Store custom image http call with Multer in NodeJS

Question

I have HTTP call with Buffer image inside from NodeJS Server 1 (run at localhost:5000) to NodeJS Server 2 (run at localhost:5001)

There are the Server 1 axios call:

await axios.post('http://localhost:5001/', {
  buffer: fileBuffer,
  ...otherData //
})

I read that Multer gets the image from req.files, but in my case they arrive as req.body.buffer

How can i do?

Solved
I haven't used Multer

On Server 2 use Buffer.from() for get Buffer from your http call (because is an JSON array) and then fs.writeFile() or fs.writeFileSync() write file on disk

This is the way I used (Server 1):

await axios.post('http://localhost:5001/', {
  buffer: fileBuffer,
  name: fileName
})

Server 2:

const { body } = req // This is the HTTP object, it contains buffer and name
const data = Buffer.from(body.buffer) // Transform array to buffer value
const path = './public/' + body.name // "./public/sample.jpg"

fs.writeFileSync(path, data) // writeFile and writeFileSync also accept Buffer
