"Why NestJS is the Better Choice for Building Node.js Applications: Exploring the Benefits Over Express.js"​? ›

Strongly Typed Language: NestJS is built on top of TypeScript, a strongly-typed superset of JavaScript. This provides developers with a powerful set of tools to write cleaner, more concise code, and catch errors before they occur. It also makes code easier to understand and maintain over time.

NestJS provides multiple features like dependency injection, support for various data stores, GraphQL support, and more. So, to sum up, NodeJS enables one to build server-side applications using JavaScript while NestJS offers a standardized and scalable structure to build these applications.

Developers may choose Nestjs over Expressjs for its built-in support for TypeScript, dependency injection, and modular architecture, making it suitable for building scalable and large-scale applications.

It provides a robust framework for developing scalable and maintainable backend systems using Node. js. Nest. js is often chosen when there is a need for a modular architecture, dependency injection, and powerful features for handling HTTP requests, data processing, and business logic.

Node JS is a fast JavaScript runtime environment that we use to build server-side applications, but it does not know how to perform serving files, handling requests, and handling HTTP methods, so this is where express js comes in.

NestJS provides middleware and pipes for intercepting and modifying incoming requests and outgoing responses. You can use RxJS operators to handle asynchronous operations within middleware or pipes. For example, you can use the map operator to transform data or catchError operator to handle errors.

NestJS has first-class support for GraphQL, enabling developers to create powerful APIs with ease. The @nestjs/graphql package provides a set of decorators and tools to seamlessly integrate GraphQL into NestJS applications.

This flexibility makes NestJS a great choice for many developers! TypeScript Support: Native support for TypeScript, enhancing developer productivity and reducing bugs. Modular Architecture: Encourages the use of modules, making it easy to manage and scale applications.

Next. js benefits from the larger React ecosystem, while Nest. js has a dedicated community focused on server-side development. Ultimately, both frameworks provide sufficient community support and resources to help developers build robust applications.

Fastify provides a good alternative framework for Nest because it solves design issues in a similar manner to Express. However, fastify is much faster than Express, achieving almost two times better benchmarks results.

Why learn NestJS? ›

NestJS is a framework for building server-side applications using Node. js. Think of it like a toolkit that helps you create a powerful and efficient backend. It's especially great if you're working on something big and want your code to stay organized and easy to manage.

Dropping support for Node.

As of NestJS 10, we no longer support Node. js v12, as v12 went EOL on April 30, 2022. This means that NestJS 10 requires Node. js v16 or higher.

NestJS, on the other hand, is a framework for building efficient, reliable, and scalable server-side applications. It is built on top of Express (but can also work with Fastify) and adds an extra layer of abstraction with its out-of-the-box application architecture.

Advantages of Express JS: Decoding the Enigma

Express. js is nothing but an open-source server-side as well as a mobile API application framework meant to handle Node. js. This has the ability to simplify all the development processes in the way by which we offer more extra features, tools, plugins, and packages.

Fast and Responsive: Despite its single-threaded nature, Node. js excels at multitasking, efficiently managing tasks while awaiting others to complete them. This results in websites built with Node. js feeling exceptionally fast and responsive.

Go, Rust, Scala, and ASP.NET are best for heavy computations, and Ruby and Python are scripting languages that can build fast and scalable web applications. You may still choose to work with Node. js, but the constraints of your unique project or organization might make one of these other options a better choice.

Single-threaded nature:

This design choice can limit its performance in certain scenarios, especially when dealing with CPU-intensive tasks. Although Node. js uses an event-driven, non-blocking I/O model to handle concurrent requests efficiently, it is not well-suited for CPU-bound operations.
