Do stuff with Node.js's native JavaScript modules
Dear Beloved User,
I feel compelled to give you a word of warning if you are considering using this module.
This module lets you do some creative things with the JavaScript code in Node.js. There are some things here that are basically a recipe for memory leaks, or at the very least, being broken with each new release of Node, since none of these API surfaces are "technically" "supported" by the team managing the Node.js project.
This module does not ship a copy of Node's internals. It does its thing by using the exposed source code that lives in Node.js itself. So, running this on different versions of Node.js will produce different results.
When your program is broken by changes to Node's internals, or when Node changes in such a way that this module becomes fundamentally broken, you will likely get little sympathy. Many people in the Node community consider this sort of behavior to be unwise and unseemly, if not outright hostile and morally wrong.
At the very least, you probably just want to run Node with the
(undocumented!) --expose-internals
flag, rather than go to such
lengths.
Don't use unless you know what you're doing, or at least, are ok with the risks. Don't say I didn't warn you.
Eternally Yours in OSS,
Isaac Z. Schlueter
var natives = require('natives')
// get the source code
var fsCode = natives.source('fs')
// get a evaluated copy of the module
var fsCopy = natives.require('fs')
// you can pass in a whitelist to NOT shim certain things
var fsCopyWithNativeStreams = natives.require('fs', ['stream'])
// note that this is not the same as the "real" fs
assert(fsCopy !== require('fs'))
// but it does have all the same entries
fsCopy.readFileSync(__filename, 'utf8') // etc
You can't use this to override require("buffer")
because everything
depends on Buffer.isBuffer
working properly, so it's important for
that one to be given a pass.
