`resolveObjectURL` from `node:buffer` not supported in Deno

[kevgeoleo]

Version: Deno 2.5.3

Hi,

I would like to report a behavior I observed when running the following code snippet:

import { resolveObjectURL } from 'node:buffer'

Running this gives the following error:

PS C:\Users\Kevin\Downloads\a\29_09_2025> deno run 12322_toreport.js
error: Uncaught SyntaxError: The requested module 'node:buffer' does not provide an export named 'resolveObjectURL'
import { resolveObjectURL } from 'node:buffer'
         ^
    at <anonymous> (file:///C:/Users/Kevin/Downloads/a/29_09_2025/12322_toreport.js:5:10)

This module works in NodeJS. The Deno compatibility documentation also mentions that it supports node:buffer (https://docs.deno.com/api/node/#data-%26-streams)

I'd like to work on this issue if it's still available.
This looks like a straightforward addition to the node:buffer polyfill, and I’m happy to prepare a PR for implementing resolveObjectURL along with tests.

Could you please assign this to me?
