Deploying a MERN Application to Production

Deployment is the process of making your application available to users. It involves hosting the frontend, backend, and database. The frontend is typically deployed on platforms like Vercel, while the backend can be hosted on services such as Render or AWS. MongoDB Atlas is commonly used for database hosting. It provides a cloud-based solution that is easy to scale. Environment variables should be used to store sensitive information such as API keys and database URIs. CORS must be configured to allow communication between frontend and backend servers hosted on different domains. For example, a production setup may include a React frontend on Vercel and a Node.js backend on Render. In conclusion, proper deployment ensures that your application is secure, scalable, and accessible to users.
