We need to write a function that takes in a string file path and returns the filename. Filename usually lives right at the very end of any path, although we can solve this problem using regex but there exists a simpler one-line solution to it using the string split() method of JavaScript and we will use the same here.
Let’s say our file path is −
"/app/base/controllers/filename.js
Following is the code to get file name from string path −
Example
const filePath = "/app/base/controllers/filename.js";
const extractFilename = (path) => {
const pathArray = path.split("/");
const lastIndex = pathArray.length - 1;
return pathArray[lastIndex];
};
console.log(extractFilename(filePath));Output
The console output for this code will be −
filename.js
