Deprecation and Migration
Overview
Treat code as a liability that must justify its existence. Deprecate deliberately, migrate incrementally, and remove dead code systematically. Every line of code you remove is a line you never have to maintain again.
When to Use
- Removing old APIs or features
- Migrating users from one system to another
- Cleaning up unused code
- Replacing deprecated dependencies
Deprecation Types
Advisory Deprecation
- Mark as deprecated in documentation and type annotations
- Log warnings when the deprecated path is used
