# Progressive Web Application (PWA)

> **Definition:** A Progressive Web Application (PWA) is a type of application software delivered through the web, built using common web technologies including HTML, CSS, and JavaScript, designed to work on any platform.

## In depth

PWAs allow developers to build web apps that look and feel like native mobile apps. By utilizing Service Workers, PWAs cache assets and data locally, enabling offline operation. When a user loses internet access (e.g., in a remote farm or warehouse), the app records transactions locally and syncs them automatically once reconnected.

## How ERPStack applies this

We build offline-first PWA dashboard consoles for logistics and field operation teams, ensuring continuous activity logging even without network connections.
