$ npm install --save opn

var opn = require('opn');

opn('https://sindresorhus.com');
// opens that url in the default browser

opn('https://sindresorhus.com', 'firefox');
// you can also specify the app to open in

opn('https://sindresorhus.com', ['google-chrome', '--incognito']);
// you can also specify the arguments of app

opn('unicorn.png');
// opens the image in the default image viewer

Uses the command open on OS X, start on Windows and xdg-open on other platforms.

Required Type: string

The thing you want to open. Can be a url, file, or executable.

Opens in the default app for the file type. Eg. urls opens in your default browser.

Type: string, array

Specify the app to open the target with. Where if is array, first will be app name, other will be app arguments

The app name is platform dependent. Don't hard code it in reusable modules.

On Windows you have to explicitly specify an app for it to be able to wait.

You can also use it as a CLI app by installing it globally:

$ npm install --global opn

$ opn --help

  $ opn <file|url> [app] [app arguments]

Example
  $ opn https://sindresorhus.com
  $ opn https://sindresorhus.com firefox
  $ opn https://sindresorhus.com google-chrome --incognito
  $ opn unicorn.png
