ngTableAsync

ngTable wrapper that offers some base functionality and abstractions for working with asynchronous tables. It serves as a way to avoid table boilerplate code, by declaring only those things relevant in our context.

It's specially useful for backoffice/dashboard developers, so they can come out with a fully functional asynchronous table with a default Bootstrap style in very few quick steps, where behaviour has more priority than markup.

This module in no way intends to be a replacement for ngTable, but an enhancement. If it doesn't satisfy your needs, submit a feature PR or go back to ngTable :).

Requirements

• AngularJS
• Bootstrap - styles only
• Lodash
• ngTable

Optional requirements

• UI.Bootstrap

Installation

1. Include dependency files in your markup:

• <link rel="stylesheet" href="bootstrap.css">
• <script src="lodash.js"></script>
• <script src="angular.js"></script>
• <script src="ui-boostrap.js"></script>
• <script src="ng-table.js"></script>

2. Include ngTableAsync files in your markup:

• <link rel="stylesheet" href="ng-table-async.css"></script>
• <script src="ng-table-async.js"></script>

3. Include ngTableAsync as a module dependency in your AngularJS app:
   angular.module('myApp', [ ... 'ngTableAsync' ... ])

NOTE: ng-table-async.js contains the raw ngTableAsync module, whereas ng-table-async-tpls.js also includes default directives' templates. If you choose the first, you must supply all templates yourself, just the same as if you choose ui-bootstrap.js over ui-boostrap-tpls.js.

Usage

ngTableAsync offers a way to write HTML tables in a column-oriented declarative way:

<ng-table-async options="tableOptions">
  <nta-column header="'id'" content="item.id"></nta-column>
  <nta-column header="'Email'" content="item.email"></nta-column>
  <nta-column header="'Counter'">
    <span ng-bind="item.counter"></span>
    <nta-action action="increment" size= "xs" icon="glyphicon glyphicon-plus"></nta-action>
  </nta-column>
  <nta-column>
    <nta-header>Actions</nta-header>
    <nta-content>
      <nta-action label="Reset counter" action="reset" size="xs" icon="glyphicon glyphicon-ban-circle"></nta-action>
      <nta-action label="Remove" action="remove" size="xs" icon="glyphicon glyphicon-trash" style="danger"></nta-action>
    </nta-content>
  </nta-column>
</ng-table-async>

• nta-column: defines a column.
  • Children
    • nta-header: defines HTML markup for column header
    • nta-content: defines HTML markup for column content.

By looking at the above example, we can infer that:

• Both children of nta-column can also be defined as header and content attributes of the nta-column element, respectively.
• Child-wise definition takes more precedence than attribute-wise definition.
• If the only child of nta-column is nta-content, then we can skip the nta-content tag.
• There is a nta-action element that seems to define an action.

Directives

ngTableAsync also defines the following directives for further customization:

Directive: ntaAction

To declare action buttons for each row element in the table. It is only allowed as child of nta-header or nta-content elements. Supports the following attributes configuration:

• label: Action button label
• action: Key referencing an action in the actions array of ngTableAsync. See Configuration object section for more information.
• size: Action button size, using Bootstrap size suffixes. Suppported values: xs, sm, lg. Defaults to default button size.
• icon: Action Button icon class. Defaults to no icon.
• style: Action button style, using Bootstrap style suffixes. Supported values: default, primary, success, info, warning, danger, link. Defaults to default.
• template-url: Markup template url. Defaults to '_ng_table_async_action.html'

  When overriding this template, ngTableAsync exposes all this attributes in the scope, plus a function do. You may or may not make use of them but you should not forget to call the do function to trigger the action in the template. For example: include ng-click="do()" in some button in your custom template.

<ng-table-async>
  ...
  <nta-action
    label="Delete me!"
    action="delete"
    size="xs"
    icon="glyphicon glyphicon-trash"
    style="danger"
    template-url="my_custom_action.html"></nta-action>
  ...
</ng-table-async>

Directive: ntaLoading

To render the 'Loading table' markup. Supports the following attributes configuration:

• template-url: Markup template url. Defaults to '_ng_table_async_loading.html'

<ng-table-async>
  ...
  <nta-loading template-url="my_custom_loading.html"></nta-loading>
  ...
</ng-table-async>

NOTE: ntaLoading directive is only used to override 'Loading table' page template. Neither its location nor the times it is included in the markup have any kind of influence in the resulting table.

Directive: ntaNoData

To render the markup to show when table is empty. Supports the following attribute configuration:

• text: Text to show when table is empty.
• template-url: Markup template url. Defaults to '_ng_table_async_no_data.html'

  When overriding this template, ngTableAsync exposes the text attribute in the scope of the template. You may or may not make use of it.

<ng-table-async>
  ...
  <nta-no-data text="Table is empty!!" template-url="my_custom_no_data.html"></nta-no-data>
  ...
</ng-table-async>

NOTE: ntaNoData directive is only used to override 'No results available' page template. Neither its location nor the times it is included in the markup have any kind of influence in the resulting table.

Directive: ntaPager

To render the pagination markup template. Supports the following attribute configuration:

• template-url: Markup template url. Defaults to '_ng_table_async_pager.html'

  When overriding this template, please refer to ngTable's documentation on how to override its pager.

<ng-table-async>
  ...
  <nta-pager template-url="my_custom_pager.html"></nta-pager>
  ...
</ng-table-async>

NOTE: ntaPager directive is only used to override pager's template. Neither its location nor the times it is included in the markup have any kind of influence in the resulting table.

Configuration object

ngTableAsync accepts an options attribute for initialization of table-level settings:

<ng-table-async options="tableOptions">
  ...
</ng-table-async>

Of course, tableOptions should be exposed in the scope where ngTableAsync is being created, and it can contain any of the following properties:

$scope.tableOptions = {
  defaultPage   : 3,     // Default selected page.                        Defaults to 1.
  pageSize      : 5,     // Table page size.                              Defaults to 10.
  pagerOnTop    : true,  // Enable pager above table.                     Defaults to false.
  pagerOnBottom : false, // Enable pager below table.                     Defaults to true.
  headerIfEmpty : false, // Do not hide table header when table is empty. Defaults to true.

  // REQUIRED
  // Function to retrieve current page's data, in terms of 'skip' and 'limit' params
  // skip: rows to skip from the beggining of the data.
  // limit: quantity of rows to return.
  // Returns a promise of an array of data.
  getPage: function(skip, limit){
    returns API.items.getPage(skip, limit);
  },

  // Actions
  // Each action can be a Function or an Object.
  actions: {

    // Action definition using Object form
    actionName: {
      reload: false,  // Reload table on this action's completion. Defaults to true.
      method: function(item){
        // Action to perform on row item.
        // If a promise is not returned, it will be promisified internally.
        // ngTableAsync will render the 'Loading table' markup until action completion.
      },

      // If action requires confirmation dialog.
      // Action method will only be triggered on dialog acceptance.
      // IMPORTANT: UI.Bootstrap should be included for dialog to work.
      dialog: {
          templateUrl : '_my_action_dialog.html',
          params      : {}                         // Params to be passed to dialog template scope.
          onCancel    : function(item, params){}   // To be called on dialog cancel
      }
    },

    // Action definition using Function form.
    // Simplest form to define an action.
    // Table will be reload on completion, and no dialog confirmation is required.
    // Same as: anotherActionName: { method: function(item){} }
    anotherActionName: function(item){},
  }
};
