Mixins are a flexible way to distribute reusable functionalities for Vue components. A mixin object can contain any component options. When a component uses a mixin, all options in the mixin will be “mixed” into the component’s own options.
// define a mixin object
var myMixin = {
created: function () {
this.hello()
},
methods: {
hello: function () {
console.log('hello from mixin!')
}
}
}
// define a component that uses this mixin
var Component = Vue.extend({
mixins: [myMixin]
})
var component = new Component() // -> "hello from mixin!"
