Question

Compression for JS builds stored in Spaces

Hi! I’m storing React app builds (js, css and media files) in DO Spaces. Then the build is embedded in other app. Can I enable gzip or other compression in request headers? I noticed that there is such an option in file metadata but for some reason compression headers are still missing in the request

Hi there,

I believe that you might see this behaviour when using the Spaces CDN.

Origin endpoints do not dynamically compress or uncompress content, and they do not modify the content’s Content-Encoding header. However, for files downloaded via the CDN, you can set the following metadata headers during upload to the origin to make the CDN dynamically compress or uncompress the file:

  • The CDN endpoints may dynamically compress content, if the origin object does not have Content-Encoding: gzip and the client sends Accept-Encoding: gzip. If dynamically compressed, the resulting response has the Content-Encoding: gzip header added.

  • The CDN endpoints may dynamically uncompress content if the origin object has Content-Encoding: gzip and the client does not send Accept-Encoding: gzip. If dynamically uncompressed, the resulting response has the Content-Encoding: gzip header removed.

Hope that this helps!

Best,

Bobby
