vkbottle is an asynchronous Python framework for building VK (VKontakte) bots and interacting with the VK API. It provides both high-level abstractions (Bot, User, labelers, rules, middlewares, state dispensers) and low-level API clients with pluggable request/response validation, token rotation, and error handling. The framework is fully async, built on asyncio and aiohttp, and supports long polling, callback API, and dual mode (simultaneous polling and callback). It includes extensive tooling for keyboards, templates, uploaders, markdown-to-VK-format conversion, VKScript generation, event deduplication, and a waiter machine for awaiting future events. The architecture is modular with abstract base classes for nearly every component, enabling custom implementations. The codebase is well-structured with clear separation of concerns, extensive test coverage, and CI/CD pipelines. Deprecated components (LoopWrapper, Blueprints) are clearly marked, and the library is actively maintained with a mature version 4.11.0.
The VK iOS SDK is a library for integrating iOS applications with the VK (VK.com) social network. It provides authentication via OAuth, API request execution with JSON parsing into model objects, and UI components for sharing, authorization, and captcha handling. The SDK features a modular architecture with distinct layers for networking (VKRequest, VKHTTPClient), API method wrappers (VKApi), dynamic object mapping (VKApiObject), and resource management (VKBundle). Key entry points include the VKSdk singleton for session management, VKApi for convenient API calls, and VKAuthorizeController/VKShareDialogController for UI flows. The SDK relies on system frameworks (UIKit, Foundation, WebKit) and includes an example demonstration application. While the codebase shows strong engineering in reusable components like VKRequest and VKApiObject, it exhibits some technical drift through deprecated APIs (UIAlertView) and version discrepancies between documentation and podspec.
