chore: upgrade eventemitter to v5.0.2 #7709

ozyx · 2024-05-02T00:01:02Z

Closes #4656
Closes #6426

Describe your changes:

Upgrades eventemitter3 library to the latest version 5.0.2.

Removes unused event listeners (registering listeners without context or unregistering non-existent listeners now raises an exception).
Converts DrawWebGL and Draw2D to ES6 classes so they can inherit from EventEmitter without losing context.
Includes the context in listeners registered with eventHelpers

this.togglePreviewState was undefined, and this wasn't doing anything except making our unit tests fail. It seems that the new version throws an exception if you try to unregister a listener that doesn't exist, or register a listener without context.

I think you're right. I wonder if our preview action changed at some point as it doesn't seem to have much benefit to emitting this 'isVisible' event at all.

It seems that the new version throws an exception if you try to unregister a listener that doesn't exist, or register a listener without context.

From v3.0.0 onwards, EventEmitter3 throws an error if you try to register a listener with a callback that is not a function

Actually, this is being used for search results here:
https://github.com/nasa/openmct/blob/master/src/ui/layout/search/SearchResultsDropDown.vue#L48
It was likely a copy-paste error where the this.togglePreviewState method was not added. It is also missing in AnnotationSearchResult.vue

You can see an implementation here:

Whaaaat were we even doing here? Suspect this was a hangover from prototypical inheritance that was left in by mistake.

Yup, exactly.

Wait, so how was this working before? The context would have been undefined?

Changes look good to me. My only question is all the cases where we are now providing a context object for the callback function. Why is that suddenly necessary, and how was it working previously with an undefined context?

I don't think we can have aliased imports due to the JPL codebase @davetsay @jvigliotta

This is only true for files that they import directly from source (🙈). @jvigliotta @davetsay which files are we honor-bound to keep webpack-alias-free?

Good looking out, @unlikelyzero . We'll fix this on the OMM side. Core should not worry about using or not using aliased imports. As long as we use the same webpack aliases in OMM it will work (🙈+1).

Changes look good to me. My only question is all the cases where we are now providing a context object for the callback function. Why is that suddenly necessary, and how was it working previously with an undefined context?

In v1.2.0 (and beyond), if no context is provided, it will fall back to using the EventEmitter context, which seemed to work for our purposes before. As a part of these changes, I converted Draw2D and DrawWebGL to ES6 classes, so the default context there becomes the class instance instead of the caller. So we need to explicitly pass the context to the EE to preserve the previous behavior.

davetsay

Great work, @ozyx. Definitely more worthy work than chore gives it credit for.
