## Memory Protocol (MANDATORY)

**Before starting:**

```bash
cat .claude/context/memory/learnings.md
```

**After completing:** Record any new patterns or exceptions discovered.

Overview

This skill is a SolidJS expert that helps developers improve reactivity, components, and state patterns across applications. I provide concrete guidance, code reviews, refactors, and architecture recommendations aligned with Solid best practices. My advice focuses on predictable reactivity, performance, and maintainable folder structure.

How this skill works

I inspect code for correct use of Solid primitives (createStore, createResource, createMemo, Show, For) and recommend replacements or refactors when patterns are anti-patterns. I point out where to add error boundaries, lazy loading, and optimization hooks, and I propose folder and naming layouts for clarity. When requested, I produce example components or refactors demonstrating the preferred approach.

When to use it

  • Review or refactor code that mixes mutable state with reactive signals
  • Design complex state solutions that require nested updates and transactions
  • Implement data fetching with lifecycle-aware caching and loading states
  • Optimize derived values to avoid unnecessary recomputation
  • Introduce error boundaries or lazy-loaded routes/components

Best practices

  • Use createStore() for complex, nested, or shared state to get structural updates and transactions
  • Use createResource() for async data tied to reactive sources and automatic caching
  • Wrap conditional rendering with <Show> and lists with <For> for efficient DOM updates
  • Use createMemo() for derived computations to memoize and avoid extra reactivity
  • Always write functional components with JSX templates; prefer lazy() for large routes
  • Add error boundaries around async or risky subtrees and follow Solid naming conventions

Example use cases

  • Refactor a complex form and use createStore() to manage nested fields and transactions
  • Replace imperative list rendering with <For> plus keyed updates to improve performance
  • Convert fetch-based effects to createResource() to get loading, error, and cache states
  • Introduce createMemo() for expensive filters and sorting to reduce recomputation
  • Structure a new project with src/components, src/pages, src/utils, and App/ index entry points

FAQ

When should I prefer createStore over signals?

Prefer createStore for deeply nested or frequently updated shared state; use signals for simple, local primitive values.

How do I handle data fetching with reactivity?

Use createResource tied to a reactive source so fetching, caching, loading, and errors integrate with the reactive graph automatically.
