Component without template

问题

I have a bit of code that makes an api call to a server and returns some JSON.

It did exist as a method in my component but as it is getting a bit long I want to extract it to it's own file

In vuejs what is the best practice here.

should it be a component without a template? How would this work?
will I just create an es6 module?

I would suggest using a mixin here.

In a file like myCoolMixin.js define your mixin...

export default {
   methods: {
      myAwesomMethod() {
         //do something cool...
      }
   }
}

You can define anything in a mixin just like a component. e.g. data object, computed or watched properties, etc. Then you simply include the mixin in your component.

import myCoolMixin from '../path/to/myCoolMixin.js'

export default {
   mixins: [myCoolMixin],
   data: function() {
      return: {
         //... 
      }
    },
    mounted: function() {
       this.myAwesomeMethod(); // Use your method like this!  
    }
 }

Mixins work, or you could create a plugin. Here's the docs example:

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

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

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

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