fetch response.json() gives responseData = undefined

Question

When using fetch:

  fetch(REQUEST_URL, {
      method: \'get\',
      dataType: \'json\',
      headers: {
        \'Accept\': \'application/json\',
             


        

Answer 1

fetch(weatherIng + zipCode +apiKey)
        .then(response => response.json())

      .then(response => {
     console.log(response.main);
     this.setState({
       weather: ((response.main.temp * (9/5))-459.67).toFixed(0),
       humidity:((response.main.humidity * (9/5))-459.67).toFixed(0)
     })

It will think that you are trying to declare something if you don't enclose it in its own:

  .then(response => {
     console.log(response.main);
     }) . " around the this.setState
