Is it possible to import existing javascript libraries in a javascript project?

I was looking for ECS support, but if I could import a custom js library like jprochazk's uECS that could also achieve that feature. If not, is the next best thing to create a compiled & minified version of a library and add that to a source file?

There is no way to import external JS. You can certainly try to copy / paste your lib to a new source file and use it that way.

I'll give that a try, thanks. Just getting started so ECS is probably not going to be a necessary optimization for a while. Cool project, though!
