@AndBoh/vue-screen

Reactive wrapper for window size and scroll position for Vue 2.

Motivation

Sometimes you need to watch the size of the window inside the javascript application code, but the window object is not reactive. This plugin for Vue 2 provides a reactive object with current window size, scroll position and touch feature.

Installation

1. Install plugin

npm i -S @andboh/vue-screen

#2. Use in your app

    import VueScreen from '@andboh/vue-screen';

    Vue.use(VueScreen, { options });

Plugin options fields

number debounce - Debounce time in ms to avoid recalculating values too often. Defaults to 150.

number defaultWidth, number defaultHeight - Standard window size if the window object is undefined (for example, with SSR). Defaults to 1920 and 1080.

Usage

You can get value in any component accessing this.$screen option

    console.log(this.$screen);

Result:

    {
          window: {
               height: 969, // window client height
               width: 1920, // window client width
          },
          scroll: {
              x: 0, // scroll x position
              y: 0, // scroll y position
          },
          hasTouch: false // is it touch device
    }

Also, you can set a deep watcher for the whole object

    watch: {
        $store: {
            handler(newVal) {
                ...
            },
            deep: true,
        }
    }

or any field of it

    watch: {
        '$store.window.width'(newVal) {
            ...
        }
    }
