No problem~!

You shouldn’t modify any node_modules/** code – all your changes will be immediately lost anytime you install another dependency or if/when a coworker tries to replicate your setup.

Instead, you should do this in your testing setup file, or at the top of test files (repetitive):

// test/setup.js
global.WebSocket = require('ws');

Hey @tinchoz49 👋

No I would not, sorry. It would be meaningless to Sockette. You should simply do this instead:

global.WebSocket = require('ws');

This would only be set in your Node.js environment, leaving window.WebSocket intact for your browser bundle(s). If that’s not the case, then you will need to take a closer look at your build config because you should never have server code/deps in your front-end bundles. I can maybe help with this part if you have questions or issues.

The above will give you full support 👍
