SolidJS Component Scaffold - Online Quick .tsx Template

This tool helps you quickly generate SolidJS .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.

SolidJS is a declarative JavaScript library for building reactive user interfaces. Unlike React, which uses a Virtual DOM and re-renders components on state changes, SolidJS compiles directly to fine-grained reactive DOM updates without a Virtual DOM. This means no re-renders — only the specific DOM nodes that depend on changed data are updated. SolidJS uses createSignal, createEffect, and createMemo for reactivity, and its JSX syntax looks very similar to React, making it easy for React developers to adopt.

Signals are the core reactive primitive in SolidJS. Created with 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.

Use 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.

Absolutely! SolidJS has first-class TypeScript support. You can define props interfaces, type signals, and use all TypeScript features seamlessly. The generated .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.

SolidJS works well with any CSS approach: CSS Modules (great for scoped styles, supported out of the box by most bundlers like Vite), Tailwind CSS (utility-first, excellent DX), CSS-in-JS libraries, or plain CSS files. CSS Modules are particularly popular in the SolidJS ecosystem because they provide component-scoped class names without runtime overhead. Tailwind CSS is also widely used for rapid prototyping and consistent design systems. This tool lets you choose your preferred approach.

In SolidJS, you can get a reference to a DOM element by declaring a variable and using the 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.

Yes! SolidJS is production-ready and used by companies in real-world applications. It consistently ranks among the top-performing JavaScript frameworks in benchmarks (often #1 or near the top). Its small bundle size (around 7KB gzipped), fine-grained reactivity, and excellent performance make it ideal for performance-sensitive applications. The ecosystem includes Solid Router, Solid Query (TanStack Query adapter), Meta (for SEO), and integration with major UI libraries. Combined with TypeScript and Vite, SolidJS provides a robust foundation for building scalable web applications.
