In this comprehensive guide, we'll walk you through how to write a login controller in a MERN backend. This video tutorial is part of our ongoing backend series, where we delve into creating robust authentication systems. Unfortunately, due to a technical mishap, some of our previous content was lost, but we're committed to re-recording it for you. The tutorial covers key steps, including setting up routes, generating access and refresh tokens, and validating user credentials using Mongoose in Node.js. We also explore best practices like using async/await for database queries, handling errors gracefully, and securing tokens with HTTP-only cookies. This hands-on approach is ideal for those looking to deepen their understanding of JavaScript and backend logic in the MERN stack. By the end of this session, you'll be better equipped to manage user authentication in your own applications. Don’t forget to join our vibrant programming community on Discord, where over 50,000 developers are ready to help. Stay tuned for the next video, where we'll cover logout features and refreshing tokens. Remember to leave a comment or share this content on social media to support our efforts!
