Repair

Repair broken instances of native JS constructors, making instanceof work! Running code in different VMs will break the instance's reference. Simply pass an instance or collection of instances to repair and instanceof checks will run again. Although this sounds silly, consider a configuration with multiple RegExp instances or dependencies that assume instanceof checks to work.

Install

npm install --save repair

Example

var repair = require('repair')
  , vm = require('vm')
  , config = {};

vm.createContext(config);
vm.runInContext('date=new Date', config);

assert.equal(config.date instanceof Date, true, 'Different instance');
assert.equal(repair(config.date) instanceof Date, true);
