solid-core-primitives

What problem does it solve?

This Skill clarifies the core reactivity primitives in SolidJS, helping developers understand how to build performant, fine-grained applications without component re-renders.

Core Features & Use Cases

• Fine-Grained Reactivity: Understand how SolidJS updates only the necessary DOM nodes.
• Signals: Learn to create and manage reactive state with createSignal.
• Components: Grasp that SolidJS components run once and rely on reactive primitives for updates.
• Effects: Implement side effects and subscriptions using createEffect.
• Stores: Manage complex state with direct property access and path-based updates.
• Memos: Create cached, computed values with createMemo.
• Use Case: Quickly onboard new team members to SolidJS by providing them with a clear, concise guide to its fundamental building blocks.
