To get the file name or the last portion from a path, you can use the basename() method from the path module in Node.js.
Let's say we have a pathname called /app/controllers/index.js like this,
// pathname
const pathname = "/app/controllers/index.js";
We can get the filename from the above path by passing the pathname as an argument to the path.basename() method like this,
// require path module
const path = require("path");
// path name
const pathname = "/app/controllers/index.js";
// pass the pathname as an argument
// to path.basename() method
// to get the filename or last portion from the path
const filename = path.basename(pathname);
console.log(filename); // index.js
- The
path.basename()method returns the file name.
See this example live in repl.it.
