Module basics
- First, it'll let us load in modules that come bundled with Node.js. These include the HTTP module, which lets us make a web server, and the fs module, which lets us access the filesystem for our machine.
- We'll be able to use prewritten libraries to handle complex problems, and all we need to do is implement require() by calling a few methods.
- We will use require() to require our very own files. It will let us break up our application into multiple, smaller files, which is essential for building real-world apps.
Using case for require()
Initialization of an application
cd Desktop
mkdir notes-node
cd notes-node
The built-in module to use require()
console.log('Starting app');
Creating and appending files in the File System module
- One will be the file name
- The other will be the data we want to append to the file
