Project Concept

Extensions enable you to quickly and easily add new functionality to an IoT solution. Extensions can be service (function/method) libraries, connector templates, functional widgets, and more.

The Eclipse Plugin for ThingWorx Extension Development (Eclipse Plugin) is designed to streamline and enhance the creation of extensions for the ThingWorx Platform. The plugin makes it easier to develop and build extensions by automatically generating source files, annotations, and methods as well as updating the metadata file to ensure the extension can be imported.

These features allow you to focus on developing functionality in your extension, rather than worrying about getting the syntax and format of annotations and the metadata file correct.
