vue axios catch error

Import the Axios library: Begin by importing the Axios library into your Vue component. This can be done by adding the following line of code at the top of your script section:

import axios from 'axios';

Make an HTTP request: Next, you can use the Axios library to make an HTTP request. You can do this by calling the Axios function and passing in the desired HTTP method (such as GET or POST), along with the URL of the API endpoint you want to communicate with. For example:

axios.get('https://api.example.com/data')

Handle the response: After making the HTTP request, you can handle the response using the .then() method. This method takes a callback function as an argument, which will be executed when the request is successful. Inside this callback function, you can access the response data and perform any necessary operations. For example:

.then(response => {
  // Access the response data
  const data = response.data;

  // Perform operations on the data
  // ...
})

Handle errors: In case the HTTP request encounters an error, you can handle it using the .catch() method. This method takes a callback function as an argument, which will be executed when the request fails. Inside this callback function, you can access the error object and handle the error accordingly. For example:

.catch(error => {
  // Access the error object
  const errorMessage = error.message;

  // Handle the error
  // ...
})

Error handling: In the .catch() callback function, you can perform various actions to handle the error. This can include displaying an error message to the user, logging the error for debugging purposes, or performing any necessary cleanup operations. The specific actions will depend on your application's requirements. For example:

.catch(error => {
  // Display an error message to the user
  console.log('An error occurred:', error.message);

  // Log the error for debugging purposes
  // ...

  // Perform any necessary cleanup operations
  // ...
})

Optional: Use finally: Additionally, you can use the .finally() method to execute code that should run regardless of whether the request was successful or encountered an error. This can be useful for performing cleanup operations or updating the UI. For example:

.finally(() => {
  // Perform cleanup operations or update the UI
  // ...
})

That's it! By following these steps, you can make HTTP requests using Axios in Vue and handle any errors that may occur during the process.
