Dealing with net::ERR_CONNECTION_REFUSED in Axios on a Vue.js platform

Dealing with net::ERR_CONNECTION_REFUSED in Axios on a Vue.js platform

Here's the code I'm using for my connection request:

doLogin(this.login).then(response => {
        var token = response.data.token;
        localStorage.setItem('AUTH_TOKEN', JSON.stringify(token));
        this.$router.push({name: 'Devices'});
        });
      }).catch(error => {
        console.log(error.response.data.message);
      });

The catch() part is effective in handling HTTP errors (like 400, 404, 403, etc.). However, when the server is offline, the script throws a net::ERR_CONNECTION_REFUSED error. Is there a way to handle this error and inform the front-end user that the server is currently offline?

Just in case, here is the doLogin() function:

function doLogin(data) {
  const url   = 'http://localhost:3000/authenticate';
  return axios.post(url,data);
}

javascript vue.js axios

Answer №1

Consider implementing the following code snippet within the catch block:

catch(error => {
        if (!error.response) {
            // handle network errors
            this.errorMessage = 'Error: Network Issue';
        } else {
            this.errorMessage = error.response.data.message;
        }
      })

You have the option to utilize interceptors:

axios.interceptors.response.use(
    response => {
        return response
    },
    error => {
        if (!error.response) {
            console.log("Ensure that your internet connection is working properly.");
        }

        return Promise.reject(error)
    }
)

It is important to perform the validation mentioned by @chithra within the .then() block. I have encountered an unusual problem while testing requests when my servers are down, where the "response" appears to be successful.

Furthermore, ensure that within the .then() block, you check for response.status instead of response.error

Utilizing interceptors is a powerful tool

Custom Interceptors

yourCustomInstance.interceptors.response.use(
  response => response,
  error => {
      if (error.code === 'ERR_CONNECTION') {
          alert("Connection lost");
      }


      return Promise.reject(error)
  }
)

Utilizing npm as the standard package manager for Node.js, a JavaScript runtime environment.

To install Axios using npm:

npm i axios

After installation, ensure to import Axios in your src/App.vue file

import axios from 'axios';

You will then need to invoke it within a lifecycle hook. In this example, we are utilizing the beforeCreate() lifecycle hook so that we can access sensitive data and active events associated with it.

 data() {
return {
  network: false,
}; },
beforeCreate() {
axios
  .get("http://localhost:13172/api/product/getproducts")
  .then((response) => {
    console.log(response);
    this.network = true;
  })
  .catch((error) => {
    console.log(error), (this.network = false);
  }); }
