Cloudflare

local is very much an emulation, it's a best effort

production is where you'll see this for real

it may still act this way but i don't know

this feels like a fairly enormous limitation. everything does seem to work as expected in `--experimental-local`, so as I said at the start, i do think this is a bug

If it works in experimental local why not just use that then?

Just as experimental as the other local tbh. Local will only ever be so good compared to deployed

i mean, i understand that intellectually, but that seems pretty terrifying from a developer experience perspective

`dev`, which is ran on the Cloudflare edge remotely
`local`, which is ran in Miniflare 2 which is a Node emulation
`experimental-local`, which is ran in Miniflare 3 which wraps `workerd`, the open-source runtime

I personally always use normal `dev` since it's, well, running as a Worker actually would

That isn't an option for `pages dev` and so users of Pages/Functions can only use `local` or `experimental-local`

that's helpful, thanks -- so to clarify, when i run `wrangler dev myscript`, that's literally running my code on the CF edge network?

and somehow proxying it back to my local machine?

ahh, i see. my issue with that is it clogs up my dashboard

but, i do get it, and it seems like a good alternative

fwiw.... Date.now() works totally as-expected via `wrangler dev`

given our conversation, i am surprised by that

local mode -> doesn't work
dev -> works
experimental local -> works

`wrangler dev` should, barring any bugs, be exactly the same as the resulting Worker from `wrangler publish`

Only coding in production <a:ohyeahohyeahohyeah:818920634905002026>

i'm glad to know that wrangler dev is ~production environment, but what i don't understand still is how the Spectre thing makes any sense

like, if the whole point was nerfing Date.now() to avoid spectre... how come the nerf only applies in local?

Yeah true wrangler dev is basically a proxied deployed worker in a way so should be most accurate followed by experimental local since it uses the open source runtime then local

that seems to completely defeat the point. if anything, you'd want the opposite behavior

It's nerfed in production and experimental-local

You might see a delta, but it isn't real as far as accurate, out-of-Worker timing.
