I built two Next.js 15 + Tailwind v4 templates with zero extra dependencies — here's what I learned

Short summary

A solo developer shipped two premium Next.js 15 + Tailwind v4 templates with zero extra dependencies, achieving ~100KB first-load JS. Key techniques include inline SVG icons, pure CSS animations, and centralizing all content in a single TypeScript config file that doubles as a compile-time content linter. The author also shares launch learnings from week one with no existing audience.

• •Zero-dependency templates using inline SVGs and pure CSS instead of icon/animation libraries
• •Single-file content config (lib/content.ts) acts as a TypeScript content linter at compile time
• •Tailwind v4 replaces tailwind.config.js with CSS-based @theme tokens; less to learn than v3
