Developer Guidelines

Introduction

These developer guidelines provide a framework for maintaining consistency, efficiency, and best practices in our development processes. Adhering to these guidelines will help us produce high-quality software and collaborate effectively within our development teams.

Principles

SOLID, KISS, YAGNI and DRY

1. SOLID Principles

   • Single Responsibility Principle (SRP): Each class or module should have only one reason to change.
   • Open-Closed Principle (OCP): Software entities should be open for extension but closed for modification.
   • Liskov Substitution Principle (LSP): Subtypes must be substitutable for their base types without altering the correctness of the program.
   • Interface Segregation Principle (ISP): Clients should not be forced to depend on interfaces they do not use.
   • Dependency Inversion Principle (DIP): High-level modules should not depend on low-level modules; both should depend on abstractions.

2. KISS (Keep It Simple, Stupid)

   • Strive for simplicity in design and code. Avoid unnecessary complexity.
   • Write code that is easy to read and understand.

3. YAGNI (You Aren't Gonna Need It)

   • Don't add features or code that you anticipate needing in the future but do not currently need.
   • Focus on delivering functionality required by the present requirements.

4. DRY (Don't Repeat Yourself)

   • Avoid duplicating code or logic in multiple places.
   • Use abstractions to avoid repeating code.

Dependency Injection

1. Dependency Injection

   • Use dependency injection to decouple components and facilitate testing and maintainability.
   • Avoid hard-coding dependencies in classes and modules.

2. Inversion of Control

   • Use inversion of control containers to manage dependencies and object lifetimes.
   • Avoid manually managing object lifetimes.

Separation of Concerns

1. Separation of Concerns

   • Separate concerns into distinct modules, classes, and functions.
   • Avoid mixing unrelated functionality in the same module, class, or function.

2. Single Responsibility Principle

   • Follow the single responsibility principle to ensure that each module, class, or function has only one reason to change.
   • Use descriptive names for modules, classes, and functions to indicate their purpose.

Development Process

Agile and Scrum

1. Agile Methodology

   • Embrace the Agile development methodology, which emphasizes iterative and collaborative development.

2. Scrum

   • Follow Scrum practices for project management, including regular sprint planning, daily stand-ups, sprint reviews, and retrospectives.
   • Collaborate with cross-functional teams to achieve project goals.

CI/CD

1. Continuous Integration

   • Use continuous integration to automate the build and testing of code changes.
   • Ensure that code changes are tested and merged into the main branch frequently.
   • Use a CI tool such as Jenkins to automate the build and testing process.

2. Continuous Delivery

   • Use continuous delivery to automate the deployment of code changes to production.
   • Ensure that code changes are deployed to production frequently.
   • Use a CD tool such as ArgoCD to automate the deployment process.

Gitflow Workflow

1. Gitflow Workflow

   • Use the Gitflow workflow to manage code branching and releases.
   • Follow the branching strategy of feature branches, develop, release, and master branches.

2. Version Control

   • Commit frequently with clear and descriptive commit messages.
   • Ensure code changes are well-documented in pull requests.

Coding Standards

1. Code Consistency

   • Adhere to a consistent code style guide (e.g., PEP 8 for Python, ESLint for JavaScript) for the respective programming language.
   • Use meaningful variable and function names.

2. Code Reviews

   • Conduct thorough code reviews to identify and address issues related to code quality, security, and maintainability.

3. Testing

   • Write unit tests for code to ensure functionality and catch regressions.
   • Implement automated testing wherever possible.

4. Documentation

   • Document code, APIs, and configuration as necessary to facilitate understanding and maintenance.

5. Performance

   • Optimize code for performance when required, but avoid premature optimization.

6. Security

   • Follow secure coding practices to prevent common security vulnerabilities.

7. Naming Conventions

   • Use descriptive names for variables, functions, classes, and modules.
   • Use consistent naming conventions for variables, functions, classes, and modules.

Conclusion

By following these developer guidelines, we aim to foster a culture of collaboration, quality, and efficiency in our development efforts. Regularly reviewing and updating these guidelines will ensure that our development processes remain effective and aligned with industry best practices.
