Open-source Libraries and File Sizes
This list compares sizes of development and production version of libraries with and without compression. The compression schemes used for comparison are:
- PageCDN Size - PageCDN uses Brotli (q-11), the best in class for compressing resources over HTTP. The data is taken from PageCDN's implementation of brotli compression for respective libraries. PageCDN applies different compression level for different types of assets. For public resources, brotli-11 compression is used.
- Common Size - This is average size of compressed files served from different open source CDNs at the time these tests were performed. CDNs include Google Hosted Libraries, Microsoft Ajax CDN, CDNJS, jsDelivr, unpkg and some branded CDNs offered by libraries.
Below are the most commonly used open source libraries and their file sizes. All these libraries are available on the PageCDN's Public CDN.
Please note that file sizes may be inflated by 0.02 KB to 0.1 KB in some cases, as these sizes were recorded in Firefox browser
and include headers size when the server did not send the exact size in
Content-Length header. However, since the
'Common size' field below lists average size, the overall effect on numbers is expected to be negligible.
