Vue Tables 2

npm version

This Vue package offers an easy and intuitive way of displaying Bootstrap-styled grids with data coming either from the client or from the server.

Note: Users of VueJS 1 Please use this package instead.

Note: As of version 0.5.0 the row-click event sends along an object containing the row and the mouse event.

Dependencies

  • Vue.js (>=2.0)
  • axios OR vue-resource (>=0.9.0) OR jQuery (server-side component only)

Compatibility

  • Vuex (>=2.0)
  • Bootstrap (CSS)

Installation

npm install vue-tables-2

Require the script:

import {ServerTable, ClientTable, Event} from 'vue-tables-2';

Usage

Register the component(s)

Vue.use(ClientTable, [options], [useVuex], [customTemplate]);

Or/And:

Vue.use(ServerTable, [options], [useVuex], [customTemplate]);
  • useVuex is a boolean indicating whether to use vuex for state management, or manage state on the component itself. If you set it to true you must add a name prop to your table, which will be used to to register a module on your store. Use vue-devtools to look under the hood and see the current state.
  • customTemplate argument allows you to pass a custom template for the entire table. You can find the main template file under lib/template.js, which in turn requires the partials in the template folder. The template is written using jsx, so you will need a jsx compiler to modify it (the package is using the compiled version under the compiled folder). Copy it to your project and modify to your needs.

Note: The template file is a function that receives a source parameter (client or server). E.g:

Vue.use(ClientTable, {}, false, require('./template.js')('client'))

Client Side

Add the following element to your page wherever you want it to render. Make sure to wrap it with a parent element you can latch your vue instance into.

<div id="people">
  <v-client-table :data="tableData" :columns="columns" :options="options"></v-client-table>
</div>

Create a new Vue instance (You can also nest it within other components). An example works best to illustrate the syntax:

new Vue({
    el:"#people",
    data: {
        columns: ['id','name','age'],
        tableData: [
            {id:1, name:"John",age:"20"},
            {id:2, name:"Jane",age:"24"},
            {id:3, name:"Susan",age:"16"},
            {id:4, name:"Chris",age:"55"},
            {id:5, name:"Dan",age:"40"}
        ],
        options: {
            // see the options API
        }
    }
});

You can access the filtered dataset at any given moment by fetching the filteredData computed property of the table, using ref as a pointer (this.$refs.myTable.filteredData);

Important: when loading data asynchronously add a v-if conditional to the component along with some loaded flag, so it will only compile once the data is attached.

Server side

<div id="people">
  <v-server-table url="/people" :columns="columns" :options="options"></v-server-table>
</div>

Javascript:

new Vue({
    el: "#people",
    data: {
        columns: ['id','name','age'],
        options: {
            // see the options API
        }
    }
});

All the data is passed in the following GET parameters: query,limit,page,orderBy,ascending,byColumn. You need to return a JSON object with two properties:

data array - An array of row objects with identical keys.

count number - Total count before limit.

Note: If you are calling a foreign API or simply want to use your own keys, refer to the responseAdapter option.

Implementations

I have included an Eloquent implementation for Laravel Users. If you happen to write other implementations for PHP or other languages, a pull request would be most welcome, under the following guidelines:

a. Include the class under ./server/{language}.

b. Name it according to convention: {concrete}VueTables.

c. if this is the first implementation in this language add an interface similar to the one found in the PHP folder.

d. Have it implement the interface.

e. TEST IT.

Templates

Templates allow you to wrap your cells with vue-compiled HTML. Their syntax is similar to that of render functions, as it leverages the virtual DOM to bind the templates into the main table template. It is recommended to use JSX, which closely resembles HTML, to write the templates (To compile jsx you need to install the vue jsx transform).

E.g.:

data : {
    columns: ['erase'],
    options: {
        ...
        templates: {
            erase: function(h, row) {
                return <delete id={row.id}></delete>
            }
        }
        ...
    }
}

The first parameter is the h scope used to compile the element. It MUST be called h. The second parameter gives you access to the row data. In addition a this context will be available, which refers to the root vue instance. This allows you to call your own instance methods directly. Note: when using a .vue file jsx must be imported from a dedicated .jsx file in order to compile correctly. E.g

edit.jsx

export default function(h, row) {
   return <a class='fa fa-edit' href={'#/' + row.id + '/edit'}></a>
}

app.vue

<script>
import edit from './edit'

templates: {
   edit
}
</script>

A Second option to for creating templates is to encapsulate the template within a component and pass the name. The component must have a data property, which will receive the row object. E.g:

Vue.component('delete', {
    props:['data'],
    template:`<a class='delete' @click='erase'></a>`,
    methods:{
        erase() {
            let id = this.data.id; // delete the item
        }
    }
});
options: {
    ...
    templates: {
        erase: 'delete'
    }
    ...
}

This method allows you to also use single page .vue files for displaying the template data E.g: edit.vue

<template>
    <a class="fa fa-edit" :href="edit(data.id)">Edit</a>
</template>
<script>
    export default {
        props:['data'],
    }
</script>

app.vue

<script>
import edit from './edit'

templates:{
   edit
}
</script>

If you are using Vue 2.1.0 and above, you can use scoped slots to create templates:

 <v-client-table :data="entries" :columns="['id', 'name' ,'age', 'edit']">
      <template slot="edit" scope="props">
        <div>
            <a class="fa fa-edit" :href="edit(props.row.id)"></a>
        </div>
      </template>
    </v-client-table>

Important:

  • To use components in your templates they must be declared globally using Vue.component().
  • Templates must be declared in the columns prop

Note: Don't include HTML directly in your dataset, as it will be parsed as plain text.

Child Rows

Child rows allow for a custom designed output area, namely a hidden child row underneath each row, whose content you are free to set yourself. When using the childRow option you must pass a unqiue id property for each row, which is used to track the current state. If your identifer key is not id, use the uniqueKey option to set it.

The syntax is identincal to that of templates:

options:{
  ...
  childRow: function(h, row) {
    return <div>My custom content for row {row.id}</div>
  }
  ...
}

Or you can pass a component name: (See Templates above for a complete example)

options:{
      ...
      childRow: 'row-component'
      ...
}

When the plugin detects a childRow function it appends the child rows and prepends to each row an additional toggler column with a span you can design to your liking.

Example styling (also found in style.css):

.VueTables__child-row-toggler {
  width:16px;
  height:16px;
  line-height: 16px;
  display: block;
  margin: auto;
  text-align: center;
}

.VueTables__child-row-toggler--closed::before {
   content: "+";
}

.VueTables__child-row-toggler--open::before  {
    content: "-";
}

You can also trigger the child row toggler programmtically. E.g, to toggle the row with an id of 4:

this.$refs.myTable.toggleChildRow(4); // replace myTable with your own ref

Methods

Call methods on your instance using the ref attribute.

  • setPage(page)
  • setLimit(recordsPerPage)
  • setOrder(column, isAscending)
  • setFilter(query) - query should be a string, or an object if filterByColumn is set to true.
  • refresh() Server component only

Events

Using Custom Events (For child-parent communication):

    <v-server-table :columns="columns" url="/getData" @loaded="onLoaded"></v-server-table>

Using the event bus:

Event.$on('vue-tables.loaded', function (data) {
    // Do something
});

Using Vuex:

mutations:{
  ['tableName/LOADED'] (state, data) {
    // Do something
  }
}

vue-tables.loading | tableName/LOADING (server)

Fires off when a request is sent to the server. Sends through the request data.

vue-tables.loaded | tableName/LOADED (server)

Fires off after the response data has been attached to the table. Sends through the response.

You can listen to those complementary events on a parent component and use them to add and remove a loading indicator, respectively.

vue-tables.error | tableName/ERROR (server-side)

Fires off if the server returns an invalid code. Sends through the error

vue-tables.row-click | tableName/ROW_CLICK

Fires off after a row was clicked. sends through the row and the mouse event. When using the client component, if you want to recieve the original row, so that it can be directly mutated, you must have a unique row identifier. The key defaults to id, but can be changed using the uniqueKey option.

Custom Filters

Custom filters allow you to integrate your own filters into the plugin using Vue's events system.

Client Side Filters

A. use the customFilters option to declare your filters, following this syntax:

customFilters: [
    {
        name:'alphabet',
        callback: function(row, query) {
            return row.name[0] == query;
        }
    }
]

B.

  • Using the event bus:
Event.$emit('vue-tables.filter::alphabet', query);
  • Using vuex:
this.$store.commit('myTable/SET_CUSTOM_FILTER', {filter:'alphabet', value:query})

Server Side Filters

A. use the customFilters option to declare your filters, following this syntax:

  customFilters: ['alphabet','age-range']

B. the same as in the client component.

List Filters

When filtering by column (option filterByColumn:true), the listColumns option allows for filtering columns whose values are part of a list, using a select box instead of the default free-text filter.

For example:

  options: {
    filterByColumn:true,
    listColumns:{
      animal: [
        {id:1, text:'Dog'},
        {id:2, text:'Cat'},
        {id:3, text:'Tiger'},
        {id:4, text:'Bear'}
      ]
    }
  }

The values of this column should correspond to the id's passed to the list. They will be automatically converted to their textual representation.

Custom Sorting (Client Component)

Sometimes you may one to override the default sorting logic which is applied uniformly to all columns. To do so use the customSorting option. This is an object that recieves custom logic for specific columns. E.g, to sort the name column by the last character:

customSorting:{
    name: function(ascending) {
    return function(a, b) {
        var lastA = a.name[a.name.length-1].toLowerCase();
        var lastB = b.name[b.name.length-1].toLowerCase();

         if (ascending)
            return lastA <= lastB?1:-1;

        return lastA >= lastB?1:-1;
    }
}

Options

Options are set in three layers, where the more particular overrides the more general.

  1. Pre-defined component defaults.
  2. Applicable user-defined defaults for the global Vue Instance. Passed as the second paramter to the Use statement.
  3. Options for a single table, passed through the options prop.
