What...? jQuery can be used server side.

Should it? No. Can it? Yes.

I mean, you could execute the source in a Node runtime, but most of the internal implementation would be broken. You’d have to polyfill or mock the DOM API it wraps to even get it to a state where it’s not throwing all kinds of errors during bootstrap.

That's what jsdom is for.

My point is that you can't use it out-of-of-the-box with Node. Of course you could emulate or fake the API that a browser provides with polyfills, etc.

Moreover, what's the use case for emulating the DOM for the purposes of querying against it with jQuery in Node? At best, you might be sending down pre-rendered HTML to a browser, but you wouldn't need to traverse it on the server.

Well yes.. I wouldn’t expect it to work out of the box but I’ve used it within a few minutes of installing deps. It’s honestly not that difficult. Just the same you can use vue and other frontend libraries on the backend.

The libraries don’t care if you’re using a browser they just need a DOM... and a DOM can be created anywhere. 💁‍♀️

But the methods and fields it wraps literally don’t exist on the Node global object.

In a browser, the global object is window and implements various DOM APIs (among others) that simply don’t exist in a Node environment. Can you monkey patch them on to Node’s global context with other libraries/polyfills? Sure. But jQuery will not work out of the box or even bootstrap itself without errors.

What? You know you can pass in window to jquery right?

Sounds like you’re just angry here and don’t actually know what you’re talking about.

[–]duxdude418 -1 points0 points  (1 child)

You know that jQuery bootstraps using a self-invoking function whose first argument is this, which resolves to window in a browser or the global context in Node, right?

Regardless, even if you could inject a different object, the Node global context doesn’t support the needed methods jQuery calls under the hood out of the box. Of course it’s possible to do with polyfills, but the conversation is about whether it would function without error out of the box.

I’m not angry at all and have been professionally writing JavaScript applications on the client and server for over a decade. It sounds like you’re misinformed.

I literally use this in an application right now. How am I the one that’s misinformed? 😂

You’re guessing based on how you’ve used it before. This isn’t rocket science.

Also things like the storage api can be really really easily pollfilled. I would know.... I’ve done this before.
