@loopback/core is a powerful and extensible Node.js framework for building scalable and maintainable applications. It provides a set of essential building blocks and abstractions for creating APIs, microservices, and server-side applications. With @loopback/core, you can easily define models, repositories, controllers, and routes using decorators and TypeScript decorators.
Sails is a powerful and flexible MVC framework for building Node.js applications. It provides a convention-over-configuration approach, making it easy to create scalable and maintainable web applications. Sails follows the Model-View-Controller (MVC) pattern, allowing you to separate your application's logic into distinct components.
Both @loopback/core and Sails are popular npm packages in the Node.js community. However, Sails has been around for longer and has a larger user base and community support compared to @loopback/core.
@loopback/core is a part of the LoopBack framework, which is a highly extensible and scalable framework for building APIs and microservices. It follows a modular and dependency injection-based architecture, allowing developers to easily customize and extend the functionality. Sails, on the other hand, is a full-featured MVC framework that follows the convention-over-configuration principle. It provides a more opinionated architecture out-of-the-box.
@loopback/core is designed to be highly scalable and supports building large-scale applications with ease. It provides features like dependency injection, middleware support, and built-in support for clustering. Sails is also scalable, but it may require additional configuration and optimization for handling high traffic and large-scale applications.
@loopback/core provides a robust and well-documented API, making it easier for developers to understand and work with the framework. It also has good TypeScript support, which helps in building type-safe applications. Sails also has a good developer experience with a comprehensive documentation and a large number of community-contributed plugins.
