What is .github/CODEOWNERS

The file .github/CODEOWNERS is a special configuration file used by GitHub to define who is responsible for different parts of a repository’s codebase.

Here’s a breakdown:

📌 Location

• It lives inside the .github folder (or at the repo root).
• Common paths:
  • .github/CODEOWNERS
  • docs/CODEOWNERS
  • CODEOWNERS at the repo root

📌 Purpose

• It tells GitHub who the code owners are for specific files or directories.
• When someone opens a pull request that changes those files, the listed code owners are automatically requested for review.

📌 Example

# Global owner (applies to everything)
*       @team-leads

# Specific owners for backend
/backend/ @backend-team

# Specific file owners
/package.json @frontend-lead
Code language: PHP (php)

📌 How it Works

• GitHub matches file patterns (like .gitignore syntax).
• The last matching pattern in the file takes precedence.
• Code owners must have write access to the repository.
• They are automatically added as reviewers on PRs affecting their files.

📌 Benefits

• Clear responsibility for parts of the codebase.
• Enforced review process before merging.
• Helps large teams organize ownership and accountability.

Here’s a sample CODEOWNERS file structure you can adapt to a multi-organization / multi-team project like Wizbrand. It covers global defaults, team-specific ownership, and even individual file rules.

📌 Sample .github/CODEOWNERS

# -----------------------------------
# Global default (everything not matched below)
# -----------------------------------
*               @org-leads

/backend/        @backend-team
/backend/api/    @api-team

/infra/          @devops-team
/.github/        @ci-cd-team
/k8s/            @platform-team

# Terraform & Helm charts

📌 Explanation

• * @org-leads → Default: If no other rule matches, organization leads own it.
• /backend/ @backend-team → Whole backend directory goes to the backend team.
• backend/Dockerfile @devops-team → Specific file owned by DevOps.
• /frontend/ui/ @ui-ux-team → UI components handled by the design/UX team.
• /.github/ @ci-cd-team → All GitHub workflows and configs owned by CI/CD team.
• /docs/ @docs-team → Documentation owned by docs team, with README.md specifically assigned to docs lead.
• /secrets/ @security-team → Anything sensitive is owned by the security team.
