I think it is possible to use this library with typescript without any modifications.

But I guess the type hinting for the options could be supplied. I am not familiar with typescript, so any suggestion/explanation of how this could work is welcome.

For those who need a quick fix until the actual types land, here's what I'm doing:

• Create _inquirer-autocomplete-prompt.d.ts somewhere reachable from your code, e.g. in src, with this content:

  declare module 'inquirer-autocomplete-prompt'

• Add this line at the beginning of every file where you import autocomplete from 'inquirer-autocomplete-prompt':

  /// <reference path='_inquirer-autocomplete-prompt.d.ts'/>

• Take care of the remaining types locally

I have no errors and the whole thing works.

I will review the PR to help this along.
Fixing it is out of scope for now, though, due to other work.

Type definitions are in DefinitelyTyped/inquirer-autocomplete-prompt (project page)

Just need to import @types/inquirer-autocomplete-prompt
