Full-Stack Signals in Solid, AI Development, and the Future of Web Frameworks

In this episode of What's Good, Joel Hooks sits down with Dev Agrawal, a member of the SolidJS core team, to discuss the evolving landscape of web development, AI-assisted coding, and modern framework architecture.

Episode Highlights

SolidJS and Modern Framework Architecture

• Detailed comparison between SolidJS and React, highlighting key advantages
• Deep dive into Suspense implementation and reactive state management
• Overview of Dev's work on cross-boundary reactivity in SolidJS
• Discussion of his $7,000 Solid Hack competition winning project
• Exploration of stateful server components with WebSocket updates

AI-Assisted Development

• Discussion of AI agents managing tasks and grooming backlogs during meetings
• Exploration of using AI tools like Cursor for development
• Joel shares his experience building JoelFit, a full-stack application developed primarily through AI prompting
• Analysis of AI's current limitations and the importance of human guidance in development

Emerging Technologies and Trends

• Analysis of React Server Components and their impact on the ecosystem
• Discussion of Cloudflare Durable Objects as individual compute units
• Introduction to Zero Sync and its implications for local-first applications
• Exploration of incremental view maintenance and its performance benefits
• Overview of Vite 6's improvements for server components and meta frameworks

Featured Projects and Resources

• JoelFit (code) - Joel's AI-assisted development project on github
• Solid Suspense Demo v2 - Dev's demo showcasing Solid's advantages
• Building Asynchronous UIs Without the Hassle - Dev's conference talk

Key Takeaways

• SolidJS offers built-in support for async operations without React's bailout issues
• The entire Solid ecosystem was built with suspense support from v1
• Durable Objects are often misunderstood - they're individual compute units rather than just shared state
• Zero Sync's incremental view maintenance pairs particularly well with Solid's architecture
• React has moved away from traditional SPA towards full-stack architecture
• Framework choices continue to evolve with different approaches to reactivity and state management
