title: remove index.html from URL react app on S3 and CloudFront
body: <p>I am hosting multiple react apps on one s3 bucket, that is connected to a CloudFront distro.
  The react apps are placed in folders so for example the calculating app is located in /calculate in the S3 bucket.
  I fixed issues that happened because react wasn't using paths in a relative way to the index.html (I added &quot;homepage&quot;:&quot;./&quot; to the package.json). But I am struggling to remove the index.html from the URL for the end user.
  Basically I want the index.html to appear when going on https://{domain}/calculate/ not https://{domain}/calculate/index.html . Does someone know how to fix this issue?</p>
  <p>Thanks</p>
