copy(src, dest, [options], [callback])
Recursively copy files and folders from src
to dest
Name | Type | Required | Default | Description |
---|---|---|---|---|
src | string | Yes | N/A | Source file/folder path |
dest | string | Yes | N/A | Destination file/folder path |
options.overwrite | boolean | No | false | Whether to overwrite destination files |
options.expand | boolean | No | false | Whether to expand symbolic links |
options.dot | boolean | No | false | Whether to copy files beginning with a . |
options.junk | boolean | No | false | Whether to copy OS junk files (e.g. .DS_Store , Thumbs.db ) |
options.filter | function , RegExp , string , array | No | null | Filter function / regular expression / glob that determines which files to copy (uses maximatch) |
options.rename | function | No | null | Function that maps source paths to destination paths |
options.transform | function | No | null | Function that returns a transform stream used to modify file contents |
options.results | boolean | No | true | Whether to return an array of copy results |
options.concurrency | number | No | 255 | Maximum number of simultaneous copy operations |

Promise<Array>
Promise, fulfilled with array of copy results:
[
{
"src": "/path/to/src",
"dest": "/path/to/dest",
"stats": <Stats>
},
{
"src": "/path/to/src/file.txt",
"dest": "/path/to/dest/file.txt",
"stats": <Stats>
},
{
"src": "/path/to/src/subfolder",
"dest": "/path/to/dest/subfolder",
"stats": <Stats>
},
{
"src": "/path/to/src/subfolder/nested.txt",
"dest": "/path/to/dest/subfolder/nested.txt",
"stats": <Stats>
}
]
The value returned by the copy
function implements the EventEmitter
interface, and emits the following events:
Event | Handler signature |
---|---|
copy.events.ERROR | function(error, ErrorInfo) |
copy.events.COMPLETE | function(Array<CopyOperation>) |
copy.events.CREATE_DIRECTORY_START | function(CopyOperation) |
copy.events.CREATE_DIRECTORY_ERROR | function(error, CopyOperation) |
copy.events.CREATE_DIRECTORY_COMPLETE | function(CopyOperation) |
copy.events.CREATE_SYMLINK_START | function(CopyOperation) |
copy.events.CREATE_SYMLINK_ERROR | function(error, CopyOperation) |
copy.events.CREATE_SYMLINK_COMPLETE | function(CopyOperation) |
copy.events.COPY_FILE_START | function(CopyOperation) |
copy.events.COPY_FILE_ERROR | function(error, CopyOperation) |
copy.events.COPY_FILE_COMPLETE | function(CopyOperation) |
...where the types referred to in the handler signature are as follows:
ErrorInfo
Property | Type | Description |
---|---|---|
src | string | Source path of the file/folder/symlink that failed to copy |
dest | string | Destination path of the file/folder/symlink that failed to copy |
CopyOperation
Property | Type | Description |
---|---|---|
src | string | Source path of the relevant file/folder/symlink |
dest | string | Destination path of the relevant file/folder/symlink |
stats | fs.Stats | Stats for the relevant file/folder/symlink |
