Project structure

Learn how the supastarter codebase is structured.

supastarter uses a monorepo structure, which allows you to easily extend your project (for example with a mobile app) and share code and configs between applications.

Basic repository structure

By default the monorepo contains the following apps and packages:

TanStack Start app boundaries

The marketing site and the product app are separate TanStack Start apps. Each app has its own:

package.json
app.config.ts
route tree
tsconfig.json
global styles
Playwright config

This keeps public-site concerns and protected product concerns clearly separated.

Configuration

Configuration is scoped to the app or package that owns the behavior:

apps/marketing/config.ts – marketing app configuration
apps/saas/config.ts – SaaS app configuration
package-local config files in shared packages

Within each app, import app config through the local @config alias.

Path aliases

The alias setup is app-specific as well.

`apps/saas`
