Is it considered good practice to make a POST request within a GET request?

Is it considered good practice to make a POST request while also making a GET request in my app? Or is this frowned upon?

In my application, the functionality works like this: when the page loads, it needs to retrieve user data. If the user data is not found in the database, it should be added. There is no sign-up process involved - we are simply keeping track of all users on the site (tracking how many times they've visited and assigning an ID).

UPDATE: We are not storing login information or signing users up; we are only recording the number of website visits in our database.

I attempted to set it up by first making a GET request and then running a POST request upon success, but it seems overly complicated.

export default function handler(req, res) {
  if (req.method === 'GET') {
    // check if user exists in db (db.get())
    // if not, execute a PUT request (db.save())
  } 
}

There could be a more efficient solution available. When working with DynamoDB, you have the option to utilize the UpdateItem method. This feature allows you to update an existing item or create a new one if it doesn't exist. Furthermore, by specifying the ReturnValues parameter, you can retrieve specific attributes upon completion. It's possible that all your requirements can be met with just one of these calls.

If not, the current approach seems satisfactory. To avoid nesting callbacks, you can split the operations using the async and await keywords:

export default function handler(req, res) {
  if (req === "GET") {
    const result = await getRequest();
    if (result.isEmpty()) {
      postRequest();
    }
  }
}
