It's not a bug it's a feature :)

ShareJs should have a way to undo operations so it doesn't del docs to reserve the ids.

@zag2art but if I want to have unique indexes in MongoDB collection? They break down ShareJS.

@zag2art Do you know, when ShareJS deletes empty documents completely?

Never, If you want to do this you should do it manually. F. e. you can use server hook to catch the del-operations and use mongo native driver to remove the docs completely - (see https://github.com/derbyparty/derby-hook del hook)

I found that I should just add option "sparse" to unique index

Thank you! I guess it should be added to documentation if it wasn't.
