javascript-proxy-aop v0.0.2

javascript-proxy-aop

Uses ES6 Proxy to instrument JS in an (unfortunately too verbose) aspect-oriented way

Install

$ npm install --save javascript-proxy-aop

Usage

const javascriptProxyAop = require('javascript-proxy-aop');

// pubSub may be any object that supports trigger
const instrument = javascriptProxyAop(pubSub);

const obj = instrument({
	method: function() {},
	anotherMethod: function fooBar() {}
});

obj.method(['hello', 'world']);
// => pubSub.on('onBeforeMethod', method, args) is called
//		=> method: 'anonymous<method>'
//		=> args: [['hello', 'world']]
// => pubSub.on('onAfterMethod', method, args) is called
//		=> method: 'anonymous<method>'
//		=> args: [['hello', 'world']]
//		=> result: undefined

obj.anotherMethod(); // method is 'fooBar'

TODO

• enable to instrument functions directly
