yes that's true, what I was saying is that for some modules (the most used and the ones with the most stable polyfills), shipping them with the runtime makes sense, but for others no (like rarely used modules or ones with polyfills that are not stable/well maintained)

so I think the runtime team wants to strike the right balance there

yes, for sure, but there's a lot of such packages, also many are not properly maintained and the maintainers are not interested in switching to something else (and aren't even willing to accept contributions from us)

I have a question, is it a good idea to have link prefetch enabled by default ?

Nob•3/30/24, 11:30 AM

I get like 30 worker executions per page just because nextjs like to prefetch everything

the cynical view would be more requests = more money

Nob•3/30/24, 1:01 PM

yes but in nextjs you can either disable it completly (not even on hover) or enable for viewport

zegevlier•3/30/24, 1:15 PM

Does that not go against the backwards compatibility philosophy of workers? Putting it somewhere other than the runtime because that allows for breaking changes seems to me like trying to exploit a "loophole" in the rules around backwards compatibility.

zegevlier•3/30/24, 4:01 PM

It would require you to stick with old, unsupported, versions of wrangler if you want to make sure your worker keeps working as expected. The only reason I can see for not using compat dates is because you plan to break backwards compatibility at some point, and that feel very wrong to me in workers. While you are correct that this wouldn't technically violate the backwards compatibility guarantees (a change in this wouldn't be a change in the runtime, and deployed workers would keep working), it still doesn't sit right with me.

Deo Kumar•3/30/24, 6:37 PM

Does blob: fetch not work on next on pages?
Like:

fetch(new URL("../noto-sans.ttf.bin", import.meta.url))

The above works in development mode but doesn't work when using npx wrangler pages dev

DarioOP•3/30/24, 11:18 PM

I see... the way I see it is sort of like: we don't have a perfect solution, so, instead of adding to the runtime something half-baked/problematic right now (thus committing to it forever) let's find an intermediate solution that can help people out to some degree, best-effort like. That being the build time node_compat flag.

That does make sense to me.

Also people with much more knowledge in that area than me made the decision above (which I don't know how set in stone is to be honest), people who know the downsides and maintenance burden of adding such polyfills into the runtime, so I trust their judgment

, but if you want I am totally happy to pass your feedback along or see if I can connect you directly with them

Upon inspecting the _worker.js folder in the .vercel/output directory after running "npx @cloudflare/next-on-pages" in my Next.js app, I noticed a JSON file named "nop-build-log.json." It's hefty, around 262 kB, free tier limit for Workers is 1 MB after gzip compression. My question is: Is the "nop-build-log.json" file essential for running the application? Also, does Cloudflare Pages upload this file during deployment via the dashboard with Git integration?

P.S.: Cloudflare is fantastic! I truly enjoy using their services, especially the supportive community. I plan to upgrade my account to a paid tier eventually, as my application will likely exceed the 1 MB limit in the future. My point here is to try to reduce the bundle size of the code and understand how the system works.
