@adonisjs/core is a powerful web framework for Node.js that is designed to help developers build scalable and maintainable web applications with ease. It provides a rich set of features, including an ORM, routing, middleware support, and an intuitive syntax, making it a great choice for building full-fledged applications quickly. AdonisJS follows the MVC (Model-View-Controller) architecture, which encourages organized code and separation of concerns. Its built-in features and conventions help streamline the development process, allowing developers to focus on building their applications rather than dealing with boilerplate code.

While AdonisJS offers a comprehensive solution for web development, there are several alternatives in the Node.js ecosystem that cater to different needs and preferences:

• express is one of the most popular web frameworks for Node.js. It is known for its simplicity and flexibility, allowing developers to create web applications and APIs quickly. Express provides a minimalistic approach, giving developers the freedom to structure their applications as they see fit. Its extensive middleware ecosystem allows for easy integration of various functionalities, making it a versatile choice for many projects.

• koa is another web framework for Node.js that is designed to be lightweight and modular. Created by the same team behind Express, Koa aims to provide a more expressive and robust foundation for web applications. It uses async/await syntax, making it easier to handle asynchronous operations and improve code readability. Koa is ideal for developers who prefer a more modern approach to building web applications and want to have more control over the middleware stack.

• sails is a full-featured MVC framework for Node.js that is built on top of Express. It is designed for building data-driven applications and APIs, providing a powerful ORM called Waterline for database interactions. Sails comes with built-in support for WebSockets, making it a great choice for real-time applications. If you're looking for a framework that combines the best of Express with additional features for building data-centric applications, Sails is worth considering.
