How to connect to mongoDB Atlas using mongoose
The answer in this related post is correct. You should:
- not mix options with connection string (if done so)
- make sure your IP you are running on is whitelisted and your network allows connections to Atlas
- make sure the user has sufficient permissions
use the connection string as is provided by atlas and just provide it to
mongoose.connect(uri);
const mongoAtlasUri =
"mongodb+srv://<username>:<password>@firstcluster.4rc4s.mongodb.net/<dbname>?retryWrites=true&w=majority";
try {
// Connect to the MongoDB cluster
mongoose.connect(
mongoAtlasUri,
{ useNewUrlParser: true, useUnifiedTopology: true },
() => console.log(" Mongoose is connected"),
);
} catch (e) {
console.log("could not connect");
}
const dbConnection = mongoose.connection;
dbConnection.on("error", (err) => console.log(`Connection error ${err}`));
dbConnection.once("open", () => console.log("Connected to DB!"));
MongoError: authentication fails - It means your name or password or dbname is not correct -
uri sample -
const uri =
"mongodb+srv://<username>:<password>@firstcluster.4rc4s.mongodb.net/<dbname>?retryWrites=true&w=majority";
Suppose username is - najim & password is 1234 & dbname is pets (Note - default dbname is test but you can write whatever you want) then my uri will be with above credentails -
const mongoAtlasUri =
"mongodb+srv://najim:[email protected]/pets?retryWrites=true&w=majority";
to connect with moongoose
try {
// Connect to the MongoDB cluster
mongoose.connect(
mongoAtlasUri,
{ useNewUrlParser: true, useUnifiedTopology: true },
() => console.log(" Mongoose is connected")
);
} catch (e) {
console.log("could not connect");
}
