Function truncate

  • Truncates the file. No arguments other than a possible exception are given to the completion callback. A file descriptor can also be passed as the first argument. In this case, fs.ftruncate() is called.

    import { truncate } from 'fs';
    // Assuming that 'path/file.txt' is a regular file.
    truncate('path/file.txt', (err) => {
    if (err) throw err;
    console.log('path/file.txt was truncated');
    });

    Passing a file descriptor is deprecated and may result in an error being thrown in the future.

    See the POSIX truncate(2) documentation for more details.
