Node Modules

Intro

Node allows you to use code from other files. This is called ‘requiring’ or ‘importing’, and gives you the ability to share functions, variables, and logic between multiple files. Node also provides a few conveniences, such as a node_modules folder where you can easily reference modules, and a few built-in modules, like fs for accessing the file system and http for creating HTTP servers. Modules can also be downloaded from NPM.

Suggested Learning

• Node Modules Tutorial
• Modularity in Node - Just that section, although you should read it all 😉
• Node Docs on Modules - Read until ‘Accessing the Main Module’
• Loading Modules from node_modules Folder

Requirements

• Create a project with two files: index.js and stringGames.js;
• Create and export a function from stringGames.js which takes a string input and reverses it (eg: ‘Alex’ -> ‘xelA’)
• Create and export a function from stringGames.js which takes a string input and uppercases it and adds a bang (!) to the end (eg: ‘Alex’ -> ‘ALEX!’)
• Create and export a default function from stringGames.js which takes a string input with text and a string input for an emoji and adds the emoji input to the front and the end of the string (eg: ‘Alex’ and ‘🤓’ -> ‘🤓Alex🤓’).
• Have index.js require all of the functions from stringGames.js, including the default. Have it run all of the functions and console.log them.
• Upload your work to a Github repository and post it on the #requirements Discord channel to show you have completed it.

• Learn You Node - There is a section specifically for modules
