HTTP/2 for Spotify Embed Widgets

reecestart — Wed, 23 Dec 2020 14:43:05 GMT

Hi,

When running the PageSpeed Insights[1] for my blog which I use Spotify Embed Widgets[2] to share music I am getting performance hits due to the JavaScript files used for the Widgets being served over HTTP/1.1 instead of HTTP/2[3]. The images also i.e. the Single or Album covers are also being served over HTTP/1.1 instead of HTTP/2.

An example JavaScript file[4] and an example image[5].

It looks like Spotify use Fastly as their CDN[6] and Fastly support HTTP/2[7] so this looks like a config change that could improve performance for everyone quite easily.

Thanks,
Reece

Agree. @Spotify should update this... The embed widgets are very slow.

Agreed!

This greatly affects the performance of everything using the Spotify CDN, including the Spotify product itself
