For the following challenges, you are going to use MongoDB to store data. To simplify the configuration, you'll use a service called MongoDB Atlas.
Create a MongoDB Atlas account
MongoDB Atlas is a MongoDB Database-as-a-Service platform, which means that they configure and host the database for you. Then, your only responsibility will be to populate your database with what matters: data.
- Go here to sign up for a new MongoDB Atlas account.
- Fill the registration form with your information and click Sign up.
Create a new cluster
- Click the Create a cluster button under Shared Clusters. This should be the only free option.
- In the Cloud Provider & Region dropdown, leave this as the default (typically AWS).
- In the Cluster Tier dropdown, leave this as the default,
M0 Sandbox (Shared RAM, 512 MB Storage).
- In the Cluster Name dropdown, you can give your cluster a name, or leave it as the default,
- Click the green Create Cluster button at the bottom of the screen.
- You should now see the message
Your cluster is being created. New clusters take between 1-3 minutes to provision.Wait until the cluster is created before going to the next step.
Create a new user for the database
- On the left side of screen, click on Database Access.
- Click the green Add New Database User button.
- In the modal, enter a new username and password.
- Under Database User Privileges, leave this as the default option, Read and write to any database.
- Click the Add User button to create your new user.
Allow access from all IP addresses
- On the left side of the screen, click on Network Access.
- Click the green Add IP Address button.
- In the modal, click the ALLOW ACCESS FROM ANYWHERE button. You should see
0.0.0.0/0in the Access List Entry entry field.
- Click the green Confirm button.
Connect to your cluster
- Click on the green Get Started button in the bottom left of your screen should now show you the final step, Connect to your cluster, click on it.
- On the left side of the screen, click on Clusters.
- Click the Connect button for your cluster.
- In the popup modal, click on Connect your application.
- You should see the URI you'll use to connect to your database similar to this:
- Click the Copy button to copy your URI to your clipboard.
Notice that the
<db-name> fields of URI you copied are already filled out for you. All you need to do is replace the
<password> field with the one you created in the previous step.
And that's it — you now have the URI to add to your application and connect to your database. Keep this URI safe somewhere so you can use it later.
