Adding Auth0 to your Create.xyz app? Let us review it.
Expert review for Auth0 integrations built with Create.xyz. We fix Create.xyz-generated Auth0 code for security, error handling & production readiness. From $19.
Common Create.xyz issues affecting integrations
No authentication — all generated apps are fully public with no user accounts
Create.xyz generates functional applications without any authentication system. Every page, API endpoint, and data resource is accessible to anyone with the URL, making it unsuitable for any application that handles user-specific or private data.
Hardcoded data and mock API responses replace real database or API integration
Generated applications use static JavaScript arrays or hardcoded JSON as data sources. There is no real database integration — data does not persist between sessions, is visible in source code, and resets on every page reload.
No input validation or sanitization on generated form and API handlers
Form submissions and API routes in Create.xyz-generated code process user input directly without validation, type checking, or sanitization, making them vulnerable to injection attacks and malformed data that breaks the application.
Auth0 issues we find in Create.xyz apps
Using deprecated auth0-js instead of @auth0/auth0-spa-js
AI tools generate code with the legacy auth0-js library using implicit grant flow, which is insecure and deprecated in favor of Authorization Code with PKCE.
Storing tokens in localStorage
Generated code saves access and refresh tokens in localStorage, making them vulnerable to XSS attacks. Tokens should use in-memory storage or secure HTTP-only cookies.
Callback and logout URLs not configured for all environments
AI tools hardcode localhost callback URLs and forget to configure production URLs in the Auth0 dashboard, causing redirect failures on deployment.
