Wraps a function-wrapping function and returns an ES7 decorator capable of decorating an ES6 class method.
npm install --save makedecorator
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.
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!'To compile:
npm run compile
