Philosophy

The Express philosophy is to provide small, robust tooling for HTTP servers, making it a great solution for single page applications, web sites, hybrids, or public HTTP APIs.

Express does not force you to use any specific header middleware. With support for many user cases, you can quickly craft your perfect framework with the Express-Header middleware.
