Refactoring Imperative Code to fp-ts
This skill provides comprehensive patterns and strategies for migrating existing imperative TypeScript code to fp-ts functional programming patterns.
Detailed Guide
Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.
When to Use
- You are refactoring an existing imperative TypeScript codebase toward fp-ts patterns.
- The task involves converting
try/catch, null checks, callbacks, DI, or loops into functional equivalents. - You need migration guidance and tradeoffs, not just isolated fp-ts examples.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
