How can i get the full url in a Nuxt plugin?

Obtaining the full URL in Nuxt.js typically involves using Nuxt's context object. Each plugin function in Nuxt has context as its first parameter, which includes various useful properties and methods, such as req (server-side request object) and route (current route information).

To obtain the full URL in a Nuxt plugin, we can combine the protocol and host information from the req object with the path information from the route object. Here's an example of how to obtain the full URL in a server-side plugin:

1. Create a plugin file: In the plugins directory, create a JavaScript file, for example, full-url.js.

2. Get the URL: Write the following code to construct the full URL:

   javascript
   export default function (context) {
     // Execute only on the server side
     if (process.server) {
       const { req, route } = context;
   
       // Get the protocol (typically http or https)
       const protocol = req.headers['x-forwarded-proto'] || 'http';
   
       // Get the hostname
       const host = req.headers.host;
   
       // Get the full path
       const fullPath = route.fullPath;
   
       // Construct the full URL
       const fullUrl = `${protocol}://${host}${fullPath}`;
   
       // You can perform actions here, such as logging or setting environment variables
       console.log('The full URL is:', fullUrl);
     }
   }

3. Register the plugin in nuxt.config.js: Ensure that the plugin path is added in the configuration file to ensure it is loaded correctly:

   javascript
   export default {
     plugins: [
       '~/plugins/full-url.js'
     ],
     // Other configurations...
   }

By following these steps, whenever the Nuxt application renders on the server side, this plugin will output the full URL of the current request. This is very useful for SEO optimization, logging, or performing specific redirects on the server side. For example, you can decide to redirect to other pages or perform other logic based on certain parameters of the full URL.
