Learn SOLID-JS with Real Code Examples
Updated Nov 22, 2025
Practical Examples
Real-time stock dashboard
Counter app using signals
Chat app with live updates
Widget embedded in existing websites
Streaming SSR blog or e-commerce UI
Troubleshooting
Check if signals are called as functions
Avoid mutating primitives directly
Ensure effects do not create infinite loops
Debug hydration mismatches in SSR apps
Check Vite configuration for JSX settings
Testing Guide
Use Vitest for unit testing
Use @solidjs/testing-library for components
Mock signals and stores
Test reactive flows and effects
Snapshot test JSX output
Deployment Options
Deploy static output with Netlify or Vercel
Use Solid Start for SSR on Node servers
Embed widgets directly into websites
Deploy SPA via Cloudflare Pages
Use Docker for containerized apps
Tools Ecosystem
Solid Router for SPA navigation
TanStack Query for data fetching
Vite for bundling
Vitest for testing
Solid Start (meta-framework for SSR)
Integrations
REST APIs and GraphQL
WebSockets for real-time UI
TailwindCSS, UnoCSS for styling
Firebase or Supabase backend
PWAs with Vite plugins
Productivity Tips
Use signals instead of stores when possible
Leverage JSX compilation for performance
Use context sparingly
Keep effects pure and side-effect-only
Use Solid DevTools extension
Challenges
Build a counter with fine-grained reactivity
Create a todo app with stores
Build a small SPA with Solid Router
Implement global state using context
