Readme
Async 'will' and 'did' hooks for any methods.
npm i async-hooks
'use strict';
const hooks = require('async-hooks');
// Define your class
class MyClass {
constructor() {
hooks(this);
}
method(arg1, arg2) {
return Promise.resolve(arg1 + arg2);
}
}
// Instantiate MyClass
const myClass = new MyClass();
// Now you can add hooks to any class methods
myClass.will('method', (arg1, arg2) => {
// ... do something
});
myClass.will('method', (arg1, arg2) => {
// ... do something else
});
myClass.did('method', res => {
// ... do something
return res;
});
myClass.did('method', res => {
// ... do something else
return res;
});
Adds will
and did
methods to the object
. Both will
and did
are lazy methods. So to use auto hooks you still should run it as:
hooks(this, 'method', 'anotherMethod');
Adds will (runs before) hook
function to the method
only if method
exists and it is a function. hook
function will receive all arguments as the original method. If hook
function is async it should return a Promise.
If object has will<Method>
it will be run before all other hooks
Adds did (runs after) hook
function to the method
only if method
exists and it is a function. hook
function will receive a result of the original method or previous hook and should return result or Promise.
If object has did<Method>
it will be run after all other hooks
If object has catch<Method>
it will receive the throws and orginal arguments.
