sixth-sense
This library gives functions a sixth sense. It allows them to know when they're called, when they throw, and can even modify return values (EVEN after the function has executed).
Installation
npm install sixth-sense
Usage
import { aware } from "sixth-sense";
const add = aware(function (a, b) {
// Listen for if the function throws
this.onThrow(error => {
this.return(-1);
});
// You can add as many .onThrow listeners as you want
this.onThrow(error => {
console.log(error);
});
// Listen for when the function has executed
// Again, you can add as many .after listeners as you want
this.after(result => {
if (result === 30) {
this.return(99);
}
});
// Business logic below
if (Math.random() > 0.5) {
throw new Error("Math exists");
}
return a + b;
});
