内容提要
本书内容涵盖了 Node.js高并发的原理、源码分析以及使用 Node.js开发应用所需要的不同层面的技术实践。具体来讲，本书包括 Node.js异步机制（配以源码分析）、编辑与调试、测试技术、Docker 部署、模块机制、V8 引擎与代码优化、Promise 和 ES6 Generator、LoopBack 开源框架、使用 C++ 编写扩展、JavaScript严格模式、编码规范等内容。在 LoopBack 章节，本书详细介绍了使用此框架开发企业级 Web 应用的步骤，帮助读者迅速掌握使用这个强大框架的诀窍。最后一章详细介绍了编写不同类型的 C++ 模块的知识，并对堆内存管理等内容做了深入探讨。 本书适合所有前端和后端的开发人员阅读。
