Magento 1 was a quite complex framework and its new version 2 is nothing simplier to use, expecially if you are not 100% Magento confident or a Magento super-hero.

Some of the most time consuming in Magento are:

  • Find out where is the layout XML file I have to change
  • Find out what is the right template file
  • Find out what is the uiComponent involved and where is its template
  • Find out where and why an observer is called
  • Find out where are my template bottlenecks
  • Find out where are my backend bottlenecks

In a short way: The main time consuming stuff in Magento is: To find out something.

Here at the MageSpecialist headquarters we decided to create a new module to help people in Magento developing and give them a convenient tool to quickly debug and locate files they need.

After some week of hard work converting caffeine to code, we deployed beta version of MSP_DevTools module both for Magento 1 and Magento 2. This module integrates Chrome developer toolbar for a very quick access to Magento information. You will just need to open Chrome developers toolbar (SHIFT + CTRL + I).

How it Works

In order to use MSP_DevTools you have to download both Chrome Extension and Magento Extension.
Installation details are available in our GitHub page here: .
Chrome Extension is also available in the Chrome WebStore.

Once you have installed and enabled Magento module you can enable Magento debug features in Chrome simply pressing extension icon. This will seamlessly display additional “Magento” tabs in Chrome developer toolbar and in its inspector panel.

Chrome Inspector integration

One the most amazing feature of MageSpecialist DevTools is the Chrome Inspector Integration that display all blocks information you need in one click. In Magento 2 it also supports uiComponents and Containers inspection.

A convenient PhpStorm integration allows you to directly open your required block’s template file in on click.
