the code:

let client = new AwsClient({
      accessKeyId: ***,
      secretAccessKey: ***!,
    });

let baseUrl =  `https://${accountId}.r2.cloudflarestorage.com`

client
      .fetch(`${baseUrl}/file.txt`, {
        method: 'put',
        body: 'test',
      })

I don't use crypto anywhere in my code even installing crypto doesn't help npm i crypto

Where are you running this? As the README says, this is "for environments that support fetch and SubtleCrypto"

in a Nodejs app which supports fetch

Not sure what's wrong with your env – it's defined for me:

$ node
Welcome to Node.js v20.11.0.
Type ".help" for more information.

'object'

HI I tried adding const crypto = require('crypto'); to the top of the code then it works. I am day1 on nodejs using fedora with node output:

$ node
Welcome to Node.js v18.18.2.
Type ".help" for more information.
> typeof crypto
'object'

May it wouldbe of help.

I tried adding const crypto = require('crypto');

this wo'nt work here because aws4fetch is an external package and we cannot modify its code base

@its-dibo , try adding the Vercel Edge Runtime Polyfill (https://edge-runtime.vercel.app/packages/ponyfill) package:

pnpm add @edge-runtime/ponyfill

then to use it:

import { crypto } from '@edge-runtime/ponyfill'

In case anyone is having this problem running Nuxt locally, you can create a plugin as follows:

export default defineNuxtPlugin(() => {
  const config = useRuntimeConfig();

  if (process.server && config.public.env.toLocaleLowerCase() !== 'prod') {
    const crypto = require('crypto');
    global.crypto = crypto;
  }
})

I am experiencing the same issue on both my local node.js environment and also when deploying on google cloud functions:

Simply adding const crypto = require('crypto'); to the beginning of aws4fetch.cjs.js fixes the problem on my local environment. But I can't do this when deploying to GCF. Could this one line be added as per aws4.js ?
