create-nosa

Scaffolding for nosa projects.

create-nosa is a Bun first project generator. It runs an interactive setup flow, copies a selected static template folder, installs dependencies with Bun when the selected template is complete, initializes git, and prints the next commands.

Requirements

• Bun >=1.3.0
• Git

Nix users can optionally run nix develop to enter a shell with Bun and Git.

Usage

With Bun:

bun create nosa@latest

You can also run the package directly:

bunx --bun create-nosa@latest

Other package runners can invoke the CLI too:

npx create nosa
yarn dlx create nosa
pnpm dlx create nosa

The generated templates include bunfig.toml and use Bun by default. A fresh bun.lock is generated during bun install.

Interactive Flow

? Project name
  my-nosa-app

? Select a template
  Start

? Select codebase structure
  Simple
  Vertical

? Select add-ons
  [ ] shadcn/ui
  [ ] Drizzle + PostgreSQL
  [ ] Better Auth
  [ ] Google OAuth

Non-interactive Usage

All prompts can be skipped by passing flags:

bun create nosa --name my-app --structure simple --addons shadcn,drizzle

Flag	Values	Description
-n, --name	any folder name	Project name
-t, --template	start	Template
-s, --structure	simple, vertical	Codebase structure
-a, --addons	shadcn, drizzle, betterauth, google-oauth (comma-separated)	Add-ons
-h, --help		Show help

Any omitted flag falls through to the interactive prompt for that field.

Templates

Templates live in src/templates. Each supported combination is intended to be a complete static folder that the CLI can copy directly.

Current option status:

• Template: Start
• Structure: Simple and Vertical
• Add-ons: shadcn/ui (includes TanStack Form), Drizzle + PostgreSQL, Better Auth (auto-includes Drizzle), Google OAuth (auto-includes Better Auth and Drizzle), and their supported combinations

Vertical Philosophy

Code is grouped by domain rather than by technical layer. Each feature lives in its own directory so you can own it, evolve it, and eventually throw it away.

src/
  auth/             # Authentication domain
  billing/          # Billing domain
  plans/            # Plan management domain
  teams/            # Teams and collaboration domain
  data/             # Database access
  design-system/    # Shared UI primitives
  errors/           # App-level error normalization and boundaries
  routes/           # Route definitions (required by TanStack Router)
  router.tsx        # Router configuration
  styles.css        # Global styles

Each directory owns its components, hooks, server functions, types, and schemas. Add new verticals by creating a directory at src/. Remove a feature by deleting its directory.

data/, design-system/, and errors/ are app-level verticals: shared infrastructure that can grow with the app, not feature verticals like auth/, billing/, or teams/.

Simple templates keep shared error normalization in src/errors.ts. Vertical templates use src/errors/ because error handling can grow into reusable boundary UI, typed app errors, and reporting while staying separate from feature domains.

Base

Lean TanStack Start template which includes:

• Framework: TanStack Start with React 19
• Styling: Tailwind CSS v4
• Tooling: Oxc with oxlint and oxfmt
• Git Hooks: simple-git-hooks and nano-staged

Add-ons

shadcn/ui adds:

• Components: generated Button, Sonner, and form field components
• Forms: TanStack Form with Zod validation
• Utilities: cn() with clsx and tailwind-merge
• Theme: shadcn Tailwind CSS variables and Roboto font setup

TanStack Form is included when shadcn/ui is selected; it is not a separate add-on.

Drizzle + PostgreSQL adds:

• ORM: Drizzle ORM configured for PostgreSQL
• Driver: pg through drizzle-orm/node-postgres
• Schema: starter users table in src/db/schema.ts
• Commands: db:generate, db:migrate, db:push, and db:studio

Better Auth adds:

• Auth: Better Auth with database-backed session handling and no sign-in method enabled by default
• Integration: TanStack Start handler at src/routes/api/auth/$.ts
• Server functions: session helpers in src/lib/auth.functions.ts
• Drizzle schema: auto-generated auth tables in src/db/auth.schema.ts
• Dependencies: better-auth with tanstackStartCookies plugin
