Move files and directories.

const move = require('move-concurrently')
|
|

|
move('/path/to/thing', '/new/path/thing').then(() => {
|
|
8
|
// thing is now moved!
|
|

|
}).catch(err => {
|
|
10
|
// oh no!
|

})

|
Uses `rename` to move things as fast as possible.
|
|
15
|
|
|
16
|
If you `move` across devices or on filesystems that don't support renaming
|
|
17
|
large directories. That is, situations that result in `rename` returning
|
|
18
|
the `EXDEV` error, then `move` will fallback to copy + delete.
|
|
19
|
|
|
20
|
When recursively copying directories it will first try to rename the
|
|
21
|
contents before falling back to copying. While this will be slightly slower
|
|
22
|
in true cross-device scenarios, it is MUCH faster in cases where the
|
|
23
|
filesystem can't handle directory renames.
|
|
24
|
|
|
25
|
When copying ownership is maintained when running as root. Permissions are
|
|
26
|
always maintained. On Windows, if symlinks are unavailable then junctions
|
|
27
|
will be used.

### move(from, to, options) → Promise
|
|
32
|
|
|
33
|
Recursively moves `from` to `to` and resolves its promise when finished.
|
|
34
|
If `to` already exists then the promise will be rejected with an `EEXIST`
|
|
35
|
error.
|
|
36
|
|
|
37
|
Starts by trying to rename `from` to `to`.
|
|

|
Options are:
|
|
40
|
|
|
41
|
* maxConcurrency – (Default: `1`) The maximum number of concurrent copies to do at once.
|
|
42
|
* isWindows - (Default: `process.platform === 'win32'`) If true enables Windows symlink semantics. This requires
|
|
43
|
an extra `stat` to determine if the destination of a symlink is a file or directory. If symlinking a directory
|
|
44
|
fails then we'll try making a junction instead.
|
|
45
|
|
|
46
|
Options can also include dependency injection:
|
|
47
|
|
|
48
|
* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
|
|
49
|
* fs - (Default: `require('fs')`) The filesystem module to use. Can be used
|
|
50
|
to use `graceful-fs` or to inject a mock.
|
|
51
|
* writeStreamAtomic - (Default: `require('fs-write-stream-atomic')`) The
|
|
52
|
implementation of `writeStreamAtomic` to use. Used to inject a mock.
|
|
53
|
* getuid - (Default: `process.getuid`) A function that returns the current UID. Used to inject a mock.
