The comparison between using multiple Vue.js instances and components, and implementing Ajax tabs

I am looking to incorporate ajax tabs using vue js. Each tab will need an ajax request to fetch both the template and data from an api.

Here is an example of the tabs:

<div id="tabs">
  <ul class="nav nav-tabs">
    <li class="active"><a href="#tab1" role="tab" data-toggle="tab">Tab1</a></li>
    <li><a href="#tab2" ajax-url="/tab2" role="tab" data-toggle="tab">Tab2</a></li>
    <li><a href="#tab3" ajax-url="/tab3" role="tab" data-toggle="tab">Tab3</a></li>
    <li><a href="#tab4" ajax-url="/tab4" role="tab" data-toggle="tab">Tab4</a></li>
  </ul>

  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="tab1"></div>
    <div role="tabpanel" class="tab-pane" id="tab2"></div>
    <div role="tabpanel" class="tab-pane" id="tab3"></div>
    <div role="tabpanel" class="tab-pane" id="tab4"></div>
  </div>
</div>

<script>
$('#tabs').on('shown.bs.tab', function (event) {
   var url = event.target.getAttribute("ajax-url");
   // fetch template and data..
   // init vue instance for the new tab
})
</script>

What would be the most effective way to integrate vue into this setup? Should I create separate vue instances for each tab, or use components? Additionally, I require the ability to preload some of the tabs.
Given that I need to initialize the vue instances on demand, I am uncertain about the best approach to handle this. In angular, I would define ng-controller for each tab. However, with vue.js it seems there may not be a standardized project architecture.

Answer №1

Utilize vue-router for organizing tabs.

Each tab will load a distinct View/Component when activated, leveraging the preloaded code in the vue.js bundle file.

The use of Vue Lifecycle hooks, like created and mounted, is commonplace for setting up or fetching additional data in each View.

It seems that your scenario is coherent enough to be managed by a single vue instance without the need for jQuery/AJAX.

If there are significant variations in your use-cases, it might be more efficient to construct multiple separate components, each compiled into their own JS file (typically achieved with Webpack's multiple 'entry' configuration).

UPDATE

You can bundle Vue components using the CLI; refer to: Compile .vue file into .js file without webpack or browserify

Note that each Component can mount a separate tab using the el attribute, similar to Angular's 'ng-controller' directive:

new Vue({
  el: '#tab1',
  data () {
    return {
      obj
    }
  }
})

However, attempting to control Vue instances externally from Vue (e.g., using jQuery) is generally discouraged.

If you opt for Webpack, Bootstrap can still be utilized. There are various methods to integrate Bootstrap, personally recommending importing the SCSS. Keep exploring online resources to support your progress.

If you prefer not to use the vue-router, it's recommended to utilize separate Vue instances. However, this approach may lead to memory leaks and other issues. To mitigate these issues, ensure that when making an AJAX request upon clicking a tab, you first destroy the current Vue instance before adding data to the DOM.


let app = new Vue({
    el: '#app',
})
// perform other actions
$.ajax({
    // ajax settings
    success: function(data){
        // ensure to destroy the old Vue instance here to prevent any potential issues
        app.$destroy()
        $('body').html(data);
    }
})

A more efficient solution would be to create a small JavaScript plugin. This plugin can handle AJAX requests when a link is clicked, fetch the data, and update the page while ensuring to destroy the previous Vue instance. Additionally, you can implement callbacks for loading indicators like page loaders.

In one of my projects, I implemented a jQuery AJAX-based plugin as shown below:


import $ from 'jquery';
import anime from 'animejs';

// Define Loader class
export let Loader = (function(window , document , undefined){

    // Constructor with initialization logic
    class Loader{

        constructor(options = null){
            // Configuration options
            this.options = Object.assign({ pageProgressBar : false , pageProgressBarDuraion: 2000 } , options);
            this.functions = [];
            this.xhr = null;
            this.routes = this.options.routes || [];

            window.addEventListener('load' , this.init.bind(this));
        }

        // Other methods and functionalities...

    }

    return Loader;

    // Private progress bar methods
    var $pageProgressBar = null;

    // Progress bar control functions

}(window , document , undefined));

The plugin comes equipped with progress bars and additional features which can be customized or removed according to your requirements. To implement the plugin, simply follow these steps:


window.Loader = new Loader({
    container: "#app-data",
})

Then, add the ajax-link attribute to the relevant tab links in your case. This will dynamically load content into the specified container. You can also utilize callback functions such as

Loader.beforeLoading = function(){
            app.$destroy();
        }

for added functionality.
