I am testing a connection to a local DB using mongoose and mongodb. Whenever I specify a port when passing in the URI to mongoose.connect() I get a connection refused error,
async function connectDB() {
const db = await mongoose.connect('mongodb://localhost:<PORT NR>/myCollection')
return db
}
However, the connection works whenever I do not specify a port number.
async function connectDB() {
const db = await mongoose.connect('mongodb://localhost/myCollection')
return db
}
Why is this the case? I have used the port numbers: 3000,3232,27017 and 3456. All of which to my knowledge are not in use.
If you are running mongo in default port then you can try to connect in below way
function connectMongoDB() {
let uri = "mongodb://localhost:27017/<db_name>?authSource=admin&ssl=false";
mongoose.connect(uri, { useUnifiedTopology: true, useNewUrlParser: true });
const connection = mongoose.connection;
connection.once("open", function() {
console.log("MongoDB database connection established successfully");
});
}
