sandboxed-module-loader

Sandbox loading of modules. Useful in unit testing to give each test an unique copy of each dependency.

Install

$ npm install sandboxed-module-loader

Usage

const loader = require('sandboxed-module-loader');
 
loader(/\/main-file.js$/, {
  verbose: 1,
  sandboxExternal: false
});

API

The sandboxed-module-loader is initialized with a main file. All dependencies of this file will be sandboxed. This means that they will not share any modules. If the same module is required, each sandbox will have a separate instance of the module.

loader(path, options)

path

Regex specifying a main file. All dependencies of this file will be sandboxed.

options.verbose

Number specifying verbosity level. Used for debugging.

0: Silent
1: Info
2: Verbose

options.sandboxExternal

Boolean, specifying if only local files should be sandboxed. If set to false, external modules are shared between sandboxes.

loader.reset()

Reset the module loader to the original.
