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

-

I am reading / typing a few txt / json files in Node.js which is 25 MB in file size . If a process file in the process is interrupted halfway through the file then I get an empty file. So basically, I'm thinking that anybody knows in an accelerated way to stop the file that after writing the process ends up being corrupted. There is a way to wait until the exit is captured and called fs.writeFile callback?

A common approach is to write a different file first (for example, permanent-file Instead of overwriting .txt , type temporary-file.txt ), and then from the fs.writeFile in the callback, to replace the permanent code Use fs.rename (e.g., fs.rename ('temporary-file.txt', 'permanent-file.txt'); ).

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
