Setup MongoDB Atlas Account

For the MongoDB workshops, we will be using mongoDB Atlas. It is a cloud DB service.

Go to mongodb.com and click Start Free.

Use the google signin to accelerate the process.

1. Sign up with Google
2. Accept Privacy Plicy and Terms...
3. Create an organization
4. Create a project
5. Build a cluster
6. Choose the FREE tier
7. Accept the default settings

...your cluster is being created (This can take a few minutes.)

Create a Database

• Create a database called exercise_1
• Create a collection called users

Access credentials to the database

Create a Database user

1. Select 'Database Access' from the sidebar
2. Add a new Database User
   • Use Password for the authentication method.
   • create a username and password (use the Autogenerate Secure Password option)
   • copy that password and paste it somewhere temporarily.

Access the database

1. Select Clusters from the sidebar.
2. Click on Connect in the cluster box.
3. Whitelist your i.p. address.
4. Choose a connection method.
   • Use the second method: Using MongoDB's native drivers.

In the last pane, there is a code snippet. In that code snippet, there is a uri. It will look something like this.

const uri =
  "mongodb+srv://user31:<password>@cluster0.9oceg.mongodb.net/<dbname>?retryWrites=true&w=majority";

1. Create a .env file
2. Add the uri to that file.

MONGO_URI=mongodb+srv://user31:<password>@cluster0.9oceg.mongodb.net/<dbname>?retryWrites=true&w=majority

Replace <password> and <dbname> with actual values.

• <password> is the password you assigned to the user you created in the previous step.
• <dbname> is the name of the database.
