Provide context to the keyResolver function (target and propertyName) about utils-decorators HOT 5 CLOSED

Hi @scaljeri, I am currently on a family vacation. I will take a look as soon as I will return (2 weeks approximately)

from utils-decorators.

Hi @scaljeri, if I understand your intention correctly, you are trying to provide the keyResolver with some extra data (context).
If you wish to have access to the context you could pass a method name (is more info documentation).

Here is an example (taken from a unit test) https://github.com/vlio20/utils-decorators/blob/master/src/memoize/memoize.spec.ts#L126

from utils-decorators.

Hi @vlio20 In that code example. foo and fooWithInnerMapper are both part of the same class. So yes, inside foo you can probably do what I want (not complete sure). But if you look at my Stackblitz, I would like to create a generic decorator. But maybe I missed the point, so maybe you can modify my stackblitz and demonstrate how to do what I'm looking for.

I have to say that I do not fully understand your proposal. If you want to ignore specific arguments why not just do something like that:

keyResolver: (a: number, b: number, c: numer) => `${a}_${b}`

In this example, I am ignoring a.

In my demo I have the following

import { Cached } from './cache-decorator';
import { CachedParamIgnore } from './cache-param-ignore';

class Example3 {
    @Cached({ expirationTimeMs: 4000 })
    fibo(@CachedParamIgnore() n: number, x?: number): number {
        console.log('calculate for ', n);

        if (n < 2) return 1;

       return this.fibo(n - 1) + this.fibo(n - 2);
   }
}

const test = new Example3();

test.fibo(5, 9));
test.fibo(5, 9));

file

Inside that Cached decorator (file) I have that keyResolver function. It doesn't know anything about Example3 or which parameter you want to ignore. Hope this makes more sense :)
