Auth0 Quickstart
Detect your framework and get started with Auth0 authentication.
Step 1: Detect Your Framework
Run this command to identify your framework:
# Check package.json dependencies (Node.js projects)
cat package.json | grep -E "react|next|vue|nuxt|angular|express|fastify|@nestjs|expo"
# Or check project files
ls -la | grep -E "angular.json|vue.config.js|next.config|app.json|Package.swift|build.gradle"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 |
| Nuxt | "nuxt" in package.json | auth0-nuxt |
| Angular | angular.json exists or "@angular/core" | auth0-angular |
| Express.js | "express" in package.json | auth0-express |
| Fastify (web app) | "fastify" in package.json, has @fastify/view | auth0-fastify |
| Fastify (API) | "fastify" in package.json, no view engine | auth0-fastify-api |
| React Native | "react-native" or "expo" in package.json | auth0-react-native |
| Flask | "flask" in requirements.txt, Pipfile, or pyproject.toml | auth0-flask |
| Node.js API | "express-oauth2-jwt-bearer" in package.json | express-oauth2-jwt-bearer |
Don't see your framework? See Tier 2 Frameworks below.
Step 2: Auth0 Account Setup
Install Auth0 CLI
macOS/Linux:
brew install auth0/auth0-cli/auth0Windows:
scoop install auth0
# Or: choco install auth0-cliFull installation guide: See CLI Reference
Login to Auth0
auth0 loginThis 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):
auth0 apps create --name "My App" --type spa \
--callbacks "http://localhost:3000" \
--logout-urls "http://localhost:3000" \
--metadata "created_by=agent_skills"Regular Web Apps (Next.js, Nuxt, Express, Fastify):
auth0 apps create --name "My App" --type regular \
--callbacks "http://localhost:3000/api/auth/callback" \
--logout-urls "http://localhost:3000" \
--metadata "created_by=agent_skills"Native Apps (React Native):
auth0 apps create --name "My App" --type native \
--callbacks "myapp://callback" \
--logout-urls "myapp://logout" \
--metadata "created_by=agent_skills"Get your credentials:
auth0 apps list # Find your app
auth0 apps show <app-id> # Get client ID and secretMore CLI commands: See CLI Reference
Step 4: Use Framework-Specific Skill
Based on your framework detection, use the appropriate skill:

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

CLI Commands
Complete Auth0 CLI reference:
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 |
