Why Use Express?
Definition
Express is the most popular Node.js framework for several reasons. It simplifies the process of creating APIs and web servers drastically compared to raw Node.js. It offers a massive ecosystem of plugins (middleware) for almost any functionality you can think of (authentication, logging, payload parsing). Because it is unopinionated, it doesn't force a specific file structure or ORM on you, giving you the ultimate freedom to architect your app as you see fit.
