async-hooks

问题 I'm the author of a Node.js library and I want to use Async Hooks to improve DX. But I'm worried about performance. I've read stories saying that everything is fine, as well as stories where performance was a blocker. In theory, asynchronicity should only happen for IO operations and performance penality should be pretty much ~0. (As IO operations are several orders of magnitude more expensive than running JS code.) But, in practice, does running extra JS on each async call induces a non

问题 I am trying to run test code of Async Hooks from official node api documentation and i am getting error Error: Cannot find module 'async_hooks' in console. I already include const async_hooks = require('async_hooks'); at the top of my script. Here is my code: const async_hooks = require('async_hooks'); // Return the ID of the current execution context. const eid = async_hooks.executionAsyncId(); // Return the ID of the handle responsible for triggering the callback of the // current execution
