React Native 功能开关服务

Expo 和 React Native 生态系统中可用的功能开关服务概述。

功能开关（也称为功能门控）是一种远程启用和禁用功能的机制。它们是一种安全地向应用用户推出新功能的方法，无需部署额外的代码。你可以使用它们进行生产环境测试、A/B 测试，或发布新的应用功能（例如 UI 元素）。

¥A feature flag (also known as a feature gate) is a mechanism that enables and disables features remotely. They are a safe way to rollout new features to your app users without deploying additional code. You can use them for testing in production, A/B testing, or to ship new app features such as UI elements.

功能标志服务

¥Feature flag services

以下库为功能标记功能提供强大的支持，并与使用 持续的原生生成 (CNG) 和 配置插件 的 Expo 应用提供开箱即用的兼容性，从而实现与你的应用的无缝集成。

¥The following libraries provide robust support for feature flag functionality and out-of-the-box compatibility with Expo apps using Continuous Native Generation (CNG) and config plugins for seamless integration in your app.

Posthog

PostHog 是一个开源产品分析平台，提供全面的功能标记功能以及分析、会话记录和 A/B 测试。它支持实时功能切换、用户细分以及即时回滚功能，对于希望在单一平台上进行分析和功能管理的团队来说，它是一个绝佳的选择。它包含内置的 A/B 测试和多变量测试功能，允许你直接通过功能开关运行实验，同时收集有关功能采用率和性能指标的详细分析数据。该服务还支持引导标志，以消除加载状态并提升用户体验。

¥PostHog is an open-source product analytics platform that provides comprehensive feature flagging capabilities alongside analytics, session recordings, and A/B testing. It supports real-time feature toggles with user segmentation and the ability to roll back features instantly, making it an excellent choice for teams that want analytics and feature management in a single platform. It includes built-in A/B testing and multivariate testing functionality, allowing you to run experiments directly through feature flags while collecting detailed analytics on feature adoption and performance metrics. The service also supports bootstrap flags to eliminate loading states and improve user experience.

Statsig

Statsig 是一个功能管理平台，专为数据驱动的产品开发而设计，它提供高级统计分析、逐步推出和复杂的定位功能，并内置功能发布的指标和性能监控。该平台为 React Native 和 Expo 提供了强大的 SDK，具有自动事件日志记录和动态配置功能，尤其适合专注于严谨实验和数据驱动决策的团队。

¥Statsig is a feature management platform designed for data-driven product development that provides advanced statistical analysis, gradual rollouts, and sophisticated targeting capabilities with built-in metrics and performance monitoring for feature releases. The platform offers a robust SDK for React Native and Expo, with automatic event logging and dynamic configurations, making it particularly well-suited for teams focused on rigorous experimentation and data-driven decision-making.

LaunchDarkly

LaunchDarkly 是一个企业级功能管理平台，它支持即时功能切换和定向部署，并具备全面的仪表板控制、高级用户定位功能以及提供实时标志更新的强大实验工具。SDK 包含一些高级功能，例如用于 React 集成的钩子、上下文识别和修改、全面的日志记录、开发工作流中的多环境支持、用于处理敏感数据的私有属性以及用于增强安全性和性能的中继代理配置。

¥LaunchDarkly is an enterprise-grade feature management platform that enables instant feature toggles and targeted rollouts with comprehensive dashboard controls, advanced user targeting, and robust experimentation tools that provide real-time flag updates. The SDK includes advanced features such as hooks for React integration, context identification and modification, comprehensive logging, support for multiple environments in development workflows, private attributes for handling sensitive data, and relay proxy configuration for enhanced security and performance.

Firebase 远程配置

¥Firebase Remote Config

Firebase 远程配置 是一项云服务，允许你更改应用的外观和功能，而无需更新应用。远程配置值通过 Firebase 控制台进行管理，并通过 JavaScript API 访问，这使你可以完全控制这些值何时以及如何影响你的应用。该服务支持基于用户属性、应用版本、自定义属性和实时更新的条件定位。

¥Firebase Remote Config is a cloud service allows you to change the appearance and functionality of your app without requiring an app update. Remote Config values are managed through the Firebase console and accessed via a JavaScript API, which gives you full control over when and how these values affect your app. The service supports conditional targeting based on user properties, app versions, custom attributes and real-time updates.
