Determine whether the file exists Fs. exists (path, function (exists ){}); The above interface is asynchronous, so there is a callback function that can process our various operations in the callback. If you need synchronous operations, you can use the following method: Fs. existsSync (path ); 2. Read File status information fs.stat(path, function(err,
