Free Quality Checklist for Developers

The Quality Checklist for Developers helps teams uphold code quality, security, performance, and project success. It offers essential practices to enhance consistency, prevent errors, optimize performance, and streamline deployment, serving as a valuable guide regardless of project size.

Instructions:

Maintain consistency by adhering to coding standards, automating tests and deployments, customizing checklists, evaluating progress, and encouraging teamwork and guideline adherence.

Code Quality

• Ensure proper indentation, consistent naming conventions (camelCase or PascalCase), and no trailing whitespaces.

• Use clear variable, function, and class names, add comments where necessary, and maintain clean, self-explanatory code.

• Avoid duplicating code. Refactor into reusable components or functions.

• Use clear error messages, handle exceptions smoothly, and log errors securely without exposing sensitive data.

Testing

• Write automated unit tests for individual functions. Aim for 80%+ test coverage.

• Write tests to validate the integration of multiple components.

• Use tools like JMeter to test system performance under high traffic.

• Use tools like Istanbul or Jest to ensure comprehensive test coverage.

Version Control

• Write clear, concise commit messages with standard prefixes (feat: fix: docs:).

• Use feature branches with descriptive names and keep them updated.

• Resolve merge conflicts promptly and ensure all tests pass after resolving conflicts.

Security

• Validate and sanitize all user inputs to protect against XSS, SQL injection, etc.

• Use encryption algorithms (e.g., bcrypt) to securely store passwords.

• Implement role-based access control (RBAC) and secure authentication tokens.

Documentation

• Document all complex logic and functions, including input/output examples.

• Maintain an up-to-date README, changelog, and installation instructions.

Deployment

• Automate build and deployment pipelines using tools like Jenkins and CircleCI.

• Use environment variables for configurations, and ensure proper separation of environments (development, staging, production).

• Establish clear rollback procedures in case of deployment failure.

Performance Optimization

• Test the system under different traffic conditions to identify bottlenecks.

• Use profiling tools like Chrome DevTools or New Relic to identify slow functions or performance issues.

• Implement caching strategies for frequently accessed data to reduce database load (e.g., Redis, Memcached).

Compliance

• Ensure compliance with open-source licenses (e.g., MIT, GPL).

• Comply with GDPR/CCPA using access controls, consent management, and data anonymization.

By following this Developer Quality Checklist, [Your Company Name] ensures secure, scalable, and maintainable high-quality code, fewer bugs, smooth deployments, and an efficient development process. Stay disciplined and committed to these standards for continuous success.
