I am using mongodb with loopback and on successful connection I am getting below warning
Top-level use of w, wtimeout, j, and fsync is deprecated. Use writeConcern instead.
loopback version: 5.5.0
How to get rid of this? Kindly help
Apparently this warning was introduced in Mongo Driver v3.6.4 so the basis solution will be to down grade to v3.6.3. There is a PR that try to stop the warning outputs, and also a report on the Jira for the Node Driver. https://jira.mongodb.org/browse/NODE-3114
Update: The problem have been fixed with the version 3.6.5
Pass the following options
mongoose.connect(process.env.MONGO_URI, {
useNewUrlParser: true,
useFindAndModify: false,
useUnifiedTopology: true,
useCreateIndex: true
})
