Git & GitHub Interview Question #79

What is CODEOWNERS on GitHub?

GitHub Collaboration, Repository Rules, Issues, Releases & Actions CI/CD Mid-Level Intermediate

Quick Interview Answer

A CODEOWNERS file maps repository paths or patterns to users or teams that are responsible for reviewing those areas. GitHub can automatically request matching code owners when a pull request changes owned files.

Detailed Explanation

When repository rules require code-owner approval, a pull request may not be mergeable until an appropriate owner approves it. The CODEOWNERS file itself is stored in the repository.

Code Example

# Example CODEOWNERS entries

# Default owners
* @organization/core-team

# MVC views
/Views/ @organization/frontend-team

# Database code
/Data/ @organization/backend-team
