Server Discovery And Monitoring engine is deprecated

Question

I am using Mongoose with my Node.js app and this is my configuration:

mongoose.connect(process.env.MONGO_URI, {
   useNewUrlParser: true,
   useUnifiedTopol         


        

Answer 1

I was also facing the same issue:

1. I made sure to be connected to mongoDB by running the following on the terminal:

   brew services start mongodb-community@4.2
   

   And I got the output:

   Successfully started `mongodb-community`
   

Instructions for installing mongodb at
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/ or https://www.youtube.com/watch?v=IGIcrMTtjoU

2. My configuration was as follows:

   mongoose.connect(config.mongo_uri, {
       useUnifiedTopology: true,
       useNewUrlParser: true})
       .then(() => console.log("Connected to Database"))
       .catch(err => console.error("An error has occured", err));
   

Which solved my problem!
