Magento 2 Developer-Debug Tool, a Magento 2.0 development and debugging extension, which aims at easing developers concerns by fetching vital information for a current page load. The extension users are provided with complete set of data related to a current page request, collections and models called during a page load. Besides this, all observer called events data, along with parent and its extended classes of a page load are viewable by developers. Further, data information on blocks with their respective handle names, and associated template files with full file path is also communicated to the extension users. However, in the absence of Magento 2 Developer-Debug Tool, developers are tasked with tracking of all important data via Magento’s backend. The data in the module has been divided into tabs, which can be viewed at module’s bottom page, after it’s being configured from the admin section. Each tab is designed to allow developers to have better understanding on data related to the current page load.

• REQUEST TAB: shows the Module, Controller, Action name of the recently loaded page. Provides accurate Path Info of the loaded page, the feature help developers for URL rewriting.

• **MODEL TAB: shows all the Model Resource Name and their respective Class Name in a sequenced manner to narrate loaded models mechanism during a page load. Also mentions, frequency of instantiated models.

• COLLECTIONS TAB: shows all the active collections and its types (Flat/EAV) along with SQL Queries generated during a page load.

• OBSERVER EVENTS: shows all events and its details called during page load. Observer details like Observer Name, Observer Function, Observer Class and Observer Frequency of being instantiated are also provided.

• ALL PREFERENCES/REWRITES: shows both, all the extended classes and also the classes which extend the classes.

• HANDLES, BLOCKS AND TEMPLATES: shows all the block name of the currently loaded page with their respective handle names. Block is responsible for showing path of the template file.
