[ramya18101]

🔧 Changes

Added a new auth0 quickstarts setup command that automates the creation of Auth0 applications and environment configuration for quickstart projects.

New Command:

• auth0 quickstarts setup --type <type> (alias: auth0 qs setup)

Command Behavior:

1. Creates an Auth0 application based on the specified type
2. Generates a .env file with appropriate environment variables

Supported Application Types:

Type	Auth0 App Type	Port	Output File	Variables
vite	SPA	5173	.env	VITE_AUTH0_DOMAIN, VITE_AUTH0_CLIENT_ID
nextjs	Regular Web App	3000	.env.local	AUTH0_DOMAIN, AUTH0_CLIENT_ID, AUTH0_CLIENT_SECRET, AUTH0_SECRET, APP_BASE_URL

Flags:

• --type, -t: Application type (required) - vite or nextjs
• --name, -n: Application name (default: "My App")
• --port, -p: Port number (default: 5173 for vite, 3000 for nextjs)

General Feedback:

• Add validation checks for type param. It currently accepts any value and fails during app creation.
• Add a confirmation before overwriting existing .env files. We don't want developers to accidentally lose their secrets due to an overwrite.
• Add a validation check for port number input. Ports can only be between 1024 and 65535
• Nitpick: Enhance the success message to show a more elegant text and next steps to run the app
