Bootstrapping a node.js project with nix

Use nix-shell to temporarily use node2nix and generate a default.nix file from an existing package.json file.

bash

nix-shell -p nodePackages.node2nix --command "node2nix . > default.nix"

Now we can create a new shell using

bash

nix-shell -A shell

Alternatively, we create a simple shell.nix file which removes the need to pass in -A shell

nix

{ pkgs ? import <nixpkgs> { } }:
let
  nodePackages = import ./default.nix {};
in
  nodePackages.shell
