.tsx component templates with your preferred configuration. Instead of writing boilerplate code manually, you can select options like TypeScript, CSS approach, state management patterns (Signals, Effects, Resources), and instantly get production-ready component code that you can copy or download.
createSignal, createEffect, and createMemo for reactivity, and its JSX syntax looks very similar to React, making it easy for React developers to adopt.
createSignal(initialValue), they return a getter function and a setter function: const [count, setCount] = createSignal(0). The getter count() reads the current value, and setCount(newValue) updates it. Any reactive context (like JSX or createEffect) that calls the getter automatically subscribes to updates. When the value changes, only the specific DOM nodes or effects that depend on that signal are updated — enabling surgical precision reactivity without component re-renders.
createSignal for simple, independent pieces of state like a counter, a toggle, or a single input value. Use createStore (from solid-js/store) for nested objects and arrays where you need fine-grained reactivity on individual properties. createStore uses proxies to track property-level access, so updating one field in a nested object doesn't trigger updates for unrelated fields. For most components, createSignal is sufficient. Reach for createStore when managing complex form state or deeply nested data structures.
createEffect runs a function and automatically tracks any signals read inside it. When any tracked signal changes, the effect re-runs. It's similar to React's useEffect but with automatic dependency tracking — no dependency array needed. Effects are useful for side effects like logging, synchronizing with external systems, or manually manipulating DOM. SolidJS also provides onMount and onCleanup for lifecycle-specific operations. Remember that effects run after the DOM has been updated, ensuring you're working with the latest rendered state.
createResource is SolidJS's built-in primitive for handling asynchronous data. It takes an async fetcher function and returns a signal-like resource object with .loading, .error, and () (the resolved data). You can use it with <Show> and <Suspense> to declaratively handle loading and error states. It also supports a source signal that automatically refetches when the source changes. This eliminates the need for manual useEffect + fetch patterns common in React.
.tsx templates from this tool include proper type annotations. SolidJS's type definitions are excellent, and the community strongly recommends using TypeScript for better developer experience, autocompletion, and catching bugs early.
ref attribute: <div ref={myRef}>. The variable is assigned the actual DOM element when the component mounts. This is simpler than React's useRef — no .current needed. For callback refs, you can pass a function: <div ref={el => console.log(el)}>. SolidJS also supports directive-style refs for more advanced use cases.
