i think the problem is my fetch is a local host. can you pls help me how do i make the local host in public?

ngrok will allow you to tunnel a port on localhost out to the public Internet. It's not hard for an experienced dev to operate, but it sounds like you might be less experienced. In the long term you need your API server to be running on a machine outside of your LAN. If you're using Next.js for your API server, it will be running on whatever hostname Vercel gives you. Connect to that host rather than localhost. Without knowing more about your architecture, it's difficult to diagnose this & give suggestions.

i use render to deploy my api so i can use this url in my front end but then i encounter this issue Access to fetch at 'https://restaurant-recipe-1.onrender.com/gallery' from origin 'http://localhost:3000' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header has a value 'http://localhost:5173' that is not equal to the supplied origin. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. in server.js i already have this

 app.use(cors({
    origin: ['http://localhost:3000', 'http://localhost:5173'],
    methods: ['GET', 'POST', 'PUT', 'DELETE'],
    credentials: true, // if you need to send cookies with the request
}));
and configured also the proxy
import { fileURLToPath, URL } from 'node:url';
import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
import vueJsx from '@vitejs/plugin-vue-jsx';

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue(),
    vueJsx(),
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  },
  server: {
    proxy: {
      '/api': {
        target: 'https://restaurant-recipe-1.onrender.com',
        changeOrigin: true,
        rewrite: (path) => path.replace(/^\/api/, ''),
      },
    },
  },
});
so in my front end i use this 
fetch('https://restaurant-recipe-1.onrender.com/gallery')
          .then(response => {
            if (!response.ok) {
              throw new Error(`HTTP error! Status: ${response.status}`);
            }
            return response.json();
          })
          .then(data => {
            gallery.value = data.data.gallery;
          })
          .catch(error => {
            console.error('Error fetching data:', error);
          });

 app.use(cors({
    origin: ['http://localhost:3000', 'http://localhost:5173'],
    methods: ['GET', 'POST', 'PUT', 'DELETE'],
    credentials: true, // if you need to send cookies with the request

To format your code blocks, use three backticks at the start and end of your code block. You can also add the language like

```css
.mycode {...}

```css
.mycode {...}

```

You see on the second line where you're setting the CORS origins? Add your Render server there.
