What causes the namespace to shift when utilizing npm for installing a library?

I've been attempting to integrate whammy.js into a project. The initial line in the source code is

window.Whammy = (function(){

yet, after running npm i and inspecting node_modules, I discovered

global.Whammy = (function(){

https://github.com/antimatter15/whammy/blob/master/whammy.js

{
...
    "dependencies": {
        "cordova": "^9.0.0",
        "react": "^16.8.5",
        "react-redux": "^5.0.6",
        "redux": "^4.0.1",
        "redux-actions": "^2.2.1",
        "redux-thunk": "^2.2.0",
        "whammy": "0.0.1"
    },
    ...

Is there any insight as to what may be causing this discrepancy? I initially suspected webpack, but it doesn't seem like that's the issue.

Answer №1

It appears that you may be attempting to use a backend npm package on the frontend of your application, which could explain why the global object in the browser changes from window to global after installation, as global is typically used in Node.JS (backend) environments.

Upon inspecting the Whammy page, it seems to demonstrate direct frontend usage without the need for npm installation:

<script src="whammy.js"></script>

You can simply download the file directly and incorporate it into your site this way.
