The error: “__dirname is not defined in Node 14 version” is a common error that can show up in many ways. In this blog, we will go through some of the ways you can fix this issue. Read on.
How To Solve The Error: “__dirname is not defined in Node 14 version”?
When upgrading your node to version 14, you may experience the following issue.
__dirname is not defined
To fix this problem, you must define __dirname as follows: const __dirname = dirname(__filename);. Now, you have resolved your error.
Approach 1:
You must define __dirname as follows:
import { fileURLToPath } from 'url';
import { dirname } from 'path';
const __filename = fileURLToPath(import.meta.url);
const __dirname = dirname(__filename);
Now, you have resolved your error.
Approach 2:
Simply include the following code to define __dirname:
import path from 'path';
const __dirname = path.resolve();
Now, you have resolved your issue.
Approach 3:
What is the way you load your file? This trouble indicates that you are loading it like the way you load an ECMAScript module without __dirname, so the error occurs.
All you need to do is:
import { fileURLToPath } from 'url';
import { dirname } from 'path';
const __filename = fileURLToPath(import.meta.url);
const __dirname = dirname(__filename);
Approach 4:
It is not essential for you to import from ”path” or ”url”.
For example, ESM is being used in this case. Let’s run this command:
fs.readFileSync(new URL('myfile.txt', import.meta.url));
myfile.txt
will be read from the JavaScript file’s directory but not from the present working directory.
