Overview

Mango provides a lot of features out of the box, but sometimes you need a feature tailored to a project, like connecting to an external API, sending event to external services, a custom data source, etc.

For these cases, you can build a Java module to do what you need, and install it like any other Mango module. In this series, we are going to build a custom module to store some energy metering devices data into Mango database, and add some REST endpoints to do operations from the frontend.

You will learn to:

• Setup development environment
• Setup the module
• Create the first endpoint
• Test your endpoint
• Query devices with RQL
• Add an AngularJS frontend
