atomic-write: Atomically write to a file

[ library, mit, system ] [ Propose Tags ]

Atomically write to a file on POSIX-compliant systems while preserving permissions.

On most Unix systems, mv is an atomic operation. This makes it simple to write to a file atomically just by using the mv operation. However, this will destroy the permissions on the original file. This library does the following to preserve permissions while atomically writing to a file:

This way, when the file is mv'ed into place, the permissions will be the ones held by the original file.

This library is based on similar implementations found in common libraries in Ruby and Python:

Note that at this time Windows is not supported, however we would appreciate contributions to the github repository.
