# modernizr-esm

[![Build Status][ci-img]][ci] [![BrowserStack Status][browserstack-img]][browserstack]

[Modernizr](http://modernizr.com) tests as ES Modules.

Features:

* Each test can be imported and used separately

* Tests return multiple named exports if they test multiple features

* Async tests support Promises as result

* No global modifications like setting classes on `html` element

* Ignores browser globals when imported directly in SSR environment

**[Try it now!](https://codesandbox.io/s/demo-i942i?expanddevtools=1&fontsize=14)**

Refer to [original Modernizr documentation](https://github.com/Modernizr/Modernizr/blob/master/README.md) for more information.

## Install

```sh

npm install modernizr-esm --save

```

## Usage

```js

import emoji from 'modernizr-esm/feature/emoji';

console.log(emoji); // Are emojis supported?

```

### Async tests

```js

import flash from 'modernizr-esm/feature/flash';

flash(( support ) => {

	console.log(support); // Is Flash supported?

});

```

If you don’t provide callback, calling function will return Promise.

```js

import flash from 'modernizr-esm/feature/flash';

flash().then(( support ) => {

	console.log(support); // Is Flash supported?

});

```

### Multiple feature tests

```js

import { cssgrid } from 'modernizr-esm/feature/css/cssgrid';

console.log(cssgrid); // Is CSS Grid supported?

```

### Setting feature HTML classes

Use `classList` and export value of feature test:

```js

import emoji from 'modernizr-esm/feature/emoji';

document.documentElement.classList.add(`${emoji ? '' : 'no-'}emoji`);

```

Or if you want to use Modernizr HTML class setter:

```js

import setClasses from 'modernizr-esm/src/setClasses';

import emoji from 'modernizr-esm/feature/emoji';

setClasses([`${emoji ? '' : 'no-'}emoji`]);

```
