Refactoring

Prerequisite: Familiarity with the concepts introduced in Part 6 — E2E Testing Edge. Review it first if the terminology in this part is unfamiliar. Part 7 — Migration Playbook to Generative UI: Legacy to AI-Native Frontend Answer-first: Migrating a legacy React codebase to a Generative UI architecture does not require a complete application rewrite. By following a structured 4-Phase Strangler Fig Migration Playbook—Auditing UI Components (Phase 1), Extracting Component Registry Schemas (Phase 2), Deploying Edge SSE Stream Routers (Phase 3), and Incrementally Rolling Out Generative Views (Phase 4)—engineering teams migrate legacy applications safely without downtime. ...

A bulletproof AI Modernization Framework combines Golden Master (Characterization) Testing, Tree-sitter AST dependency extraction, and two-phase reasoning validation (DeepSeek-R1 / Claude 3.7) to refactor multi-thousand-line monolithic modules with zero behavioral regressions. 📖 Bản tiếng Việt (Vietnamese Edition) | ← Series Hub | Next Chapter: Part 5: Autonomous Testing & QA Automation → ...
