# copySync(src, dest, [options])
|
||
|
|
|
||
|
|
Copy a file or directory. The directory can have contents. Like `cp -r`.
|
||
|
|
|
||
|
|
- `src` `<String>`
|
||
|
|
- `dest` `<String>`
|
||
|
|
- `options` `<Object>`
|
||
|
|
- `overwrite` `<boolean>`: overwrite existing file or directory, default is `true`. _Note that the copy operation will silently fail if you set this to `false` and the destination exists._ Use the `errorOnExist` option to change this behavior.
|
||
|
|
- `errorOnExist` `<boolean>`: when `overwrite` is `false` and the destination exists, throw an error. Default is `false`.
|
||
|
|
- `dereference` `<boolean>`: dereference symlinks, default is `false`.
|
||
|
|
- `preserveTimestamps` `<boolean>`: will set last modification and access times to the ones of the original source files, default is `false`.
|
||
|
|
- `filter` `<Function>`: Function to filter copied files. Return `true` to include, `false` to exclude. This can also be a RegExp, however this is deprecated (See [issue #239](https://github.com/jprichardson/node-fs-extra/issues/239) for background).
|
||
|
|
|
||
|
|
## Example:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const fs = require('fs-extra')
|
||
|
|
|
||
|
|
// copy file
|
||
|
|
fs.copySync('/tmp/myfile', '/tmp/mynewfile')
|
||
|
|
|
||
|
|
// copy directory, even if it has subdirectories or files
|
||
|
|
fs.copySync('/tmp/mydir', '/tmp/mynewdir')
|
||
|
|
```
|
||
|
|
|
||
|
|
**Using filter function**
|
||
|
|
|
||
|
|
```js
|
||
|
|
const fs = require('fs-extra')
|
||
|
|
|
||
|
|
const filterFunc = (src, dest) => {
|
||
|
|
// your logic here
|
||
|
|
// it will be copied if return true
|
||
|
|
}
|
||
|
|
|
||
|
|
fs.copySync('/tmp/mydir', '/tmp/mynewdir', { filter: filterFunc })
|
||
|
|
```
