Replit, an online text editor and integrated development environment (IDE), simplifies the process of building and deploying Node.js applications by allowing developers to create and manage projects from any device. This article explores Replit's capabilities by constructing two types of Node.js applications—a Discord bot and a to-do app with React—demonstrating Replit's features such as code autocomplete, coding AI assistance, built-in Git support, and hosting services. Replit's deployment feature, introduced in 2023, separates development and production environments, enabling more efficient hosting. The platform also supports importing repositories from GitHub, making it versatile for both new and existing projects. Additionally, Replit's "Always on" feature, though not free, helps keep applications running without interruption, while tools like UptimeRobot can be used as an alternative to maintain app activity. Overall, Replit offers a collaborative and efficient environment for developing and deploying Node.js applications.
