How to get data and response status from API using node-fetch?

As per the node-fetch documentation node-fetch

we can get the response status like this

fetch('https://github.com/')

    .then(res => {

        console.log(res.status);

    });

and for getting the data

fetch('https://api.github.com/users/github')

    .then(res => res.json())

    .then(jsonData => console.log(jsonData));

I have a scenario where I need to return the JSON data and the status from the response. I tried to use like this

     fetch('https://api.github.com/users/github')

            .then(res => res.json())

            .then(jsonData => {

             console.log(jsonData);

             console.log(jsonData.status);

      });

but the

console.log(jsonData.status)

won't return the status. How I can get status and output data

The easiest solution would be to declare a variable and assign res.status value to it:

let status; 

fetch('https://api.github.com/users/github')

  .then((res) => { 

    status = res.status; 

    return res.json() 

  })

  .then((jsonResponse) => {

    console.log(jsonResponse);

    console.log(status);

  })

  .catch((err) => {

    // handle error

    console.error(err);

  });

You can also try it that way using async/await:

const retrieveResponseStatus = async (url) => {

  try {

    const response = await fetch(url);

    const { status } = response; 

    return status;

  } catch (err) {

   // handle error

    console.error(err);

  }

}

Then You can use it with any URL You want:

const status = await retrieveStatus('https://api.github.com/users/github')
