Issue

I have a mongodb cluster that has about 40 database that I need to selected based on some criteria.
Is there a way that I can use to select the database at runtime instead of passing in URI string ?
I have searched over internet and also in the issues & discord but couldn't find any answer.
Any help would be appreciated.

Could you use fastify.mongo.db(chooseDb(request))?
https://mongodb.github.io/node-mongodb-native/4.1/classes/Db.html

Or do you have 40 different connections?

Thatnks @Eomm for the quick reply.
I have one connection with 40 different databases.
I can't call fastify.mongo.db("dbname"), it shows error as Type 'Db' has no call signatures

@akhtar-husain >The fastify-mongodb client decorator should allow you to achieve what you want.

Can you try with something like this ?

const myMongoDatabase = fastify.mongo.client.db('dbname');
// your code here ...
