TypoScript

The site set and the static template register the following page types and header data. All endpoints are rendered by WoitWitPwamanifestServicePwamanifestService.

TypoScript object	typeNum / key	Content-Type	Method
`manifest`	835	`application/manifest+json`	`manifestConfiguration()`
`serviceWorker`	836	`application/javascript`	`serviceWorkerScript()`
`page.headerData.999999`	–	–	Renders `<link rel="manifest">`
`page.headerData.999998`	–	–	`serviceWorkerRegistration()`

The service worker response additionally sends the header Service-Worker-Allowed: /.

Note

The service worker URL is built in PHP with the fixed parameter &type=836. If another extension or your site package already uses typeNum 835 or 836, change the conflicting type there.

Resulting URLs

https://example.org/?type=835   Manifest
https://example.org/?type=836   Service worker script

The manifest link always points to the current page with type=835.
