construct-from-spec

A little helper to construct object from "specifications". Usage example:

var createConstructor = require('construct-from-spec')

var construct = createConstructor(
  'name', // name of the key which is used as a pointer to a function
  true    // if we need to use `new` operator when calling a function
);

var spec = {
  name: 'buffer:Buffer',
  subject: 'hello'
}

var buf = construct(spec) // the same as `new Buffer('hello')`

Where this can be useful? In configuration files, now you can construct entire objects from a JSON object. Please note, that this can lead to security vulnerabilities, cause config author can do an arbitrary code execution.

Installation

% npm install construct-from-spec
