Sauce Labs has released a new major upgrade to its Node.JS API wrapper, version v2, which includes several new features and supports additional API endpoints, including the management of real device tests and a performance API. The package was rewritten to leverage the latest Node.JS features, requiring modifications to existing projects. A CLI command is also available, allowing users to access test data and query specific endpoints by typing commands into their command line interface. The easiest way to install the package is via NPM, and configuration options can be set using environment variables or parameters. Users can access API endpoints programmatically or through a command line interface, with examples provided in the documentation. The new version encourages contributions to open source projects, including Appium and Selenium, and invites users to report issues and suggest improvements.
