What are the best practices for using Axios in Vue 3 with TypeScript?

When using Axios in Vue 3 with TypeScript, consider the following best practices: 1. Create a dedicated Axios instance for better configuration management. 2. Use TypeScript interfaces to define the shape of your API responses. 3. Handle errors gracefully with try-catch blocks or Axios interceptors. 4. Keep your API calls organized by creating a service layer.

Can you explain how to create a dedicated Axios instance?

Sure! You can create a dedicated Axios instance by importing Axios and using axios.create(). For example:

import axios from 'axios';

const apiClient = axios.create({
  baseURL: 'https://api.example.com',
  headers: {'Content-Type': 'application/json'}
});

This allows you to set default configurations for all your requests.

How do I handle errors using Axios interceptors?

You can set up interceptors to handle errors globally. Here's an example:

apiClient.interceptors.response.use(
  response => response,
  error => {
    // Handle the error
    console.error('API call failed:', error);
    return Promise.reject(error);
  }
);

This way, you can manage errors in one place.

What about using TypeScript interfaces for API responses?

Using TypeScript interfaces helps ensure type safety. For instance, define an interface for your response:

interface User {
  id: number;
  name: string;
  email: string;
}

Then, you can use it in your API calls to ensure the response matches the expected structure.
