Hi, I have a large application that uses MySQLi and MySQL. We are planning to add few custom plug-in written in MEAN stack with Node.JS and MongoDB. Before integration, is there any precaution we should consider. Also, if data is shared between MongoDB db and MySQLi, should I create an API to synchronize data or what is best way to achieve that? I have basic knowledge of MongoDB, so I appreciate your advice. -- Cheers, Matt Zand Cell: 202-420-9192 Work: 240-200-6131 High School Technology Services <https://myhsts.org/> DC Web Makers <https://dcwebmakers.com/> Coding Bootcamps <https://coding-bootcamps.com/>
