async_hooks: add AsyncResource.bind utility #34574

jasnell · 2020-07-31T02:58:04Z

Creates an internal AsyncResource and binds a function to it,
ensuring that the function is invoked within execution context
in which bind was called.

This is suggested as a solution for #33723 and is a simple utility over what can already be done with AsyncResource.

It would be nice if bind was an instance method so one could easily bind an already created resource and then maybe the static version could just use that internally. 🤔

jasnell · 2020-07-31T03:17:27Z

@devsnek ... updated!
@Qard ... good idea, updated!

What becomes obvious is that this is a very simple utility that wraps something that can already be done but eliminates some boilerplate.

+  }
+
+  static bind(fn, type = fn?.name) {
+    return (new AsyncResource(type || 'bound-anonymous-fn')).bind(fn);


no points will be deducted for using a temporary variable :P

parentheses unnecessary?

Yeah but stylistically I prefer them (more readable in my opinion)

Getting the super duper helpful error...

We really should fix that, it's stopping us from using all the new syntax :( I had a commit somewhere but I have no idea where it went. You could include a commit that patches this with a try/catch:

Some comments, nothing blocking and feel free to ignore:

It might be helpful to set function.length to the same value as the original function. If used together with EventEmitter it's don't care but this API is not limited to this and e.g. a express distinguishes between functions with 3 and 4 arguments.

It may be also helpful to somehow allow to check if a function is bound to an async resource. APMs, OTel plugins,... currently patch EventEmitter to wrap listeners for context passing. If this is done already in user code via this API it's not needed anymore.

Creates an internal AsyncResource and binds a function to it, ensuring that the function is invoked within execution context in which bind was called.

jasnell · 2020-08-04T00:38:58Z

@Flarna ... good suggestions! I've updated to set the length property and added an asyncResource property to the returned function.

The length property should be non enumerable to match behavior of normal functions. The asyncResource property is enumerable and therefore it should be also writable to avoid issues like there: nodejs#30932 (comment) Both properties should be configurable. Refs: nodejs#34574
