介绍Trunk-Based Development工作流及Feature Flag机制，帮助团队实现持续集成和安全发布。
Introducing Trunk-Based Development workflow and Feature Flag mechanisms for continuous integration and safe releases.
为什么选择Trunk-Based相比Git Flow的复杂分支模型，Trunk-Based Development提倡所有开发者频繁地向主分支（trunk/main）提交小批量变更。这种方式减少了合并冲突、加速了代码审查、简化了CI/CD流水线。Feature Flag实践Feature Flag（功能开关）允许在不发布新版本的情况下控制功能的可见性。开发者可以将未完成的功能合并到主分支，通过Feature Flag控制其在生产环境的暴露范围。常用工具：LaunchDarkly、Unleash、自建配置中心。实施要点短生命周期分支（不超过1天）；强制代码审查（但保持小粒度）；全面的自动化测试覆盖；Feature Flag的生命周期管理（及时清理过期Flag）。
Why Trunk-BasedCompared to Git Flow's complex branching model, Trunk-Based Development advocates frequent small commits to the main branch (trunk/main). This approach reduces merge conflicts, accelerates code reviews, and simplifies CI/CD pipelines.Feature Flag PracticesFeature Flags allow controlling feature visibility without deploying new versions. Developers can merge incomplete features to main, controlling production exposure through flags. Popular tools: LaunchDarkly, Unleash, or custom configuration centers.Implementation TipsShort-lived branches (no longer than 1 day); mandatory code reviews (but keep them small); comprehensive automated test coverage; Feature Flag lifecycle management (promptly clean up expired flags).
