Create An Extension Part 1

100% helpful (2/2)

 

 

Build extensions quickly and extend your application functionality with the Eclipse Plugin.

 

GUIDE 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.

 

YOU'LL LEARN HOW TO

 

  • Install the Eclipse Plugin and Extension SDK
  • Create and configure an Extension project
  • Create Services, Events and Subscriptions
  • Add Composer entities
  • Build and import an Extension

 

NOTE: This guide's content aligns with ThingWorx 9.3. The estimated time to complete all parts of this guide is 60 minutes.

 

Step 1: Completed Example

Step 2: Download Plugin and SDK 

 

The ThingWorx Extension SDK provides supported classes and APIs to build Java-based extensions. The APIs included in this SDK allow manipulation of ThingWorx platform objects to create Java based extensions that can extend the capability of the existing ThingWorx platform.

 

The Eclipse Plugin assists in working with the Extension SDK to create projects, entities, and samples.

  1. Download the Eclipse Plugin.

  2. Download the Extension SDK..

  3. Make a note of the directory where the plugin and the extension SDK are stored. The path of the directory will be required in upcoming steps. Do not extract the zip files.

 

 

Step 3: Install and Configure

 

Before you install the plugin, ensure that software requirements are met for proper installation of the plugin.
