I built a plugin that adds a few custom blocks to guenberg and built a website using gutenberg. Today I wanted to test it with page speed insights and found out that my website has now a lot of render-blocking JS files... All these js files seems to be from gutenberg. My score is 40... What did I do wrong and how can I fix it? I have other websites with my custom blocks and these have 90+ score. Here is the list of render blocking JS files:

  • Did you do the test logged in? If so, repeat it from a browser where you're just a guest.

Ok so...
The problem was caused because I loaded these scripts on the front end in my plugin but these are needed only by editor. To solve this all I had to do was change the content of my block.json files - replace the "script" with "editorScript" so these js files are loaded only for editor :-)
