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
cat package.json | grep -E "react|next|vue|nuxt|angular|express|fastify|@nestjs"

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

Framework Detection Table:

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/auth0

Windows:

scoop install auth0
# Or: choco install auth0-cli

Full installation guide: See CLI Reference

Login to Auth0

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):

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 \x3Capp-id> # Get client ID and secret

More CLI commands: See CLI Reference
