What is SolidJS?
A JavaScript framework that compiles component templates directly to DOM nodes and keeps them efficiently synchronized with application state changes through fine-grained reactivity, without a virtual DOM.

SolidJS FAQ
Common questions about SolidJS, answered from independent, dated evidence.
What is SolidJS and how does it work?
SolidJS is a JavaScript library for building user interfaces using a declarative programming model with JSX. Unlike frameworks that use a virtual DOM, SolidJS compiles templates directly into real DOM nodes and updates them through fine-grained reactivity, where only code dependent on changed state will re-execute. This approach results in smaller bundle sizes and optimal runtime performance.

How does SolidJS differ from React?
SolidJS uses fine-grained reactivity and direct DOM compilation instead of React's virtual DOM reconciliation. In SolidJS, components are functions that run once, and only the specific reactive values that change trigger updates, whereas React re-renders components when state changes. This typically results in better performance and smaller compiled bundle sizes compared to React applications.

Is SolidJS open-source and what license does it use?
Yes, SolidJS is completely open-source and free to use under the MIT license. The MIT license permits both commercial and personal use, modification, and distribution without cost or licensing restrictions.

Does SolidJS support TypeScript?
Yes, SolidJS has first-class TypeScript support and is built on JSX and TypeScript. To use TypeScript with SolidJS, you configure your tsconfig.json with jsx set to 'preserve' and jsxImportSource set to 'solid-js'. This provides full type safety for components, props, and reactive state.

What does 'fine-grained reactivity' mean in SolidJS?
Fine-grained reactivity refers to a system where the framework tracks which pieces of code depend on which data, and only re-executes the code that depends on changed values. In SolidJS, when state changes, only the specific DOM updates and side effects that depend on that state will run, rather than re-rendering entire components. This precision minimizes unnecessary computation and DOM manipulation.

What can I build with SolidJS?
SolidJS is suitable for building interactive web applications, single-page applications (SPAs), and progressive web apps. It supports server-side rendering with progressive hydration, error boundaries, suspense for async operations, and context-based state management. The framework also enables authoring custom web components for reusable UI elements.

What build tools and ecosystem does SolidJS have?
SolidJS integrates with modern build tools like Vite and includes ecosystem libraries for state management (built-in Stores and Context), component libraries like Kobalte, and community packages like solid-primitives. The framework also works well with standard JavaScript libraries that directly manipulate the DOM, such as D3 for data visualization.

Does SolidJS use a virtual DOM?
No, SolidJS does not use a virtual DOM. Instead, it compiles JSX templates directly into real DOM nodes at build time. This direct compilation approach eliminates the overhead of virtual DOM diffing and contributes to SolidJS's performance advantages and smaller bundle size.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for SolidJS, not the verdict.
