+Node.js: fs-extra
+=================
+
+`fs-extra` adds file system methods that aren't included in the native `fs` module and adds promise support to the `fs` methods. It also uses [`graceful-fs`](https://github.com/isaacs/node-graceful-fs) to prevent `EMFILE` errors. It should be a drop in replacement for `fs`.

+[![License](https://img.shields.io/npm/l/fs-extra.svg)](https://github.com/jprichardson/node-fs-extra/blob/master/LICENSE)
+[![build status](https://img.shields.io/github/workflow/status/jprichardson/node-fs-extra/Node.js%20CI/master)](https://github.com/jprichardson/node-fs-extra/actions/workflows/ci.yml?query=branch%3Amaster)
+[![downloads per month](http://img.shields.io/npm/dm/fs-extra.svg)](https://www.npmjs.org/package/fs-extra)
+[![JavaScript Style Guide](https://img.shields.io/badge/code_style-standard-brightgreen.svg)](https://standardjs.com)
+
+Why?
+----
+
+I got tired of including `mkdirp`, `rimraf`, and `ncp` in most of my projects.
+
+
+
+
+Installation
+------------
+
+    npm install fs-extra
+
+
+
+Usage
+-----
+
+`fs-extra` is a drop in replacement for native `fs`. All methods in `fs` are attached to `fs-extra`. All `fs` methods return promises if the callback isn't passed.
+
+You don't ever need to include the original `fs` module again:
+
+```js
+const fs = require('fs') // this is no longer necessary
+```
+
+you can now do this:
+
+```js
+const fs = require('fs-extra')
+```
+
+or if you prefer to make it clear that you're using `fs-extra` and not `fs`, you may want
+to name your `fs` variable `fse` like so:
+
+```js
+const fse = require('fs-extra')
+```
+
+you can also keep both, but it's redundant:
+
+```js
+const fs = require('fs')
+const fse = require('fs-extra')
+```
+
+Sync vs Async vs Async/Await
+-------------
+Most methods are async by default. All async methods will return a promise if the callback isn't passed.
+
+Sync methods on the other hand will throw if an error occurs.
+
+Also Async/Await will throw an error if one occurs.
+
+Example:
+
+```js
+const fs = require('fs-extra')
+
+// Async with promises:
+fs.copy('/tmp/myfile', '/tmp/mynewfile')
+  .then(() => console.log('success!'))
+  .catch(err => console.error(err))
+
+// Async with callbacks:
+fs.copy('/tmp/myfile', '/tmp/mynewfile', err => {
+  if (err) return console.error(err)
+  console.log('success!')
+})
+
+// Sync:
+try {
+  fs.copySync('/tmp/myfile', '/tmp/mynewfile')
+  console.log('success!')
+} catch (err) {
+  console.error(err)
+}
+
+// Async/Await:
+async function copyFiles () {
+  try {
+    await fs.copy('/tmp/myfile', '/tmp/mynewfile')
+    console.log('success!')
+  } catch (err) {
+    console.error(err)
+  }
+}
+
+copyFiles()
+```
+

+
+
+**NOTE:** You can still use the native Node.js methods. They are promisified and copied over to `fs-extra`. See [notes on `fs.read()`, `fs.write()`, & `fs.writev()`](docs/fs-read-write-writev.md)
+
+### What happened to `walk()` and `walkSync()`?
+
+They were removed from `fs-extra` in v2.0.0. If you need the functionality, `walk` and `walkSync` are available as separate packages, [`klaw`](https://github.com/jprichardson/node-klaw) and [`klaw-sync`](https://github.com/manidlou/node-klaw-sync).
+
+
+Third Party
+-----------
+
+### CLI
+
+[fse-cli](https://www.npmjs.com/package/@atao60/fse-cli) allows you to run `fs-extra` from a console or from [npm](https://www.npmjs.com) scripts.
+
+### TypeScript
+
+If you like TypeScript, you can use `fs-extra` with it: https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/fs-extra
+
+
+### File / Directory Watching
+
+If you want to watch for changes to files or directories, then you should use [chokidar](https://github.com/paulmillr/chokidar).
+
+### Obtain Filesystem (Devices, Partitions) Information
+
+[fs-filesystem](https://github.com/arthurintelligence/node-fs-filesystem) allows you to read the state of the filesystem of the host on which it is run. It returns information about both the devices and the partitions (volumes) of the system.
+
+### Misc.
+
+- [fs-extra-debug](https://github.com/jdxcode/fs-extra-debug) - Send your fs-extra calls to [debug](https://npmjs.org/package/debug).
+- [mfs](https://github.com/cadorn/mfs) - Monitor your fs-extra calls.

+
+Hacking on fs-extra
+-------------------
+
+Wanna hack on `fs-extra`? Great! Your help is needed! [fs-extra is one of the most depended upon Node.js packages](http://nodei.co/npm/fs-extra.png?downloads=true&downloadRank=true&stars=true). This project
+uses [JavaScript Standard Style](https://github.com/feross/standard) - if the name or style choices bother you,
+you're gonna have to get over it :) If `standard` is good enough for `npm`, it's good enough for `fs-extra`.
+
+[![js-standard-style](https://cdn.rawgit.com/feross/standard/master/badge.svg)](https://github.com/feross/standard)
+
+What's needed?
+- First, take a look at existing issues. Those are probably going to be where the priority lies.
+- More tests for edge cases. Specifically on different platforms. There can never be enough tests.
+- Improve test coverage.
+
+Note: If you make any big changes, **you should definitely file an issue for discussion first.**
+
+### Running the Test Suite
+
+fs-extra contains hundreds of tests.
+
+- `npm run lint`: runs the linter ([standard](http://standardjs.com/))
+- `npm run unit`: runs the unit tests
+- `npm test`: runs both the linter and the tests
+
+
+### Windows
+
+If you run the tests on the Windows and receive a lot of symbolic link `EPERM` permission errors, it's
+because on Windows you need elevated privilege to create symbolic links. You can add this to your Windows's
+account by following the instructions here: http://superuser.com/questions/104845/permission-to-make-symbolic-links-in-windows-7
+However, I didn't have much luck doing this.
+
+Since I develop on Mac OS X, I use VMWare Fusion for Windows testing. I create a shared folder that I map to a drive on Windows.
+I open the `Node.js command prompt` and run as `Administrator`. I then map the network drive running the following command:
+
+    net use z: "\\vmware-host\Shared Folders"
+
+I can then navigate to my `fs-extra` directory and run the tests.
+
+
+Naming
+------
+
+I put a lot of thought into the naming of these functions. Inspired by @coolaj86's request. So he deserves much of the credit for raising the issue. See discussion(s) here:
+
+* https://github.com/jprichardson/node-fs-extra/issues/2
+* https://github.com/flatiron/utile/issues/11
+* https://github.com/ryanmcgrath/wrench-js/issues/29
+* https://github.com/substack/node-mkdirp/issues/17
+
+First, I believe that in as many cases as possible, the [Node.js naming schemes](http://nodejs.org/api/fs.html) should be chosen. However, there are problems with the Node.js own naming schemes.
+
+For example, `fs.readFile()` and `fs.readdir()`: the **F** is capitalized in *File* and the **d** is not capitalized in *dir*. Perhaps a bit pedantic, but they should still be consistent. Also, Node.js has chosen a lot of POSIX naming schemes, which I believe is great. See: `fs.mkdir()`, `fs.rmdir()`, `fs.chown()`, etc.
+
+We have a dilemma though. How do you consistently name methods that perform the following POSIX commands: `cp`, `cp -r`, `mkdir -p`, and `rm -rf`?
+
+My perspective: when in doubt, err on the side of simplicity. A directory is just a hierarchical grouping of directories and files. Consider that for a moment. So when you want to copy it or remove it, in most cases you'll want to copy or remove all of its contents. When you want to create a directory, if the directory that it's suppose to be contained in does not exist, then in most cases you'll want to create that too.
+
+So, if you want to remove a file or a directory regardless of whether it has contents, just call `fs.remove(path)`. If you want to copy a file or a directory whether it has contents, just call `fs.copy(source, destination)`. If you want to create a directory regardless of whether its parent directories exist, just call `fs.mkdirs(path)` or `fs.mkdirp(path)`.

+/**
+ * Function that returns two types of paths, one relative to symlink, and one
+ * relative to the current working directory. Checks if path is absolute or
+ * relative. If the path is relative, this function checks if the path is
+ * relative to symlink or relative to current working directory. This is an
+ * initiative to find a smarter `srcpath` to supply when building symlinks.
+ * This allows you to determine which path to use out of one of three possible
+ * types of source paths. The first is an absolute path. This is detected by
+ * `path.isAbsolute()`. When an absolute path is provided, it is checked to
+ * see if it exists. If it does it's used, if not an error is returned
+ * (callback)/ thrown (sync). The other two options for `srcpath` are a
+ * relative url. By default Node's `fs.symlink` works by creating a symlink
+ * using `dstpath` and expects the `srcpath` to be relative to the newly
+ * created symlink. If you provide a `srcpath` that does not exist on the file
+ * system it results in a broken symlink. To minimize this, the function
+ * checks to see if the 'relative to symlink' source file exists, and if it
+ * does it will use it. If it does not, it checks if there's a file that
+ * exists that is relative to the current working directory, if does its used.
+ * This preserves the expectations of the original fs.symlink spec and adds
+ * the ability to pass in `relative to current working direcotry` paths.

+Node.js - jsonfile
+================
+
+Easily read/write JSON files in Node.js. _Note: this module cannot be used in the browser._
+
+[![npm Package](https://img.shields.io/npm/v/jsonfile.svg?style=flat-square)](https://www.npmjs.org/package/jsonfile)
+[![linux build status](https://img.shields.io/github/actions/workflow/status/jprichardson/node-jsonfile/ci.yml?branch=master)](https://github.com/jprichardson/node-jsonfile/actions?query=branch%3Amaster)
+[![windows Build status](https://img.shields.io/appveyor/ci/jprichardson/node-jsonfile/master.svg?label=windows%20build)](https://ci.appveyor.com/project/jprichardson/node-jsonfile/branch/master)
+
+<a href="https://github.com/feross/standard"><img src="https://cdn.rawgit.com/feross/standard/master/sticker.svg" alt="Standard JavaScript" width="100"></a>
+
+Why?
+----
+
+Writing `JSON.stringify()` and then `fs.writeFile()` and `JSON.parse()` with `fs.readFile()` enclosed in `try/catch` blocks became annoying.
+
+
+
+Installation
+------------
+
+    npm install --save jsonfile
+
+
+
+API
+---
+
+* [`readFile(filename, [options], callback)`](#readfilefilename-options-callback)
+* [`readFileSync(filename, [options])`](#readfilesyncfilename-options)
+* [`writeFile(filename, obj, [options], callback)`](#writefilefilename-obj-options-callback)
+* [`writeFileSync(filename, obj, [options])`](#writefilesyncfilename-obj-options)
+
+----
+
+### readFile(filename, [options], callback)
+
+`options` (`object`, default `undefined`): Pass in any [`fs.readFile`](https://nodejs.org/api/fs.html#fs_fs_readfile_path_options_callback) options or set `reviver` for a [JSON reviver](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse).
+  - `throws` (`boolean`, default: `true`). If `JSON.parse` throws an error, pass this error to the callback.
+  If `false`, returns `null` for the object.
+
+
+```js
+const jsonfile = require('jsonfile')
+const file = '/tmp/data.json'
+jsonfile.readFile(file, function (err, obj) {
+  if (err) console.error(err)
+  console.dir(obj)
+})
+```
+
+You can also use this method with promises. The `readFile` method will return a promise if you do not pass a callback function.
+
+```js
+const jsonfile = require('jsonfile')
+const file = '/tmp/data.json'
+jsonfile.readFile(file)
+  .then(obj => console.dir(obj))
+  .catch(error => console.error(error))
+```
+
+----
+
+### readFileSync(filename, [options])
+
+`options` (`object`, default `undefined`): Pass in any [`fs.readFileSync`](https://nodejs.org/api/fs.html#fs_fs_readfilesync_path_options) options or set `reviver` for a [JSON reviver](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse).
+- `throws` (`boolean`, default: `true`). If an error is encountered reading or parsing the file, throw the error. If `false`, returns `null` for the object.
+
+```js
+const jsonfile = require('jsonfile')
+const file = '/tmp/data.json'
+
+console.dir(jsonfile.readFileSync(file))
+```
+
+----
+
+### writeFile(filename, obj, [options], callback)
+
+`options`: Pass in any [`fs.writeFile`](https://nodejs.org/api/fs.html#fs_fs_writefile_file_data_options_callback) options or set `replacer` for a [JSON replacer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify). Can also pass in `spaces`, or override `EOL` string or set `finalEOL` flag as `false` to not save the file with `EOL` at the end.
+
+
+```js
+const jsonfile = require('jsonfile')
+
+const file = '/tmp/data.json'
+const obj = { name: 'JP' }
+
+jsonfile.writeFile(file, obj, function (err) {
+  if (err) console.error(err)
+})
+```
+Or use with promises as follows:
+
+```js
+const jsonfile = require('jsonfile')
+
+const file = '/tmp/data.json'
+const obj = { name: 'JP' }
+
+jsonfile.writeFile(file, obj)
+  .then(res => {
+    console.log('Write complete')
+  })
+  .catch(error => console.error(error))
+```
+
+
+**formatting with spaces:**
+
+```js
+const jsonfile = require('jsonfile')
+
+const file = '/tmp/data.json'
+const obj = { name: 'JP' }
+
+jsonfile.writeFile(file, obj, { spaces: 2 }, function (err) {
+  if (err) console.error(err)
+})
+```
+
+**overriding EOL:**
+
+```js
+const jsonfile = require('jsonfile')
+
+const file = '/tmp/data.json'
+const obj = { name: 'JP' }
+
+jsonfile.writeFile(file, obj, { spaces: 2, EOL: '\r\n' }, function (err) {
+  if (err) console.error(err)
+})
+```
+
+
+**disabling the EOL at the end of file:**
+
+```js
+const jsonfile = require('jsonfile')
+
+const file = '/tmp/data.json'
+const obj = { name: 'JP' }
+
+jsonfile.writeFile(file, obj, { spaces: 2, finalEOL: false }, function (err) {
+  if (err) console.log(err)
+})
+```
+
+**appending to an existing JSON file:**
+
+You can use `fs.writeFile` option `{ flag: 'a' }` to achieve this.
+
+```js
+const jsonfile = require('jsonfile')
+
+const file = '/tmp/mayAlreadyExistedData.json'
+const obj = { name: 'JP' }
+
+jsonfile.writeFile(file, obj, { flag: 'a' }, function (err) {
+  if (err) console.error(err)
+})
+```
+
+----
+
+### writeFileSync(filename, obj, [options])
+
+`options`: Pass in any [`fs.writeFileSync`](https://nodejs.org/api/fs.html#fs_fs_writefilesync_file_data_options) options or set `replacer` for a [JSON replacer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify).
