Is there any way to generate a development shell for a package that requires build-time dependency wrapping/patching?

Context:

I'm trying to create a development environment for a basic NextJS project. NextJS requires the sharp library, which has an implicit dependency on a specific version of libvips.

There is an example of patching a package dependency in the Wrapping or patching the code or any of its dependencies section of the README. This approach works to generate a package; here's my override.nix:

{ pkgs ? import <nixpkgs> {
  inherit system;
}, system ? builtins.currentSystem }:

let
  name = "my-nextjs-package";
  vipsVersion = "8.10.0";
  nodePackages = import ./default.nix {
    inherit pkgs system;
  };
  sharpVips = builtins.fetchurl {
    url = "https://github.com/lovell/sharp-libvips/releases/download/v${vipsVersion}/libvips-${vipsVersion}-linux-x64.tar.gz";
    sha256 = "0a6digd1bmb96zzyqahgmlv1r0gbb2dj1n37plm6xga3fmf1xiwi";
  };
  vendorDir = "$out/lib/node_modules/${name}/node_modules/sharp/vendor/${vipsVersion}";
in
nodePackages // {
  package = nodePackages.package.override {
    preRebuild = ''
      mkdir -p ${vendorDir}
      tar -xvf ${sharpVips} -C ${vendorDir}
    '';
  };
}

How can I do the same thing, but for a shell environment? #44 is closely related, although I see it was closed some time ago.
