nodejs/node-addon-api

• Native Addon Frameworks - Provides a framework for building high-performance native addons for Node.js by wrapping native interfaces into object-oriented structures.
• Node.js Native Addons - Builds high-performance compiled extensions for Node.js using C++ to execute intensive logic.
• Asynchronous Task Execution - Offloads computationally expensive operations to background threads and returns results to the main event loop.
• C-API Wrappers - Provides a type-safe object-oriented interface that simplifies interaction with low-level native APIs.
• Cross-Language Data Exchange - Facilitates seamless data exchange and translation between native C++ primitives and JavaScript objects.
• Native C-JavaScript Bridges - Provides abstractions for managing memory, data conversion, and task execution across the C++ and JavaScript boundary.
• Foreign Function Interfaces - Enables the execution of compiled native code within a managed runtime by mapping data types and function calls.
• Node-API Bindings - Provides a header-only object-oriented interface for building native Node.js addons using the Node-API.
• Native Memory Lifecycle Management - Tracks and manages the memory and lifecycle of native C++ objects and JavaScript references to prevent leaks.
• Native Addon Abstraction Frameworks - Provides a toolkit for exposing high-performance C++ logic and data structures to the JavaScript runtime.
• Native Data Marshallers - Translates between native primitives and script-based data structures to facilitate seamless and reliable information exchange.
• Script-to-Native Type Mappings - Translates between native primitives and script-based objects to facilitate seamless data exchange across the language boundary.
• Thread Pool Offloading - Offloads intensive computations to background threads and returns results to the main event loop using non-blocking worker patterns.
• Reference Counting - Tracks the lifecycle of native and script-side objects to ensure resources are reclaimed automatically when they are no longer in use.
• Native Logic Integrations - Exposes native code and data structures through a standard interface to allow high-performance execution of compiled logic.
• Error-to-Exception Mappings - Maps internal C++ errors to standard JavaScript exceptions for robust failure management.
• JavaScript Data Types and Structures - Provides a type-safe interface for manipulating JavaScript primitives, objects, and buffers within native C++ code.
• JavaScript Exception Handling - Translates native exceptions into JavaScript errors and provides mechanisms to manage error states across the language boundary.
• JavaScript Object References - Tracks and releases native references to JavaScript objects to ensure memory is reclaimed correctly.
• Native Class Wrappers - Wraps native class methods into accessible objects so that developers can instantiate and manipulate complex logic directly from within the runtime.
• Native Object Wrapping - Exposes native class instances to the runtime so that developers can create, modify, and pass complex data structures.
• Native Object Finalizers - Hooks into the garbage collection process to trigger cleanup routines for native resources once their corresponding script-side objects are destroyed.
• V8 Object Wrapping - Wraps native C++ classes as JavaScript objects with integrated lifecycle and memory management.
• Object Lifetime Management - Manages the lifecycle of native objects and memory buffers to ensure they are garbage collected when no longer referenced.
• Native-to-JS Thread Dispatching - Invokes JavaScript functions from background threads to ensure reliable data exchange between native execution environments and the main event loop.
• Native Error Code Converters - Maps native exceptions and error states to standard JavaScript error types for consistent failure handling.
• Module Lifecycle Management - Hooks into the module lifecycle to perform cleanup, track module data, and manage resources across multiple threads or execution contexts.
• Thread and Process Synchronization - Coordinates communication between background native threads and the main execution thread to prevent data corruption.
• Native Error Reporters - Maps native exceptions to standard script error types to ensure consistent diagnostic reporting and stack trace propagation.
• Native Panic-to-Exception Bridges - Converts internal native errors into standard script exceptions to prevent runtime crashes and provide meaningful feedback.

该项目为 Node-API 提供了一个仅包含头文件的 C++ 包装器，作为构建 Node.js 高性能原生插件的框架。它充当 C++ 与 JavaScript 之间的桥梁，提供了一个面向对象的接口，简化了编译扩展的创建，同时管理了语言边界的复杂性。
