@dizmo/functions-after

Returns a function decorating an original function with a callback, which will be invoked after the execution of the original function. The return value of the original function will be handed over to the after callback as an argument, while the return value of the callback will become the overall result.

Usage

Install

npm install @dizmo/functions-after --save

Require

const { after } = require("@dizmo/functions-after");

Examples

import { after } from "@dizmo/functions-after";

const f1 = (): number => {
    return 1;
};
const f2 = after(f1, (n: number): number => {
    return n + 1;
});
const expect = 2 === f2();

class Class {
    @after.decorator((n: number): number => {
        return n + 1;
    })
    public method(): number {
        return 1;
    }
}
const expect = 2 === new Class().method();
