How often is MongoDB used nowadays with the rise in popularity of PostgreSQL?

In my opinion we shouldn't compare NoSQLs like MongoDB with relational database systems. MongoDB isn't silver bullet for problems with database performance. In my opinion MongoDB is high performance in terms on reads and writes (and it also depends on data model) but it doesn't apply to scenarios which contain data aggregation and/or transactions.

Great example of MongoDB usage is as a persistent store in RabbitMQ. It fits all requirements for storing messages. But MongoDB is unsuitable for any king of transactional systems.

I personally faced the problem that customers don't trust MongoDB and they want to keep traditional databases like PostgreSQL. That in my opinion stops expansion of MongoDB. Please keep in mind that I'm not saying that we should throw away relational databases and replace it with NoSQLs.

Here is a list of MongoDB customers from official site. It's possible that you're using MongoDB without awareness (like in example with RabbitMQ).

Is the MEAN stack obsolete with the rise in popularity of other technologies like AWS, Azure, and Heroku, and frontends like React and Vue?

Maybe the peak of popularity of MEAN is behind us. MEAN as a concept was introduced in 2013. I agree that especially frontend technologies are changing rapidly (2-3 years for a frontend framework is an age). So nowadays React and/or Vue became popular too. That gives us ME R N or ME V N but it doesn't sound so nice like MEAN :)

AWS, Azure, Heroku are only platforms. For example you can ithout problem you can host your MEAN solution on Azure. You can create and host Node.js app use an Express as a backend framework, an Angular as a frontend framework and communicate with MongoDB or CosmosDB with exposed MongoDB API without any problems.

Please remember that are only my opinions. You can disagree with all my opinions, especially about frameworks lifecycle or MongoDB future. I'm not a technology oracle :)

Oh no, that's what I was wanting to get. I just wanted to hear from your experience if certain parts of that stack feel like they are showing their age a little bit or if you think they can still be considered modern.

I have a book that I bought like 3 years ago about Mongo, Angular, and Node, but it's been amazing to see how rapidly those platforms have evolved. Angular in plain ol JavaScript is aging with the rise of TypeScript and Dart. Wasn't sure if people also felt the same way about Mongo.
