v2.0 upgrade 'codemod'/quick safe automated code updates

[sambacha]

Upgrading a package to use v2.0 from 1.7, just curious what other safe code transformations you would suggest, so far:

using GritQL for code mod

ImportSha3Js

rule ImportSha3Js {
  find {
    import $x from "@noble/hashes/sha3"
  }
  replace {
    import $x from "@noble/hashes/sha3.js"
  }
}

ImportSha2

rule ImportSha2 {
  find {
    import { sha256, sha512 } from "@noble/hashes"
  }
  replace {
    import { sha256, sha512 } from "@noble/hashes/sha2.js"
  }
}

ImportBlake2

rule ImportBlake2 {
  find {
    import { blake2b, blake2s } from "@noble/hashes"
  }
  replace {
    import { blake2b, blake2s } from "@noble/hashes/blake2.js"
  }
}

ImportLegacy

rule ImportLegacy {
  find {
    import { ripemd160, sha1, md5 } from "@noble/hashes"
  }
  replace {
    import { ripemd160, sha1, md5 } from "@noble/hashes/legacy.js"
  }
}

Uint8Array

Warning

No idea bout' this,

rule DisallowStringInputs {
  find {
    $fn($arg)
  }
  where {
    $fn in {sha256, sha512, sha3_256, sha3_512, blake2b, blake2s, ripemd160, sha1, md5}
    typeof($arg) == "string"
  }
  message "Hash inputs must be Uint8Array, not string. Use utils.utf8ToBytes($arg) first."
}

Using GritQL as Cloudflare uses it for Terraform Provider major version migrations: https://registry.terraform.io/providers/cloudflare/cloudflare/latest/docs/guides/version-5-upgrade#automatic

There are very few changes: we’ve made sure to make upgrade painless.

Those transformations make sense. Maybe also sha256().update(str).digest() (str now also needs utf8tobytes) if you’ve been using streaming version
