JS-Proxy

A multithreaded man-in-the-middle proxy which captures JavaScript on the fly and lets you modify it using a callback.

Installation

npm install js-proxy

The callback function is called for each node returned by falafel

var proxy = require('js-proxy');
 
var options = {};
options.port = 9003;
options.threads = 3;
options.preprocess = function(input){
     // add in your preprocessing logic here
     return input;
};
options.postprocess = function(input){
     // add in your postprocessing logic here
     return input;
};
options.instrument = function(node) {
    if(node.type == "Program") {
   	node.update("'use strict;';\n" + node.source());
    }
}
 
proxy.start(options);
