Learn how the Strategy Pattern helps you write cleaner, more modular NestJS code by applying the Dependency Inversion Principle.

Instead of hardcoding logic with endless conditionals, you’ll see how to design flexible, testable strategies that keep your core business logic decoupled from implementation details.

When building APIs, especially for payments or operations that modify state, you want to avoid executing the same request multiple times if the client retries.

In this post, we’ll walk through how to bring that Stripe-style idempotency pattern into a NestJS application using an Interceptor.

Integrating authentication into a NestJS + tRPC project doesn’t have to be painful.

In this guide, we’ll walk through wiring up Better-Auth with nestjs-trpc so every API call can automatically resolve the current user from secure cookies.

Connecting to AWS RDS without SSL leaves your database traffic exposed.

This guide shows how to secure Drizzle ORM + NestJS with TLS covering Drizzle Kit setup, a production-ready DatabaseModule, and deployment tips for Docker and Kubernetes.

Supercharge your NestJS development by replacing tsc with SWC — a Rust-based TypeScript compiler that’s up to 20× faster and more memory-efficient.

This hands-on guide for experienced developers walks you through setting up a standalone NestJS app with SWC, complete with configuration tips, performance benchmarks, and Docker deployment strategies.

In this detailed performance benchmark, we put Express and Fastify head-to-head in a real-world test using Autocannon. Our results showed Fastify handling over twice the number of requests per second and delivering significantly lower latency compared to Express.

Dive into the analysis to discover why Fastify consistently outperforms Express and understand when each framework might be the right choice for your Node.js applications.
