# mkdirp

Like `mkdir -p`, but in Node.js!

Now with a modern API and no\* bugs!

<small>\* may contain some bugs</small>

# example

## pow.js

```js
// hybrid module, import or require() both work
import { mkdirp } from 'mkdirp'
// or:
const { mkdirp } = require('mkdirp')

// return value is a Promise resolving to the first directory created
mkdirp('/tmp/foo/bar/baz').then(made =>
  console.log(`made directories, starting with ${made}`)
)
```

Output (where `/tmp/foo` already exists)

```
made directories, starting with /tmp/foo/bar
```

Or, if you don't have time to wait around for promises:

```js
import { mkdirp } from 'mkdirp'

// return value is the first directory created
const made = mkdirp.sync('/tmp/foo/bar/baz')
console.log(`made directories, starting with ${made}`)
```

And now /tmp/foo/bar/baz exists, huzzah!

# methods

```js
import { mkdirp } from 'mkdirp'
```

## `mkdirp(dir: string, opts?: MkdirpOptions) => Promise<string | undefined>`

Create a new directory and any necessary subdirectories at `dir`
with octal permission string `opts.mode`. If `opts` is a string
or number, it will be treated as the `opts.mode`.

If `opts.mode` isn't specified, it defaults to `0o777`.

Promise resolves to first directory `made` that had to be
created, or `undefined` if everything already exists. Promise
rejects if any errors are encountered. Note that, in the case of
promise rejection, some directories _may_ have been created, as
recursive directory creation is not an atomic operation.

You can optionally pass in an alternate `fs` implementation by
passing in `opts.fs`. Your implementation should have
`opts.fs.mkdir(path, opts, cb)` and `opts.fs.stat(path, cb)`.

You can also override just one or the other of `mkdir` and `stat`
by passing in `opts.stat` or `opts.mkdir`, or providing an `fs`
option that only overrides one of these.

## `mkdirp.sync(dir: string, opts: MkdirpOptions) => string|undefined`

Synchronously create a new directory and any necessary
subdirectories at `dir` with octal permission string `opts.mode`.
If `opts` is a string or number, it will be treated as the
`opts.mode`.

If `opts.mode` isn't specified, it defaults to `0o777`.

Returns the first directory that had to be created, or undefined
if everything already exists.

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)`.

You can also override just one or the other of `mkdirSync` and
`statSync` by passing in `opts.statSync` or `opts.mkdirSync`, or
providing an `fs` option that only overrides one of these.

## `mkdirp.manual`, `mkdirp.manualSync`

Use the manual implementation (not the native one). This is the
default when the native implementation is not available or the
stat/mkdir implementation is overridden.

## `mkdirp.native`, `mkdirp.nativeSync`

Use the native implementation (not the manual one). This is the
default when the native implementation is available and
stat/mkdir are not overridden.

# implementation

On Node.js v10.12.0 and above, use the native `fs.mkdir(p,
{recursive:true})` option, unless `fs.mkdir`/`fs.mkdirSync` has
been overridden by an option.

## native implementation

- If the path is a root directory, then pass it to the underlying
  implementation and return the result/error. (In this case,
  it'll either succeed or fail, but we aren't actually creating
  any dirs.)
- Walk up the path statting each directory, to find the first
  path that will be created, `made`.
- Call `fs.mkdir(path, { recursive: true })` (or `fs.mkdirSync`)
- If error, raise it to the caller.
- Return `made`.

## manual implementation

- Call underlying `fs.mkdir` implementation, with `recursive:
false`
- If error:
  - If path is a root directory, raise to the caller and do not
    handle it
  - If ENOENT, mkdirp parent dir, store result as `made`
  - stat(path)
    - If error, raise original `mkdir` error
    - If directory, return `made`
    - Else, raise original `mkdir` error
- else
  - return `undefined` if a root dir, or `made` if set, or `path`

## windows vs unix caveat

On Windows file systems, attempts to create a root directory (ie,
a drive letter or root UNC path) will fail. If the root
directory exists, then it will fail with `EPERM`. If the root
directory does not exist, then it will fail with `ENOENT`.

On posix file systems, attempts to create a root directory (in
recursive mode) will succeed silently, as it is treated like just
another directory that already exists. (In non-recursive mode,
of course, it fails with `EEXIST`.)

In order to preserve this system-specific behavior (and because
it's not as if we can create the parent of a root directory
anyway), attempts to create a root directory are passed directly
to the `fs` implementation, and any errors encountered are not
handled.

## native error caveat

The native implementation (as of at least Node.js v13.4.0) does
not provide appropriate errors in some cases (see
[nodejs/node#31481](https://github.com/nodejs/node/issues/31481)
and
[nodejs/node#28015](https://github.com/nodejs/node/issues/28015)).

In order to work around this issue, the native implementation
will fall back to the manual implementation if an `ENOENT` error
is encountered.

# choosing a recursive mkdir implementation

There are a few to choose from! Use the one that suits your
needs best :D

## use `fs.mkdir(path, {recursive: true}, cb)` if:

- You wish to optimize performance even at the expense of other
  factors.
- You don't need to know the first dir created.
- You are ok with getting `ENOENT` as the error when some other
  problem is the actual cause.
- You can limit your platforms to Node.js v10.12 and above.
- You're ok with using callbacks instead of promises.
- You don't need/want a CLI.
- You don't need to override the `fs` methods in use.

## use this module (mkdirp 1.x or 2.x) if:

- You need to know the first directory that was created.
- You wish to use the native implementation if available, but
  fall back when it's not.
- You prefer promise-returning APIs to callback-taking APIs.
- You want more useful error messages than the native recursive
  mkdir provides (at least as of Node.js v13.4), and are ok with
  re-trying on `ENOENT` to achieve this.
- You need (or at least, are ok with) a CLI.
- You need to override the `fs` methods in use.

## use [`make-dir`](http://npm.im/make-dir) if:

- You do not need to know the first dir created (and wish to save
  a few `stat` calls when using the native implementation for
  this reason).
- You wish to use the native implementation if available, but
  fall back when it's not.
- You prefer promise-returning APIs to callback-taking APIs.
- You are ok with occasionally getting `ENOENT` errors for
  failures that are actually related to something other than a
  missing file system entry.
- You don't need/want a CLI.
- You need to override the `fs` methods in use.

## use mkdirp 0.x if:

- You need to know the first directory that was created.
- You need (or at least, are ok with) a CLI.
- You need to override the `fs` methods in use.
- You're ok with using callbacks instead of promises.
- You are not running on Windows, where the root-level ENOENT
  errors can lead to infinite regress.
- You think vinyl just sounds warmer and richer for some weird
  reason.
- You are supporting truly ancient Node.js versions, before even
  the advent of a `Promise` language primitive. (Please don't.
  You deserve better.)

# cli

This package also ships with a `mkdirp` command.

```
$ mkdirp -h

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
  --mode=<mode>  permission string.

  -v --version   Print the mkdirp version number

  -h --help      Print this helpful banner

  -p --print     Print the first directories created for each path provided

  --manual       Use manual implementation, even if native is available
```

# install

With [npm](http://npmjs.org) do:

```
npm install mkdirp
```

to get the library locally, or

```
npm install -g mkdirp
```

to get the command everywhere, or

```
npx mkdirp ...
```

to run the command without installing it globally.

# platform support

This module works on node v8, but only v10 and above are officially
supported, as Node v8 reached its LTS end of life 2020-01-01, which is in
the past, as of this writing.
