Function for checking API status

I'm currently working on an IF statement that will check for results from two API call functions and terminate when it receives results.

function fetchYelp() {
let token = '<token>';
axios.get('https://api.yelp.com/v3/businesses/search?term=Church on the rock&location=saint peters, MO 63376',{
    headers: {
        Authorization: 'Bearer ' + token
    }
})
    .then(res => {
        console.log(res.data);
    })
    .catch(err => {
        console.log(err)
    });

}

fetchYelp();

function fetchWhitePages() {
axios.get('https://proapi.whitepages.com/3.0/business?api_key=<apiKey>&address.city=Saint Peters&address.country_code=US&address.postal_code=63376&name=Church on the rock')
    .then(res => {
        console.log(res.data);
    })
    .catch(err => {
        console.log(err)
    });

}

fetchWhitePages();

I've hit a roadblock.

Answer №1

At the moment, you are not actually returning anything in your code, just logging data when the function is called.

Here is an illustration:

function fetchYelp() {
  let token = '<token>';

    axios.get('https://api.yelp.com/v3/businesses/search?term=Church on the rock&location=saint peters, MO 63376',{
        headers: {
            Authorization: 'Bearer ' + token
        }
    })
    .then(res => {
      if (!res.data) {
        // It is advisable to handle this situation gracefully and return a value indicating no data, as just returning here will exit the function.
        return;
      };

      return res.data
    })
    .catch(err => {
        console.log(err)
    })
};

ESNext using async/await:

async fetchYelp() {
  let token = '<token>';

  try {
    const res = await axios.get('https://api.yelp.com/v3/businesses/search?term=Church on the rock&location=saint peters, MO 63376',{
        headers: {
            Authorization: 'Bearer ' + token
        }
    })

    if (!res.data) {
      // You should still return something here, even if it's just an empty object for demonstration purposes
      return {};
    }

    return res.data
  } catch (err) {
    // The throw statement can also act like a return statement
    throw new Error(err)
  }

}
