Top Node.js Backend Frameworks in 2025

Introduction

Node.js boasts some of the most trusted backend frameworks on the market as of 2024. The frameworks allow developers to build and deploy server-side applications easily.

A Node.js backend framework is a set of tools, libraries, and conventions built on the Node.js runtime environment.

The frameworks provide a higher-level abstraction and a set of ready-made components and features.

Node.js backend frameworks allow developers to focus on the core functionality of their applications rather than the low-level details of server-side programming.

A Node.js backend framework typically includes features such as:

• Routing
• Middleware
• Database
• Integration
• Authentication
• Error handling

The frameworks can support various programming paradigms, including procedural, object-oriented, and functional programming.

Some of the benefits of using a Node.js backend framework include:

• Increased productivity
• Faster development cycles

• Improved code quality
• Easy access and use of databases such as MongoDB object databases.
• Better scalability and maintainability of the application

The above is only the tip of the iceberg on why you should work with Node.js backend frameworks. Keep reading for detailed descriptions of the best frameworks!

What is Node.js?

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code via the JavaScript execution engine. It does this outside of a web browser.

It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient and allows for scalable and high-performance network applications.

Node.js was created by Ryan Dahl in 2009 and has since gained popularity for its ability to handle large amounts of I/O operations.

Some I/O operations handled by Node.js include data streaming and real-time communication. This makes it suitable for building server-side applications and APIs.

What is Node.js used for?

The cross-platform runtime environment is a developer’s favorite framework for a number of reasons which include:

Building Scalable Network Applications

Node.js can build scalable and high-performance web applications using popular web frameworks such as Express, Koa, and Hapi.

Developing Server-Side APIs

Node.js can create RESTful APIs and microservices using tools such as Express and LoopBack.

Real-Time Communication on Web and Mobile Applications

Node.js can build real-time applications, such as chat and online gaming platforms, using tools like Socket.io and WebSockets.

Multi-Threaded Event Loop

Since Node.js is a JavaScript runtime environment, it runs JavaScript codes on a single-threaded event loop.

However, Node.js is multithreaded with hidden threads in the libuv platform abstraction layer.

Developers can use Node.js to make simultaneous connections and concurrent requests in the event loop.

Data Streaming

Node.js can handle large amounts of data streaming, such as video and audio streaming, using tools such as Stream API.

Command-Line Tools

Node.js can be used to build command-line tools and scripts, using tools such as Commander and Inquirer.

CallBack Function

Callbacks in the open-source, cross-platform framework, Node.js, ensure that the functions only run after task completion.

The callback function then develops a JavaScript code keeping them from errors.

Sails.js

Sails.js is an MVC (Model-View-Controller) framework built on top of Node.js, designed to facilitate the rapid development of custom, enterprise-grade Node.js applications. As an extension of the capabilities provided by Node.js, Sails.js inherits Node’s non-blocking, event-driven architecture, making it an excellent choice for developing data-intensive, real-time applications. Here are some key points about Sails.js that you might find valuable for your post:

• Rapid Development: Sails.js emphasizes convention over configuration, allowing developers to quickly scaffold applications and focus on building features. This is particularly beneficial for projects requiring a speedy development cycle without sacrificing quality or scalability.

• Real-Time Capabilities: Leveraging Socket.io, Sails.js offers built-in support for WebSockets, enabling real-time communication between clients and servers. This feature is a boon for applications requiring live updates, such as chat applications, live notifications, and collaborative platforms.

• Data-Driven APIs: At its core, Sails.js is designed to make it straightforward to build RESTful APIs. The framework automatically generates REST APIs for your models, drastically reducing the amount of boilerplate code developers need to write for data operations.

• Wide Database Support: With its waterline ORM, Sails.js offers a unified data access layer, abstracting the database interaction and providing a simple data access syntax that works across different database systems, including MongoDB, PostgreSQL, MySQL, and more.

• Extensible through Plugins: Known as “hooks,” the plugin architecture of Sails.js allows developers to extend or customize the framework’s core functionality. This flexibility means that applications can be tailored to specific requirements through the addition of custom hooks or leveraging existing ones from the ecosystem.

• Front-end Agnostic: While Sails.js provides a backend solution, it remains agnostic regarding the front-end technology. Developers have the freedom to integrate any front-end framework (React, Angular, Vue.js) or library they prefer, making Sails.js a versatile choice for full-stack development.

Incorporating Sails.js into your Node.js-based projects not only enhances the backend with robust features for web and API development but also streamlines the development process with its convention-based architecture. Whether you’re building a complex enterprise application or a simple web app, Sails.js provides the tools necessary to create efficient, scalable solutions that leverage the full power of Node.js.
