MEAN stack (Can MongoDB be replaced with MySQL)?

Question

MySQL

Good afternoon, is it possible to replace MongoDB with MySQL in this stack.
Another question is how you can send data from Node JS to Angular. (As I understand it, this needs to be sent via json, but you can back it up with some simple example, otherwise something still doesn’t reach) If it’s not difficult and you found it on Google, you can also attach a link, they write about MongoDB everywhere, but about the stack with MySQL it's hard to find info

Answer 1

there is no MEAN stack. This is just a freely replaceable set of tools, and there is no point in taking a mongo at all. And this abbreviation was born back in the days of the first angular and eye-catching node, even before nest.js and typescript.
All the manuals of that period can no longer be taken seriously.

Answer 2

in the word MEAN, any letter can be replaced by another letter.
If you want fast and normal, take nestjs + graphql, apollo client + any framework.
spend some time to read what it's all about, lots of docks, but then you'll think about how to write your application, and not about how and what technologies / either to screw in order to make something work.
