Hi all,
I'm trying to "unload" a previously require()d module (specifically,
express) to save memory. So I tried deleting all references to the Module
objects - in require.cache, global.module.children, and the variable that
is assigned the module's exports (var express = require('express')).
However, the object does not seem to be collected by the garbage collector,
the memory consumption stays at a high level. Are there other references to
loaded modules saved somewhere, or could anyone provide hints on unloading
modules?
Ideally, I would like to actually run the module in an extra context - e.g.,
var myScript = vm.createScript('var express = require("express")');
var sandbox = { require:global.require };
myScript.runInNewContext(sandbox);
sandbox=null;
myScript=null;
but even in this case, the memory is not freed.
Any help is greatly appreciated.
Thanks a lot,
Hubert
