# vue-element-query
VueJS mixin plugin for creating element size queries in components.
_How does this library function under the hood?_
This plugin uses the [ResizeObserver API](https://wicg.github.io/ResizeObserver/) to observe element sizing changes.
As ResizeObserver is [not widely supported yet](https://caniuse.com/#feat=resizeobserver), we make use of this [ponyfill](https://www.npmjs.com/package/resize-observer-polyfill) to provide this API across non-supporting browsers.
_How is this different than the other libraries out there?_
This plugin gives each component it's own sizing queries and active breakpoint state. [Other](https://github.com/scaccogatto/vue-viewports) [libraries](https://github.com/reinerBa/Vue-Responsive) [use](https://github.com/drenglish/vue-match-media) [the](https://github.com/jofftiquez/vue-media-query-mixin) [window](https://github.com/apertureless/vue-breakpoints) [size](https://github.com/AlexandreBonaventure/vue-mq) [to determine](https://github.com/SeregPie/VueResizeSensor) [breakpoints](https://github.com/adi518/vue-breakpoint-component). This is less powerful because each component should be able to define it's own behaviour without being aware of the components around it. And that's exactly what this plugin brings to you.

# Installation
## Using NPM
```sh
npm install vue-element-query --save
```
## Using Yarn
```sh
yarn add vue-element-query
```
## VueJS
Import the plugin and register it with the current Vue instance.
```js
import Vue from "vue";
import VueElementQuery from "vue-element-query";
Vue.use(VueElementQuery);
```
This will make the mixin available for use in every component you register under this Vue instance.
# Usage
## Basic
The breakpoint queries passed in the `eq.breakpoints` option will have their active state exposed on the `$eq` object.
Any combination of the following queries can be combined to create a breakpoint:
- `minWidth`
- `maxWidth`
- `minHeight`
- `maxHeight`
A breakpoint will only be active when **all** of it's queries match.
```html
I'm a title that is always rendered.
Only visible when my component has a medium size.
Visible on either medium or large size.
I get a special class when my component is small.
export default {
eq: {
breakpoints: {
small: { maxWidth: 499 },
medium: { minWidth: 500, maxWidth: 1199 },
large: { minWidth: 1200 },
potato: { minHeight: 123, maxHeight: 1234 }
...
}
}
};
```
## Watching component size changes
A listener can be set on the breakpoint states, to watch them get (de-)activated.
This way you can trigger additional actions if needed on separate component sizes.
```js
export default {
eq: {
breakpoints: {
small: { maxWidth: 499 },
medium: { minWidth: 500, maxWidth: 1199 },
large: { minWidth: 1200 }
}
},
watch: {
"$eq.small": function(newState) {
if (newState) console.log("small breakpoint activated");
if (!newState) console.log("small breakpoint de-activated");
},
"$eq.medium": function(newState) {
if (newState) console.log("medium breakpoint activated");
if (!newState) console.log("medium breakpoint de-activated");
},
"$eq.large": function(newState) {
if (newState) console.log("large breakpoint activated");
if (!newState) console.log("large breakpoint de-activated");
}
}
};
```
## Waiting for ready state
Since [v3.1.0]((https://github.com/e2o/vue-element-query/releases/tag/v3.1.0)) of this package, an additional property `$eq.ready` has been added. This can be useful in cases where you want to render a fallback-component, without explicitly defining a breakpoint for it:
```html
```
If the medium sized breakpoint is supposed to be active, without an `$eq.ready` wrapper `` would render briefly until $eq is properly initialized, which may cause unwanted behaviour. In that case, you can wait for $eq to be properly set up:
```html
import Component1 from "@/components/Component1";
import Component2 from "@/components/Component2";
export default {
name: "App",
eq: {
breakpoints: {
medium: { minWidth: 500 },
},
},
components: {
Component1,
Component2,
},
};
```
