We are building the messaging application in javascript using nodejs. As part of durability of the overall solution, we need to store text messages and media content outside ejabberd. To keep the text messages we used DynamoDB, DB as Service. But when we port-in the solution with different customers, customers are asking for different DBs for which they have licenses, like mysql, postgres, sql server, oracle, DB2, mongoDB etc...
Now my question is,
Just a thought, I looked at TypeORM, it does provide loosely coupled persistency layer to port-in with different back-end systems..., is this a feasible framework to take it forward. Happy to hear experts inputs.

TypeORM is a good candidate since it supports almost all the databases you mentioned (except DB2), I've worked with it and it's one of the best if you also want good typescript support.
