| summary | Here's a summary of the website content regarding Async Hooks, BufferPath, Performance Hooks:
This documentation details Node.js’s asynchronous I/O utilities, primarily focused on providing more granular control and performance metrics for asynchronous operations. Async Hooks allow you to intercept and customize the execution of callback functions associated with Node.js’s built-in I/O modules (like `fs`, `net`, `tls`). You can register hooks to track progress, handle errors, and even modify the behavior of these operations.
BufferPath is a mechanism for associating buffers with their underlying file streams, allowing for efficient tracking of buffer usage and management of the file stream itself. It aims to optimize data transfer and avoid unnecessary memory copies.
Performance Hooks provide a structured way to measure the performance of asynchronous I/O operations directly within the hook callbacks. This allows for detailed profiling and pinpointing of bottlenecks in your code. These hooks help to minimize performance overhead and improve the efficiency of asynchronous tasks.
In essence, the combined use of these tools allows for deep customization and performance tuning of asynchronous Node.js applications, particularly around file system and network operations. |
