The famous database... the one that generates joy, tears and anger in the ecosystem. Let's be clear: MongoDB is the most popular base in the ecosystem.
There is nothing to say about the native driver support… which makes it for me one of the strongest databases in terms of support. The MongoDB company also has very talented Node.js developers like Addaleax, which nevertheless reinforces the feeling of support and quality with regard to the tools that the publisher offers to the ecosystem.
I made my debut in Node.js and, like many, I followed the dance when I discovered MongoDB. It was an excellent experience for me who had only done SQL and I must say that I always rather enjoyed doing Mongo (it opened me up to other horizons and ways of thinking).
Nevertheless, I myself took the time from the beginning to read the documentation carefully because I had understood that I had to stop thinking in relational terms (without really knowing what that really meant at the beginning). My mission at BNP Paribas on the construction of a PaaS allowed me to push my mastery in particular on the management of shard data (with all the constraints that you eat on the corner of your nose).
Besides, I never understood the madness behind Mongoose and the idea of building relationships on a base that is not relationship...

After a few years, I can now tell you that I understand very well why many developers and architects complain about choosing MongoDB for projects where a relational database would have largely done the job.
It is true that many start projects on MongoDB when a base like PostgreSQL would have been a much better choice at all levels. Many therefore build gasworks or they try to make Mongo a relational base 😨.
I don't think we should go to extremes. If you are a junior developer I recommend that you experiment as much as possible with different databases.
