Patterns and Examples
This is where everything comes together. You've learned the language, you understand the runtime, and now you want to actually build things. These chapters collect practical patterns and complete working examples -- the stuff that emerges from actually using Adama to solve real problems.
Chapters
1. Common Patterns
Foundational patterns that show up in nearly every Adama application:
- Authentication and Sessions: Managing user identity and connection lifecycle
- Role-Based Access Control: Implementing permission systems with policies
- Optimistic Updates: Providing instant feedback while maintaining consistency
- Conflict Resolution: Handling concurrent modifications gracefully
- Pagination: Efficiently displaying large datasets
- Search and Filtering: Building dynamic query interfaces
2. Game Patterns
Patterns specifically for multiplayer games (which, honestly, is where Adama really shines):
- Turn-Based Structure: Managing player turns and game phases
- Player Management: Joining, leaving, and reconnecting
- Game State Machines: Modeling game flow with states
- Scoring and Leaderboards: Tracking and displaying rankings
- Timer-Based Mechanics: Implementing time limits and countdowns
- Undo/Redo: Supporting move reversal and history
3. Complete Examples
Full, runnable applications demonstrating patterns in context:
- Real-Time Chat Room: Messages, users, typing indicators, and presence
- Simple Card Game: Deck management, hands, turns, and win conditions
- Collaborative Todo List: Tasks, assignments, completion tracking, and filtering
How to Use This Section
If you're new to Adama, start with Common Patterns. These are the techniques that will serve you regardless of what you're building.
If you're building a game, the Game Patterns chapter addresses the specific challenges of multiplayer game development -- turn management, hidden information, leaderboards, the works.
If you learn by reading code, jump straight to Complete Examples. Each one is a full application with all the pieces working together, and I've included commentary on why things are structured the way they are.
Pattern Conventions
Throughout this section, patterns are presented with:
- Problem Statement: What challenge the pattern solves
- Solution: The Adama code implementing the pattern
- Explanation: Why this approach works
- Variations: Alternative implementations for different requirements
Code examples are complete and can be run directly in Adama.
