Like FS streams, but with stat on them, and supporting directories and
symbolic links, as well as normal files. Also, you can use this to set
the stats on a file, even if you don't change its contents, or to create
a symlink, etc.
So, for example, you can "write" a directory, and it'll call `mkdir`. You
can specify a uid and gid, and it'll call `chown`. You can specify a
`mtime` and `atime`, and it'll call `utimes`. You can call it a symlink
and provide a `linkpath` and it'll call `symlink`.
Note that it won't automatically resolve symbolic links. So, if you
call `fstream.Reader('/some/symlink')` then you'll get an object
that stats and then ends immediately (since it has no data). To follow
symbolic links, do this: `fstream.Reader({path:'/some/symlink', follow:
true })`.
There are various checks to make sure that the bytes emitted are the
same as the intended size, if the size is set.
## Examples
```javascript
fstream
.Writer({ path: "path/to/file"
, mode: 0755
, size: 6
})
.write("hello\n")
.end()
```
This will create the directories if they're missing, and then write
`hello\n` into the file, chmod it to 0755, and assert that 6 bytes have
been written when it's done.
```javascript
fstream
.Writer({ path: "path/to/file"
, mode: 0755
, size: 6
, flags: "a"
})
.write("hello\n")
.end()
```
You can pass flags in, if you want to append to a file.
```javascript
fstream
.Writer({ path: "path/to/symlink"
, linkpath: "./file"
, SymbolicLink: true
, mode: "0755" // octal strings supported
})
.end()
```
If isSymbolicLink is a function, it'll be called, and if it returns
true, then it'll treat it as a symlink. If it's not a function, then
any truish value will make a symlink, or you can set `type:
'SymbolicLink'`, which does the same thing.
Note that the linkpath is relative to the symbolic link location, not
the parent dir or cwd.
```javascript
fstream
.Reader("path/to/dir")
.pipe(fstream.Writer("path/to/other/dir"))
```
This will do like `cp -Rp path/to/dir path/to/other/dir`. If the other
dir exists and isn't a directory, then it'll emit an error. It'll also
set the uid, gid, mode, etc. to be identical. In this way, it's more
like `rsync -a` than simply a copy.

# graceful-fs
graceful-fs functions as a drop-in replacement for the fs module,
making various improvements.
The improvements are meant to normalize behavior across different
platforms and environments, and to make filesystem access more
resilient to errors.
## Improvements over [fs module](https://nodejs.org/api/fs.html)
* Queues up `open` and `readdir` calls, and retries them once
something closes if there is an EMFILE error from too many file
descriptors.
* fixes `lchmod` for Node versions prior to 0.6.2.
* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
`lchown` if the user isn't root.
* makes `lchmod` and `lchown` become noops, if not available.
* retries reading a file if `read` results in EAGAIN error.
On Windows, it retries renaming a file for up to one second if `EACCESS`
or `EPERM` error occurs, likely because antivirus software has locked
the directory.
## USAGE
```javascript
// use just like fs
var fs = require('graceful-fs')
// now go and do stuff with it...
fs.readFile('some-file-or-whatever', (err, data) => {
// Do stuff here.
})
```
## Sync methods
This module cannot intercept or handle `EMFILE` or `ENFILE` errors from sync
methods. If you use sync methods which open file descriptors then you are
responsible for dealing with any errors.
This is a known limitation, not a bug.
## Global Patching
If you want to patch the global fs module (or any other fs-like
module) you can do this:
```javascript
// Make sure to read the caveat below.
var realFs = require('fs')
var gracefulFs = require('graceful-fs')
gracefulFs.gracefulify(realFs)
```
This should only ever be done at the top-level application layer, in
order to delay on EMFILE errors from any fs-using dependencies. You
should **not** do this in a library, because it can cause unexpected
delays in other parts of the program.
## Changes
This module is fairly stable at this point, and used by a lot of
things. That being said, because it implements a subtle behavior
change in a core part of the node API, even modest changes can be
extremely breaking, and the versioning is thus biased towards
bumping the major when in doubt.
The main change between major versions has been switching between
providing a fully-patched `fs` module vs monkey-patching the node core
builtin, and the approach by which a non-monkey-patched `fs` was
created.
The goal is to trade `EMFILE` errors for slower fs operations. So, if
you try to open a zillion files, rather than crashing, `open`
operations will be queued up and wait for something else to `close`.
There are advantages to each approach. Monkey-patching the fs means
that no `EMFILE` errors can possibly occur anywhere in your
application, because everything is using the same core `fs` module,
which is patched. However, it can also obviously cause undesirable
side-effects, especially if the module is loaded multiple times.
Implementing a separate-but-identical patched `fs` module is more
surgical (and doesn't run the risk of patching multiple times), but
also imposes the challenge of keeping in sync with the core module.
The current approach loads the `fs` module, and then creates a
lookalike object that has all the same methods, except a few that are
patched. It is safe to use in all versions of Node from 0.8 through
7.0.
### v4
* Do not monkey-patch the fs module. This module may now be used as a
drop-in dep, and users can opt into monkey-patching the fs builtin
if their app requires it.
### v3
* Monkey-patch fs, because the eval approach no longer works on recent
node.
* fixed possible type-error throw if rename fails on windows
* verify that we *never* get EMFILE errors
* Ignore ENOSYS from chmod/chown
* clarify that graceful-fs must be used as a drop-in
### v2.1.0
* Use eval rather than monkey-patching fs.
* readdir: Always sort the results
* win32: requeue a file if error has an OK status
### v2.0
* A return to monkey patching
* wrap process.cwd
### v1.1
* wrap readFile
* Wrap fs.writeFile.
* readdir protection
* Don't clobber the fs builtin
* Handle fs.read EAGAIN errors by trying again
* Expose the curOpen counter
* No-op lchown/lchmod if not implemented
* fs.rename patch only for win32
* Patch fs.rename to handle AV software on Windows
* Close #4 Chown should not fail on einval or eperm if non-root
* Fix isaacs/fstream#1 Only wrap fs one time
* Fix #3 Start at 1024 max files, then back off on EMFILE
* lutimes that doens't blow up on Linux
* A full on-rewrite using a queue instead of just swallowing the EMFILE error
* Wrap Read/Write streams as well
### 1.0
* Update engines for node 0.6
* Be lstat-graceful on Windows
* first

Browser-friendly inheritance fully compatible with standard node.js
[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
This package exports standard `inherits` from node.js `util` module in
node environment, but also provides alternative browser-friendly
implementation through [browser
field](https://gist.github.com/shtylman/4339901). Alternative
implementation is a literal copy of standard one located in standalone
module to avoid requiring of `util`. It also has a shim for old
browsers with no `Object.create` support.
While keeping you sure you are using standard `inherits`
implementation in node.js environment, it allows bundlers such as
[browserify](https://github.com/substack/node-browserify) to not
include full `util` package to your client code if all you need is
just `inherits` function. It worth, because browser shim for `util`
package is large and `inherits` is often the single function you need
from it.
It's recommended to use this package instead of
`require('util').inherits` for any code that has chances to be used
not only in node.js but in browser too.
## usage
```js
var inherits = require('inherits');
// then use exactly as the standard one
```
## note on version ~1.0
Version ~1.0 had completely different motivation and is not compatible
neither with 2.0 nor with standard node.js `inherits`.
If you are using version ~1.0 and planning to switch to ~2.0, be
careful:
* new version uses `super_` instead of `super` for referencing
superclass
* new version overwrites current prototype while old one preserves any
existing fields on it

# mkdirp
Like `mkdir -p`, but in node.js!
[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
# example
## pow.js
```js
var mkdirp = require('mkdirp');
mkdirp('/tmp/foo/bar/baz', function (err) {
if (err) console.error(err)
else console.log('pow!')
});
```
Output
```
pow!
```
And now /tmp/foo/bar/baz exists, huzzah!
# methods
```js
var mkdirp = require('mkdirp');
```
## mkdirp(dir, opts, cb)
Create a new directory and any necessary subdirectories at `dir` with octal
permission string `opts.mode`. If `opts` is a non-object, it will be treated as
the `opts.mode`.
If `opts.mode` isn't specified, it defaults to `0777`.
`cb(err, made)` fires with the error or the first directory `made`
that had to be created, if any.
You can optionally pass in an alternate `fs` implementation by passing in
`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
`opts.fs.stat(path, cb)`.
## mkdirp.sync(dir, opts)
Synchronously create a new directory and any necessary subdirectories at `dir`
with octal permission string `opts.mode`. If `opts` is a non-object, it will be
treated as the `opts.mode`.
If `opts.mode` isn't specified, it defaults to `0777`.
Returns the first directory that had to be created, if any.
You can optionally pass in an alternate `fs` implementation by passing in
`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
`opts.fs.statSync(path)`.
# usage
This package also ships with a `mkdirp` command.
```
usage: mkdirp [DIR1,DIR2..] {OPTIONS}
Create each supplied directory including any necessary parent directories that
don't yet exist.
If the directory already exists, do nothing.
OPTIONS are:
-m, --mode If a directory needs to be created, set the mode as an octal
permission string.
```
# install
With [npm](http://npmjs.org) do:
```
npm install mkdirp
```
to get the library, or
```
npm install -g mkdirp
```
to get the command.

[![Build Status](https://travis-ci.org/isaacs/rimraf.svg?branch=master)](https://travis-ci.org/isaacs/rimraf) [![Dependency Status](https://david-dm.org/isaacs/rimraf.svg)](https://david-dm.org/isaacs/rimraf) [![devDependency Status](https://david-dm.org/isaacs/rimraf/dev-status.svg)](https://david-dm.org/isaacs/rimraf#info=devDependencies)
The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
Install with `npm install rimraf`, or just drop rimraf.js somewhere.
## API
`rimraf(f, [opts], callback)`
The first parameter will be interpreted as a globbing pattern for files. If you
want to disable globbing you can do so with `opts.disableGlob` (defaults to
`false`). This might be handy, for instance, if you have filenames that contain
globbing wildcard characters.
The callback will be called with an error if there is one. Certain
errors are handled for you:
* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
`opts.maxBusyTries` times before giving up, adding 100ms of wait
between each attempt. The default `maxBusyTries` is 3.
* `ENOENT` - If the file doesn't exist, rimraf will return
successfully, since your desired outcome is already the case.
* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
possible to hit `EMFILE` if too many file descriptors are in use.
In the sync case, there's nothing to be done for this. But in the
async case, rimraf will gradually back off with timeouts up to
`opts.emfileWait` ms, which defaults to 1000.
## options
* unlink, chmod, stat, lstat, rmdir, readdir,
unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
In order to use a custom file system library, you can override
specific fs functions on the options object.
If any of these functions are present on the options object, then
the supplied function will be used instead of the default fs
method.
Sync methods are only relevant for `rimraf.sync()`, of course.
For example:
```javascript
var myCustomFS = require('some-custom-fs')
rimraf('some-thing', myCustomFS, callback)
```
* maxBusyTries
If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
on Windows systems, then rimraf will retry with a linear backoff
wait of 100ms longer on each try. The default maxBusyTries is 3.
Only relevant for async usage.
* emfileWait
If an `EMFILE` error is encountered, then rimraf will retry
repeatedly with a linear backoff of 1ms longer on each try, until
the timeout counter hits this max. The default limit is 1000.
If you repeatedly encounter `EMFILE` errors, then consider using
[graceful-fs](http://npm.im/graceful-fs) in your program.
Only relevant for async usage.
* glob
Set to `false` to disable [glob](http://npm.im/glob) pattern
matching.
Set to an object to pass options to the glob module. The default
glob options are `{ nosort: true, silent: true }`.
Glob version 6 is used in this module.
Relevant for both sync and async usage.
* disableGlob
Set to any non-falsey value to disable globbing entirely.
(Equivalent to setting `glob: false`.)
## rimraf.sync
It can remove stuff synchronously, too. But that's not so good. Use
the async API. It's better.
## CLI
If installed with `npm install rimraf -g` it can be used as a global
command `rimraf <path> [<path> ...]` which is useful for cross platform support.
## mkdirp
If you need to create a directory recursively, check out
[mkdirp](https://github.com/substack/node-mkdirp).
