Next.js TypeScript TailwindCSS & Sass Starter

Next TypeScript TailwindCSS Sass Starter is a boilerplate for scaffolding Next.js applications with the App Router, TypeScript strict typing, TailwindCSS v4, and Sass, bundled with testing and code-quality tooling.

What is the Next TypeScript TailwindCSS Sass Starter?

This starter template scaffolds a Next.js 15.2 project that uses the App Router and React 19.1. It accepts a new project name and outputs a pre-configured codebase including TailwindCSS 4.0 with Sass 1.86, TypeScript 5.8, Vitest 3.0, ESLint 9.23, Prettier 3.5, Husky 9.1, Lint Staged 15.5, and @next/bundle-analyzer. The template is authored by MikevPeeren and published on GitHub under the MIT License.

What makes the Next TypeScript TailwindCSS Sass Starter stand out?

• App Router architecture — Uses Next.js 15.2 with the latest App Router structure, placing root layout in app/layout.tsx and homepage in app/page.tsx.
• Modern React version — Built on React 19.1, incorporating the latest features and optimizations available in the React ecosystem.
• Strict TypeScript — Fully integrated TypeScript 5.8 with strict type checking enabled.
• TailwindCSS and Sass combo — TailwindCSS v4.0 provides utility-first styling, while Sass 1.86 handles complex styling needs; global styles live in styles/globals.scss.
• Testing pre-configured — Vitest 3.0 and React Testing Library are set up with an example test in the __tests__ directory; run with yarn test.
• Code quality pipeline — ESLint 9.23 with Next.js recommended rules, Prettier 3.5 formatting, Husky 9.1 git hooks, and Lint Staged 15.5 for staged files.
• Bundle analysis — @next/bundle-analyzer is included to analyze and optimize your app's bundle size.
• One-command setup — Installable via yarn create next-app or npx create-next-app using the template's GitHub URL, with a Vercel deploy button for instant hosting.

Who should use the Next TypeScript TailwindCSS Sass Starter?

• Next.js developers who want a production-ready baseline for new projects without manually configuring TypeScript, Tailwind, Sass, and testing tools.
• Development teams that need consistent linting and formatting rules enforced before every commit through Husky and Lint Staged.
• Independent developers deploying to Vercel who want a one-click deployment path from the template repository.
• Open-source contributors who need a minimal, MIT-licensed starting point with an included test runner.

What can you do with the Next TypeScript TailwindCSS Sass Starter?

• Scaffold a new app: Run the create-next-app command with the template URL to generate a project, then start the development server with yarn dev.
• Write and run tests: Use the pre-installed Vitest and React Testing Library to add and execute test files from the __tests__ directory.
• Enforce code quality: Run yarn lint and yarn format to check and format code, with Husky and Lint Staged running them automatically on staged commits.
• Deploy to Vercel: Click the "Deploy with Vercel" button to create a new Vercel project from the template without leaving the browser.

How does the Next TypeScript TailwindCSS Sass Starter work?

Getting started takes two commands: copy the template with yarn create next-app my-app -e https://github.com/MikevPeeren/next-typescript-tailwindcss-sass-starter (or the npx equivalent), then navigate into the folder and run yarn dev. The development server starts at http://localhost:3000 with hot reloading. The project structure separates app/ for router files, styles/ for global SCSS, and __tests__/ for test files.
