Return a string to the client from an express post route

I'm attempting to return a dynamically generated string back to the client from an Express post route.

Within the backend, I've set up a post route:

router.post('/', async (req, res) => { 
 try {
  // Here, I perform computations on a succession that results in a new string each time
  const foo = 'string that changes and needs to be sent to the client' 
  
 } catch (error) {
   res.status(500).send(error)
 }
})

On the client side, I'm using axios to send data via a post request:

(async () => {
  try {
    await axios.post('/api/send/', { data })
  } catch (error) {
    console.log(error)
  }
})()

Is there a way for me to receive data back from the route after sending the post request?

I attempted to use res.send() within the post route, but it caused functions on the backend to fail.

Thank you in advance.

Answer №1

router.post('/', (req, res) => { 
try {
    // A series of calculations are performed here that result in a dynamically changing string
    const bar = 'dynamic string to be sent to client' 
    res.send(bar);
} catch (error) {
      res.status(500).send(error)
  }
})

This explanation should be adequate. If not, please provide specific details about the error you are encountering.
