isValid method?

[niftylettuce]

Other packages such as isemail, @hapi/address, and validator seem to have validation bugs. Parsing packages such as addressparser in nodemailer/lib/addressparser also seem to have issues when parsing certain addresses. It would be useful if this package exposed a simple isValid method which returned true or false. I'm assuming this could be a simple wrapper around parseOneAddress method which checked if the return value had a typeof with value of "Object" - but I haven't looked close enough yet to determine if that's the case.

It looks like this is the case. I don't write TypeScript and not sure if you would accept this PR.

Yes, @niftylettuce , that is accurate. In your code, you could write !!parseOneAddress(...) to get this functionality.

I would accept such a PR! I would like to do two things: 1) add a function parseOneMailbox that is exactly like parseOneAddress except it looks for one mailbox instead of one address (ts return type ParsedMailbox | null) 2) add function isMailbox(m) { return !!parseOneMailbox(m); } (ts return type boolean). Happy to receive a PR like that or I'll get around to it someday.

I don't write nor support TypeScript so unfortunately cannot contribute

@niftylettuce Watch out when using parseOneAddress for email validation, as current version (v3.1.0) can't properly handle invalid domains - see #53.
