Using Vue.js - How to import a custom directive as an ES6 Module

I have a very specific query.

Currently, I am utilizing Vue in my Rails application with the help of Rails Webpacker. To incorporate Vue components, I need to add a JavaScript pack tag to my layout file which references a JavaScript file responsible for rendering the Vue component. This method has required me to implement various workarounds, but there's one remaining hurdle - a custom Vue directive called click-outside. I have been adding this directive manually to all my Vue component generators, like in the case of filter-products.js

import Vue from "vue";
import filterProducts from "../../views/filter-products";
var element = document.getElementById("filter-products");
const props = JSON.parse(element.getAttribute("props"));

Vue.directive('click-outside', {
    bind: function(el, binding, vNode) {
    //bind logic
    },

    unbind: function(el, binding) {
    //unbind logic
    }
});

if (element != null) {
  new Vue({
    render: (h) => h(filterProducts, { props }),
  }).$mount(element);
}

The code for the custom directive is quite extensive. Therefore, my idea is to explore either of the following approaches:

  • Consolidate the bulk of the custom directive into an ES6 Module and simply import it here for direct usage.
  • Create a prototype for Vue that contains this custom directive and then import it instead of using vue from "vue".

Which approach do you think would be more efficient? Additionally, how can I go about implementing them? Thank you!

Answer №1

To enhance the organization and maintainability of your code, it is recommended to create a folder called directives. Within this folder, create separate files for each directive. This approach is particularly beneficial when working in a team setting:

import Vue from 'vue';

const customDirective = {
    inserted: function(el, binding) {},
    update: function(el, binding) {},
};

export default customDirective;
Vue.directive('customDirective', customDirective);//optional

Next, import the directive into any component like so:

import customDirective from 'path-to-directives-folder/directives/customDirective'

To use the directive within a component, include it as follows:

data(){
  ...
},
directives:{customDirective}
