What - tiny plugin for working with responsiveness intervals, focused runtime performance and great DX.
Why - I'm obsessed with runtime performance and ease of use: see how it works.

Installation

yarn

yarn add vue-responsiveness

npm

npm i vue-responsiveness

Basic demo

Codesandbox

Usage

main.ts

import { VueResponsiveness } from 'vue-responsiveness'

createApp()
   .use(VueResponsiveness)
   .mount('#app')

in any `<template />`:

<!-- @media (min-width: 576px) -->
<template v-if="$matches.sm.min">
     ...content
</template>

<!-- @media (max-width: 767.9px) -->
<SomeComponent v-if="$matches.sm.max">
  ...content
</SomeComponent>

<!-- @media (min-width: 576px) and (max-width: 767.9px) -->
<div v-if="$matches.sm.only">
  ...content
</div>

Breakpoint presets:

import { VueResponsiveness, Presets } from "vue-responsiveness";

app.use(VueResponsiveness, Presets.Tailwind_CSS)

Note: The default config value is set to Bootstrap 5's responsiveness breakpoints preset.

Presets.Bootstrap_5 = {
  xs: 0,
  sm: 576,
  md: 768,
  lg: 992,
  xl: 1200,
  xxl: 1400,
}

Available presets:

Bootstrap_3, Bootstrap_4, Bootstrap_5, Bulma, Chakra, Foundation, Ionic, Master_CSS, Material_Design, Materialize, Material_UI, Quasar, Semantic_UI, Skeleton, Tailwind_CSS, Vuetify, Windi_CSS

Notes:

If you maintain a CSS framework (or use one often) and want its preset added, open an issue or a PR.
If you spot any inconsistency in the presets (either my typo or some library update), please, let me know, I'll correct it.

Bespoke intervals:

app.use(VueResponsiveness, {
  small: 0,
  medium: 777,
  large: 1234
})

<!-- @media (min-width: 777px) and (max-width: 1233.9px) -->
<template v-if="$matches.medium.only">
  ...content
</template>

Hide components, (while still rendering them) - usage with `v-show`:

<SomeComponent /> below will be rendered at all times but will only be displayed on md and below:

<!-- rendered at all times (keeps listeners while hidden), but only displayed on 
  @media (max-width: 991.9px) -->
<SomeComponent v-show="$matches.md.max" />

Use in `setup()` or `<script setup>`:

import { useMatches } from 'vue-responsiveness'

const matches = useMatches()

const currentInterval = computed(() => matches.interval)
const trueOnSmOnly = computed(() => matches.isOnly('sm'))
const trueOnMdAndAbove = computed(() => matches.isMin('md'))

Testing:

Add plugin to global.plugins when testing components using the plugin's API: Example

import MyComponent from './MyComponent.vue'
import { VueResponsiveness } from 'vue-responsiveness'
describe('<MyComponent />', () => {
  it('should render', () => {
    const wrapper = shallowMount(MyComponent, {
      global: {
        plugins: [VueResponsiveness]
      }
    })
    // test here    
  })
})

How it works:

uses the native window.matchMedia(queryString) and only reacts to changes in the query's matches value. It's the same API powering CSS media queries.
listeners are placed on the MediaQueryList instances, meaning they are garbage collected as soon as the app is unmounted, without leaving bound events behind on <body> or window object.
no global pollution
only one instance per app (much lighter than having one instance per component needing it)
in terms of memory and/or CPU consumption, using window.matchMadia is a few hundred times lighter than using the "traditional" resize event listener method

Got issues?

Let me know!

Happy coding!
