Gary added on LinkedIn, “PSA from my inbox: The 15MB useful resource fetch threshold applies on the JavaScript assets, too, so in case your JavaScript recordsdata are bigger than that, your website might need a nasty time in Google Search. See googlebot.com for details about the fetch options and limitations. Sure, there are JavaScript assets on the market which are bigger than 15MB. No, it is not a good suggestion to have JavaScript recordsdata which are that giant.”
