description: Safely refactors legacy codebases using specific techniques such as dependency analysis, strangler fig pattern, and port isolation to ensure clean modularity and enhanced collaboration.
license: MIT compatibility: opencode metadata: version: "1.0.0" archetypes:
A structured approach to refactoring legacy codebases in a safe manner that emphasizes collaboration among developers and stakeholders. Utilizing principles from atomic design and modularity ensures each component can be tested and maintained independently.
This example demonstrates how code can be improved by focusing on modular design:
# ─── BEFORE: Coupled Legacy Code ───────────────────────
class Order:
def __init__(self, item):
self.item = item
self.status = 'Pending'
def process_order(self):
# Complex logic intertwined with multiple system calls
if some_external_condition:
self.status = 'Processed'
else:
raise Exception("Processing failed")
# ─── AFTER: Modular and Testable Design ──────────────
class Order:
def __init__(self, item: str):
self.item = item
self.status = 'Pending'
def process(self, processor: OrderProcessor):
self.status = processor.process(self.item)
class OrderProcessor:
def process(self, item: str) -> str:
# Encapsulates processing logic without side effects on the component
return 'Processed'
When transitioning to a new module, utilize the strangler fig pattern.
# ─── Setting up the Strangler Proxy ──────
class StranglerProxy:
def __init__(self):
self.routes = {
"GET /api/orders": self.old_order_system,
"POST /api/orders": self.new_order_system,
}
def forward_request(self, path):
target = self.routes.get(path)
if target:
return target()
raise Exception("Route not found")
# Legacy Order System Logic
def old_order_system():
# Logic of the old implementation
return "Old order response"
# New Order System Logic
def new_order_system():
# Logic of the new implementation
return "New order response"
