# copy-concurrently
Copy files, directories and symlinks
```
const copy = require('copy-concurrently')
copy('/path/to/thing', '/new/path/thing').then(() => {
// this is now copied
}).catch(err => {
// oh noooo
})
```
Copies files, directories and symlinks. Ownership is maintained when
running as root, permissions are always maintained. On Windows, if symlinks
are unavailable then junctions will be used.
## PUBLIC INTERFACE
### copy(from, to, [options]) → Promise
Recursively copies `from` to `to` and resolves its promise when finished.
If `to` already exists then the promise will be rejected with an `EEXIST`
error.
Options are:
* maxConcurrency (Default: `1`) The maximum number of concurrent copies to do at once.
* recurseWith - (Default: `copy.item`) The function to call on each file after recursing into a directory.
* isWindows - (Default: `process.platform === 'win32'`) If true enables Windows symlink semantics. This requires
an extra `stat` to determine if the destination of a symlink is a file or directory. If symlinking a directory
fails then we'll try making a junction instead.
Options can also include dependency injection:
* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
* fs - (Default: `require('fs')`) The filesystem module to use. Can be used
to use `graceful-fs` or to inject a mock.
* writeStreamAtomic - (Default: `require('fs-write-stream-atomic')`) The
implementation of `writeStreamAtomic` to use. Used to inject a mock.
* getuid - (Default: `process.getuid`) A function that returns the current UID. Used to inject a mock.
## EXTENSION INTERFACE
Ordinarily you'd only call `copy` above. But it's possible to use it's
component functions directly. This is useful if, say, you're writing
[move-concurently](https://npmjs.com/package/move-concurrently).
### copy.file(from, to, options) → Promise
Copies a ordinary file `from` to destination `to`. Uses
`fs-write-stream-atomic` to ensure that the file is entirely copied or not
at all.
Options are:
* uid, gid - (Optional) If `getuid()` is `0` then this and gid will be used to
set the user and group of `to`. If uid is present then gid must be too.
* mode - (Optional) If set then `to` will have its perms set to `mode`.
* fs - (Default: `require('fs')`) The filesystem module to use. Can be used
to use `graceful-fs` or to inject a mock.
* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
* writeStreamAtomic - (Default `require('fs-write-stream-atomic')`) The
implementation of `writeStreamAtomic` to use. Used to inject a mock.
### copy.symlink(from, to, options) → Promise
Copies a symlink `from` to destination `to`. If on Windows then if
symlinking fails, a junction will be used instead.
Options are:
* top - The top level the copy is being run from. This is used to determine
if the symlink destination is within the set of files we're copying or
outside it.
* fs - (Default: `require('fs')`) The filesystem module to use. Can be used
to use `graceful-fs` or to inject a mock.
* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
* isWindows - (Default: `process.platform === 'win32'`) If true enables Windows symlink semantics. This requires
an extra `stat` to determine if the destination of a symlink is a file or directory. If symlinking a directory
fails then we'll try making a junction instead.
### copy.recurse(from, to, options) → Promise
Reads all of the files in directory `from` and adds them to the `queue`
using `recurseWith` (by default `copy.item`).
Options are:
* queue - A [`run-queue`](https://npmjs.com/package/run-queue) object to add files found inside `from` to.
* recurseWith - (Default: `copy.item`) The function to call on each file after recursing into a directory.
* uid, gid - (Optional) If `getuid()` is `0` then this and gid will be used to
set the user and group of `to`. If uid is present then gid must be too.
* mode - (Optional) If set then `to` will have its perms set to `mode`.
* fs - (Default: `require('fs')`) The filesystem module to use. Can be used
to use `graceful-fs` or to inject a mock.
* getuid - (Default: `process.getuid`) A function that returns the current UID. Used to inject a mock.
### copy.item(from, to, options) → Promise
Copies some kind of `from` to destination `to`. This looks at the filetype
and calls `copy.file`, `copy.symlink` or `copy.recurse` as appropriate.
Symlink copies are queued with a priority such that they happen after all
file and directory copies as you can't create a junction on windows to a
file that doesn't exist yet.
Options are:
* top - The top level the copy is being run from. This is used to determine
if the symlink destination is within the set of files we're copying or
outside it.
* queue - The [`run-queue`](https://npmjs.com/package/run-queue) object to
pass to `copy.recurse` if `from` is a directory.
* recurseWith - (Default: `copy.item`) The function to call on each file after recursing into a directory.
* uid, gid - (Optional) If `getuid()` is `0` then this and gid will be used to
set the user and group of `to`. If uid is present then gid must be too.
* mode - (Optional) If set then `to` will have its perms set to `mode`.
* fs - (Default: `require('fs')`) The filesystem module to use. Can be used
to use `graceful-fs` or to inject a mock.
* getuid - (Default: `process.getuid`) A function that returns the current UID. Used to inject a mock.
* isWindows - (Default: `process.platform === 'win32'`) If true enables Windows symlink semantics. This requires
an extra `stat` to determine if the destination of a symlink is a file or directory. If symlinking a directory
fails then we'll try making a junction instead.
* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
* writeStreamAtomic - (Default `require('fs-write-stream-atomic')`) The
implementation of `writeStreamAtomic` to use. Used to inject a mock.
