Codebase Insights Visualization for IntelliJ IDE

Almost every professional programmer knows the struggle of trying to understand another person's code when joining a new project.

In Nov-Dec. 2021, my team and I developed a plugin for IntelliJ IDE that provides a visualization of a codebase to idenitfy the architecture "hot-spots." Every file is displayed with a "heat color" to identify the potentially problematic files in a project according to its commit history, number of authors, and file size, which my team and I collect from GitHub.

For example, a file that developers continue to make commits to long after the file was originally written is a warning sign for the architecture of that file. We also offer the capability to group files based on how often they appear in together in the same commit so that a hot file may tell a user to refactor that file or be aware of changes they need to make in other files in order to update one particular file.

• Each file is given a heat color based on either:
• Number of commits
• Number of authors
• File size
• Overall (weighted total of all the above metrics)
• Selecting a branch lets one see if the code truly improved over time
• Files are grouped based on either:
• Their package
• Which files they appeared in the same commits with

Commit History

• Shows every commit a file was modified in

Commit Details
