Integrating Mailchimp API in a Vite React Application

This guide explains how to integrate the Mailchimp API into a Vite React application to automate email marketing strategies. The integration involves creating a form that triggers an API call to Mailchimp when a user clicks the submit button. The prerequisites for this guide include a basic understanding of React, Node.js, and Vite, as well as a Mailchimp account. The suggested folder layout separates the frontend (Vite React app) and backend (Node.js server) into two separate directories. To start, you need to obtain your Mailchimp API key, list ID, and server prefix from your Mailchimp account. Next, you set up a separate Node.js project in the backend directory and install the required packages, including express, @mailchimp/mailchimp_marketing, dotenv, and cors. The backend code creates an endpoint to handle form submissions and makes an API call to Mailchimp to add a new list member. On the frontend, you create a function to handle form submissions and make a POST request to the backend endpoint. Finally, you set up environment variables in a .env file and start both servers using concurrently.
