RabbitMQ is a powerful and flexible messaging broker that enables communication between services in a decoupled manner. In a microservices architecture, RabbitMQ plays a vital role in ensuring that different services can interact and exchange data asynchronously. NestJS, a progressive Node.js framework, provides excellent support for building scalable microservices, including RabbitMQ integration.

In this article, we’ll walk through how to integrate RabbitMQ in a NestJS application, including both sending and receiving messages. We’ll also explore a real-world example where RabbitMQ is used to process tasks asynchronously.

When building APIs, managing different versions is critical for backward compatibility and feature updates. NestJS provides built-in support for API versioning, allowing developers to handle multiple versions of APIs gracefully.

This article explores API versioning in NestJS, its types, and how to implement them with examples.

Why API Versioning?​

API versioning helps manage changes in your application without breaking functionality for existing clients. It ensures:

• Smooth transitions between versions.
• Backward compatibility for older API clients.
• Clear separation of new features or deprecations.

When working with NestJS and Mongoose, one commonly used feature is the timestamps option in schemas, which automatically manages createdAt and updatedAt fields. By default, Mongoose uses camelCase (createdAt, updatedAt) for these fields. However, you might need to follow a different naming convention, such as snake_case (created_at, updated_at), to align with your database's naming standards or project guidelines.

In this article, we'll explore how to customize these keys in a NestJS Mongoose schema.

In this article, we will explore how to implement a custom response interceptor in a NestJS application to format all API responses in a standardized structure. This is particularly useful for maintaining consistency across APIs, making it easier for front-end developers and other consumers of the API to parse and understand the responses.

What Is an Interceptor in NestJS?​

In NestJS, interceptors are a powerful feature that allow you to:

1. Transform data before sending it to the client.
2. Manipulate the request/response.
3. Perform logging, analytics, or caching.
4. Add custom headers or structure the API response consistently.

Interceptors are executed before and/or after the route handler, giving you the flexibility to transform the incoming request or the outgoing response.

Learn how to integrate Firestore with NestJS in this step-by-step guide. This example demonstrates setting up Firebase Admin SDK, creating services for CRUD operations, and exposing RESTful APIs to interact with Firestore in your NestJS application.

To integrate NestJS with Google Firestore, you will need to follow a few steps to set up and interact with Firestore within a NestJS application.

Here’s a simple example that demonstrates how to set up Firestore with NestJS, including the installation and usage of required dependencies, as well as an example service and controller to interact with Firestore.

NestJS is a progressive framework for building scalable server-side applications. To enhance security, optimize performance, and streamline functionality, various middleware and libraries are integrated into NestJS projects. This guide explores essential tools and features such as CORS, Swagger, Mongoose, Rate Limiting, CSP, Helmet, Custom Logging, PM2 Logging, and Environment Variables Handling with .env, complete with examples.

When deciding between Prisma and Mongoose for a MongoDB-based application, there are several factors to consider. Both are powerful tools, but they are designed with different paradigms and use cases in mind. Below is a breakdown to help you understand when you might prefer one over the other.

What is NestJS?​

NestJS is an ever-evolving Node.js (strong essential design on which greater things can be worked) for building (delivering a ton with very little waste), dependable, and (ready to be made greater or more modest) server-side PC programs. It is worked with and completely upholds TypeScript, while as yet permitting engineers to compose code altogether/absolutely/with nothing else blended in JavaScript. NestJS is intensely given good thoughts from Thin (so you can see bones)/having points and exploits its particular (connected with the wonderful plan and development of structures, and so on) to support the advancement of reusable, testable, and viable parts/pieces.
