turbopack equivalent of webpack ProvidePlugin for Buffer?

[bitgoAaron]

Summary

Is there an equivalent way of providing a global override for Buffer, similar to how webpack supports this:

   new webpack.ProvidePlugin({
      Buffer: ['buffer', 'Buffer'],
      process: 'process/browser',
    }),

I'm finding that the Buffer used by turbopack is missing a couple key functions, like 'readBigUInt64LE' and others. These are all implemented by the https://www.npmjs.com/package/buffer package for using Buffer in the browser.

I have already tried this:

turbopack: { 
  resolveAlias: { 
    buffer: { browser: './node_modules/buffer/index.js' },
    Buffer: { browser: './node_modules/buffer/index.js' }
  }
}

which seems to include the functions on the Buffer prototype if I manually import that myself, but those functions are not available on transitive dependencies, so I end up with a runtime error
"buffer.readBigUInt64LE is not a function" when used in my application. Any help or pointers would be appreciated.

Hi, this is the repository for Turborepo, not Turbopack, so I'll transfer to the Next.js repo where the Turbopack team is currently operating.
