Overview

Cache Manager is a client-side component for OutSystems applications that simplifies the handling of browser storage. It provides a set of reusable APIs to interact with the browser’s Session Storage in a structured way.

By using Cache Manager, developers can easily set, get, remove, and clear session-based cached data without writing repetitive JavaScript code.

Features

• Set values into session storage (string or JSON format).

• Get values from session storage.

• Remove a specific value from session storage.

• Clear all session storage data in the browser.

• Works across any OutSystems web or reactive application.

Use Cases

• Storing Temporary User Preferences → e.g., filter options, tab states.

• Caching API Responses → e.g., dropdown data that doesn’t change often.

• Managing Authentication Tokens → store session-only JWT tokens.

• Multi-Step Forms / Wizards → preserve input data across steps.

• Reducing Server Load → cache frequently used lookup data.

• Session Flags → e.g., show onboarding only once per session.
