# mkNodePackage

A helper flake for building Node.js package easily with Nix.

## Why?

Writing derivations for Nix could be very difficult, and this flake tries to hide all the details and allow you to only use commands from Node ecosystem to build a derivation.

## Usage example

### Build a derivation and save it in `XDG_DATA_HOME`

```nix

{ pkgs, config, inputs, system, ... }:

let xdg = config.xdg;

in {

  # Prettier plugin

  home.file = let

    prettierPluginDir = "${xdg.dataHome}/prettier/node_modules";

  in {

    "${prettierPluginDir}/@prettier/plugin-pug" = let 

        version = "743f5aafa11d161537bbcd614fe5af81944a8d2f";

    in{

      source = (inputs.mkNodePackage.lib.${system}.mkNodePackage {

        pname = "prettier-plugin-pug";

        inherit version;

        src = pkgs.fetchFromGitHub {

          owner = "winston0410";

          repo = "plugin-pug";

          rev = version;

          sha256 = "sha256-SUH94XnD0a0JX3SQQmHB9SWnS7oVP9BiBcS9a7o4wm0=";

        };

        buildPhase = ''

        npm run build

        '';

        

        installPhase = ''

        mkdir -p $out

        cp -r dist $out

        '';

      });

    };

  };

}

```

## API Reference

This flakes provide there following functions:

### `lib.${system}.mkNodePackage`

- Auto-detect package manager(`npm`, `yarn`) used in the target project, and build the project.

- Same type signature with `stdenv.mkDerivation`, yet [most are managed](https://github.com/winston0410/mkNodeModule/blob/5c1f2bf09fbce0b4c675b5e6a5fd27c84f52159e/lib.nix#L98)

### `lib.${system}.mkNodeModule`

- Auto-detect package manager used in the target project, and build the `node_modules`.

- Only accpet [a fetcher as `src`](https://github.com/winston0410/mkNodeModule/blob/5c1f2bf09fbce0b4c675b5e6a5fd27c84f52159e/lib.nix#L88)

### `lib.${system}.mkNpmPackage`

- Build the project for project using `npm`.

- Same type signature with `lib.${system}.mkNodePackage`.

### `lib.${system}.mkNpmModule`

- Build `node_modules` for project using `npm`. Use `npmlock2nix` under the hood.

- Same type signature with `lib.${system}.mkNodePackage`.

### `lib.${system}.mkYarnPackage`

- Build the project for project using `yarn`.

- Same type signature with `lib.${system}.mkNodePackage`.

### `lib.${system}.mkYarnModule`

- Build `node_modules` for project using `yarn`. Use `yarn2nix` under the hood.

- Same type signature with `lib.${system}.mkNodePackage`.
