How to use the Dir Function in JavaScript's Async Module

dir is a function in JavaScript's Async Module. The dir function is used to search for a file. The first parameter is the path to the file. The second parameter is the options. The third parameter is the callback.

The path parameter is the path to the file. The options parameter is an object that contains the following properties:

  • The callback parameter is the function that is called when the search is complete.

The following code samples show how to use the dir function.

The first code sample shows how to search for a file in the current directory.

var path = "./file.txt";

var options = {
    dir: path,
    recursive: true,
    callback: function(err, files) {
    console.log(files);
    }
};

async.dir(path, options, function(err, files) {
	console.log(files);
});

The second code sample shows how to search for a file in a specific directory.

var path = "../file.txt";

var options = {
    dir: path,
    recursive: true,
    callback: function(err, files) {
    console.log(files);
	}
};

async.dir(path, options, function(err, files) {
	console.log(files);
});
