Copy files, directories and symlinks
t copy = require('copy-concurrently')
('/path/to/thing', '/new/path/thing').then(() => {
this is now copied
atch(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.
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:
1) The maximum number of concurrent copies to do at once.copy.item) The function to call on each file after recursing into a directory.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:
global.Promise) The promise implementation to use, defaults to Node's.require('fs')) The filesystem module to use. Can be used
to use graceful-fs or to inject a mock.require('fs-write-stream-atomic')) The
implementation of writeStreamAtomic to use. Used to inject a mock.process.getuid) A function that returns the current UID. Used to inject a mock.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.
Copies an ordinary file from to destination to. Uses
fs-write-stream-atomic to ensure that the file is either entirely copied
or not at all.
Options are:
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.to will have its perms set to mode.require('fs')) The filesystem module to use. Can be used
to use graceful-fs or to inject a mock.global.Promise) The promise implementation to use, defaults to Node's.require('fs-write-stream-atomic')) The
implementation of writeStreamAtomic to use. Used to inject a mock.Copies a symlink from to destination to. If you're using Windows and
symlinking fails and what you're linking is a directory then junctions will
be tried instead.
Options are:
require('fs')) The filesystem module to use. Can be used

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.Reads all of the files in directory from and adds them to the queue
using recurseWith (by default copy.item).
Options are:
run-queue object to add files found inside from to.copy.item) The function to call on each file after recursing into a directory.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.to will have its perms set to mode.require('fs')) The filesystem module to use. Can be used
to use graceful-fs or to inject a mock.process.getuid) A function that returns the current UID. Used to inject a mock.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:
run-queue object to
pass to copy.recurse if from is a directory.copy.item) The function to call on each file after recursing into a directory.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.to will have its perms set to mode.require('fs')) The filesystem module to use. Can be used
