Axios Network Error

Android error image.

Trying to figure out what the hell was going on with a axios get request, I discover by axios – npm documentation a better or more complete way tho handle with error.

This is how:

axios.get(/user/12345)
  .catch(function (error) {
    if (error.response) {
      // The request was made and the server responded with a status code
      // that falls out of the range of 2xx
      console.log(error.response.data);
      console.log(error.response.status);
      console.log(error.response.headers);
    } else if (error.request) {
      // The request was made but no response was received
      // `error.request` is an instance of XMLHttpRequest in the browser and an instance of
      // http.ClientRequest in node.js
      console.log(error.request);
    } else {
      // Something happened in setting up the request that triggered an Error
      console.log(Error, error.message);
    }
    console.log(error.config);
  });
If we log just the error, it will display just the Network Error message on log.
By the way the error was this one: “_response”: “java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.”,
I was trying to access a https local server. I resolved by change the protocol of the req to http.
Hope I can help!

Javascript is awesome

I’m very excited about studying Javascript on the mission of expand my knowledges at front-end. The principal goal is use Javascript at my Java back-end projects.

So, two things I really liked on javascript so far is:

  1. template string;
  2. spread operator.

The first concept lets a array be used as params of methods, on a very easy and functional way.

The second one helps on format messages that uses dynamics values, as variables. We can just reference the value inside a string pattern, marked with the ` character.

See the example…
