Smooth Sailing with Vite: A Guide to CORS Error Prevention in React Development with Vite Proxy

When developing a MERN stack application, you may encounter the CORS origin error. Fortunately, there is a straightforward solution for this issue. Follow these steps:

1. Open your vite.config.js file.
2. Add the following configuration to enable proxying for your API requests:

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

export default defineConfig({
  server: {
    proxy: {
      '/api': 'http://localhost:5000',
    },
  },
  plugins: [react()],
});

By configuring the Vite server to proxy requests, you can avoid CORS issues during development.

Utilize Axios to make your API requests within your React component. Here’s an example using the useEffect hook:

import React, { useEffect } from 'react';
import axios from 'axios';

const YourComponent = () => {
  useEffect(() => {
    const fetchData = async () => {
      try {
        const response = await axios.get('/api/v1/users');
        console.log(response.data);
      } catch (error) {
        console.error('Error fetching data:', error.message);
      }
    };

    fetchData();
  }, []);

  // ... rest of your component code
};

export default YourComponent;

This snippet demonstrates how to use Axios to fetch data from your API endpoint. By combining these configurations, you can resolve CORS issues and streamline the process of making requests within your MERN stack application.
