Supported Typescript workflow?

[kylegentle]

I'm trying to figure out how to build and/or run a Typescript project using dream2nix. I've created a minimal example at kylegentle/ts-dream-example, with some more context in the README; let me know if you want me to bring more of that context into the issue here.

See this PR. you don't need to use npx, as typescript exists in nixpkgs as nixpkgs.nodePackages.typescript. As for ts-node, add it as a shell hook from your built package. run nix develop .#ts-dream-example https://github.com/kylegentle/ts-dream-example/pull/1

Any idea what might be wrong in this typescript package I'm trying to make for work: https://github.com/input-output-hk/cardano-js-sdk

what I've got so more:

{
  inputs = {
    dream2nix.url = "github:nix-community/dream2nix";
    src.url = "github:input-output-hk/cardano-js-sdk/0.2.0";
    src.flake = false;
  };

  outputs = {
    self,
    dream2nix,
    src,
    nixpkgs,
  } @ inp: let
    dream2nix = inp.dream2nix.lib2.init {
      systems = ["x86_64-linux"];
      config.projectRoot = ./.;
    };
  in
    (dream2nix.makeFlakeOutputs {
      source = src;
      packageOverrides = {
        "@cardano-sdk/cip2".add-inputs.buildInputs = with nixpkgs.legacyPackages.x86_64-linux;
        self: self ++ [ nodePackages.typescript ];
      };
    });
}

And the error:
