Hello everyone!

I am very much a newbie to FDB and after dealing with mysterious document validation errors today, I’m looking to learn something new. I’ve been using Mongo for _years_ and never learned anything else out of comfort, familiarity, and the fear of learning something different.

Anyhoo, does anyone have pointers on migrating a web app with Mongo as it’s database to FDB? I haven’t found any articles or blog posts detailing such a thing.

Hello,

It depends, the staightforward answer would be to recommend to look at the document layer at [https://forums.foundationdb.org/c/document-layer](https://forums.foundationdb.org/c/document-layer)

AFAIU that is not the way you can get the most of FDB. My preferred way is to “embed” it in my software (via a library) using one of the official bindings.

If you have large code base, using the document layer is the most straightforward.

I just found [this library](https://fdb.openland.com/docs), gonna work on implementing this when I wake up (it’s 2am!).
