎯 **Problematic element** highlighted separately via `console.dir`

---

### 📋 Example Output

When debug mode is enabled and an invalid element is detected, you may see something like this:

```
[TinyHtml Debug] Element validation error
Error: [TinyHtml Debug] Element validation error
    at TinyHtml._debugElemError (...)
    at ...
```

Followed by a **console.table**:

| index | typeOf | constructor | summary            | value         |
| ----- | ------ | ----------- | ------------------ | ------------- |
| 0     | object | TinyElement | div#main.container | TinyElement{} |
| 1     | string | primitive   |                    | "invalid"     |
| 2     | null   | null        |                    | null          |

And a detailed log of the problematic element:

```
[TinyHtml Debug] Problematic element:
<div id="main" class="container">...</div>
```

---

### ✅ Summary

* 🔧 Enable debug with `TinyHtml.elemDebug = true;`
* 🐞 Detailed errors are shown only when debug mode is on
* 📊 Uses `console.table`, `console.error`, and `console.dir` for clarity
* 🚀 Zero runtime overhead when disabled

---

## 🔨 Element Creation

### `TinyHtml.createFrom(tagName, attrs?)`

Creates a new `TinyHtml` element from a given tag name and optional attributes.

* **Parameters**:

  * `tagName` *(string)* — The HTML tag name (e.g., `'div'`, `'span'`, `'button'`).
  * `attrs` *(object)* — *(optional)* Key-value pairs representing HTML attributes.

* **Returns**: `TinyHtml` — A new `TinyHtml` instance representing the created element.

* **Throws**:

  * `TypeError` — If `tagName` is not a string.
  * `TypeError` — If `attrs` is defined but not a plain object.

### 💡 Example

```js
const div = TinyHtml.createFrom('div', { class: 'container' });
const span = TinyHtml.createFrom('span', { id: 'my-span', title: null });
```

The method can also be aliased for convenience:

```js
const createElement = TinyHtml.createFrom;
const button = createElement('button', { type: 'submit', class: 'btn' });
```

---

## 🔎 Static DOM Selectors

These methods wrap native DOM query methods and return results as `TinyHtml` instances for consistency.

### `TinyHtml.createElement(tagName, ops)`

Creates a new DOM element with the given tag name and optional creation options.

* **Parameters**:

  * `tagName` *(string)* — The tag name of the element to create (e.g., `'div'`, `'span'`).

* **Throws**:

  * `TypeError` — If `tagName` is not a string.
  * `TypeError` — If `ops` is defined but not an object.

---

### `TinyHtml.createTextNode(value)`

Creates a new `TinyHtml` instance that wraps a DOM `TextNode`.

This method is useful when you want to insert raw text content into the DOM without it being interpreted as HTML. The returned instance behaves like any other `TinyHtml` element and can be appended or manipulated as needed.

* **Parameters**:

  * `value` *(string)* — The plain text content to be wrapped in a `TextNode`.

These methods convert between raw DOM and `TinyHtml` instances.

### `TinyHtml.toTinyElm(elems)`
Converts one or more raw elements or `TinyHtml` instances into `TinyHtml[]`.

```ts
TinyHtml.toTinyElm(Element | TinyHtml | Array<Element | TinyHtml>) => TinyHtml[]
```

---

### `TinyHtml.fromTinyElm(elems)`
Extracts native `Element`s from `TinyHtml` instances.

```ts
TinyHtml.fromTinyElm(Element | TinyHtml | Array<Element | TinyHtml>) => Element[]
```

---

## 🧹 Element Filtering & Matching

This section contains utilities for filtering, matching, and traversing DOM elements using selectors, functions, or references.

---

### 🎯 `TinyHtml.winnow(...)`

Advanced filtering engine used internally by many other methods.

- **Parameters**:
  - `elems`: Elements to filter.
  - `qualifier`: A selector, function, DOM element, or array of them.
  - `where`: Context string for debugging.
  - `not`: If `true`, invert the match.
- **Returns**: `Element[]`

---

### 🔍 Static Filter Utilities

#### `TinyHtml.filter(...)`
Filters elements based on a selector (with optional negation).

#### `TinyHtml.filterOnly(...)`
Same as `.filter()`, but calls `winnow()` directly without the `not` flag.

#### `TinyHtml.not(...)`
Excludes elements matching the qualifier.

#### `TinyHtml.is(...)`
Returns `true` if at least one element matches the qualifier.

#### `TinyHtml.has(...)`
Returns elements that contain a given child (selector or element).

#### `TinyHtml.closest(...)`
Finds the nearest ancestor matching a selector, optionally stopping at a context.

---

### 📦 Instance Filter Methods

#### `.not(selector)`
Returns all current elements excluding the ones that match.

#### `.is(selector)`
Checks if the current element matches the selector or qualifier.

#### `.has(target)`
Returns `true` if the current element contains the given target.

#### `.find(selector)`
Finds matching elements inside the current element.

#### `.closest(selector, context?)`
Finds the closest ancestor (including self) matching a selector or specific element.

#### `.isSameDom(elem)`
Checks if the given element is exactly the same DOM node (`===`).

---

## 💾 Element Data Store

TinyHtml supports storing arbitrary data on elements, either *publicly* or *privately*.

---

### 🔒 Internal Data System

```ts
static _dataSelector = {
  public: (where, el) => { ... },
  private: (where, el) => { ... },
};
```

* `public`: Data stored in a `WeakMap` attached to DOM nodes.
* `private`: Data stored in an internal property of the `TinyHtml` instance.

---

### 🗃️ Static Methods

#### `TinyHtml.data(el, key?, isPrivate?)`

Gets data from the element.

* **Returns**: Entire data object (if `key` omitted) or a single value.

#### `TinyHtml.setData(el, key, value, isPrivate?)`

Sets a value on the element’s data store.

#### `TinyHtml.hasData(el, key, isPrivate?)`

Checks if a specific key exists in the data store of a DOM element.

#### `TinyHtml.removeData(el, key, isPrivate?)`

Removes a value associated with a specific key from the data store of a DOM element.

---

### 📌 Instance Methods

#### `.data(key?, isPrivate?)`

Shortcut for getting data from the current instance’s element.

#### `.setData(key, value, isPrivate?)`

Shortcut for setting data on the current element.

#### `.hasData(key, isPrivate?)`

Checks if a specific key exists in the data store of this element.

#### `.removeData(key, isPrivate?)`

Removes a value associated with a specific key from the data store of this element.

---

## 🔄 DOM Traversal Methods

Navigate through the DOM tree easily: siblings, parents, children, and more.

---

### 🌱 `.parent()` / `TinyHtml.parent(...)`
Gets the **direct parent** of the element (ignores fragments).

---

### 🌳 `.parents(until?)` / `TinyHtml.parents(...)`
Collects all ancestor elements (like `.closest()`, but goes all the way up).  
Stops before `until`, if provided.

---

### ↕️ Sibling Navigation

#### `.next()` / `TinyHtml.next(...)`
Returns the next sibling (ignoring non-element nodes).

#### `.prev()` / `TinyHtml.prev(...)`
Returns the previous sibling (ignoring non-element nodes).

#### `.nextAll()` / `TinyHtml.nextAll(...)`
All siblings after the current element.

#### `.prevAll()` / `TinyHtml.prevAll(...)`
All siblings before the current element.

#### `.nextUntil(until)` / `TinyHtml.nextUntil(...)`
All next siblings **up to (not including)** a matching selector or element.

#### `.prevUntil(until)` / `TinyHtml.prevUntil(...)`
All previous siblings **up to (not including)** a matching selector or element.

---

### 🧍 `.siblings()` / `TinyHtml.siblings(...)`
All siblings of the element **excluding itself**.

---

### 👶 `.children()` / `TinyHtml.children(...)`
All child nodes (elements only) of the element.

---

### 🧩 `.contents()` / `TinyHtml.contents(...)`
Returns the contents of the element:
- For `<template>`, returns its content.
- For `<iframe>`, returns the `contentDocument`.
- Otherwise, returns its child nodes.

---

### 📋 `.clone(deep = true)` / `TinyHtml.clone(...)`
Clones the current element (or a list of elements).

- If `deep` is `true` (default), clones all children too.
- Returns an array from static, or a single node from instance.

---

### 🛠 Internal Utilities

These aren't usually called directly by users, but power most traversal:

- `TinyHtml._getSibling(el, direction)`
  - Gets the next/previous sibling that's an element.
- `TinyHtml._getSiblings(start, exclude)`
  - Returns all element siblings from a starting point (optionally excluding one).
- `TinyHtml.domDir(el, direction, until)`
  - Traverses in any direction (parent, next, previous), optionally until a selector or element.

---

* When multiple targets are passed, clones the source accordingly.

---

### 🧰 Internal Util

#### `_appendChecker(where, ...nodes)`

Normalizes and converts input (elements, arrays, or strings) into appendable DOM nodes.

> 📌 Used internally by all `append`/`prepend`/`before`/`after` methods to ensure safe insertion.

---

## 🧮 Easing Functions

### `TinyHtml.easings`

A collection of predefined easing functions used for scroll and animation calculations.
Each easing function takes a normalized time (`t` from 0 to 1) and returns a transformed progress value.

| Name             | Description                           |
| ---------------- | ------------------------------------- |
| `linear`         | Constant speed, no easing.            |
| `easeInQuad`     | Accelerates from zero velocity.       |
| `easeOutQuad`    | Decelerates to zero velocity.         |
| `easeInOutQuad`  | Accelerates, then decelerates.        |
| `easeInCubic`    | Starts slow, speeds up sharply.       |
| `easeOutCubic`   | Starts fast, slows down gradually.    |
| `easeInOutCubic` | Smooth acceleration and deceleration. |

```ts
type Easings =
  | 'linear'
  | 'easeInQuad'
  | 'easeOutQuad'
  | 'easeInOutQuad'
  | 'easeInCubic'
  | 'easeOutCubic'
  | 'easeInOutCubic';
```

```ts
TinyHtml.easings = {
  linear: (t) => t,
  easeInQuad: (t) => t * t,
  easeOutQuad: (t) => t * (2 - t),
  easeInOutQuad: (t) => (t < 0.5 ? 2 * t * t : -1 + (4 - 2 * t) * t),
  easeInCubic: (t) => t * t * t,
  easeOutCubic: (t) => --t * t * t + 1,
  easeInOutCubic: (t) => (t < 0.5 ? 4 * t * t * t : (t - 1) * (2 * t - 2) * (2 * t - 2) + 1),
};
```

## 🧭 Smooth Scrolling

### `TinyHtml.scrollToXY(el, settings)`

Smoothly scrolls one or more elements (or `window`) to a target position using a custom duration and easing.

If no `duration` or invalid `easing` is provided, the scroll happens instantly.

```ts
TinyHtml.scrollToXY(el, {
  targetX?: number,
  targetY?: number,
  duration?: number,
  easing?: Easings,
});
```

| Parameter            | Type                                             | Description                                                                                                                                        |

---

## ⚙️ Internal Scroll Mechanism

When called, `scrollToXY()` performs:

1. **Start Position Detection** – Gets current scroll positions.
2. **Delta Calculation** – Calculates the distance to scroll.
3. **Easing Evaluation** – Determines the easing curve to use.
4. **Scroll Loop** – Uses `requestAnimationFrame` to animate over time.
5. **Instant Scroll Fallback** – If no easing/duration is defined, scrolls instantly.

```ts
function executeScroll(elem, newX, newY) {
  if (elem instanceof Window) {
    window.scrollTo(newX, newY);
  } else if (elem.nodeType === 9) {
    elem.defaultView.scrollTo(newX, newY); // For documents
  } else {
    if (elem.scrollLeft !== newX) elem.scrollLeft = newX;
    if (elem.scrollTop !== newY) elem.scrollTop = newY;
  }
}
```

---

## 📏 Dimensions (Size API)

TinyHtml provides methods to **read** and **set** an element's dimensions, similar to jQuery’s width/height API, with support for box models: `content`, `padding`, `border`, and `margin`.

### 🔍 Reading Dimensions

#### `.width` / `TinyHtml.width(el)`
Returns the **content box width** (excluding padding, border, and margin).

#### `.height` / `TinyHtml.height(el)`
Returns the **content box height**.

---

#### `.innerWidth()` / `TinyHtml.innerWidth(el)`
Returns the **padding box width** (content + padding).

#### `.innerHeight()` / `TinyHtml.innerHeight(el)`
Returns the **padding box height**.

---

#### `.outerWidth(includeMargin = false)` / `TinyHtml.outerWidth(el, includeMargin)`
Returns the **border box width**, and optionally includes margin.

#### `.outerHeight(includeMargin = false)` / `TinyHtml.outerHeight(el, includeMargin)`
Returns the **border box height**, and optionally includes margin.

---

#### `.getDimension(type, extra)` / `TinyHtml.getDimension(el, type, extra)`
The underlying function used for all size getters.

```js
// Example:
element.getDimension('width', 'margin'); // Full box including margin
```

* `type`: `"width"` or `"height"`
* `extra`: `"content"`, `"padding"`, `"border"`, `"margin"`

---

### ✏️ Setting Dimensions

#### `.setWidth(value)` / `TinyHtml.setWidth(el, value)`

Sets the `width` of the element.

```js
el.setWidth(100);        // Sets width to 100px
el.setWidth("50%");      // Sets width to 50%
```

---

#### `.setHeight(value)` / `TinyHtml.setHeight(el, value)`

Sets the `height` of the element.

```js
el.setHeight("10rem");
```

---

## 📌 Position, Scroll & Box Spacing

Returns the nearest ancestor that has a position other than `static`. Useful for relative positioning logic.

---

### 🔃 Scroll Position

#### `.scrollTop()` / `TinyHtml.scrollTop(el)`
Returns the vertical scroll position of the element or window.

#### `.scrollLeft()` / `TinyHtml.scrollLeft(el)`
Returns the horizontal scroll position of the element or window.

element.setScrollTop(100); // Scrolls down 100px
window.setScrollLeft(50);  // Scrolls the window horizontally
```

---

### 📦 Box Model Sides (Padding, Margin, Border)

All methods return an object of the form:

```js
{
  x: number,     // Horizontal total (left + right)
  y: number,     // Vertical total (top + bottom)
  left: number,
  right: number,
  top: number,
  bottom: number
}
```

#### `.margin()` / `TinyHtml.margin(el)`

Returns the margin size on all four sides.

#### `.padding()` / `TinyHtml.padding(el)`

#### `.border()` / `TinyHtml.border(el)`

Returns the full border value (`borderLeft`, `borderTop`, etc.) on all sides. Rarely needed unless you’re working with composite CSS values.

---

## 🎨 Class Manipulation

## 🎛️ Form Value Handling & Input Hooks

This section handles reading and writing values for form controls (`input`, `select`, `option`, `checkbox`, `radio`, etc.) with support for custom hooks to manage special cases seamlessly.

---

### 🪝 `_valHooks`

Internal value hooks for form controls

- **option**: Gets the option value or fallback to text.
- **select**: Handles single/multiple select value getting/setting.
