How to Add a Postgres Database to Your Replit Agent Project

Replit Agent enhances application functionality by automatically integrating a Neon Postgres database to ensure data persistence, allowing apps to store and retrieve user data across sessions. This feature is crucial for applications like games or habit trackers, where losing user data upon closing the app would diminish their utility. If Replit Agent does not initially add a database, users can prompt it with a simple description of their desired feature, such as a leaderboard for a Snake game, and the Agent will configure the necessary backend and frontend changes. This involves creating a database schema and updating the UI to support the new feature, ensuring that user scores and progress are maintained even after refreshing the browser. By leveraging natural language prompts, developers can guide Replit Agent to enhance their projects with persistent data storage, backed by Neon Postgres databases, which are seamlessly integrated into the development process.
