Can i know what is the major difference between perspective module and web dev module? There is any possibility to develop dynamic dashboards in web dev module ?
The web dev module is for interfacing with just about anything that can communicate over the web. Perspective is for creating full front end gui interfaces that operate in a web browser.
If you are needing to create some type of user interface from scratch, you want Perspective. If you are needing to host an existing web page or create a custom API for a web enabled device, then you want Web Dev.
Think of Web Dev as a way to host resources and make them available through your Gateway: images, data (via HTTP endpoints), reports.
Perspective is a full-fledged visualization module - very similar to the Vision module - which allows for developing projects to be consumed via a web browser. This is different from Vision, where the project user must make use of a Java client to view the project, and the technology differences between Vision and Perspective bring several limitations and advantages.
Do you already use Vision?
