I am new to Node.js and express. Now I am planning to use database for my application. I am used to with mysql. when I google about using database with node.js I found something weird like any-db node-sql or some kind of weird adapters that I need to use to access my normal mysql database. So which one should I use?
What about using https://www.npmjs.org/package/mysql I guess this is the most commonly used module for MySQL.

I'm creating a mobile app for an existing website and trying to connect to a local instance I have running on a MySQL workbench. I've seen others recommend against the use of MySQL but I'm stuck with it, since that's the current database. I'm using expo to run my React Native code. Do I need to use a server, like "MAMP?"
Let me know if there is any more info that is needed.
You cannot connect your app directly to your database.
You will need a server/API that acts as an intermediate between the app and the DB. You can code it in most programming languages and if you know PHP, having MAMP on your system will allow you to build your API with PHP.

You should definitely question their reasoning. I've been using MySQL for many years now in small and big projects and it has never been an issue. If they're comparing it to non-relational DBs like Mongo, I can understand, it's easier to setup and maintain a NoSQL database than a relational one.
I assume you're not that experienced but I still purposefully used some terms that may be new to a beginner. Since I don't know your skills, I will refrain from pointing you to specific tutorials/articles.
I recommend you to Google anything you don't understand from this answer.
Is there currently anything in the 2sxc module that allows you to connect to other database types? Specifically I would like to connect to a MySQL database. I know you can connect to other tables within the database.
This depends a bit on your question. Let's split
Can you use Razor-Views in 2sxc to visualize data from any kind of database?
Yes, just use c# code to get the data. Just create the sql-objects or whatever in .net and use that. For example, I wrote about using PetaPoco http://2sxc.org/en/docs/docs/feature/feature/2583
Can you use non-sql-data in your Visual Query Designer
Yes, but you'll have to work a bit. The easiest way is to map your my-sql tables in the DNN SQL server. This is a bit like a translation layer, which then let's use use them as if they were in the SQL Server.
A harder way is to create your own data source. Best to inherit the SqlDataSource (which provides a lot of security around parameter injection etc.) https://github.com/2sic/eav-server/blob/master/ToSic.Eav.DataSources/SqlDataSource.cs - and then modify it to use your mysql
I'm playing around with expressjs for a while and now the time has come to connect to a mysql database. Now i'm searching for a way to write and retrieve data from it. Normally i'm creating the database tables with MySQL Workbench. I'm using MySQL because of the ability of using ForeignKeys. Couldn't figure out yet how to do it in other database types...
Currently i'm more used to medoo for PHP. It only connected to a database and gave me the ability to access it in an object oriented way.
Is there a similar module for nodejs out there?
Try knex for a sql-builder library, it's pretty solid and looks sort of similar to medoo (but it uses Promises and is asynchronous).
I know rukilo is an UI framework for Dart language but I wonder if it supports to use Mysql? And if it is, how to connect mysql with Dart? Thank you
We are developing Rikulo ORM to simplify the database access (but it is not opened yet). The first version will be built on top of WebSQL (SQLite) and IndexedDB. We do have a plan to bridge it to the backend server such as MySQL. Of course, there are some security and performance challenges to deal with.
Can MySql database be used as a back-end of a desktop application. What are the various possible ways to do it?
I would say that it would be possible, with each desktop application client connecting to a centralized mysql database, at the client site, or possibly connecting to a centralized server managed by you/your company, and like #Neil Butterworth mentioned there are various APIs/methods to use to talk to the database. However, if you are looking to embed a database with your application, I would suggest looking at sqlite instead. It is a small,lightweight relational database designed for being embedded into applications.
To add to nstehr's answer, see:
SQLite vs MySQL
How scalable is Sqlite
How do databases work internally
Yes, I have done so on more than one occasion. Build your database in MySQL, either locally or on a remote machine, and then set up your connection to the database using the appropriate API.
There is a package for connecting to a .NET application (just search .NET MySQL library and it should turn up), with Java you can use Hibernate (or any other ORM Framework) and set the dialect to whichever version of MySQL you're using in the hibernate.config file. Or you could just use ODBC/JDBC directly. I'm sure other languages have their own support.
Any application, if built well, should be able to be supported by a variety of databases, and it should not affect the application. Switching between databases should involve changing a couple of property files at most, and then testing for database-specific idiosyncrasies.
Can MySql database be used as a
back-end of a desktop application
Yes, of course - just like any other database.
What are the various possible ways to
do it?
What do you mean? Do you mean how to access the database from the app? Lots of ways - some are:
via its native C API
via ODBC
via JDBC
Which one you use will of course depend greatly on which language(s) your desktop app is written in.
