monkey-dont

A monkey-patch to prevent monkey-patching.

This is a first try, largely un-tested, and probably buggy. Use at your own risk.

It works by rewriting Node's internal _load method to modify modules' exports in one of three ways:

1. clone - Causes require to return a deep copy of module.exports.
2. freeze - Causes require to recursively apply Object.freeze on module.exports before returning it.
3. uncache - Causes require to delete the module from require.cache and re-load it the module's main .js file.

To deep-clone every module:
``js
require('monkey-dont').monkey('clone');
`

To deep-freeze every module:
`js
require('monkey-dont').monkey('freeze');
`

To un-cache every module, except built-ins, which can't be un-cached:
`js
require('monkey-dont').monkey('uncache');
`

To uncache all modules by default but freeze the built-ins:
`js
require('monkey-dont').monkey({
all: 'uncache',
builtin: 'freeze',
});
`

To clone fs and path, freeze the remaining built-ins, and un-cache the remaining non-built-ins:
`js
require('monkey-dont').monkey({
all: 'uncache',
builtin: 'freeze',
byname: {
'fs': 'clone',
'path': 'clone',
},
});
`

To do all the above, except freeze the module foo instead of uncaching it:
`js
require('monkey-dont').monkey({
all: 'uncache',
builtin: 'freeze',
byname: {
'fs': 'clone',
'path': 'clone',
'foo': 'freeze',
},
});
`

To make the patch removable, keep the monkey-dont export instead of immediately calling monkey on it. Then call its unmonkey method to remove the patch.

(Note: This can't retroactively undo any cloning, freezing, and uncaching already done; it just returns require to its normal behavior. Future requires will return un-cloned, cached originals, but already-frozen modules will remain frozen on future requires.)
`js
const md = require('monkey-dont');
md.monkey({
// ...snip...
});
// ...snip...
md.unmonkey();
