    works totally fine, go to frontent and run npm start to start client on port 3000

    to start backend run npm start on root directory.

    advice – hide your mongodb url, should not upload it publically.

    Looks like the application is not able to connect to mongodb.
    Make sure that the mongodb process is actually running.

    On linux you can check if mongodb is running with:

    systemctl status mongod

    If it’s not, start it with:

    sudo systemctl start mongod

    For windows ensure that you have the C:datadb folder setup.
    You can read more on the windows installation process here https://www.mongodb.com/docs/v3.0/tutorial/install-mongodb-on-windows/

    Then navigate to the C:Program FilesMongoDBServer3.2bin in cmd and run the command mongod to start the database
