Creating local helpers to organize Vue components for easier management

Question

Creating local helpers to organize Vue components for easier management

One of the challenges I am facing is with a Vue component that performs a series of intricate tasks within the mounted() lifecycle hook. These tasks involve setting up Bootstrap Date Pickers, Time Pickers, and Typeaheads.

Currently, all the initialization logic resides within the mounted() method, making it difficult for developers to decipher the code without reading through detailed comments.

I am considering restructuring the code by moving specific sections into their own dedicated methods and simply calling these methods within mounted(). For instance:

mounted () {
  this.helpers.initDatePickers();
  this.helpers.initTimePickers();
  this.helpers.initTypeaheads();
}

Is there a way I can achieve this? While I am aware that I could place these functions in the methods object, I would prefer to reserve that space for methods that need to be accessed from templates.

It's important to note that my focus is not on sharing helper functions across components or globally. Instead, I am seeking guidance on creating local functions within their own context to streamline longer methods.

Answer №1

If you're looking to streamline the initialization process, consider creating a mixin module that contains generic setup code.

// CustomInitMixin.js
import someLibrary from 'specific-custom-stuff';

export default {
  methods: {
    customInitialization() {
      // custom initialization logic here
    }
  }
}

Then your component can easily incorporate these mixins.

<script>
import CustomInitMixin from './mixins/CustomInitMixin';
import AdditionalLogicMixin from './mixins/AdditionalLogicMixin';

export default {
  mixins: [
    CustomInitMixin,
    AdditionalLogicMixin
  ],
  data() {/* ... */},
  // etc.
}
</script>

To avoid setting mixins repetitively, you can bundle them into a single global mixin as well.

For more flexibility in applying mixins, consider utilizing Vue's global mixin feature.

import CustomInitMixin from './mixins/CustomInitMixin';

Vue.mixin(CustomInitMixin);

Exercise caution when using global mixins, as they impact every Vue instance created, even third party components.

As mentioned by @EmileBergeron, utilizing mixins can be a beneficial solution. Additionally, creating plugins offers an expanded functionality that includes mixins and more. These plugins enable you to extend the Vue constructor or directly add instances/methods to the Vue prototype.

For more information on plugins, refer to the documentation

MyPlugin.install = function (Vue, options) {
  // 1. add global method or property
  Vue.myGlobalMethod = function () {
    // some logic ...
  }

  // 2. add a global asset
  Vue.directive('my-directive', {
    bind (el, binding, vnode, oldVnode) {
      // some logic ...
    }
    ...
  })

  // 3. inject some component options
  Vue.mixin({
    created: function () {
      // some logic ...
    }
    ...
  })

  // 4. add an instance method
  Vue.prototype.$myMethod = function (methodOptions) {
    // some logic ...
  }
}

To use your plugin:

// calls `MyPlugin.install(Vue)`
Vue.use(MyPlugin)

// pass options to your plugin
Vue.use(MyPlugin, { someOption: true })

Here's a simple example of a plugin I created that exposes various string functions from the pluralize library:

import {plural, singular, camelCase} from 'pluralize'
PluralizePlugin.install = function (Vue, options) {
    Vue.plural = plural
    Vue.singular = singular
    Vue.camelCase = camelCase
}

By using this plugin, you can easily utilize functions like this.singular(str), this.plural(str), within your components for added convenience.
