Having types file here will make sure the types and codebase are in sync.

LGTM. Could you please also add some guidelines on how to use, on the README? Perhaps adding a section for Types?

[rubiin]

Sure thing. I will update the readme for this

[rubiin]

Since the types get installed along with the library, there is no need to install @types/validator package anymore for typescript support. I have added a small section on readme for that but we should also point this on the realease notes @profnandaa

+1 for this one, I've been checking the latest @types/validator version doesn't include the type for isAbaRouting. It seems this PR is outdated because this type is missing here too.

[rubiin]

Yeah . Since we have types file here , we dont have to depend on the @types/ packages . They can be slow and outdated so self managing is a better option

[rubiin]

For now we can ship this and on later date , break it down on smaller files.
