Common Standards

This section outlines the core standards and practices that apply across all our engineering projects.

Overview

Our common standards ensure:

• Consistent development practices
• High code quality
• Secure development
• Efficient collaboration
• Maintainable codebase

Core Standards

1. Version Control

We follow strict Git standards including:

• Conventional commits
• Branch naming conventions
• PR review process
• Git hooks for quality

2. Security

Our security standards cover:

• Code security
• Infrastructure security
• Data protection
• Access control
• Compliance requirements

3. Documentation

We use standardized templates for:

• Project documentation
• Technical specifications
• API documentation
• Architecture decisions
• Runbooks

Quality Standards

1. Code Quality

Quality Metrics

• Test coverage: >80%
• Sonar quality gate: Pass
• No critical/blocker issues
• Documentation coverage

Linting and Formatting

We enforce consistent code style using:

{
  "extends": [
    "eslint:recommended",
    "prettier"
  ],
  "rules": {
    "no-console": "warn",
    "no-unused-vars": "error"
  }
}

Testing Requirements

• Unit tests for business logic
• Integration tests for APIs
• E2E tests for critical paths
• Performance tests for key flows

2. Code Review

Process

1. Create PR with template
2. Automated checks run
3. Request reviews
4. Address feedback
5. Merge when approved

Review Checklist

• Follows coding standards
• Includes tests
• Documentation updated
• Security considered
• Performance impact assessed

Development Workflow

1. Project Setup

All projects must include:

├── README.md           # Project overview
├── CONTRIBUTING.md     # Contribution guide
├── .gitignore         # Git ignore rules
├── .eslintrc          # Linting rules
├── .prettierrc        # Formatting rules
├── package.json       # Dependencies
├── tsconfig.json      # TypeScript config
└── docker-compose.yml # Container config

2. Development Process

graph LR
    A[Feature Branch] --> B[Development]
    B --> C[Code Review]
    C --> D[QA]
    D --> E[Staging]
    E --> F[Production]

3. Release Process

1. Version bump
2. Changelog update
3. Tag release
4. Deploy to staging
5. Verify changes
6. Deploy to production

Tools and Configurations

1. Required Tools

• Git
• Node.js
• Docker
• VS Code
• ESLint
• Prettier

2. Recommended Extensions

VS Code extensions:

{
  "recommendations": [
    "dbaeumer.vscode-eslint",
    "esbenp.prettier-vscode",
    "eamodio.gitlens",
    "ms-azuretools.vscode-docker"
  ]
}

3. Common Configurations

TypeScript Config

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "commonjs",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true
  }
}

Jest Config

module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'node',
  coverageThreshold: {
    global: {
      branches: 80,
      functions: 80,
      lines: 80,
      statements: 80
    }
  }
};

Best Practices

1. Code Organization

• Follow SOLID principles
• Use meaningful names
• Keep functions small
• Write self-documenting code
• Maintain separation of concerns

2. Error Handling

• Use typed errors
• Provide meaningful messages
• Log appropriately
• Handle edge cases
• Fail gracefully

3. Performance

• Optimize database queries
• Use caching effectively
• Minimize HTTP requests
• Implement pagination
• Monitor resource usage

Compliance

1. Code License

All internal projects must include:

Copyright (c) [Year] [Company Name]
Internal use only. All rights reserved.

2. Dependencies

• Use approved licenses only
• Keep dependencies updated
• Audit security regularly
• Document third-party usage

Support
