# Next.js Starter Template

A modern Next.js starter template with App Router, TypeScript, Tailwind CSS v4, shadcn/ui, and a comprehensive linting setup.

## Features

- **Next.js 16** with App Router and Server Components
- **TypeScript** in strict mode
- **Tailwind CSS v4** with shadcn/ui components
- **Atomic Design** component architecture (atoms, molecules, organisms)
- **next-intl** i18n with base+overlay locale model and YAML-authored dictionaries
- **Biome** for linting, formatting, and import sorting (one tool, fast)
- **Husky & lint-staged** for pre-commit code quality checks
- **Commitlint** for conventional commit messages
- **Bun** as the package manager

## Getting Started

### Prerequisites

- Node.js (v24 or later)
- [Bun](https://bun.sh/) (recommended) or any package manager (`pnpm`, `yarn`, `npm`)

### Installation

```bash
git clone https://github.com/MKSinghDev/nextjs-starter.git
cd nextjs-starter
bun install
```

### Development

```bash
bun dev
```

Open [http://localhost:3000](http://localhost:3000) in your browser.

| `test:run`       | Run unit/component tests once                                    |
| `test:coverage`  | Run unit/component tests with coverage thresholds                |
| `test:governance`| Assert every authored component has a mirror test in `tests/`    |
| `test:e2e`       | Run Playwright end-to-end tests                                  |

## Internationalization

- URL locales are **regional variants only** (`en-US`, `en-GB`, `es-ES`, `es-MX`, `hi-IN`). Listed in `src/i18n/routing.ts`. Default locale serves on clean paths (`/`, `/users`) via `localePrefix: 'as-needed'`; non-default keeps the prefix (`/es-MX`, `/es-MX/users`)
- Each regional variant maps to a **base locale** (`en`, `es`, `hi`) via `baseOf` in `src/i18n/bases.ts`. Bases are never URL-addressable
- Dictionaries authored in **YAML** under `locales/<locale>/*.yaml` (committed). Compiled to `messages/<locale>/*.json` + per-locale `index.ts` by `scripts/gen-messages.ts` (`messages/` is fully gitignored; regenerated on every build / dev / check-types)
- Runtime deep-merges base dict + regional overlay per request. Overlays hold only the keys that differ
- Keys are fully type-checked — `useTranslations('home')` and `t('title')` autocomplete against the `en` reference shape

Adding or editing translations, and the full locale-addition recipe, lives in [STANDARDS.md](./STANDARDS.md#internationalization-i18n).

**Don't need i18n?** Ask Claude to _"remove i18n"_ and it runs the `remove-i18n` skill at [`.claude/skills/remove-i18n/SKILL.md`](./.claude/skills/remove-i18n/SKILL.md) — that same file also serves as the manual removal checklist if you'd rather strip it by hand.

## Standards

See [STANDARDS.md](./STANDARDS.md) for the full coding standards covering naming conventions, component architecture, styling, and more, and [TESTING.md](./TESTING.md) for the testing standards (unit/component + E2E).

## Claude Code Skills

This project recommends a set of Claude Code skills that extend the AI agent with project-specific tooling (e.g. shadcn component registry access). See [SKILLS.md](./SKILLS.md) for the list and install commands.
