vmod


Virtual module for node.js - vmod

- Runs in different script context than your current script;
- Executes a string of code in require-like environment;
- Allows you to override globals of the sandbox environment;
- Returns module.exports output;
- Throws errors that can be caught in your current context;

Known limitations:
- console.log, console.warn, console.error, etc. output not visible;
- Modifications to prototypes of some globals not visible in the vmod context;
- Only CommonJS modules supported;

Installation
------------
``bash
$ npm install vmod --save
`

const vmod = require('vmod');

console.log(
vmod(
'module.exports = () => "yay!";'

`js
/*
./_test-file.js:
