Embracing the power of mixins in Vue.js

Currently in the process of learning app development with Vuejs. In my main.js file, I have the code for setting up Vue.js. Recently, I created a new directory called /mixins and added a file named api.js. My intention is to use this as a mixin so that every component can access a function to interact with my API. However, I am unsure about how to proceed.

This is the content of my /mixins/api.js file:

export default{
  callapi() {
    alert('code to call an api');
  },
};

The contents of my main.js file are as follows:

import Vue from 'vue';
import VueRouter from 'vue-router';
import VueResource from 'vue-resource';

import { configRouter } from './routeconfig';

import CallAPI from './mixins/api.js';

// Registering to vue
Vue.use(VueResource);
Vue.use(VueRouter);

// Creating Router
const router = new VueRouter({
  history: true,
  saveScrollPosition: true,
});

// Configuring Router
configRouter(router);

// Running the App
const App = Vue.extend(
  require('./components/app.vue')
);

router.start(App, '#app');

What would be the correct way to include my mixin now, ensuring that every component has access to the callapi() function?

Answer №1

To apply a mixin to a specific component instead of all components, you can follow this approach:

mixin.js

export default {
  methods: {
    myMethod() { .. }
  }
}

component.vue

import mixin from 'mixin';

export default {
  mixins: [ mixin ]
}

Another technique to consider is the use of a component extension design pattern, where you create a base component and then extend it in subcomponents. This is more intricate but helps maintain DRY code when multiple components share similar options and potentially inherit the template as well.

If you're interested, I have written about this topic on my blog.

Answer №2

To globally apply mixins in Vue, you can use Vue.mixin

api.js
------

export default {
  methods: {
    callapi() {};
  }
}

main.js
-------

import CallAPI from './mixins/api.js';

Vue.mixin(CallAPI)

The official documentation advises caution when using global mixins:

Proceed with caution when using global mixins as they impact every Vue instance created, including third-party components.
