We will learn how to create a program in Node.js to run common commands like ls, mkdir or even npm on your Unix system (Mac or Linux). If you just want to see the code, you can view it on Github The Child Process Module When we execute shell commands, we are running code outside of our Node....

When a user logs into our application, we need to know who they are across all our HTTP methods and routes. One way to do this is to store the users “session”.
