Protractor wait for async requests

Question

I am working on an application where the data is saved asynchronously while it is being edited. As soon as a specific action is performed, protractor quits the test which leads to unsaved data. How to make protractor wait till all the requests are finished?

You can read this answer on how to use protractor

you can use await with any promise , but for call back function you have to make it a promise as you cannot use await with callback functions

Example:

const readFilePromise = () => {
  return new Promise((resolve, reject) => {
    fs.readFile(filePath, options, (err, data) => {
      if (err) return reject(err)
      resolve(data)
    })
  })
}

so we created a file read promise that resolves only after the call back is resolved

Now you can await it as

await readFilePromise ()
