How to Run Dependency Reports in Magento 2

Magento 2 comes with many changes, and one of the major changes in Magento 2 is the usage of dependency injection and dependency report patterns. With these patterns, a lot has changed inside the codebase, and many new things have been introduced. In this article, I am going to talk about Dependency reports and how you can run them in Magento 2.

In Magento 2, there are three types of dependencies reports, they are:

1. Module dependencies: It shows the total number of dependencies among modules and whether the dependencies are hard or delicate.
2. Circular dependencies: It shows the total number of dependency chains and circular dependency for modules.
3. Framework dependencies: It shows the number of dependencies on the Magento 2 framework by a module.

Preparing To Run Dependency Reports

Before run dependency reports, you need to follow these steps:

• Login to the Magento 2 server and switch to a user who has permissions to write Magento 2 file system.
• Open your SSH terminal and use the following command to switch to the Magento 2 file system owner:

find . -type d -exec chmod 770 {} \; && find . -type f -exec chmod 660 {} \; && chmod u+x bin/magento
export PATH=$PATH:$(pwd)/bin

Run Dependency Reports

For running the dependency reports on your Magento 2, use this following command:

magento info:dependencies:{show-modules|show-modules-circular|show-framework} [-d|--directory=""] [-o|--output="

Confused as to what these commands mean? Here are the meanings of this commands options, values, and parameters:

• show-modules: This Parameter is required for getting module dependencies report.
• show-modules-circular: This Parameter is required for getting Circular dependencies report.
• show-framework: This Parameter is required for getting Framework dependencies report.

Module Dependencies Report

Below is the output for a module dependencies report:

"","All","Hard","Soft"
