# v-tail-vue3
A component library for Vue 3 using UnoCSS.
## Installation

Install the library via `npm install --save @s3_dse/v-tail-vue3`.

In your `uno.config.js` import and install the preset:

```js
import { defineConfig, presetUno } from 'unocss'
import presetVTail '@s3_dse/v-tail-vue3/preset'

export default defineConfig({
    presets: [presetUno(), presetVTail()]
})

```

Add the following to your entry point (e.g. `main.js`):
```js
import VTail from '@s3_dse/v-tail-vue3'

import { createApp } from 'vue'
import App from './App.vue'
const app = createApp(App)
app.use(VTail)

app.mount('#app')
```
# Components
## Table Component
A table that supports
* filtering
* pagination
* custom column and cell rendering
* fixed top row(s) (e.g. for comparisons)
* fixed bottom row(s) (e.g. for summaries)

## Usage
We will use the following lines to illustrate the usage of the table component:
```html
<template>
    <table-component
        title="A Table"
        :items="data"
        :top-rows="topRows"
        :bottom-rows="summaryRows"
        :fields="header"
        :paginate="true"
        :configurablePageSize="true"
        :per-page="5"
        @after-sort="afterSort"
        @after-page-change="afterPageChange"
        @after-filter="afterFilter"
        :pagination-previous-label="'<'"
        :pagination-next-label="'>'"
    >
        <template #cell(ip_address)="{ value }">
            <p class="tw-text-primary">{{ value }}</p>
        </template>
        <template #pagination-label="{ perPage, currentPage, totalEntries }">
            I am currently showing entries 
            {{ perPage * currentPage - perPage + 1 }} to
            {{ perPage * currentPage }} of {{ totalEntries }} entries.
        </template>
        <template #page-size-label="data">
            Current Page Size: {{ data.pageSize }}
        </template>
    </table-component>
</template>
<script>
export default {
    name: 'App',
    data() {
        return {
            data: [
                { id: 1, name: 'John Doe', share: 0.51, ip_address: '111.222.47.186', last_login: '2023-01-31' },
                { id: 2, name: 'Jane Doe', share: 0.08, ip_address: '71.190.227.13', last_login: '2023-04-10' }
            ],
            topRows: [

            ],
            bottomRows: [
                {id: 5, name: 'Jordan Winsley', share: 0.81, ip_address: '141.147.221.67', last_login: '2023-04-28'}
            ],
            fields: [
                { key: 'id' }, 
                { key: 'name' },
                { key: 'share',
                  thClassList: 'tw-text-right tw-px-2',
                  tdClassList: 'tw-text-right tw-px-2',
                  tdTopRowClassList: 'tw-text-right tw-px-2 tw-italic',
                  tdBottomRowClassList: 'tw-text-right tw-px-2 tw-font-semibold',
                  formatter: value =>
                          value
                              ? (parseFloat(value) * 100).toLocaleString(navigator.language, {
                                  minimumFractionDigits: 0,
                                  maximumFractionDigits: 2
                              }) + '%'
                              : ''
                }
                { key: 'ip_address',
                  thClassList: 'tw-text-center tw-px-2',
                  tdClassList: 'tw-text-center tw-px-2',
                  tdTopRowClassList: 'tw-text-center tw-px-2 tw-italic',
                  tdBottomRowClassList: 'tw-text-right tw-px-2 tw-font-semibold'
                }
            ]
        }
    }
}
</script>
<style>
@import '@s3_dse/v-tail-vue3/style.css';
</style>
```

We pass the table data as an array of objects via the `:items` attribute. The same applies to the optional `:top-rows` and `:bottom-rows`. The entries of all three data arrays need to have the same structure. The `:fields` attribute takes an array of objects with details regarding the rendering of particular fields. Field entries have a `key` to refer to a data entry's property. The remaining field properties are metadata to customize the rendering of the column:
 * `thClassList`: classes for styling the column's `<th>` content (only applied to `:items` records)
 * `tdClassList`: classes for styling the column's `<td>` content (only applied to `:items` records)
 * `tdTopRowClassList`: classes for styling the column's `<td>` content (only applied to `:top-rows` records)
 * `tdBottomRowClassList`: classes for styling the column's `<td>` content (only applied to `:bottom-rows` records)
 * `formatter`: a function defining a formatting logic for the values of that field/column
 * `type`: Either `numeric` or `alphanumeric`, explicitly influences sort behaviour

Only those attributes present in the field array will be displayed in the resulting table.

### Pagination
The page navigation can be enabled/disabled via the `:paginate` attribute. This will toggle pagination in general. The page size configurator can be enabled/disabled via the `:configurable-page-size` attribute. Both these attributes take boolean values and are `true` by default. They are part of the above example only for illustration.

If the pagination is done outside of the component, e.g. server side pagination, you can provide `:remote-pagination="true"` and the number of total records via `:totalItems`. 

### Cell Rendering
The above example shows how to use the `#cell()` slot to customize the rendering of individual cells. The slot is dynamic and takes a field key as argument. It provides an object holding the actual cell `value`, the `item` (or record) of the `:items` array, and the `field` of the `:fields` array.

| topRows     | Sticky records at the top. |
| bottomRows     | Sticky records at the bottom. |
| perPage     | The number of records displayed per page. Default is `5`. |
| configurablePageSize     | When `true` a dropdown control allows to select between page sizes. |
| pageSizes     | Array of page sizes to chose from. Default is `[5, 10, 25, 50]` |
| pageSizeButtonClassList    | Configure styling of page size button. String. |
| searchInputClassList    | Configure styling of search input. String. |
| paginate    | Whether pagination is enabled or not. |

| filterMaxWait    | Max wait time in ms for the search (filter) input. Default is `2000`.|
| sortNullsFirst    | When `true` will sort `null\|undefined` first, when `false` will sort them last.

### Events
| Event | Description |
|-------|-------------|
| per-page-change | Emits the number of displayed items per page when it has changed. |
| page-change | Emits the current page number when it has changed.  |
| sort-change | Emits an object with sorting information, when data is sorted by a column. Example: `{ sortColumn: { key: 'column_a' }, ascending: false }` |
| filter-change | Emits the current search term when it has changed.  |
| filter-change-debounced | Emits the current search term when it was changed and a debounce interval was reached. Can help to avoid request spamming. |


### Credits
The component is heavily inspired by the Bootstrap Vue Table component. Have a look: https://github.com/bootstrap-vue/bootstrap-vue

## Dialog Component (Radix Vue)

A component for displaying modal dialogs. 
### Usage

```html
<script setup>
...
const validateAndSubmit = () => {
    const selection = document.querySelector('.custom-select').selectedOptions[0].innerText
    if (selection === 'a') {
        console.log('Error: Option "a" is not allowed!')
        return false
    } else {
        console.log('success')
        submitLogic()
        return true

    }

}
</script>
<template>
    ...
    <dialog-component title="Testing Dialog" description="A dialog..." @cancel="test" :pre-confirm="validateAndSubmit">
