How to Fix "__dirname is Not Defined" in NodeJs

Encountering the '__dirname is not defined' error in Node.js is common when using ES modules instead of CommonJS. To fix this, you can manually define '__dirname' using 'import.meta.url', switch to CommonJS by removing 'type': 'module' from package.json, or use a bundler like Webpack. These methods ensure your project runs smoothly without the '__dirname' issue.
