Where/How to "npm run install"?

When exploring different tools, I have found at least one module (and it’s intended theme) that includes in its installation instructions to Run "npm install".

Having not come from a coding background, I have no idea how to do this. After some digging, I did find that Cpanel does have a “Terminal”, but it doesn’t go into a folder to do something (that I know of–its one-time warning of the possibility of corrupting data made me VERY wary of trying to use it).

After exploring a ton of code on the backend, I became curious about the composer.json and package.json files and after lots of Googling, I think I found something: An Introduction to Package JSON Scripts in Node.js. This article makes me think that I can add "npm run install" in a package.json file under "scripts": {}.

If I combine that with the “Run … inside the folder”, do I just add a package.json file (or add to the one that’s already there) in that folder, making sure that it at least includes

"scripts" : {
    "postbuild": "npm run install"
}

? Is this right, or am I way off base?

You’re going a little off track there.

Things that say to “run npm install” in a particular folder mean to use something like the Terminal feature you mentioned, or an SSH connection, move to the desired folder (using the cd command) and then run the command npm install.

If you’re not comfortable with doing that, most addons will also offer a prepackaged version where you don’t have to do any of those “run a command” steps. The specific thing your screenshot is showing doesn’t seem to offer one, though.

Gotcha. After my current project, I’m going to make my own site where the whole thing is a sandbox that I can experiment with. Then I will brave the Terminal, so I may have more questions about it in the (near) future. But thank you for the speedy reply!
