What are the best practices for using Axios in Nuxt.js?

When using Axios in Nuxt.js, it's best to set it up in the context of the Nuxt framework to leverage its features. Here are some best practices:

1. Use the Axios module: Install the Nuxt Axios module for better integration.
2. Set base URL: Configure a base URL in your Nuxt config to avoid repeating it in every request.
3. Use async/await: Handle asynchronous requests with async/await for cleaner code.
4. Error handling: Implement global error handling to manage API errors effectively.
5. Store responses: Use Vuex to store API responses for better state management.

How do I set up the Axios module in my Nuxt project?

To set up the Axios module in your Nuxt project, follow these steps:

1. Install the module using npm or yarn:

   npm install @nuxtjs/axios
   

2. Add @nuxtjs/axios to the modules section of your nuxt.config.js:

   modules: [
     '@nuxtjs/axios',
   ],
   

3. Configure the base URL in the same file:

   axios: {
     baseURL: 'https://api.example.com',
   },
   

4. Now you can use Axios in your components and pages!

What should I do for error handling with Axios?

For error handling with Axios in Nuxt.js, you can set up a global interceptor. Here's how:

1. Create a plugin file, e.g., plugins/axios.js:

   export default function ({ $axios, redirect }) {
     $axios.onError(error => {
       const code = parseInt(error.response && error.response.status);
       if (code === 400) {
         // Handle bad request
       } else if (code === 404) {
         redirect('/404');
       } else if (code === 500) {
         // Handle server error
       }
     });
   }
   

2. Register the plugin in nuxt.config.js:

   plugins: ['~/plugins/axios.js'],
   

This way, you can manage errors globally.
