Nix support for Deno

Usage

  • lockfile -> ./lock.json
  • import map -> ./import_map.json
  • entrypoint -> ./mod.ts

Update lock.json for caching

deno cache --import-map=./import_map.json --lock lock.json --lock-write ./mod.ts

Setup for nix flake (example)

{
  inputs.deno2nix.url = "github:SnO2WMaN/deno2nix";
  inputs.devshell.url = "github:numtide/devshell";

  outputs = {
    deno2nix,
    flake-utils,
    ...
  }:
    flake-utils.lib.eachDefaultSystem (system: let
      pkgs = import nixpkgs {
        inherit system;
        overlays = [
          devshell.overlay
          deno2nix.overlay
        ];
      };
    in {
      packages.executable = pkgs.deno2nix.mkExecutable {
        name = "example";
        version = "0.1.0";
        src = self;
        lockfile = ./lock.json;
        importmap = ./import_map.json;
        entrypoint = ./mod.ts;
      };
    });
}
