Structure a Node.js backend by separating directory structure into controller and service patterns, using Prisma for database access. This approach ensures consistency and maintainability across your Express application routes.

Implement JWT authentication in Express by validating tokens and enforcing mandatory permission checks via database lookups. Using a helper like getPerms ensures secure login flows and proper authorization before route access.

Integrate external APIs like Conta Azul in Node.js by using internal wrappers for token refresh and secure data handling. This ensures reliable authentication and consistent communication with external services.

Yes, you can use Prisma for database access within an Express controller service architecture. The service layer handles Prisma queries, while controllers manage HTTP requests, maintaining a clean separation of concerns.

You need to refresh external API tokens in Node.js when handling integrations like Conta Azul. Implement internal wrappers to automatically manage token refresh logic and ensure secure data handling during API communication.
