How do i get the filename in /api/anyApi file ??

[sahilrajput03]

console.log(__filename) // Output: /index.js

What is the work i need to do here..?

Hi, what's wrong with console.log(__filename)?
Next.js API routes are simple nodejs functions and you can use any nodejs functions and variables in it. I just tried to get the name of a file and __filename works just fine ;)

Check the codesandbox here.

@akellbl4 ? I don't think __filename works at all.

[sahilrajput03]

Although, the way i managed to figure out the filename is via

const hello: NextApiHandler = (req, res) => {
  const file_name = req.url;

[akellbl4]

__filename contains just the name of the file.
If you need to have pathname from URL req.url works well.

Not sure when this was updated but I would say _filename provides a lot more information than just the actual filename:

// [slug].ts
export const getServerSideProps = async ({ req }) => {

console.log({ __filename, 'req.url': req.url });
const resultOfLogging = {
  __filename: '/my-next-js-project/.next/server/pages/blog/[slug].js',
  'req.url': '/blog/bargerg',
}
 return {
 };
}

Note I use typescript.

I know this comment section is old, but for me. I use Next.JS + Vercel. With this structure on (app/api/):
api/

• db/
• • addition.ts
• • substraction.ts
• defs.ts

When calling the API from the client side (app/exercises/page.ts), I get this. Litterally can't get the name bc of webpack's dynamic naming hasing or something i suppose

console.log(__filename) // C:\Users\ptdrr\Desktop\Projets\bimowy\.next\server\chunks\[root of the server]__47d6b187._.js
console.log(path.basename(__filename)) // [root of the server]__47d6b187._.js
console.log(path.parse(__filename))
// {
//   root: 'C:\\',
//   dir: 'C:\\Users\\ptdrr\\Desktop\\Projets\\bimowy\\.next\\server\\chunks',
//   base: '[root of the server]__47d6b187._.js',
//   ext: '.js',
//   name: '[root of the server]__47d6b187._'
// }
