Returning value from a function in react

Question

When I\'m trying to return my res.data from my function and then console.log it I get undefined but if I console.log it from inside the function I get the normal result

Answer 1

You should return the promise instead.

const getDefaultState = () =>
  axios
    .get("http://localhost:5000/urls/todos")
    .then((res) => {
      if (res.data) {
        console.log(res.data);
        return res.data;
      }
    })
    .catch((err) => console.log(err));

That way you can listen to the result outside the function:

getDefaultState().then(/* do stuff */);
// or
const res = await getDefaultState();

You need to return the call as well:

const getDefaultState = () => {
  return axios.get("http://localhost:5000/urls/todos")
        .then((res) => {
           if (res.data) {
              console.log(res.data);
              return res.data;
           }
  }).catch((err) => console.log(err));
}
