Build better web apps faster with Claude Code skills for Next.js, TypeScript, databases, authentication, and deployment.
Web development skills that matter
Building web apps with Claude Code works well out of the box. But with the right skills from repos like anthropics/skills and antigravity-awesome-skills, you go from "works fine" to "production-ready" a lot faster.

2. TypeScript Strict Mode

Combining skills
The real value is in combinations. For a typical SaaS project, I load:

The code that comes out is well-architected, type-safe, visually polished, and tested. All from natural language prompts.

Skills don't replace your expertise. They take care of the patterns you already know, so you can focus on the hard parts.
