Installation

npm install browserstack

Usage

var BrowserStack = require("browserstack");
var browserStackCredentials = {
	username: "foo",
	password: "p455w0rd!!1"
};

// REST API
var client = BrowserStack.createClient(browserStackCredentials);

client.getBrowsers(function(error, browsers) {
	console.log("The following browsers are available for testing");
	console.log(browsers);
});

// Automate API
var automateClient = BrowserStack.createAutomateClient(browserStackCredentials);

automateClient.getBrowsers(function(error, browsers) {
	console.log("The following browsers are available for automated testing");

API

A common pattern in the APIs is a "browser object" which is just a plain object with the following properties:

• os: The operating system.
• os_version: The operating system version.
• browser: The browser name.
• browser_version: The browser version.
• device: The device name.

A browser object may only have one of browser or device set; which property is set will depend on os.

Worker objects are extended browser objects which contain the following additional properties:

• id: The worker id.
• status: A string representing the current status of the worker.
  • Possible statuses: "running", "queue".

• id: The id of the project.
• name: The name of the project.
• created_at: When the project was created.
• updated_at: When the project was most recently updated.
