if you use next/image, then yes, otherwise, only the code that is sent is used...

also where is the 10mb bandwidth?

that should only use the cdn... vercel shouldn't charge you for it

ahh you have alot of middleware

yeah the response and request payloads are counted here

and when using image optimisation, that is also counted (every request, even if cached)

tbh i just do that...

but it can be benifitial to use optimised for lots

you can also use next/image and disable optimised images in next config

but i usually just ignore rule for them...

for this case, you should put your website behind cloudflare as they cache those js files on their cdn for free + free ddos protection - but you can loose things like knowing the request ip via normal means... (and idk how edge works with it)

you get a header from cloudflare, but you also need to verify that it came from cloudflare because otherwise with deployment url, it is easy to spam...

yeah... you may need to enable it (i didn't think so), but it is free and should reduce your costs
