fs.writeFile(file, data[, options], callback)#
History:

• file <string> | <Buffer> | <URL> | <integer> filename or file descriptor
  
• data

  <string> | <Buffer> | <TypedArray> | <DataView> | <Object>

  
  
• options <Object> | <string>
  • encoding <string> | <null> Default: 'utf8'
    
  • mode <integer> Default: 0o666
    
  • flag <string> See support of file system flags. Default: 'w'.
    
  • signal <AbortSignal> allows aborting an in-progress writeFile
    
  
  
• callback <Function>
  • err <Error> | <AggregateError>
    
  
  
  

When file is a filename, asynchronously writes data to the file, replacing the file if it already exists. data can be a string or a buffer.

When file is a file descriptor, the behavior is similar to calling fs.write() directly (which is recommended). See the notes below on using a file descriptor.

The encoding option is ignored if data is a buffer.

If data is a plain object, it must have an own (not inherited) toString function property.
