Code Review

Review code for SolidJS, TypeScript, and component design issues.

Instructions

When reviewing code:

1. Read the file(s) to be reviewed
2. Check against patterns in the reference files below
3. Report findings organized by severity

Reference Files

Load these for detailed patterns when needed:

• solidjs-patterns.md - Reactivity, signals, effects, stores
• typescript-patterns.md - Type safety, strict mode, unions
• component-design.md - SOLID principles, composition

Quick Checks

SolidJS Critical Issues

• Props destructured (breaks reactivity)
• Signal not called as function in JSX
• createEffect used for derived state
• Missing onCleanup for subscriptions

TypeScript Critical Issues

• any type usage
• Missing exhaustive switch check
• Type assertion without validation
• Untyped external data

Component Critical Issues

• God component (>300 lines, multiple concerns)
• Prop drilling through 3+ levels
• Direct API imports (not injected)

Output Format

## Critical Issues
[Must fix - causes bugs]

## Anti-Patterns
[Should fix - violates best practices]

## Suggestions
[Optional improvements]

Project Rules (VSTGUI-Edit)

Also check:

• No React imports (only solid-js)
• No dynamic imports (static only)
• CSS modules only (*.module.css)
• Tests colocated as *.spec.tsx
