Делаем модуль на C++ для приложения React Native

Я не планировал переписывать приложение React Native на C++ . Большая часть приложения прекрасно работала на TypeScript: экраны, формы, валидация, навигация, логика продукта — все это находилось именно там, где нужно. Проблема была более узкой и специфичной: нам нужно было, чтобы один фрагмент логики работал с производительностью, близкой к нативной, оставался общим для Android и iOS и при этом был доступен из JavaScript через обычный типизированный API. Поначалу все звучало слишком просто. Написать интерфейс на TypeScript, позволить Codegen генерировать контракты, перенести основную логику на C++, зарегистрировать модуль на обеих платформах и использовать его из React Native как любой другой модуль. Спойлер: да, это работает. Чистый модуль Turbo Native на C++ действительно может дать вам одну реализацию для Android и iOS, типизированную границу через Codegen, меньшие накладные расходы, чем у старого Bridge, и удобный способ повторного использования существующего кода на C или C++ внутри приложения React Native. Спойлер номер два: код на C++ — это не самая сложная часть. Самое сложное начинается вокруг: CMake, NDK, Xcode, Objective-C++, время жизни среды выполнения JSI, регистрация модулей, границы потоков, владение памятью, обработка ошибок, сборки Expo, сторонние библиотеки и вопрос, который никто не хочет задавать слишком поздно — действительно ли этот модуль должен быть нативным? В этой статье я подробно расскажу о создании C++ Turbo Native модуля для React Native: где этот подход полезен, где он добавляет скрытые затраты на поддержку, чем отличается регистрация для Android и iOS, почему важна обертка TypeScript и почему сам TurboModule должен оставаться «тонким».

React Native. Часть 1: архитектура, производительность и варианты использования

React Native прошел путь от решения с фундаментальными архитектурными ограничениями до платформы с современным, производительным ядром. В этой статье мы разберем, как работала старая архитектура на основе Bridge , как ее заменили JSI, Fabric и Hermes , и в каких случаях React Native - оптимальный выбор для проекта. Старая архитектура с Bridge В основе этой архитектуры лежат асинхронный Bridge. Нативный код и JavaScript работали в отдельных потоках. Общение между ними происходило через Bridge, который передавал сообщения в формате JSON.
