Compat Flags/Dates are there to ensure that Workers never break. Someone’s script may rely on a flag not being set, which would break if it was set by default

Yeah, but the docs says that this flag will never be enabled, not even in future compatibility dates

That's why I was wondering what's special about this one. Seems like a great feature which unlocks a lot of packages, and yet it's "hidden" behind a flag.

Does it work if you build with

esbuild

manually? I'm guessing it might be that

support was added to

Let's say I have several Functions in a Pages project and I want to call one Function from another, does the request go through public internet or internally in the worker (that was generated for the functions)?

Particularly interested if I call a Function from my Astro SSR (which runs in a Pages Function) will introduce latency due to going through public internet?

Hi guys. Is that function code from official Website working for you? I'm getting back:

✘ [ERROR] Could not resolve "@cloudflare/ai"


import { Ai } from '@cloudflare/ai'

export async function onRequest(context) {
  const ai = new Ai(context.env.AI);

  const input = { prompt: "What is the origin of the phrase Hello, World" }

  const answer = await ai.run('@cf/meta/llama-2-7b-chat-int8', input);

  return Response.json(answer);
}

  return Response.json(answer);
}

I can run the Worker AI (different code). However I'd like to run the AI model within a Pages function as well. Am I missing something here?

Have you installed the package with a package manager? i.e

npm i @cloudflare/ai

npm i @cloudflare/ai

j3st3r•10/24/23, 12:59 AM

Hi @kian , I'm not running the app locally, I'm deploying it directly to Cludflare by connecting a GitHub repo to Pages. Is still needed I run some command?

J

j3st3r•10/24/23, 1:02 AM

maybe is some Build configurations needed? i.e npm i @cloudflare/ai command into Edit build configurations - > Build command setting panel?

J

j3st3r•10/24/23, 1:06 AM

Wow, it worked! Thanks a lot for your hint @kian, you were totally right!

hello everyone, what is the best place to add platform:node when using functions and no wrangler.toml file exists? I am facing following error when deployng:

  The package "crypto" wasn't found on the file system but is built into node. Are you trying to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

James•10/25/23, 1:38 AM

With Functions, generally you can’t. There’s very little options in terms of custom bundling, and that specific error is from esbuild anyways.

J

James•10/25/23, 1:38 AM

Your best bet would be to use a package that’s more compatible with Workers. What are you trying to do?

Hav you tried importing "node:crypto" instead? with the nodejs_compat flag? https://developers.cloudflare.com/workers/runtime-apis/nodejs/crypto/

The `node:crypto`` module provides cryptographic functionality that includes a set of wrappers for OpenSSL’s hash, HMAC, cipher, decipher, sign, and …

It’s not a package, just a global.

Nothing to import - just use it

const uuid = crypto.randomUUID()

const uuid = crypto.randomUUID()

If you did want NodeJS crypto; you add the compatibility flag in Pages Functions settings in the dashboard and do a new deployment but it needs to be referenced as node:crypto, not just crypto
