Update/Fix PWA Functionality

[thkruz]

User Story

• As a Keep Track user
• I want the application to run offline using a serviceWorker
• So that I can access and use the application even without an active internet connection.

Acceptance Criteria

• Given I am a user of the Keep Track application,

• When I access the application without an internet connection,

• Then the application should load using a serviceWorker enabling offline functionality.

• Given I am using the application in offline mode,

• When I interact with the application,

• Then I should receive a clear notification that I am viewing a cached version of the site.

Tasks

• Research and choose an appropriate serviceWorker implementation strategy for offline functionality.
• Implement the serviceWorker in the Keep Track application.
• Develop a mechanism to detect offline status and inform the user they are viewing a cached version.
• Test the application in both online and offline modes to ensure consistent functionality.
• Document the implementation details and usage instructions for the offline mode.

Commentary

This enhancement will significantly improve user experience by allowing access to Keep Track under various network conditions. Care should be taken to ensure that the offline mode offers a seamless experience and that users are adequately informed about the offline status and any limitations thereof. Implementation should focus on reliability and user-friendliness.
