NodeJS MongoDB UNIX socket connection

In a nodeJS app, I'd want to connect to my MongoDB database via its UNIX socket /tmp/mongdb-27017.sock. I use the package https://mongodb.github.io/node-mongodb-native/?jmp=docs (version 3.1.6), this way:

const client = await MongoClient.connect("mongodb://%2Ftmp%2Fmongodb-27017.sock")

The URI is referenced in the doc here: https://docs.mongodb.com/manual/reference/connection-string/#unix-domain-socket. But in my case it fails with the error:

MongoNetworkError: failed to connect to server [/tmp/mongodb-27017.sock:27017] on first connect [MongoNetworkError: connect ECONNREFUSED /tmp/mongodb-27017.sock]

Do anyone know if it's possible to connect to a mongoDB UNIX socket from nodeJS, and if there's something specific to do? Couldn't find specific info in the doc.

For me the solution was not to escape the path, contrary to the documentation on docs.mongodb.com. So try

mongodb:///tmp/mongodb-27017.sock

instead of

mongodb://%2Ftmp%2Fmongodb-27017.sock

And of course make sure the socket file exists:

$ ls -al /tmp/mongodb-27017.sock
srwxrwxrwx 1 mongodb mongodb 0 Apr 1 21:47 /tmp/mongodb-27017.sock

A more complete example using a user account from another database then the one we're connecting to:

mongodb://foo:pass@/tmp/mongodb-27017.sock/somedb?authSource=admin

Here a connection is made to the somedb database, by user foo which is a user account stored in the admin database.

It is possible by using the full Unix domain socket paths instead of hostname on which mongod should listen for client connections. It started in Mongo 3.6
