What is the best way to import a JavaScript class into the main.js file of a Vue.js project and make it accessible in all components without needing to import it individually in each component

I have developed JS classes that I want to import into the app.js or main.js file of my vue.js project, so that I can create instances of them in various components. Currently, I find myself having to import the same JS class separately in all components where it is needed.

Although I attempted to import the class in the main.js file, the components are unable to recognize it.

In the main.js file, my import statement looks like this:

import Permissions from './Permissions'

However, when trying to instantiate the Permissions class within a component using:

data() {
permissions: new Permission({
  // some object properties...
})
}

The component does not recognize what Permissions is.

How can I make sure the component knows what the Permissions class is?

If you want to implement it with Vue, consider creating a custom plugin or mixin. You can find detailed instructions here

For example, you could create a permissions plugin in permissions-plugin.js

import Permissions from './Permissions'

const PermissionsPlugin = {
  install(Vue, options) {
    // Add the $getPermissions method to all instances
    Vue.prototype.$getPermissions = function(properties) {
      return new Permission({
        some object properties...
      })   
    }
  }
};

Then, let Vue know about your plugin:

import Vue from 'vue'
import PermissionsPlugin from './permissions-plugin.js'
import App from './App.vue'

// Load the plugin here.
Vue.use(PermissionsPlugin)

new Vue({
  el: '#app',
  render: h => h(App)
});

Now, in any component, you should be able to use your function like this:

this.$getPermissions(properties)
