Secure a NestJS API by implementing Helmet middleware for HTTP header protection, configuring CORS whitelisting, and using secure password hashing. You can further protect endpoints by applying guards for authentication and throttlers for rate limiting.

Structure a scalable NestJS backend by organizing code into feature modules and using event-driven patterns for loose coupling. Keeping functions short and utilizing lazy loading modules further optimizes the architecture for maintainability.

Redis caching improves NestJS performance by storing frequently accessed data in memory, which reduces database load and latency. Combining Redis with lazy loading modules optimizes application speed and minimizes resource usage.

Yes, you can use the Bun runtime with NestJS to build backend applications. Utilizing Bun runtime features alongside NestJS modules, controllers, and services helps optimize overall application performance and execution speed.

Validate and transform incoming API data in NestJS by using class-validator and class-transformer libraries. Implementing these within NestJS pipes ensures incoming payloads are strictly validated before reaching your controllers.

Use event-driven patterns in a NestJS application when you need loose coupling between different feature modules. This architecture allows components to communicate asynchronously, improving maintainability and scalability.
