ReferenceError: Headers is not defined error-CodePudding

I'm tring to use a coin API website for a project, I keep encountering the same error:

var myHeaders = new Headers();
            ^

ReferenceError: Headers is not defined

that's the code in use:

var myHeaders = new Headers();
myHeaders.append("apikey", "the API key is here");

var requestOptions = {
  method: 'GET',
  redirect: 'follow',
  headers: myHeaders
};

const data = fetch("https://api.apilayer.com/fixer/timeseries?start_date=2021-01-01&end_date=2021-12-31", requestOptions)
  .then(response => response.text())
  //.then(result => console.log(result))
  .then(result => result)
  .catch(error => console.log('error', error));

console.log(requestOptions);

CodePudding user response：

Please check this as you should fetch the hearers first.

const fetch = require("node-fetch");

var myHeaders = new fetch.Headers();
