    Vue Browser State


    Vue Browser State is a collection of tiny browser-related implementations (around 150 bytes minified & gzipped each) for vue-reactivator.

    It features reactive properties representing:


    Tracking browser state can be tiring since you have to declare a data property, set up an event listener, hold a reference to the event handler and detach it on component destruction.

    This package contains some common browser states and makes using them as reactive properties easy.

    See this example which outputs the current size of the browser viewport:

        Your browser viewport dimensions are {{ size[0] }}x{{ size[1] }} pixels.
    import reactivator from 'vue-reactivator'
    import { viewportSize } from 'vue-browser-state'
    export default {
      mixins: [
          size: viewportSize

    See it in action

    You can take a look at the example above in CodeSandbox. Play around a little bit and resize the preview window, and you will see the numbers update immediately.


    Vue Browser State is available on npm:

    npm install vue-reactivator
    npm install vue-browser-state

    After installing, you can include as usual

    // CommonJS
    const browserState = require('vue-browser-state')
    // ES module
    import * as browserState from 'vue-browser-state'

    Want to use it in the browser directly? Try unpkg:

    <script src=""></script>
    <script src=""></script>

    Note: The implementations are stored in the vueBrowserState global variable.


    See how to use implementations with Reactivator in the example above or in the Reactivator docs.
