nest

Nest is a framework for building efficient, scalable Node.js server-side applications. It uses modern JavaScript and is built with TypeScript while preserving compatibility with pure JavaScript. The framework combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming). Under the hood, Nest makes use of Express by default, but also provides compatibility with a wide range of other libraries, such as Fastify, allowing for easy use of third-party plugins. The project aims to provide an application architecture out of the box that supports highly testable, scalable, loosely coupled, and easily maintainable applications. Its architecture is heavily inspired by Angular. The README links to official documentation at docs.nestjs.com and mentions localized guides in Chinese, Korean, and Japanese. Community support is handled through the official Discord channel, while the GitHub issue tracker is reserved exclusively for bug reports and feature requests. Nest is MIT-licensed and lists principal, gold, silver, and general sponsors, along with Open Collective backers.
