node-copy-dereference
Copy a file or directory, dereferencing symlinks in the process, and
preserving last-modified times and file modes.Made for use by Broccoli and Broccoli plugins.
Installation
npm install --save copy-dereference
Example
var copyDereferenceSync = require('copy-dereference').sync;
copyDereferenceSync('src_dir/some_file.txt', 'dest_dir/some_file.txt');
copyDereferenceSync('src_dir/some_dir', 'dest_dir/some_dir');
Description
copyDereferenceSync(srcPath, destPath)
Copy the file or directory at
srcPath
to destPath
.If
srcPath
is a symlink, or if there is a symlink somewhere underneath the
directory at srcPath
, it will be dereferenced, that is, it will be replaced
with the thing it points to.File & directory last-modified times as well as file modes (permissions & executable bit) will be preserved.
We throw an exception if there are any broken symlinks at or beneath
srcPath
, if srcPath
does not exist, of if destPath
's parent directory
does not exist.Furthermore, we throw an exception if
destPath
already exists. Thus in
contrast to Unix cp
, the following will fail:// dest_dir already exists, and we might expect dest_dir/some_dir to be
// created. This does not work; pass 'dest_dir/some_dir' instead.
copyDereferenceSync('src_dir/some_dir', 'dest_dir');
File types other than files, directories and symlinks (such as device files or sockets) are not supported and will cause an exception.
