MongoNetworkError: failed to connect to server [localhost:27017] on first connect [MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017]

Question

I\'m new in nodeJS, started learning by following a trailer on youtube, everything goes well until I added the connect function if mongodb,

mongo.connect(\"m         


        

Answer 1

This worked for me.

mongoose.Promise = global.Promise;

  .connect(
    "mongodb://127.0.0.1:27017/mydb",
    { useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true}).then(db => {
      console.log("Database connected");
    }).catch(error => console.log("Could not connect to mongo db " + error));

I was using localhost, so i changed it to:

mongodb://127.0.0.1:27017/mydb
