warframe-items | 📘 Get all Warframe items | REST library

Apologies in advance if any of these questions have already been asked but I am a bit of a noob in this area.

Firstly I'd like to say that I have been taking the courses on Freecodecamp (Which is awesome) and I now believe I am ready to start my first project. I haven't done all the courses yet and I will be going back to them soon enough but I know html, CSS and JS. The questions I have are not around using Node, NPM and GIT but how they all tie together and what happens in between. It's hard to explain exactly what I'm trying to say so I'll jump straight in with an example.

I learn best by reverse engineering and I want to build a website like https://witcher3map.com/. They have it all available on GitHUB here https://github.com/witcher3map/witcher3map so I decided to see if i could set it up on my machine and reverse engineer it etc. I know some bits and not others so I'll write my questions out like I'm following their instructions and ask questions when I need to:

Questions

• I installed node and GIT and cloned the repo with no issues. Now my first question around this is that I created a folder called witcher3map but when i cloned it, it created another folder called witcher3map. So now, it is witcher3map/witcher3map. Can i just move it up one folder or does GIT somehow save these paths and other config info somewhere and it will make GIT get confused?

• i then ran NPM install - Now I believe NPM looks at the package.json file to find out what dependencies it needs to DL, is this correct?

• Once the dependencies are downloaded, if i then sync the repos again does it upload the dependencies to GIThub? I obviously don't want this and if it does I assume there is a switch or some command to prevent this from happening?

• The next command tells me to run "grunt build" but when i try this it errors. I think it's because I don't have Grunt installed? But the instructions don't tell me to install it. Even when it is installed can someone tell me how "build" gets executed? I guess it goes to a sub folder and loads a grunt config type file which has the build instructions in it but how does it get there?

EDIT: Some more info - Grunt is a dependancy and it downloaded it fine. When i run "grunt build" I am running from the GIT Bash CLI and it says "command not found", do I need to run it in node rather?

• The same goes for "grunt server"

I have also seen in other projects other commands I am finding hard to understand. For example on https://github.com/WFCD/warframe-items it says that after cloning the repo, to use the app you type

const Items = require('warframe-items')

I mean what does that mean? I'm sure it makes sense to seasoned DEVs but not me. Can anyone elaborate on this?

My final question is that on some other projects I also see commands/switches where they say things like "build" or ways to build a DEV build or prod build. How do I trace those said commands to ultimately open a file to see exactly what "build" does?

Thanks,
