I'd like to announce Passbookster.
Passbookster allows you to create iOS passbook passes. It provides both
a stream and callback API. Great care has been taken on performance.
Node crypto module does not currently support PKCS#7 signing, so openssl
is spawned internally, but a PR to add this functionality is underway.
Shortly it will be used in a production system, so we've got you covered.
Github repo: https://github.com/danmilon/passbookster
Available as `passbookster` in npm.
Code is thoroughly documented.
Feedback / Issues / Pull requests are more than welcome!
