Express/Node introduction
While Express itself is fairly minimalist, developers have created compatible middleware packages
to address almost any web development problem. There are libraries to work with cookies, sessions,
user logins, URL parameters, POST data, security headers, and many more...
Express.js
Express.js, or simply Express, is a back end web application framework for Node.js, released as
free and open-source software under the MIT License. It is designed for building web applications
and APIs. It has been called the de facto standard server framework for Node.js.
The original author, TJ Holowaychuk, described it as a Sinatra-inspired server, meaning that it
is relatively minimal with many features available as plugins. Express is the back-end component
of popular development stacks like the MEAN, MERN or MEVN stack, together with the MongoDB
database software and a JavaScript front-end framework or library.
Express.js was founded by TJ Holowaychuk. The first release, according to Express.js's GitHub
repository, was on the 22nd of May, 2010. Version 0.12.
In June 2014, rights to manage the project were acquired by StrongLoop. StrongLoop was acquired
by IBM in September 2015; in January 2016, IBM announced that it would place Express.js under
the stewardship of the Node.js Foundation incubator.
Express.js is used by Fox Sports, PayPal, Uber and IBM.

How to setup Express.js in Node.js
Express.js is the most popular choice when it comes to building web applications with Node.js.
However, when saying web applications with Node.js, it's often not for anything visible in the
browser (excluding server-side rendering of a frontend application). Instead, Express.js, a web
application framework for Node.js, enables you to build server applications in Node.js. As a
backend application, it is the glue between your frontend application and a potential database
or other data sources (e.g. REST APIs, GraphQL APIs). Just to give you an idea, the following
is a list of tech stacks to build client-server architectures...
Going out to eat and understanding the basics of Express.js
If you have ever visited a sit-down restaurant, then you can understand the basics of Express.
But if you are just starting to build your first Node.js back end…you might be in for a bumpy
ride.
Yes — it is certainly easier to learn Node if you have past experience with JavaScript. But
the challenges you will face while building a back end are completely different than the ones
you face while using JavaScript on the front end.
