I have a use case where I need to create two schemas in production mysql database.I am connecting to these schema via sequelize from NodeJs.

I managed to create two instances of sequelize referring this, however the problem now is , how would I conditionally choose one of the two schema based on client side.As per the requirement, its my client who will decide which schema need to be used.There might be a variable being passed in the headers of request.How to read this on the server side and choose once instance of the sequelize conditionally.Please help as I am a newbie to this.

This is my code which is present in app.ts which connects to db, my use case is to call either of the two connection based on the flag passed from client side.

private connectToDatabase() {
   DB1.sequelize.sync({ force: false });
   DB2.testSequelize.sync({ force: false });
}
