Hands-on with Solid: Reactive programming with signals

"Solid.js takes a unique approach to reactive state management that has broadly influenced other reactive front-end JavaScript frameworks. It provides a compact set of reactive primitives built on signals, rather than state, and leverages those to support higher-order functionality. With a clean core design built for speed and a full set of enterprise features, Solid charted an impressive 90% developer satisfaction in the January 2025 State of JavaScript survey. Let's get started with Solid.js."

"I recently reviewed my experience using Roo Code and Gemini in VS Code, so I decided to use this AI-powered stack to generate the scaffolding for my Solid app. I also coded things manually to see how the two approaches compared. On my request, Roo Code generated the following scaffolding: npm create solid@latest -- --template typescript --name iw-solid-app Although that command is reasonable for starting a new project with a template and TypeScript,"

Solid.js uses signal-based reactive primitives instead of traditional state, enabling compact, high-performance reactive state management that influenced other frameworks. The core design emphasizes speed and supports higher-order functionality with a small API surface. Solid provides full-stack capabilities including server-side rendering and a CLI tool SolidStart for scaffolding projects. AI tools can generate scaffold commands but may not handle interactive CLI prompts reliably, so manual intervention remains necessary. Running a Solid app in development mode uses npm run dev. Developer satisfaction for Solid reached 90% in the January 2025 State of JavaScript survey.
