# node-browserstack

A node.js JavaScript client for working with [BrowserStack](http://browserstack.com) through its [REST API](https://github.com/browserstack/api) (*aka* Javascript Testing API), [Automate API](https://www.browserstack.com/automate/rest-api) and [Screenshots API](https://www.browserstack.com/screenshots/api).

Support this project by [donating on Gratipay](https://gratipay.com/scottgonzalez/).

## Installation

```
npm install browserstack
```

## Usage

```javascript
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");
	console.log(browsers);
});

// Screenshots API
var screenshotClient = BrowserStack.createScreenshotClient(browserStackCredentials);

screenshotClient.getBrowsers(function(error, browsers) {
	console.log("The following browsers are available for screenshots");
	console.log(browsers);
});
```

## API

### Objects

#### browser objects

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

Worker objects are extended [browser objects](#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"`.

#### project objects

Project objects are plain objects which contain the following properties:

* `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.
* `user_id`
* `group_id`

#### build objects

Build objects are plain objects which contain the following properties:

* `hashed_id`: The hashed if of the build.
* `name`: The name of the build.
* `status`: The status of the build.
* `duration`

#### extended build objects

Extended build objects are [build objects](#build-objects) with the following additional properties:

#### session objects

Session objects are extended [browser objects](#browser-objects) which contain the following additional properties:

* `hashed_id`: The hashed ID of the session.
* `name`: The name of the session.
* `build_name`: The name of the build this session belongs to.
* `project_name`: The name of the project this session belongs to.

* `logs`: The URL for the session logs.
* `video_url`: The URL for the session video.
* `reason`: The reason the session was terminated.

#### screenshot job objects

Screenshot job objects are plain objects which contain the following properties:

* `quality`: The quality of the screenshot. May be one of: `"original"`, `"compressed"`.
* `wait_time`: The number of seconds to wait before taking the screenshot. May be one of: `2`, `5`, `10`, `15`, `20`, `60`.
* `local`: Boolean indicating whether a local testing connection should be used.

### screenshot state objects

Screenshot state objects are extended [browser objects](#browser-objects) which contain the following additional properties:

* `id`: The id of the screenshot object.
* `state`: The state of the screenshot.
* `url`: The URL of the page the screenshot was generated from.
