Always use pnpm instead of npm for all package management tasks:

• Use pnpm install instead of npm install
• Use pnpm add <package> instead of npm install <package>
• Use pnpm add -D <package> instead of npm install --save-dev <package>
• Use pnpm remove <package> instead of npm uninstall <package>
• Use pnpm run <script> instead of npm run <script>
• Use pnpm <command> for any other npm commands
• Use pnpm dlx <command> instead of npx <command>
• Use pnpm create <template> instead of npm create <template>

When running scripts from package.json, always use:

• pnpm dev for development server
• pnpm build for production build
• pnpm run test for running tests
• pnpm lint for linting
• pnpm typecheck for type checking
• pnpm format for code formatting

For database-related tasks:

• pnpm db.generate to generate database migrations
• pnpm db.local.migrate to apply local migrations
• pnpm db.prod.migrate to apply production migrations

Never use npm, yarn, or any other package manager in this project. All package operations should be performed with pnpm.

This project uses TanStack Start. The root route is at src/route/__root.tsx.

Here's the tech stack:

• framework: TanStack Start (@tanstack/start) with react
• router: TanStack Router (@tanstack/router)
• ui: shadcn/ui
• css: tailwindcss (v4)

We use vitest for the tests.

All tests are in __test__/.

• NEVER run the dev server (e.g.: pnpm dev)!
• always ensure no formatting/linting issues exist in your code
  • this command automatically fixes these issues where possible: pnpm check --fix
• NEVER deploy anything (e.g. with pnpm preview.deploy, or pnpm run deploy)

• Prefer functions over arrow functions for React components and everything else
• Prefer type-s over interface-s
