Express

Express is a free, open-source backend framework for JavaScript applications. It supports server-side rendering and is listed for Linux, macOS, and Windows. Its deployment target is self-hosted, so the application environment is not provided as a hosted target in the framework listing. Express does not include an ORM or built-in authentication. Those omissions are relevant when deciding whether its stated framework capabilities fit a project: database mapping and authentication are not included among the listed built-in features. The scope described here is backend development in JavaScript, server-side rendering, and self-hosted deployment. Teams can use it without a paid plan, and can plan around the listed operating systems. Developers choosing Express should account for arranging self-hosting and for the absence of included ORM and authentication capabilities. The framework’s listed details give a concise basis for determining whether those requirements match an application’s needs.

It suits developers seeking a free, open-source JavaScript backend framework with server-side rendering. Teams must be prepared to self-host and address ORM and authentication needs separately.
