How to Add a New Endpoint

Example: Adding a new game feature

1. Choose the right router based on feature:

   • Player actions → game_routes.py
   • Combat → combat.py
   • Items → equipment.py or crafting.py
   • New category → Create new router file

2. Add endpoint to router:

# In api/routers/game_routes.py

@router.post("/api/game/new_action")
async def new_action(
    request: NewActionRequest,
    current_user: dict = Depends(get_current_user)
):
    """Your new endpoint"""
    # Your logic here
    return {"success": True}

3. Add model if needed (in api/services/models.py):

class NewActionRequest(BaseModel):
    action_param: str

4. No need to touch main.py - routers auto-register!

How to Find Code

Before Migration:

• "Where's the movement code?" → Scroll through 5,573 lines 😵

After Migration:

• Movement → api/routers/game_routes.py line 200-300
• Combat → api/routers/combat.py
• Equipment → api/routers/equipment.py
• Auth → api/routers/auth.py

Common Tasks

Adding a New Pydantic Model:

→ Edit api/services/models.py

Changing Configuration:

→ Edit api/core/config.py

Modifying Auth Logic:

→ Edit api/core/security.py

Adding Helper Function:

→ Edit api/services/helpers.py

Creating New Router:

1. Create api/routers/new_feature.py
2. Add router initialization function:

LOCATIONS = None
ITEMS_MANAGER = None

def init_router_dependencies(locations, items_manager, world):
    global LOCATIONS, ITEMS_MANAGER
    LOCATIONS = locations
    ITEMS_MANAGER = items_manager

router = APIRouter(tags=["new_feature"])

3. Import in main.py:

from .routers import new_feature

4. Initialize dependencies:

new_feature.init_router_dependencies(LOCATIONS, ITEMS_MANAGER, WORLD)

5. Register router:

app.include_router(new_feature.router)

Restart API After Changes

cd /opt/dockers/echoes_of_the_ashes
docker compose restart echoes_of_the_ashes_api
docker compose logs -f echoes_of_the_ashes_api

Backup Files (Safe to Keep)

• api/main_original_5573_lines.py - Original massive file
• api/main_pre_migration_backup.py - Pre-migration backup

What Changed vs What Stayed the Same

Changed ✅:

• File organization (one big file → many small files)
• Import statements
• Router registration

Stayed the Same ✅:

• All endpoint logic (100% preserved)
• All functionality (zero breaking changes)
• Database queries
• Game logic
• Business rules

Benefits for You

1. Finding code: 10x faster
2. Adding features: Just pick the right router
3. Understanding code: Each file has a clear purpose
4. Debugging: Smaller files = easier to debug
5. Collaboration: Multiple people can work on different routers

Need to Rollback?

If something goes wrong (it won't, but just in case):

cd /opt/dockers/echoes_of_the_ashes/api
cp main_original_5573_lines.py main.py
docker compose restart echoes_of_the_ashes_api

Happy coding! Your codebase is now clean, organized, and ready for future growth. 🚀
