Когда выбирают GraphQL

• используется микросервисная архитектура и REST стал слишком сложным
• нужна экономия на объеме запросов
• есть желание отвязать фронт от бека для ускорения и повышения качества разработки
• хочется получить всегда актуальную документацию на халяву

Итоги

• Один раз описать сущности
• Не париться за документацию
• Один API для всех
• Возможность оптимизации запросов к API
• Меньше времени на задачи и коммуникации
• Избавление от тысяч ViewModel
