Installation

Using NPM

npm install vue-mq

Using Yarn

yarn add vue-mq

Usage

1. Install plugin

Define your custom breakpoints by passing breakpoints option. This let you name the breakpoints as you want Eg: { phone: 500, tablet: 1200, other: Infinity } { small: 500, large: 1200, whatever: Infinity } { xs: 300, s: 500, m: 800, l: 1200, xl: Infinity }

import Vue from 'vue'
import VueMq from 'vue-mq'

Vue.use(VueMq, {
  breakpoints: { // default breakpoints - customize this
    sm: 450,
    md: 1250,
    lg: Infinity,
  }
  defaultBreakpoint: 'sm' // customize this for SSR
})

Use $mq property

After installing the plugin every instance of Vue component is given access to a reactive $mq property. Its value will be a String which is the current breakpoint.

Eg: (with default breakpoints) 'sm' => 0 > screenWidth < 450 'md' => 450 >= screenWidth < 1250 'lg' => screenWidth >= 1250

//Use it in a component
new Vue({
  template: `
    <h1>current: {{$mq}}</h1>
  `,
})

Use $mq property with the mq filter

Using the filter allow to build your responsive design in a declarative way. This can be very useful and elegant to pass down props to layout component. (eg: a grid system)

new Vue({
  template: `
    <grid-component :column="$mq | mq({ sm: 1, md: 2, lg: 3 })">
    </grid-component>
  `,
})

Remember that the filter design embrace mobile-first philosophy so writing $mq | mq({ sm: 1, lg: 3 }) will output 1 for md breakpoint if omited. In short it will always fallback to the smallest breakpoint (aka mobile) if value isn't overriden by a largest breakpoint.

Use $mq with a computed property

$mq property is fully reactive (like a data property) so feel free to use it in a computed.

new Vue({
  computed: {
    displayText() {
      return this.$mq === 'sm' ? 'I am small' : 'I am large'
    }
  },
  template: `
    <h1>{{displayText}}</h1>
  `,
})

MqLayout component

In addition to $mq property this plugin provide a wrapper component to facilitate conditional rendering with media queries.

Usage:

<mq-layout mq="lg">
  <span> Display on lg </span>
</mq-layout>
<mq-layout mq="md+">
  <span> Display on md and larger </span>
</mq-layout>
<mq-layout :mq="['sm', 'lg']">
  <span> Display on sm and lg </span>
</mq-layout>

Props mq => required : String | Array

Important: note that you can append a + modifier at the end of the string to specify that the conditional rendering happens for all greater breakpoints.

SSR Support

v1.0+ now supports SSR. You can customize the defaultBreakpoint which let you set the breakpoint used by the server-side-rendering

Browser Support

This plugin relies on matchMedia API to detect screensize change. So for older browsers and IE, you should polyfill this out: Paul Irish: matchMedia polyfill
