solidjs

SolidJS is a declarative JavaScript library for building user interfaces with fine-grained reactivity. Unlike virtual DOM frameworks, Solid compiles templates to real DOM nodes and updates them with fine-grained reactions. Options: Key behaviors: Use memos when: For nested objects/arrays with fine-grained updates: Store utilities: Props rules: Note: index is a signal, item is the value. Note: item is a signal, index is the value. Better for primitive arrays or inputs. See references/routing.md for complete routing guide. Quick setup: See references/solidstart.md for full-stack development guide. Quick setup: vite.config.ts: Destructuring props — Breaks reactivity Accessing signals outside tracking scope Forgetting to call signal getters Using array index as key — Use for reference-keyed, for index-keyed Side effects during render — Use createEffect or onMount - Components run once — Component functions execute only during initialization, not on every update - Fine-grained reactivity — Only the specific DOM nodes that depend on changed data update - No virtual DOM — Direct DOM manipulation via compiled templates - Signals are functions — Access values by calling: count() not count - Initial run: after render, before browser paint - Subsequent runs: when tracked dependencies change - Never runs during SSR or hydration - Use onCleanup for cleanup logic - Derived value is...
