there is another unfortunately named post that appears to be asking the same question, but is, in fact, not. this is actually asking how to do what I asked specifically.
I have a situation where we can't use NPM. not being as familiar with JS as I'd like to be, I want to use the vueDataTables library, but don't know how (or if) I can bypass the NPM-only install instructions and just download, link, and use it locally.
more generally, how would one use an NPM installed library when you don't have or can't use NPM and need to link the library locally?
