You can launch browsers! With NodeJS!
- Local browsers for MacOS, Windows and Linux (like) operating systems
- BrowserStack browsers using the BrowserStack API
- Remote browsers using the launchpad server
The general API for any launcher (<type>
) looks like this:
var launch = require('launchpad');
launch.<type>(configuration, function(error, launcher) {
launcher.browsers // -> List of available browsers
launcher(url, configuration, function(error, instance) {
instance // -> A browser instance
instance.id // -> unique instance id
instance.stop(callback) // -> Stop the instance
instance.status(callback) // -> Get status information about the instance
});
});
Local launchers look up all currently installed browsers and allow you to start new browser processes.
// Launch a local browser
launch.local(function(err, local) {
local.browsers // -> List of all browsers found locally
local.firefox('http://url', function(err, instance) {
// An instance is an event emitter
instance.on('stop', function() {
console.log('Terminated local firefox');
});
});
});
BrowserStack is a great cross-browser testing tool and offers API access to any account that is on a monthly plan. Launchpad allows you to start BrowserStack workers through its API like this:
launch.browserstack({
username : 'user',
password : 'password'
},
function(err, browserstack) {
browserstack.browsers // -> List of all browsers
browserstack.ie('http://url', function(err, instance) {
// Shut the instance down after 5 seconds
setTimeout(function() {
instance.stop();
}, 5000);
});
});
Behind the scenes we have the node-browserstack module do all the work (API calls) for us.
Launchpad also allows you to start browsers on other systems that are running the Launchpad server.
The launchpad server is a simple implementation of the BrowserStack API (Version 1) which provides a RESTful interface to start and stop browsers. You can set up a Launchpad server like this:
launch.server({
username : 'launcher',
password : 'testing'
}).listen(8080, function () {
console.log('Listeining...');
});
Because the Launchpad server is compatible with the BrowserStack API (Version 1), you could basically use any BrowserStack API client, connect to the server and start browsers.
The included remote launcher does exactly that by wrapping BrowserStack launcher and pointing it to the given host:
launch.remote({
host : 'ie7machine',
username : 'launcher',
password : 'testing'
}, function(err, api) {
api.browsers // -> List of browsers found on ie7machine
api('http://github.com', {
browser : 'safari',
version : 'latest'
}, function(err, instance) {
});
});
