COMMON POWERUp 2026

Node.js empowers IBM i developers to build modern web services and APIs, leveraging a vast ecosystem of ready-to-use packages via npm (Node Package Manager). This session introduces Node.js through an RPG perspective, demonstrating a simple web service that queries a physical file on IBM i using the idb-connector module and serves JSON data to a browser. The instructor will showcase Node.js basics, compare them to RPG concepts like subprocedures and file operations, and deploy the service on IBM i. No prior Node.js experience is required, but it would be helpful to have a basic understanding of JavaScript (as covered in the preceding JavaScript 101 session). Topics for this session will include Node.js setup, modules, asynchronous programming, Express.js for web services, the benefits of npm’s extensive package repository, and deployment steps. Attendees will receive a handout with code, setup instructions, and resources for further study.

Learning Objectives:

• Understand Node.js, its relevance for RPG developers, and the power of npm’s vast library of packages for rapid development. • Learn how to use idb-connector to access IBM i database tables and serve data via a web service. • Gain insights into Node.js setup, coding, and deployment on IBM i, with resources for continued learning.
