These are the most used Node.js frameworks.

Nest.js – This powerful Node.js backend framework is suitable for building enterprise-level projects. It has a large number of libraries that implement Typescript, Model-View-Presenter (MVP), and integrated Object-Oriented-Programming (OOP), Function-Point (FP), and Functional-Reactive-Programming (FRP) principles (FRP).

Express.js is a lightweight framework that uses minimal design and has a lot of HTTP helpers. It’s ideal for developers who don’t require a long and expensive development process. It is perfect for creating APIs, mobile apps, and web applications. is easy to use across many platforms because of its user-friendliness. It is focused on bi-directional real-time connectivity. It supports multiplexing, binary, and reconnection.

Meteor.js is a web-based platform that allows real-time functionality, dynamic imports, frontend-to-backend connectivity, API protection, and front-end-backend connectivity.

Koa.js: This uses asynchronous methods to reduce error handling and increase the application’s performance. is a tool that allows developers to create APIs quickly. It offers a variety of features that simplify the process. Supported are ad-hoc queries as well as storage services. It supports many REST services, as well as well-known databases. It’s fine that you discuss the budget of several firms and request estimates from several best outsourced Node.js developers.
