Hi, can you provide example for the customAPI call?

task-api-example.js has one. You can add your axios logic there.

For both success and failure cases, It is reaching .then() in all the calling places. Do we need a interceptor to return Promise.reject(error) ?

That is normally an issue with the server, not the JavaScript. Most likely your server is sending back incorrect status codes.

Hi Michael, Thanks for the quick response. I have created a simple react app which fetches list of users and displays it. I have used the above 'api-provider.js' and 'response.js' files to create a service layer. Here When i make a get call to get all the users. I see that the log inside 'then' block is seen.

fetchItems = () => {
  return apiProvider.getAll(url).then(function (userData) {
    console.log('inside then block'); // Control reaches here
    return userData;
  }).catch((error)=>{
    console.log('inside catch block');
  });
};

I am returning 400 error code in my back end. Also the catch block of getAll() function is getting called.

/** @param {string} resource */ 
const getAll = (resource) => { 
  return axios 
    .get(`${BASE_URL}/${resource}`) 
    .then(handleResponse) 
    .catch(handleError);  // Control reaches here
};

Is this the expected behaviour ? How do I make sure that the catch block in the fetchItems function gets called and it does not go inside then?

Looks like this is a feature of the Axios library. You'll probably have to implement your own interceptor for axios or a check to throw certain statuses to your .catch method.
