README
The wit_pwamanifest extension facilitates the management of manifest data to generate a Progressive Web App (PWA). This documentation outlines the installation process and provides details on the configuration options for managing the PWA manifest.
Compatibility
TYPO3 13.4 - 14.x.
Installation
Install this extension via composer req woit/wit-pwamanifest and activate
the extension in the Extension Manager of your TYPO3 installation.
TypoScript integration
TYPO3 13+ sites configure TypoScript via Sets rather than static includes.
This extension ships a Set (Configuration/Sets/WitPwamanifest) that provides
the manifest endpoint and the <link rel="manifest"> tag.
Add it to your site's config.yaml:
dependencies: - woit/wit-pwamanifest
Configuration
Go straight to Site Configuration in your TYPO3 backend and edit your page.

The Basic Manifest section provides essential settings for configuring the appearance and behavior of your Progressive Web App (PWA). The setting includes Short Name, Name, Scope, ID, Display, Background Color, Theme Color, Description, and Start URL.
PWA Manifest Icons
This screenshot showcases the PWA manifest icons configuration, which includes settings for small and large icons. Each icon requires the path, type, and size.
TYPO3 sites don't allow inline TCA, so we've created a separate configuration for shortcuts & screenshots.
Shortcuts
The Shortcuts Configuration section provides options for configuring shortcuts that enhance the user experience on your Progressive Web App (PWA). Each shortcut includes the following parameters: Name (Required), Short Name, Description, URL (Required), Icon Size, Icon Source
Screenshots
The Screenshots Configuration section provides options for configuring screenshots that enhance the user experience on your Progressive Web App (PWA). Each screenshot includes the following parameters: Source, Type, Sizes, Form Factor
Upon completing the essential site configuration, the final step is to seamlessly integrate this extension into your TYPO3 template. By doing so, the extension will automatically activate and incorporate the configured manifest data, enhancing the overall performance and user experience of your website.
Offline support / Service Worker
Enable "Enable service worker / offline support" in Site Configuration to register a minimal service worker on the frontend. It caches one offline fallback page and serves it whenever a page navigation fails due to no network connection. It does not cache other assets or pages.
- Enable service worker / offline support – toggles the feature on/off.
- Offline fallback page – the page shown while offline. Falls back to
the manifest
start_url(or/) if left empty.
The service worker script is served through the same typeNum-based
endpoint mechanism as the manifest (?type=836), with a
Service-Worker-Allowed: / response header, which grants it control over
the entire site (scope: '/') despite not being served from a literal
/service-worker.js path. No RouteEnhancer or docroot changes are required.
This is intentionally minimal - no asset caching, no configurable caching strategy, no versioned multi-cache setup. It only makes the site installable with a working offline fallback.
