Coding and Design Guidelines

Welcome to the Artemis Coding and Design Guidelines. These guidelines help maintain code quality, consistency, and best practices across the project.

⚠️

UI/UX Guidelines

For all UI-related development work, you must follow the AET UI/UX Guidelines. These external guidelines cover design principles (simplicity, consistency, feedback, accessibility, learnability), general conventions, accessibility standards, and component styling (buttons, headings, spacing, colors).

The Artemis-specific guidelines below focus on implementation details for Angular/TypeScript development, while the AET UI/UX Guidelines define the design standards you must follow.

Client Guidelines​

Guidelines for Angular/TypeScript frontend development:

  • Client Development - Angular development practices, naming conventions, components, and advanced topics
  • Client Theming - Theme management, color usage, and styling guidelines
  • Client Tests - Testing practices, mocking strategies, and coverage standards

Server Guidelines​

Guidelines for Spring Boot/Java backend development:

  • Server Development - Java best practices, project structure, REST APIs, and authorization
  • Server Tests - Server testing strategies, ArchUnit, and performance tips
  • Database - Database design, relationships, cascade types, and dynamic fetching
  • Performance - Performance optimization, data economy, paging, and query optimization
  • Criteria Builder - Type-safe dynamic queries using JPA Criteria API

General Guidelines​

  • Language - Inclusive, diversity-sensitive, and appreciative language guidelines

Key Principles​

ℹ️

Code Quality First

  • Prioritize code quality and test coverage
  • Reuse code and avoid duplication
  • Write meaningful tests
  • Follow established patterns and conventions
⚠️

Performance Matters

  • Write performant queries that scale to 1000+ objects
  • Use lazy loading by default
  • Implement proper caching strategies
  • Avoid N+1 query problems
❗

Security is Critical

  • Never trust user input
  • Always validate and sanitize data
  • Use proper authorization checks
  • Follow the principle of least privilege
