Installation

yarn add -D @adrianbrs/darmogen
# or
npm install @adrianbrs/darmogen --save-dev

Usage

1. Create darmogen.js file in the project root with Darmogen options.
2. Execute yarn darmogen or npx darmogen to generate models on the output path.

Examples

Options file example

darmogen.js

const { kebab } = require("@adrianbrs/darmogen");

module.exports = {
  parser: {
    aliases: {
      src: "{cwd}",
    },
    cwd: "./src",
    root: "../",
    ext: ".entity.ts",
  },
  generator: {
    out: "/home/adrian/Projetos/DartProject/lib/modules/api",
    imports: ["model-base.dart"],
    formatters: {
      name: (name) => name,
      filename: (name) => kebab(name).toLowerCase() + ".model.dart",
    },
  },
};

Model output example

user.model.dart

import '../model-base.dart';
import '../global-roles/global-role.model.dart';
import '../roles/role.model.dart';
import '../friendship/friendship.model.dart';

class User extends Model {
  String name;
  String email;
  String username;
  String avatar;
  List<Role> roles;
  List<Friendship> sentFriendships;
  List<Friendship> receivedFriendships;
  dynamic status;
  GlobalRole globalRole;
  DateTime lastLoginDate;
  String id;
  DateTime createdAt;
  DateTime updatedAt;

  User(
      {String id,
      this.name,
      this.email,
      this.username,
      this.avatar,
      this.roles,
      this.sentFriendships,
      this.receivedFriendships,
      this.status,
      this.globalRole,
      this.lastLoginDate,
      this.createdAt,
      this.updatedAt})
      : super(id);

  @override
  Map<String, dynamic> toJson() => {
        'name': name,
        'email': email,
        'username': username,
        'avatar': avatar,
        'roles': roles?.map((role) => role.toJson())?.toList(),
        'sentFriendships':
            sentFriendships?.map((friendship) => friendship.toJson())?.toList(),
        'receivedFriendships': receivedFriendships
            ?.map((friendship) => friendship.toJson())
            ?.toList(),
        'status': status,
        'globalRole': globalRole?.toJson(),
        'lastLoginDate': lastLoginDate?.toIso8601String(),
        'id': id,
        'createdAt': createdAt?.toIso8601String(),
        'updatedAt': updatedAt?.toIso8601String(),
      };

  factory User.fromJson(Map<String, dynamic> json) {
    if (json == null) return null;
    return User(
        name: json['name'],
        email: json['email'],
        username: json['username'],
        avatar: json['avatar'],
        roles: (json['roles'] as List<dynamic>)
            ?.map((data) => Role.fromJson(data)),
        sentFriendships: (json['sentFriendships'] as List<dynamic>)
            ?.map((data) => Friendship.fromJson(data)),
        receivedFriendships: (json['receivedFriendships'] as List<dynamic>)
            ?.map((data) => Friendship.fromJson(data)),
        status: json['status'],
        globalRole: GlobalRole.fromJson(json['globalRole']),
        lastLoginDate: DateTime.tryParse(json['lastLoginDate'] ?? ''),
        id: json['id'],
        createdAt: DateTime.tryParse(json['createdAt'] ?? ''),
        updatedAt: DateTime.tryParse(json['updatedAt'] ?? ''));
  }
}

Model base example

model-base.dart

import 'dart:convert';

var jsonEncoder = JsonEncoder.withIndent('  ');

abstract class Model {
  String id;

  Model(this.id);

  Map<String, dynamic> toJson();

  String toString() {
    return "$runtimeType ${jsonEncoder.convert(this.toJson())}";
  }
}
