I Wonder if you're planning to launch any course related to MongoDB soon. I think many folks need to wrap their mind around the integration with Laravel.
@KNietzsche GraphQL can be adapted to use with any DB. Currently, it is just common to see it with MongoDB. There are many online discussions and articles about using GraqphQL...it is the future and it is extremely easy to use. Just think of it as layer that provides you a means to never ever have to actually talk to your DB and it only returns the data you requested, nothing more and nothing less.
