nodejs get file name from absolute path?

Question

How can I get the file name from an absolute path in Nodejs?

e.g. "foo.txt" from "/var/www/foo.txt"

I know it works with a string operation, like fullpath.replace(/.+\//, ''), but I want to know is there an explicit way, like file.getName() in Java?

Answer 1

Use the basename method of the path module:

path.basename('/foo/bar/baz/asdf/quux.html')
// returns
'quux.html'

Here is the documentation the above example is taken from.

Answer 2

To get the file name portion of the file name, the basename method is used:

var path = require("path");
var fileName = "C:\\Python27\\ArcGIS10.2\\python.exe";
var file = path.basename(fileName);

console.log(file); // 'python.exe'

If you want the file name without the extension, you can pass the extension variable (containing the extension name) to the basename method telling Node to return only the name without the extension:

var path = require("path");
var fileName = "C:\\Python27\\ArcGIS10.2\\python.exe";
var extension = path.extname(fileName);
var file = path.basename(fileName,extension);

console.log(file); // 'python'
