javascript - Prevent file corruption on exiting node in middle of fs.writeFile -

i'm reading , writing txt/json files in node.js have become >25mb in file size. if process interrupted half way through fs.writefile empty file. basically, i'm wondering if knows of quick way prevent file writes beingness corrupted if process exited. there way grab exit , wait until fs.writefile callback called?

a mutual approach first write different file (e.g., instead of overwriting permanent-file.txt directly, write temporary-file.txt), , in callback fs.writefile, utilize fs.rename replace permanent file temporary 1 (e.g., fs.rename('temporary-file.txt', 'permanent-file.txt');).
