Configuration file for Pages projects does not support "node_compat"
I'm having some compatability issues, where my code works on Workers but not on Pages Functions.
VHey. Pages doesn't support
node_compat, but it does support nodejs_compat, which is slightly different
J@Vero 
will this help? https://x.com/jasnell/status/1795872787594358875
or it is only for Workers (not Pages Functions)

A @Cloudflare Workers Node.js compatibility update... we will soon be enabling a revised version of the nodejs_compat flag (called nodejs_compat_v2) that makes a couple of key improvements to the implementation...

Wfunctions are workers
Wso it's available for them too
Wbut if it will help depends on your needs and what packages you require
Jknex is the package. and if they were the same thing, or functioned in the same way then node_compat flag would work the same as nodejs_compatJbut they do not.
WBeing the same doesn't mean the support is the same (long story)
Product explicitly decided to not support node_compat due to it being our not recommended thing

Jso then what is the solution? where this library works on Workers but not on Pages?

W?
Jwas just responding with a reproduciton repo - so maybe someone on the Workers/Pages team can get to the bottom of it
WAgain, not supporting node_compat was an explicit decision, it was not done intentionally. It isn't a bug.
Jso then what do you do in a case like this? just not use Cloudflare?
WFind an alternative library that does support edge runtimes.
Jif everything points to using Cloudflare Pages over Workers, but Pages doesn't support the same libraries
Jread the deploy log - it seems like it's a different limitation than the library itself
JError: Failed to publish your Function. Got error: Uncaught Error: Dynamic require of "events" is not supportedWyou or a library is doing a dynamic require('events'). This isn't supported by esbuild (the Workers/Pages bundler that Wrangler uses).
Jthen how is it working on Workers?
WThough
events
Wyou are clearly not doing this dynamic require when you did it with workers
Jit's the same codebase
Jboth those URLs above use the same repo
WOk. Well I said what the issue is.
Jso unless the action that deploys to Workers builds it differently, than idk?
https://github.com/cloudflare/wrangler-action

Jthis seems like something else, not a Node issue?
JThis is almost certainly due to
node_compat in wrangler + Workers being legacy, and doing weird things injecting node-specific APIs like eventsnode_compat isn't used, and therefore that eventsnodejs_compat_v2 in compatibility_flags might work - I've not personally tested much with it yet, nor am certain if it includes eventsnode_compat vs nodejs_compat is pretty confusing, but node_compat is thankfully being phased out so over time this should become much easier, especially now with the introduction of nodejs_compat_v2 which does fundemantally a lot of the same things, but without all the build-time hacks.JI'm building it with _v2
Jlets see
J14:26:22.477 Error: Failed to publish your Function. Got error: No such compatibility flag: experimental:nodejs_compat_v2
J3080aa6b-e5e7-43cf-a946-25209966bcd7Jis the deployment
JI'd recommend you first test this running locally with
wrangler pages devwell that error still stands
Jit seems like that command allowed it to build
Jjust get this error locally:
Jeven though it is
Jcompatibility_flags = ["experimental:nodejs_compat_v2"]JThe flag is still pretty experimental so it's possible you're going to hit bugs/issues with it, especially in Pages where it's likely been less tested. I'd recommend creating a minimal reproduction and filing a wrangler issue if you determine there to be an issue here
Jwhere should I make the issue
Jthat repo I linked is for the reproduction
Jthe flag flat out doesn't work 
Jhttps://github.com/cloudflare/workers-sdk would be the best place, but I'd showcase this without
node_compat. Pages doesn't support that intentionally, and almost certainly never willJwhat?
Jthe repo isn't using
node_compat=true, that's for the Workers deploymentJ@James maybe this needs to be enabled on my account?
JIt’s not an advertised or documented thing yet - it’s just early and you’re on the bleeding edge while it’s still being worked on. There’s nothing to enable on your account as far as I know.
