If you'all get an error says - the 'uri' parameter to open ()uri must be a string.
Insert your mongodb connection link inside- mongoose.connect('link',
Like this

hi.. I got this error.. plz help on it.
Error: The `uri` parameter to `openUri()` must be a string, got "undefined". Make sure the first parameter to `mongoose.connect()` or `mongoose.createConnection()` is a string.

[avanisoam]

[realAgitated]

I am not seeing any messages about my database starting, and I am not getting any errors. I just keep seeing my server and client restarting with no errors but I never get any mongodb errors or successes anyone can help me?

[mehakmattoo]

Make sure to remove the angular bracket before, after the password, replace the space by an underscore and add your database name before the ? in uri

const notes = require("./data/notes");


const connectDB = require("./config/db");

dotenv.config();

const app = express();

This was helpful. Would have been great if you could show how to host the entire app (including the database). Thanks

[jaskaranminhas]

this content is very helpful. but i have a issue. mongoose.connect( ) is not working. it says first argument must be a string. i have tried many thing but nothing happen.

[jadabouzeid]

Hello, thank you for this tutorial it's really helpful! When I tried to run backend I got the following Error: option usecreateindex is not supported. But once I deleted the line of useCreateIndex it worked just fine. What is the reason for this error?

[sayanmaitra]

Having Problem to connect MongoDB ~ remove useCreateIndex:true, this line :)
