Learn how to modernize an existing ServiceNow application using the Now SDK, Fluent TypeScript, and Claude AI. In this tutorial, we take a legacy ServiceNow app from an instance, pull it into a local VS Code project, transform metadata into clean Fluent TypeScript code, make updates using AI assistance, build the project, and install it back into the ServiceNow instance. This video is especially useful for ServiceNow developers, architects, and teams working with legacy scoped applications who want to move toward a modern, code-first development workflow. In this tutorial, you will see how powerful the ServiceNow SDK can be when combined with AI tools like Claude. Instead of manually reviewing old metadata records, you can convert existing applications into readable TypeScript code, improve them in VS Code, version control them, and redeploy them back to your instance. If you are working with ServiceNow custom apps, legacy scoped applications, Fluent SDK, TypeScript, or AI-assisted development, this workflow can help you build faster and modernize existing solutions more efficiently.
