capcha for nodejs/express

I need to make capcha on my nodejs/express application. So I have the following questions:

  1. Are there any capcha projects for nodejs instead nodejs-recaptcha (the last commit was one year ago)?
  2. I'm interesting in "non standart" capcha like picapcha so it would be prefer to make this one in my project but unfortunaly it has no nodejs support yet. Are there the same project for nodejs/express personaly?

Besides nodejs-recaptcha there is not much to choose from.

  1. A quick search using toolbox.no.de for example gave me almost no results.

  2. I don't think it should be that hard to write the module yourself that interacst with picapcha.
