Best Practices for Integrating a MERN Stack Website with NetSuite

I’m working on developing an external system, potentially using a custom website or the MERN stack (MongoDB, Express.js, React, Node.js), and I need to integrate it with NetSuite. I’m looking for guidance on the best practices for integrating a web application with NetSuite.

Here are some specific points I’m interested in:

1. Integration Approach: What is the recommended approach for integrating a MERN stack website with NetSuite? Are there any established patterns or libraries that facilitate this integration?
2. Authentication and Authorization: How should authentication and authorization be handled between the website and NetSuite? Are there best practices for securely managing access to NetSuite resources?
3. Data Synchronization: What strategies should be employed for data synchronization between the website and NetSuite? Are there tools or frameworks that can simplify this process?
4. Error Handling: How can error handling be effectively implemented to handle issues that may arise during the integration process? Are there common pitfalls to avoid?

Additionally, I would appreciate any recommendations for a technology stack that would work well for this integration. If you’ve successfully integrated a MERN stack website with NetSuite before, I would love to hear about your experiences and any lessons learned.

Thanks in advance for your assistance!
