Please document text-moderation and moderate-images in TypeScript

I would love to use the code shown in [this article](https://firebase.googleblog.com/2017/06/content-moderation-with-cloud-functions.html), but all my Firebase Cloud Functions code is in TypeScript instead of Javascript.
I'm trying to submit a dating app to the Apple App Store but Apple wants me to implement some inappropriate content filtering. If I could simply implement what you show in this article, it would be amazing, but I can't figure out how to integrate `bad-words`, `@google-cloud/vision` and `mkdirp-promise` in my `index.ts` file. Please help.
