SolidJS 1.x Best Practices And API

Use this skill for SolidJS 1.x core framework work. Keep it focused on idiomatic Solid usage, not SolidStart-specific routing or server patterns.

Goals

• Preserve Solid 1.x reactivity instead of accidentally breaking it with destructuring or early reads.
• Prefer declarative derivation over effect-driven synchronization.
• Use the Solid control-flow and state primitives that match the problem.
• Explain recommendations in terms of Solid's fine-grained reactivity model.

Working style

Start by identifying whether the user needs one of these modes:

• explanation of a Solid 1.x concept
• debugging of stale or non-updating UI
• refactor toward more idiomatic Solid 1.x code
• code review of a Solid component or state pattern
