Impossible to use cloudflare worker nodejs-compatibility mode due to transitive imports

[dsumac]

Context

• dev in cloudflare worker
• import and use statsig-node
• we want internaly use native api as explained here

Bug

• to use native api, we have to activate compatibility mode without add polyfill
• when we activate this option the worker expects an import like node:...
• there is transitively an import without prefix

• so we can not use your lib with native prefix import

Analysis

You use sha.js which use safe-buffer which uses native node Buffer api without node prefix import node:buffer

Hey @dsumac, thanks for sharing these details. We are aware of this incompatibility and plan to replace the sha.js dependency. Until then are you able to workaround this by using polyfills instead of compatibility mode?

[dsumac]

Thanks @kenny-statsig. We use node_compat = true(in our wrangler.toml config file) option to use polyfill. But it doesn't work. Error at deployement.

@dsumac Can you try adding compatibility_date. This works fine for me:

compatibility_date = "2023-01-20"
node_compat = true

[dsumac]

@cpreid , my explicate was maybe not clear.

Effectively this config it works. Even with an older compat mode. And this is this kind of config which works.

But I would like use native nodejs api in the same time, in the same worker code. Ex:

import { createHash } from "node:crypto";

const hash = createHash("valueToHash");

....

To directly use node api like this without polyfill we must activate nodejs compatibility flag: https://developers.cloudflare.com/workers/configuration/compatibility-dates/#nodejs-compatibility-flag

And when we activate this config, it doesn't work:

compatibility_date = "2023-01-20"
compatibility_flags = [ "nodejs_compat" ]

# we must disable node_compat to use compatibility_flags
# node_compat = true
