Offline Image Viewer

In this project, we'll build a simple web application that allows users to provide image links to store them for offline viewing.

The app aims to improve the offline capabilities of a basic image-viewing application. Currently, the app is unusable offline because it fails to load the page and display images. This project will teach us how to leverage service workers to cache critical assets and improve users' offline experience.

The project is divided into two main tasks. In Task 1, we'll register a service worker and ensure the main application page loads offline. Then, in Task 2, we'll cache images as they're initially fetched so they can be retrieved later offline. Here, we'll work with the Cache API to store image responses. Finally, the app will display cached images when a user loads the page.

By completing these tasks, the image viewer app will be fully functional while offline. Users will be able to at least view images they had seen online earlier. This demonstrates how service workers are used to provide apps with offline capabilities using caching strategies. From completing this project, we'll gain the skills to make progressive web apps more reliable and high-performing for users with poor or limited connections.
