Next.js TypeScript Starter Kit

Next.js TypeScript Starter Kit is a boilerplate repository that scaffolds a Next.js 8.1 application with TypeScript, styled-jsx, module CSS, and a preconfigured testing and SEO stack.

What is the Next.js TypeScript Starter Kit?

The Next.js TypeScript Starter Kit is a GitHub-hosted boilerplate created by deptno that serves as a starting point for building Next.js applications in TypeScript. Running on Node.js with yarn as the package manager, it accepts a fresh clone of the repository and produces a working Next.js 8.1 project that can be run in development, built for production, or exported as static HTML. It comes prewired with TypeScript type checking, styled-jsx for scoped styles, CSS modules processed by PostCSS with cssnext, nested, and import plugins, and a Jest & Enzyme test environment that understands CSS modules.

Key Features

• TypeScript — The entire starter is written in TypeScript, including the configuration constants in src/constants/env.ts, eliminating the need to add type support yourself.
• styled-jsx — Supports both local-scoped styles inside components and global styles for layout elements, using Next.js's built-in CSS-in-JS solution.
• Module CSS with PostCSS — CSS modules are enabled through PostCSS plugins: cssnext for future CSS syntax, nested for nested selectors, and import to bundle external stylesheets.
• SEO & analytics — Includes a central src/constants/env.ts file where you set SITE_NAME, SITE_TITLE, SITE_DESCRIPTION, SITE_IMAGE, GA_TRACKING_ID, FB_TRACKING_ID, and SENTRY_TRACKING_ID; each analytics library is only loaded when its ID is provided.
• Jest & Enzyme — Preconfigured test runner and component-testing utilities that support CSS modules, with commands for watch mode and coverage reports.
• Font Awesome 5 from CDN — Loads Font Awesome icon styles from a CDN, so no local font asset management is needed.
• Static HTML export — The yarn export command generates a .out directory with static HTML for hosting anywhere without a Node server.

Who is it for?

The kit targets developers who want a ready-made Next.js + TypeScript setup without spending time on configuration. It suits "Next.js developers who want a preconfigured TypeScript environment," "SEO-focused projects that need Open Graph tags and analytics integration," "teams that rely on Jest and Enzyme for component testing," and "developers who prefer CSS modules and styled-jsx over a CSS framework." Each of these roles can clone the repo, run yarn, and begin coding immediately.

What can you do with the Next.js TypeScript Starter Kit?

• Next.js developers: Clone the repository, remove the .git directory with rm -r .git, run yarn, and start a hot-reloading dev server with yarn start:dev for immediate development.
• SEO-focused projects: Fill in the site and tracking constants in src/constants/env.ts to generate Open Graph and Twitter meta tags plus Google Analytics and Facebook Pixel loading, with Sentry optional.
• Test-driven teams: Run yarn test, yarn test:watch, or yarn test:coverage to execute the Jest & Enzyme suite, which is already configured to handle CSS modules.
• Static site publishers: Use yarn build && yarn export to produce a .out folder of static HTML files that can be deployed to any static hosting service.

How does the Next.js TypeScript Starter Kit work?

The setup process is copy-and-run rather than a CLI wizard. You clone the repository, delete the existing Git history, install dependencies with yarn, then use the npm scripts provided. The start:dev script launches the development server, test runs the Jest suite, build compiles a production build into .next, and start serves that build. The export script turns the production build into static HTML, and test:coverage generates a coverage report.
