In JavaScript, you can use the import.meta.url property to get the file path of the currently executing module. This property is available in ECMAScript 2021 and is commonly used in Node.js applications. Here is an example:
Say, we have a file named example.js located in /home/user/documents/ directory and the content of the file is as follows:
console.log(import.meta.url); // logs 'file:///home/user/documents/example.js'
Here, the import.meta.url property returns the file path of example.js.
We can also use the URL constructor to get a more structured file path. Here’s an example:
const filePath = new URL(import.meta.url).pathname;
console.log(filePath); // logs '/home/user/documents/example.js'
The URL constructor takes the import.meta.url value and generates a URL object. The pathname property of the URL object can then be accessed to get the file path.
