# 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

# pify [](https://travis-ci.org/sindresorhus/pify)
|
||||
|
||||
> Promisify a callback-style function
|
||||
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
$ npm install --save pify
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
const fs = require('fs');
|
||||
const pify = require('pify');
|
||||
|
||||
// promisify a single function
|
||||
|
||||
pify(fs.readFile)('package.json', 'utf8').then(data => {
|
||||
console.log(JSON.parse(data).name);
|
||||
//=> 'pify'
|
||||
});
|
||||
|
||||
// or promisify all methods in a module
|
||||
|
||||
pify(fs).readFile('package.json', 'utf8').then(data => {
|
||||
console.log(JSON.parse(data).name);
|
||||
//=> 'pify'
|
||||
});
|
||||
```
|
||||
|
||||
|
||||
## API
|
||||
|
||||
### pify(input, [promiseModule], [options])
|
||||
|
||||
Returns a promise wrapped version of the supplied function or module.
|
||||
|
||||
#### input
|
||||
|
||||
Type: `function`, `object`
|
||||
|
||||
Callback-style function or module whose methods you want to promisify.
|
||||
|
||||
#### promiseModule
|
||||
|
||||
Type: `function`
|
||||
|
||||
Custom promise module to use instead of the native one.
|
||||
|
||||
Check out [`pinkie-promise`](https://github.com/floatdrop/pinkie-promise) if you need a tiny promise polyfill.
|
||||
|
||||
#### options
|
||||
|
||||
##### multiArgs
|
||||
|
||||
Type: `boolean`
|
||||
Default: `false`
|
||||
|
||||
By default, the promisified function will only return the second argument from the callback, which works fine for most APIs. This option can be useful for modules like `request` that return multiple arguments. Turning this on will make it return an array of all arguments from the callback, excluding the error argument, instead of just the second argument.
|
||||
|
||||
```js
|
||||
const request = require('request');
|
||||
const pify = require('pify');
|
||||
|
||||
pify(request, {multiArgs: true})('https://sindresorhus.com').then(result => {
|
||||
const [httpResponse, body] = result;
|
||||
});
|
||||
```
|
||||
|
||||
##### include
|
||||
|
||||
Type: `array` of (`string`|`regex`)
|
||||
|
||||
Methods in a module to promisify. Remaining methods will be left untouched.
|
||||
|
||||
##### exclude
|
||||
|
||||
Type: `array` of (`string`|`regex`)
|
||||
Default: `[/.+Sync$/]`
|
||||
|
||||
Methods in a module **not** to promisify. Methods with names ending with `'Sync'` are excluded by default.
|
||||
|
||||
##### excludeMain
|
||||
|
||||
Type: `boolean`
|
||||
Default: `false`
|
||||
|
||||
By default, if given module is a function itself, this function will be promisified. Turn this option on if you want to promisify only methods of the module.
|
||||
|
||||
```js
|
||||
const pify = require('pify');
|
||||
|
||||
function fn() {
|
||||
return true;
|
||||
}
|
||||
|
||||
fn.method = (data, callback) => {
|
||||
setImmediate(() => {
|
||||
callback(data, null);
|
||||
});
|
||||
};
|
||||
|
||||
// promisify methods but not fn()
|
||||
const promiseFn = pify(fn, {excludeMain: true});
|
||||
|
||||
if (promiseFn()) {
|
||||
promiseFn.method('hi').then(data => {
|
||||
console.log(data);
|
||||
});
|
||||
}
|
||||
