vue-ripper

This set of 4 components allow a parent component to divide some of its children component to display different parts at different places.

An example is to give a table-definition column-wise:

<mytable>
    <mycolumn letter="a">
    <mycolumn letter="b">
    <mycolumn letter="c">
</mytable>

In html, the table will be defined row-wise:

<table>
    <tr>
        <th>a</th>
        <th>b</th>
        <th>c</th>
    <tr>
    <tr>
        <td>
            ...

In order to do that, we have to separate the table-header and the table-cell definition, to display them at different places.

Installation

npm install --save vue-ripper
import {Ripper, Pimp, Ripped, Depot} from 'vue-ripper'
- or -
import ripper from 'vue-ripper'
Vue.install(ripper);

The ripping set

These 3 components (Ripper, Pimp, Ripped) often work together. The rippers (often provided by your component' users) are gathered by the pimps that provide the ripped parts.

Ripper

The ripper allows to define the component that will be dislocated in pieces. In our exemlpe, this is the template of the column.

<template>
    <ripper>
        <template slot="header" class="table-header">
            {{letter.toUpperCase()}}
        </template>
        <template slot-scope="scope" class="table-cell">
            {{letter.toLowerCase() + scope.number}}
        </template>
    </ripper>
</template>

The ripper allows to define templates and will render nothing (indeed, a comment element). The ripper should of course be the top-element of the (here mycolumn) component.

Pimp

The pimp is used in the parent component to gather all the rippers.

A pimp will basically render a <div style="display: none;" />, although a tag can be specified with the is keyword : <thead is="pimp" ...>. As it is supposed to contain rippers, it will contain only comment elements.

Its role is to keep its v-model updated with the list of VueComponent it directly contains. For configurable components, that is in the pimp that the <slot /> is placed.

Note: the list is given as an array of component. For the key, use component._uid

Regular usage:

<pimp v-model="columns">
    <slot />
</pimp>

Ripped

The ripped is where a piece of the ripper is placed. It specifies the slot name and scope if given.

For example, to render the header of a column :

<th is="ripped" v-for="(column, uid) in columns" :key="uid"
    template="header"
    :ripper="column"
>
    A field
</th>

For example, to render the cells of a given row:

<td is="ripped"
    v-for="(column, uid) in columns" :key="uid"
    :ripper="column"
    :scope="{row}" />

If a custom render function is provided, this function is called with the createNode function and the slot (vNode[]) as arguments. If no tag is given (by using <ripped ...>), then the template must contain exactly one element and it won't be wrapped. If a tag is given (by using <span is="ripped" ...>), it will wrap the template.

  • template: Name of the slot taken from the ripper, defaults to default
  • scope: If given, the template will be a scoped slot.
  • ripper: The VueComponent to rip appart.
  • render: (h: createNode, slot: vNode[]) => vNode[] to render programatically the ripped. If the ripper doesn't give the slot, the ripped's content will be used instead.

Depot

The depot is a stand-alone component that can be used to re-order slots and wrap their rendering programmatically. A depot will basically render in a <div>, although a tag can be specified with the is keyword : <thead is="depot" ...>.

It can be given a slot order as an array of string slot-names. Some how, <depot :order="['a','c','b']"> corresponds to a component with this template :

<div>
    <slot name="a" />
    <slot name="c" />
    <slot name="b" />
</div>

The slots that are not specified in the order won't be rendered. If the depot is given no order, it will only render the default slot. (this can be useful to just map it)

The depot can also be given a map: (slot: vNode[], name: string, h: createElement)=> vNode[]. If a map function is given, it will be called for each rendered slots. The function could return slot to have no effect.

  • slot is the list of elements given in the slot
  • name is the slot' name
  • h is the render-function provided by Vue to create vNodes.

If the function returns nothing, the slots will be used. In order to render nothing, [] has to be returned.
