@dizmo/functions-deprecated

A decorator to deprecate class methods (and properties): It takes an optional message (or function) and returns the original method, where a [DEPRECATED] Class.method: message text is printed at most once upon invoking the deprecated method (using console.warn).

Usage

Installation

npm install @dizmo/functions-deprecated --save

Require

import { deprecated } from '@dizmo/functions-deprecated';
import { original } from '@dizmo/functions-deprecated';

Example(s)

class MyClass {
    @deprecated
    method1() { ... }

    @deprecated('message')
    method2() { ... }

    @deprecated((self, key) => 'message')
    method3() { ... }
}

..where self instanceof MyClass and key === 'method3'.

const instance = new MyClass();
original(instance.method).bind(instance)();

..where bind(instance) is required!

class MyClass {
    @deprecated
    static method1() { ... }

    @deprecated('message')
    static method2() { ... }

    @deprecated((self, key) => 'message')
    static method3() { ... }
}

..where self === MyClass and key === 'method3'.

original(MyClass.method).bind(MyClass)();

..where bind(MyClass) is required!
