Cant build a page with Sveltekit?

Hello I've been working on my Sveltekit app locally for a few weeks and wanted to try it out on Cloudflare pages. But it fails to build. What's going on?

Looks like you're using node 12 but at least 16 is required

James•1/14/23, 10:29 PM

Try bumping your

NODE_VERSION

NODE_VERSION

env var to 16

Walshy•1/14/23, 10:29 PM

Add the environment variable NODE_VERSION with the value 16

WWalshy Add the environment variable NODE_VERSION with the value 16

too slow

You can run packages with Functions, but you won't be able to run Node.js packages, or things that rely on Node.js modules, probably like mongodb.

James•1/14/23, 10:40 PM

Workers run JavaScript via V8, but not Node.js

WheyOP•1/14/23, 10:40 PM

aha :/

James•1/14/23, 10:43 PM

If your site is static, you could use these things in your build script and then output HTML from it

James•1/14/23, 10:43 PM

but you won't be able to hit something like Mongo with Functions today, at least not without some kind of HTTP transformer for the queries

Functions doesn't support arbitrary TCP (only HTTP), so even if you could use node_compat MongoDB is still not usable unfortunately

@Isaac McFadyen | YYZ01 thank you for clarification friend

Howdy hoo. We actually explored this stack. (functions didn't work for us)

our setup is as follows:

frontend
cloudflare pages

backend
cloudflare workers
websockets (not socket.io)

db
