deno2nix

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 = {
    self,
    nixpkgs,
    flake-utils,
    ...
  } @ inputs:
    flake-utils.lib.eachDefaultSystem (system: let
      inherit (pkgs) deno2nix;
      pkgs = import nixpkgs {
        inherit system;
        overlays = with inputs; [
          devshell.overlay
          deno2nix.overlay
        ];
      };
    in {
      packages.executable = deno2nix.mkExecutable {
        pname = "example-executable";
        version = "0.1.2";

        src = ./.;
        lockfile = ./lock.json;

        output = "example";
        entrypoint = "./mod.ts";
        importMap = "./import_map.json";
      };
    });
}

deno2nix.mkExecutable

Args

{
  pname,
  version,
  src,
  lockfile,
  output ? pname, # generate binary name
  entrypoint,
  importMap ? null, # ex. "./import_map.json" to $src/${importMap}
  additionalDenoFlags ? "", # ex. "--allow-net"
}
