shopify_v2.js) thereby considerable improving the overall loading speed of your shop. Additionally, there are not database calls to fetch review content, as this is saved inside Shopify metafields.
Our JS file is 77.4 KB after compression (before compression it's 210KB, but for network loading performance the size prior to compression is irrelevant). While this by itself is a relatively large file size (it's ~2 times as large as jQuery-1.9.1.min, which is ~36.5KB after compression), it's the only request that we make.
Other review apps usually make 4 separated requests for the above items (some even unnecessarily load the whole FontAwesome library). Most apps also make database requests to fetch their review content. Judge.me stores review content inside Shopify metafields, embedded in your page in order not to make extra database requests. Loading review content from Shopify metafields has been part of the free plan since the Judge.me widget version 1.0.
One large request outperforms many small requests (e.g. 1 request of 50KB is faster than 5 requests of 10KB) because most of the time spent for a request is for overhead procedures, such as looking for a server, initiating SSL handshake, server processing.
Google PageSpeed does not deduct any point just because our JS file is large. It only does so if the JS file is not compressed, or not minified, or not loaded asynchronously, or not cached. However, our JS file does not have any of those issues.
We add jQuery for multiple reasons:
