# is-http2

Simple module to check if certain servers out there support HTTP/2.

## install

```

$ npm install --save is-http2

```

## Pre-requisites

To make `is-http2` work, you need to have [openssl](http://openssl.org/) in a version greater than 1.0.0 installed and available in your `$path`.

## Basic usage

### isHttp2( url, options )

**Description** : Check if server behind given url supports HTTP/2

**url** : Url to check HTTP/2 support for

#### Options 

* **includeSpdy** : optional: should SPDY be considered HTTP/2

* **openssl** : optional: specify custom openssl command (i.e. '/usr/local/Cellar/openssl/1.0.2k/bin/openssl') 

`isHttp2` returns a Promise which will be resolved with an Object containing `isHttp2` and `supportedProtocols`.

```javascript

const isHttp2 = require( 'is-http2' );

isHttp2( 'twitter.com', { includeSpdy : true } )

  .then( function( result ) {

    if ( result.isHttp2 ) {

      console.log( `${ chalk.green( '✓' ) } HTTP/2 supported by ${ host }` );

    } else {

      console.log( `${ chalk.red( '×' ) } HTTP/2 not supported by ${ host }` );

    }

    if ( result.supportedProtocols ) {

      console.log(

        `Supported protocols: ${ result.supportedProtocols.join( ' ' ) }`

      );

    }

  } )

  .catch( function( error ) {

    console.error( chalk.red( error ) );

    process.exit( 1 );

  } );

```
