makedecorator

makedecorator-js

Wraps a function-wrapping function and returns an ES7 decorator capable of decorating an ES6 class method.

Installation

npm install --save makedecorator

Why?

ES7 Decorators employ the same function signature as Object.defineProperty, function(obj, prop, descriptor). You probably don't need to be concerned about that in most cases where you'd simply like to wrap a class method with an existing function.

Example

var makeDecorator = require('makedecorator')

function yell(fn) {
  return function() {
    return fn.apply(this, arguments) + '!';
  };
};

let yellDecorator = makeDecorator(yell);


// Use with function.
function greet() {
  return 'Hello';
}

yellDecorator(greet)();
// returns 'Hello!'


// Declarative use in class design.
class MyClass {
  @yellDecorator
  greet() {
    return 'Hello';
  }
}

let instance = new MyClass();
instance.greet();
// returns 'Hello!'
