      title: 'Bucket Browser', // prefix value with `HTML> ` to render as html, see subtitle
      subtitle: 'HTML>made with ♥ by <b><a href="https://qoo.monster">qoomon</a></b>', // prefix value with `HTML> ` to render as html
      logo: 'https://qoomon.github.io/aws-s3-bucket-browser/logo.png',
      favicon: 'https://qoomon.github.io/aws-s3-bucket-browser/favicon.ico',
      primaryColor: '#167df0',
      
      bucketUrl: undefined,
      // If bucketUrl is undefined, this script tries to determine bucket Rest API URL from this file location itself.
      //   This will only work for locations like these
      //   * https://s3.amazonaws.com/BUCKET-NAME/index.html
      //   * https://s3.BUCKET-REGION.amazonaws.com/BUCKET-NAME/index.html
      //   * http://BUCKET-NAME.s3-website-BUCKET-REGION.amazonaws.com/index.html
      //   * https://storage.googleapis.com/BUCKET-NAME/index.html
      //   * https://BUCKET-NAME.s3-web.BUCKET-REGION.cloud-object-storage.appdomain.cloud/
      //   * https://BUCKET-NAME.BUCKET-REGION.digitaloceanspaces.com
      //   * https://BUCKET-NAME.BUCKET-REGION.cdn.digitaloceanspaces.com
      // If bucketUrl is set manually, ensure this is the bucket Rest API URL, e.g.
      //   * https://s3.amazonaws.com/BUCKET-NAME
      //   * https://storage.googleapis.com/BUCKET-NAME
      //   The URL should return an XML document with <ListBucketResult> as root element.
      rootPrefix: undefined, // e.g. 'subfolder/'
      keyExcludePatterns: [/^index\.html$/], // matches againt object key relative to rootPrefix
      pageSize: 50,
      
      bucketMaskUrl: undefined, 
      // If bucketMaskUrl is set file urls will be changed from ${bucketUrl}/${file} to ${bucketMaskUrl}/${file}
      //   bucketMaskUrl: 'https://example.org'
      //     => https://example.org/foo/bar.txt 
      //   bucketMaskUrl: document.location.origin
      //     => ${document.location.origin}/foo/bar.txt 
      
      defaultOrder: 'name-asc' // (name|size|dateModified)-(asc|desc)
    }

  • Depending on your setup you may need need to ensure following CORS Configuration
  • Go to https://s3.console.aws.amazon.com/s3/buckets/<YOUR BUCKET NAME>/?tab=permissions
  • Grant Cross Origin Access by following CORS Configuration, replace http://www.example.com by your address of bucket browser index.html
    • e.g http://example.s3-website-eu-central-1.amazonaws.com/index.html

    [
      {
          "AllowedHeaders": [
              "*"

          "AllowedOrigins": [
              "http://www.example.com",
              "https://BUCKET-NAME.s3.amazonaws.com",
              "https://s3.BUCKET-REGION.amazonaws.com/BUCKET-NAME",
          ],

• Open <YOUR BUCKET URL>/index.html in your browser.

Hosted

• ⚠️ Ensure Bucket Permissions

  • see Self-Hosted

• ⚠️ Ensure Bucket CORS

  • see Self-Hosted
• Open hosted index.html in your browser and provide bucket url as bucket request parameter
  • ${INDEX_FILE_LOCATION}?bucket=${S3_BUCKET_URL}
  • e.g. https://qoomon.github.io/aws-s3-bucket-browser/index.html?bucket=https://s3.eu-west-1.amazonaws.com/data.openspending.org

CloudFront Setup

If you use CloudFront in upfront of your S3 bucket ensure following CloudFront settings.

• Allowed/Cached HTTP Methods: GET, HEAD, OPTIONS
• Cached Based on Selected Headers: Whitelist
  • Access-Control-Request-Headers
  • Access-Control-Request-Method
  • Origin
• Query String Forwarding and Caching: Forward all

IBM Cloud Object Storage Setup

IBM Cloud Object storage only supports virtual host-style addressing, i.e. https://<bucket-name>s3-web.<region>.cloud-object-storage.appdomain.cloud/ for static website hosting. Otherwise follow the instructions in this tutorial to configure your bucket. In addition, you may need to configure CORS for your bucket.

<CORSConfiguration>
  <CORSRule>
      <AllowedOrigin>*</AllowedOrigin>
      <AllowedMethod>GET</AllowedMethod>
      <AllowedHeader>*</AllowedHeader>
  </CORSRule>
</CORSConfiguration>
