What experience do you have working with the legacy technology Magic XPA and migrating to Node.js?
💡 Model Answer
Magic XPA is a low‑code platform that lets developers build enterprise applications using a visual designer and a proprietary scripting language. In my previous role I maintained a legacy Magic XPA application that handled customer onboarding. The main challenges were schema drift, integration with legacy databases, and performance bottlenecks. To migrate to Node.js, I first mapped the business logic from Magic XPA’s scripting language to JavaScript, then built RESTful APIs using Express. I used Sequelize to interact with the existing MySQL database and wrote unit tests with Jest. The migration improved maintainability, allowed us to containerize the services with Docker, and enabled a CI/CD pipeline. I documented the migration process and trained the team on the new stack.
