Modifiers have changed a lot. I didn't want to make any decisions about what to include on this page yet so I included most of the functionality in the flip, preventOverflow and arrow modifiers.

I thought it would be nicer to depend on their types. It would be more correct to use Placement instead of ComputedPlacement but I wasn't sure if auto placements were left out on purpose.

Changed this recently. I'd rather use the correct types

For context, I have been collecting resources (started to) around how we could drop Popper in https://trello.com/c/WOj1Oase/2277-remove-popperjs. |

onUpdate needs to be a custom modifier now

Before altBoundary also affected flip but the behaviour is now customisable in both places.

Might, be too much info when using the correct types, but I would rather use the correct types and simplify for proptypes.

Nice to see the size decrease. We probably could drop this more using popper lite and importing the modifiers we use (https://popper.js.org/docs/v2/tree-shaking/#popper-lite) but we would only not import hide and offset I don't see a massive difference but will try it to see. Nice work @FezVrasta |

For some reason, eslint always changes this for me...

eslint shouldn't touch this file to begin with. What IDE + extension are you using to run eslint on this file?

Ah looks like it's a webstorm feature:
When checking if ESLint should be run on a .ts files, WebStorm 2018.3 analyzes the root config statically to see if it includes the following plugins:
"parser":"babel-eslint" or
"parser":"typescript-eslint-parser" or
"eslint-plugin-typescript" or
"@typescript-eslint/parser"
I can turn it off by adding typescript files to .eslintignore

Can't you tell webstorm to ignore it? Though it might resolve itself after #21758

As we are investing time in improving the relative positioning logic, we might as well keep the broader picture in mind and consider all our options. The broader choice of options we have, the best decision we can make. I think that now is a great opportunity to look at:
Now, there are longer-term considerations:

What issues do you see with the relative position logic apart from #21661? I've done some more investigation locally:

Breaking changes
Upgrade Popper.js from v1 to v2.
This third-party library has introduced a lot of changes.
You can read their migration guide or the following summary:
The CSS prefixes have changed:
popper: { zIndex: 1, - '&[x-placement*="bottom"] $arrow': { + '&[data-popper-placement*="bottom"] $arrow': {Method names have changed.
Modifiers' API has changed a lot. There are too many changes to be covered here.
Just wanted to see what kind of work was needed to migrate and have it run through the CI.
Relevant to: #19358
Closes #19358
