  Hello. Welcome to another new tutorial on express JS. Today, we will be talking about a third-party middleware which is also a module called morgan . To follow along in this article, you should have basic knowledge of node js and express. If this is your first time learning about middleware or express js, I recommend you navigate to the node js section of this website and our YouTube channel to learn more. As commonly described, morgan is an http request logger middleware. That is, morgan middleware prints out the details of every request made from your application on the console or command-line. This is a handy tool used during the development process for testing an application. This is possible because it morgan is a middleware, and you know every middleware has access to the request-response cycle of an application.  Since morgan is a third-party middleware and module, it therefore needs to be installed before usage. To install morgan, navigate to your project directory ...

Wait for some time as npm downloads and installs this module ...

Hey!. In this article, we are going to talk about express js built-in middleware. If you are totally new in this, I recommend you check out my last articles on express js middleware by simply navigating to the node js section on this blog. From the word built-in, you can understand this middleware doesn’t need any installation and hence comes with express by default. On this blog, we are going to look at two different built-in middleware which are express.static () and express.json () . Today, we will learn about the express.static () middleware. Express static middleware is responsible or used to serve static files or static assets such as a webpage, files, images, style sheets, … This is very useful in the sense, when ever you include a static asset like images, stylesheet etc in your app, express first checks the folder holding static resources or files. It is mostly named the “public” folder for best practices and I also think its conventional. Whenever express finds a public fold...
