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

Earlier this month I shipped two premium templates - a SaaS landing page and a developer portfolio. Not a startup, not a SaaS, just templates. This post is about the two constraints I built them under, why they made the code better, and a few things I learned launching as a solo dev with zero audience.

Constraint 1: zero dependencies beyond next, react, and tailwind

Open the package.json of most templates and you'll find 20+ packages: icon libraries, animation libraries, carousel plugins, UI kits, utility libraries. Every one of them is a version conflict waiting to happen for the buyer, and most are replaceable with a few lines of code in 2026.

What I used instead:

• Icons → inline SVG components. An icon component is ~10 lines. You need maybe 15 icons for a landing page.
• Animations → plain CSS. Scroll-blur navbars, gradient glows, an animated "typing" terminal - all doable with keyframes and transitions. No framer-motion.
• The dashboard mockup in the hero → pure CSS. Divs, borders, gradients. It looks like a product screenshot but it's ~80 lines of JSX and weighs nothing.

Result: both templates land at ~100KB first-load JS, npm install takes seconds, and there is nothing to break when Next.js 16 arrives.

Constraint 2: every piece of content in ONE typed config file

The thing I hated most about templates I've used: content is smeared across 30 components. Changing a headline means hunting through JSX. So both templates keep all content in a single file - lib/content.ts for the landing page, site.config.ts for the portfolio. Headlines, nav, pricing tiers, testimonials, project lists, even the lines that animate in the fake terminal. Components are pure renderers of that config's TypeScript type.

Two things surprised me here:

• TypeScript becomes your content linter. Forget an alt text, malform a link, give a pricing tier three features when the type expects a non-empty array - the build fails. Content mistakes surface at compile time.
• It forces better component design. When a component can only receive data shaped by the config type, you stop leaking one-off props and hardcoded strings everywhere. Every section component got simpler.

If you're building anything content-heavy - a portfolio, docs, a marketing site - I'd genuinely recommend this structure even if you never sell it.

Tailwind v4 notes (the migration was smaller than feared)

Both templates use Tailwind CSS v4. The headline change: there's no tailwind.config.js anymore - theme tokens live in CSS via @theme:

@import "tailwindcss";

@theme {
  --color-accent: oklch(0.72 0.15 260);
  --font-sans: "Inter", sans-serif;
}

Custom colors become CSS variables you can also read at runtime, @apply still works where you need it, and the content-scanning config is gone (v4 finds your classes itself). For a fresh project there's honestly less to learn than v3.

Launching with zero audience: early notes

I have no Twitter following, no newsletter, no LinkedIn presence. Things I've done in week one:

• Live demos on Vercel (free tier) - nothing converts interest like a clickable demo
• Template directories - submitted to Built At Lightspeed and Statichunt; these listings also feed AI-assistant recommendations, which is quietly becoming a real discovery channel
• Reddit - learned the hard way that a 0-day-old account posting links gets auto-filtered. Build comment karma first.

No sales yet as I write this - I'll do a follow-up post when there's real data, including what worked and what was a waste of time.

The templates

If you want to see the constraints above in practice, both demos are live:

• Nova - AI/SaaS landing page: https://nova-ai-saas-template.vercel.app
• Devfolio - developer portfolio: https://devfolio-portfolio-template.vercel.app

They're paid templates (links on the demo pages), but the ideas in this post - zero-dep icons, single-config content, @theme - are free to steal for your own projects.
