description: Use when starting Auth0 integration in any framework - detects your stack (React, Next.js, Vue, Angular, Express, React Native) and routes to correct SDK setup workflow
---

# Auth0 Quickstart

Detect your framework and get started with Auth0 authentication.

---

## Step 1: Detect Your Framework

**Run this command to identify your framework:**

```bash
# Check package.json dependencies
cat package.json | grep -E "react|next|vue|angular|express|@nestjs"

# Or check project files
ls -la | grep -E "angular.json|vue.config.js|next.config"
```

**Framework Detection Table:**

| Framework | Detection | Skill to Use |
|-----------|-----------|--------------|
| React (Vite/CRA) | `"react"` in package.json, no Next.js | `auth0-react` |
| Next.js | `"next"` in package.json | `auth0-nextjs` |
| Vue.js | `"vue"` in package.json, no Nuxt | `auth0-vue` |
| Angular | `angular.json` exists or `"@angular/core"` | `auth0-angular` |
| Express.js | `"express"` in package.json | `auth0-express` |
| React Native | `"react-native"` or `"expo"` in package.json | `auth0-react-native` |

**Don't see your framework?** See Tier 2 Frameworks below.

---

## Step 2: Auth0 Account Setup

### Install Auth0 CLI

**macOS/Linux:**
```bash
brew install auth0/auth0-cli/auth0
```

**Windows:**
```bash
scoop install auth0
# Or: choco install auth0-cli
```

**Full installation guide:** See [CLI Reference](references/cli.md#installation)

### Login to Auth0

```bash
auth0 login
```

This opens your browser to authenticate with Auth0.

---

## Step 3: Create Auth0 Application

Choose application type based on your framework:

**Single Page Applications (React, Vue, Angular):**
```bash
auth0 apps create --name "My App" --type spa \
  --callbacks "http://localhost:3000" \
  --logout-urls "http://localhost:3000"
```

**Regular Web Apps (Next.js, Express):**
```bash
auth0 apps create --name "My App" --type regular \
  --callbacks "http://localhost:3000/api/auth/callback" \
  --logout-urls "http://localhost:3000"
```

**Native Apps (React Native):**
```bash
auth0 apps create --name "My App" --type native \
  --callbacks "myapp://callback" \
  --logout-urls "myapp://logout"
```

**Get your credentials:**
```bash
auth0 apps list          # Find your app
auth0 apps show <app-id> # Get client ID and secret
```

**More CLI commands:** See [CLI Reference](references/cli.md)

---

## Step 4: Use Framework-Specific Skill

Based on your framework detection, use the appropriate skill:

### Tier 1 Frameworks (Dedicated Skills)

**Frontend:**
- **`auth0-react`** - React SPAs (Vite, Create React App)
- **`auth0-nextjs`** - Next.js (App Router and Pages Router)
- **`auth0-vue`** - Vue.js 3 applications
- **`auth0-angular`** - Angular 12+ applications

**Backend:**
- **`auth0-express`** - Express.js web applications

**Mobile:**
- **`auth0-react-native`** - React Native and Expo (iOS/Android)

### Tier 2 Frameworks (Use Auth0 Docs)

Not yet available as separate skills. Use Auth0 documentation:

**Frontend:**
- [SvelteKit](https://auth0.com/docs/quickstart/webapp/sveltekit)
- [Remix](https://auth0.com/docs/quickstart/webapp/remix)
- [Nuxt.js](https://auth0.com/docs/quickstart/webapp/nextjs)

**Backend:**
- [Flask (Python)](https://auth0.com/docs/quickstart/webapp/python)
- [FastAPI (Python)](https://auth0.com/docs/quickstart/backend/python)
- [Django (Python)](https://auth0.com/docs/quickstart/webapp/django)
- [Rails (Ruby)](https://auth0.com/docs/quickstart/webapp/rails)
- [Laravel (PHP)](https://auth0.com/docs/quickstart/webapp/laravel)

- [Android (Kotlin)](https://auth0.com/docs/quickstart/native/android)
- [Flutter](https://auth0.com/docs/quickstart/native/flutter)

---

## Migration from Other Providers

**Migrating from another auth provider?** Use the **`auth0-migration`** skill.

The migration skill covers:
- User export from Firebase, Cognito, Supabase, Clerk, etc.
- Bulk import to Auth0
- Code migration patterns (before/after examples)
- JWT validation updates
- Gradual migration strategies

---

## Reference Documentation

### Environment Variables
Framework-specific environment variable setup:

- [Next.js, Express](references/environments.md#server-side-applications)
- [React Native, Expo](references/environments.md#mobile-applications)

## Common Mistakes

| Mistake | Fix |
|---------|-----|
| Wrong application type | SPAs need "Single Page Application", server apps need "Regular Web Application", mobile needs "Native" |
| Callback URL not configured | Add your app's callback URL to Allowed Callback URLs in Auth0 Dashboard |
| Using wrong credentials | Client Secret only needed for Regular Web Apps, not SPAs |
| Hardcoding credentials in code | Always use environment variables, never commit secrets to git |
| Not testing locally first | Set up localhost URLs in Auth0 before deploying to production |
| Mixing application types | Don't use SPA SDK for server-side apps or vice versa |
