How to install ExpressJS Using NPM (Node Package Manager) Within your CLI (Command Line Interface) - - Check if NPM is installed with $ npm -v (checking its version) If the version comes up, continue to installing ExpressJS via NPM with $ npm install express (You can also install ExpressJS GLOBALLY to be used within different NodeJS applications using $ npm install -g express) (I still recommend testing non-globally first)
After these installations are complete, you can continue to study and research the app.js template I've given you! Start by testing if the app works by running it with $ node app.js
Hopefully, you will be running your server and webpage locally and start on your own portfolios! Good luck and thank you again for coming out!
