To be able to host our note taking app, we need to upload the assets that are going to be served out statically on S3. S3 has a concept of buckets (or folders) to separate different types of files.

A bucket can also be configured to host the assets in it as a static website and is automatically assigned a publicly accessible URL. So let’s get started.

Create the Bucket

First, log in to your AWS Console and select S3 from the list of services.

Select Create Bucket and pick a name for your application and select the US East (N. Virginia) Region Region. Since our application is being served out using a CDN, the region should not matter to us.

Add Permissions

Buckets by default are not publicly accessible, so we need to change the S3 Bucket Permission. Select the Bucket Policy from the permissions panel.

And finally we need to turn our bucket into a static website. Select the Properties tab from the top panel.

Now select Use this bucket to host a website and add our index.html as the Index Document and the Error Document. Since we are letting React handle 404s, we can simply redirect our errors to our index.html as well. Hit Save once you are done.

This panel also shows us where our app will be accessible. AWS assigns us a URL for our static website. In this case the URL assigned to me is

Now that our bucket is all set up and ready, let’s go ahead and upload our assets to it.
