JSON incompatibility with node-mysql

[PRR24]

node-mysql2 returns deserialized value of MySQL JSON column while node-mysql returns string.
For updating/inserting, both require serialized string.
I think it is worth adding to "Known incompatibilities with node-mysql" section of the documentation.

Yes, agree. There was also some discussion to allow to change this behaviour via some config flag

Met the problem with TypeORM.😆

I also encountered this problem while attempting to switch our library from mysql to mysql2. A configuration flag would make it possible to switch gradually (ie. change the library and then afterwards change logic to handle deserialized objects)

Closing due to #2642.

It's now possible to use this option at the connection level:

{
  jsonStrings: true,
}

Also, the known incompatibilities section has been updated by @rubenmorim:
