# Why Vimesh UI
I hate compiling frontend code with complex toolchains, like webpack, rollup, vite etc. Unfortunately, most frontend frameworks heavily depends on them. Alpine.js is clean, powerful and without extra build process. While it is a challenge to develop a UI library directly with Alpine.js. Vimesh UI is an ultra lightweight library to build UI components for Alpine.js.

# Basic Usages
Just add Vimesh UI CDN url before Alpine.js
```html


```
Now there are three important Alpine.js directives to build your own UI components

## x-component
This directive creates an HTML native custom element around Alpine.js template.

```html


Vimesh UI


Hello


```
[Run on codepen](https://codepen.io/vimeshjs/pen/mdKKMpb)

It shows `Hello Vimesh UI`. Now let's add some interaction logic. There are two magics `$api` and `$prop` for a Vimesh UI component. `$api` comes from the return object of the first `` inside of component template. `$prop` is function to get the passed value of component property:
```html
<head>
<script src="https://unpkg.com/@vimesh/ui">





Click me

return {
say() {
alert(this.$prop('greeting-word') + ' ' + this.$prop('who'))
}
}

```

The default custom element namespace is `vui`, which could be modified in config. You could also give a different namespace with format `x-component:{namespace}="component name"`

```html




$vui.config = {
namespace: 'myui'
}

My UI
My UI


Hello



Hi


```
[Run on codepen](https://codepen.io/vimeshjs/pen/LYrrjdq)

The final html result will be

```html
...

Hello My UI


Hi My UI

```
In some cases, we do not want the component tag to exist in the result. We could just add an `unwrap` modifier in `x-component`.

```html
...

My UI
My UI


Hello



Hi


```

The component tags `myui-greeting` and `new-greeting` will no longer exist in the final html result

```html
...

Hello My UI


Hi My UI

```

## x-import
Of course, we don't want to embed common components in every page. The `x-import` directive helps to load remote components asynchronously. Let's extract the greeting component into a standalone file.
> /hello-remote.html
```html




$vui.config.importMap = {
"*": './components/${component}.html'
}


[x-cloak] {
display: none !important;
}

Vimesh UI

```
> /components/greeting.html
```html

Cloud Hello

```
The components could be loaded from anywhere, like
```html

$vui.config.importMap = {
"*": 'https://unpkg.com/@vimesh/ui/examples/components/${component}.html'
}

```

`x-import` could load components from different namespaces. The syntax is `x-import="namespace1:comp11,comp12;namespace2:comp21,comp22;..."`. For default namespace, it could be omitted.
Here is a more complete example:
> /counters.html
```html




$vui.config.importMap = {
"*": './components/${component}.html'
}


[x-cloak] {
display: none !important;
}


Rename the 2nd counter :




```
> /components/counter.html
```html




Owner:

Step:

Value :


Increase




return {
init() {
console.log(`Value : ${this.value} , Step : ${this.step}`)
},
increase() {
this.value += this.step
}
}

```
> /components/counter-trigger.html
```html


Tigger from child element

```

## x-include
Sometimes we just need to load a piece of html. The `x-include` is convenient to use in this case. The `unwrap` modifier is used to remove the host html tag.

> /include-article.html
```html


Load into the external "div" tag:

Unwrap the external "div" tag:

```
> /static/article.html
```html

Title



Content


```

The final result will be
```html


Load into the external "div" tag:


Title



Content


Unwrap the external "div" tag:

Title



Content

## x-shtml
In Vimesh UI, please use x-shtml instead of Alpine.js original x-html, which has wrong behaviors in case of complex component lifecycle.

# Advanced Usage
## $api for component
`x-data` is very convenient to use. Its data is accessible to all descendant elements. There is no problems for simple static web page. When developping reusable components, `x-data` is too open to store component own states. We do not want the properties to be modified occasionally just because of name confliction. `$api` allows to define **private** properties and methods. `$api` is only available to current component. At the same time, it inherets from x-data. That means if `this.somePropOrMethod` does not exist in $api, it will check `somePropOrMethod` from x-data. `$api` has some predefined properties and methods:

| Properties | Description |
| ----------- | ----------- |
| $meta | Get the meta info of current component, including type, namespace, prefix. |
| $parent | Get the closest parent component element |

| Methods | Description |
| ----------- | ----------- |
| $of('component type') | Find the $api of specific component type of its ancestors. If the component type is empty, it will return the $api of its closest parent component |
| $closest(filter) | Find the closest ancestor component element according to the filter, which could be component type or a function |
| $find(filter) | Find all descendant component element according to the filter, which could be component type or a function |
| $findOne(filter) | It is similar to $find, but only return the first component element match the filter |

`x-data` has two lifecycle hooks: init and destroy. `$api` has equivalents:
| x-data | $api |
| ----------- | ----------- |
| init() | onMounted() |
| destroy() | onUnmounted() |

## $vui global variable
Once Vimesh UI is initialized, there is a global variable `$vui` attached to `window`.

| Property/Method | Description |
| ----------- | ----------- |
| $vui.config | A config object of `debug` mode flag and `importMap` |
| $vui._ | An utility object of some most used functions: `isString`, `isArray`, `isFunction`, `isPlainObject`, `each`, `map`, `filter`, `extend` |
| $vui.getComponentMeta(element) | Get component type and namespace from html element |
| $vui.isComponent(element) | Return true if an html element is a Vimesh UI component |
| $vui.visitComponents(elContainer, callback) | Recursively visit all components inside an html container element with callback |
| $vui.findChildComponents(elContainer, filter) | Find all child component inside an html container element with specific filter, which could be component type or a function |
| $vui.getParentComponent(element) | Get the parent component of specific html element |
| $vui.findClosestComponent(element, filter) | Find the closest ancestor component element according to the filter, which could be component type or a function |
| $vui.$api(element) | Get $api of a component element |
| $vui.$data(element) | Alias of Alpine.$data(element) |
| $vui.setHtml(elContainer, html) | Load html into a container element. And Vimesh UI components in the html will be correctly initialized |
| $vui.defer(callback) | Execute callback in next event loop. |
| $vui.dom(html) | Load a plain html into dom with Vimesh UI components correctly initialized |
| $vui.nextTick(callback) | Alias of Alpine.nextTick(callback) |
| $vui.effect(callback) | Alias of Alpine.effect(callback) |
| $vui.focus(element, option) | Try to make an html element focused |
| $vui.scrollIntoView(element) | Try to scroll an html element into view |

## Real UI components
[Vimesh Headless UI](https://github.com/vimeshjs/vimesh-headless) includes some useful components, like Listbox, Combobox, Menu, Dialog, Tabs, Switch etc. It is a good start point for you to develop your own UI library.
