bootstrapper 0.2.0

Bootstrapper is a package to initialize multiple config concurrently by grouping them.

Bootstrapper

Bootstrapper is a Dart package that enables you to initialize multiple configuration processes concurrently by organizing them into prioritized groups. Suitable for application startup sequences, dependency initialization, and scenarios where you need controlled concurrent execution.

Usage

import 'package:bootstrapper/bootstrapper.dart';

class DatabaseConfig implements Bootstrappable<String> {
  DatabaseConfig(this.groupId);

  @override
  final int groupId;

  @override
  Future<void> initialize(String property) async {
    print('DatabaseConfig($groupId) started with $property environment');

    await Future.delayed(const Duration(seconds: 1));

    print('DatabaseConfig($groupId) completed');
  }
}

class CacheConfig implements Bootstrappable<String> {
  CacheConfig(this.groupId);

  @override
  final int groupId;

  @override
  Future<void> initialize(String property) async {
    print('CacheConfig($groupId) started with $property environment');

    await Future.delayed(const Duration(seconds: 2));

    print('CacheConfig($groupId) completed');
  }
}

class ApiConfig implements Bootstrappable<String> {
  ApiConfig(this.groupId);

  @override
  final int groupId;

  @override
  Future<void> initialize(String property) async {
    print('ApiConfig($groupId) started with $property environment');

    await Future.delayed(const Duration(seconds: 3));

    print('ApiConfig($groupId) completed');
  }
}

Future<void> main() async {
  final bootstrapper = Bootstrapper<String>(
    property: 'development',
    bootstrappables: [
      // Group 0: High priority - Database and Cache run concurrently
      DatabaseConfig(0),
      CacheConfig(0),
      // Group 1: Lower priority - API runs after Group 0 completes
      ApiConfig(1),
    ],
  );

  print('Starting application initialization...');

  await bootstrapper.initialize();

  print('Application ready!');
}
