CODEOWNERS Overview

CodeInput enhances the standard CODEOWNERS file functionality with advanced approval workflows, automatic ownership assignment, and seamless integration with your existing development process.

What is CODEOWNERS?

CODEOWNERS is a Git convention that defines who should review and approve changes to specific files or directories in a repository. CodeInput extends this concept with powerful automation and management features.

How It Works

Define Ownership Rules

Create a CODEOWNERS file in your repository root:

# Frontend team owns all frontend code /src/frontend/* @frontend-team # Database schema requires DBA approval /migrations/* @dba-team # API changes need backend lead approval /src/api/* @backend-lead # Documentation can be approved by anyone /docs/* @docs-team

Automatic Approval Routing

When a pull request is created:

  1. File Analysis: CodeInput scans all changed files
  2. Owner Matching: Matches files to their defined owners
  3. Request Assignment: Automatically requests reviews from owners
  4. Status Tracking: Tracks approval status in real-time

Key Features

👥 Team Management

  • Dynamic Teams: Define teams with multiple members
  • Fallback Owners: Specify secondary approvers when primaries are unavailable
  • Ownership Overlap: Multiple owners for critical files
  • Nested Rules: Fine-grained control with directory-specific rules

🔔 Smart Notifications

  • Targeted Alerts: Notify only relevant code owners
  • Priority Levels: Urgent notifications for critical files
  • Consolidated Updates: Batch notifications for multiple files
  • Flexible Channels: Email, Slack, and in-app notifications

📊 Approval Analytics

  • Approval Metrics: Track average approval times
  • Bottleneck Detection: Identify slow approval processes
  • Team Performance: Compare approval efficiency across teams
  • Rule Optimization: Suggest improvements to CODEOWNERS rules

🔄 Workflow Automation

  • Auto-Assignment: Automatically assign reviewers based on file changes
  • Escalation Rules: Escalate unreviewed PRs after timeout
  • Conditional Approvals: Require additional approvals for sensitive changes
  • Merge Blocking: Prevent merging without proper approvals

Advanced Features

Pattern Matching

Use glob patterns for flexible ownership rules:

# All TypeScript files **/*.ts @typescript-team # All test files **/*.test.* @qa-team # Configuration files *.json @devops-team # Specific files /README.md @project-lead /CONTRIBUTING.md @community-manager

Team Hierarchies

Define approval hierarchies for complex workflows:

# Requires both team lead AND senior engineer /src/core/* @tech-lead @senior-engineer # Requires approval from ANY team member /src/utils/* @backend-team # Requires ALL members to approve /production/* @ops-team

Time-Based Rules

Set different rules based on schedule:

# Business hours: immediate team /urgent/* @on-call # After hours: senior staff only /production/* @senior-staff # Weekends: require additional approval /critical/* @weekend-on-call @senior-lead

Integration with CodeInput Features

Merge Conflicts

CODEOWNERS integrates with conflict resolution:

  • Owners are automatically notified of conflicts in their files
  • Conflict resolution requires owner approval
  • Historical ownership data helps resolve ambiguities

Webhooks

Configure webhooks for CODEOWNERS events:

  • New approval requests
  • Approval status changes
  • Escalation triggers
  • Rule modifications

Analytics

Track ownership patterns:

  • Most frequently approved files
  • Average approval time by team
  • Approval bottlenecks
  • Team coverage gaps

Configuration Examples

Simple Repository

# Single team owns everything * @dev-team

Multi-Team Project

# Frontend /src/components/* @frontend-team /src/styles/* @design-team # Backend /src/api/* @backend-team /src/database/* @database-team # Infrastructure /docker/* @devops-team /.github/* @platform-team # Documentation /docs/* @technical-writers

Enterprise Setup

# Executive approval for core changes /src/core/* @cto @vp-engineering # Team-specific areas /src/frontend/* @frontend-lead @frontend-team /src/backend/* @backend-lead @backend-team # Security requires CISO approval /src/auth/* @security-team @ciso /src/crypto/* @security-team @ciso # Legal review for licenses /LICENSE* @legal-team /NOTICE* @legal-team # Community contributions /contrib/* @community-managers

Best Practices

Rule Organization

  1. Start Specific: Place specific rules first
  2. End General: Use catch-all rules at the end
  3. Comment Heavily: Explain why each rule exists
  4. Regular Reviews: Update rules as teams evolve

Team Structure

  1. Keep Teams Small: 3-5 members per team
  2. Define Backups: Always have secondary approvers
  3. Clear Responsibilities: Document team ownership scope
  4. Regular Rotation: Rotate reviewers to spread knowledge

Rule Maintenance

  1. Audit Regularly: Review stale or unused rules
  2. Monitor Performance: Track approval metrics
  3. Gather Feedback: Ask teams about pain points
  4. Automate Testing: Validate rules with test PRs

Getting Started

  1. Create CODEOWNERS: Add file to your repository
  2. Define Teams: Set up teams in CodeInput
  3. Configure Rules: Add ownership patterns
  4. Test Workflow: Create test PR to verify routing
  5. Monitor Results: Track approval metrics
