serviceworker

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

The serviceworker member specifies a serviceworker that is Just-In-Time (JIT)-installed and registered to run a web-based payment app providing a payment mechanism for a specified payment method in a merchant website. See Payment Handler API for more details.

Values

serviceworker objects may contain the following values:

scope

A string representing the service worker's registration scope.

src

A string representing the URL to download the service worker script from.

use_cache

A boolean that sets how the HTTP cache is used for service worker script resources during updates. It provides equivalent functionality to certain values of the updateViaCache option provided when a service worker is registered via JavaScript using ServiceWorkerContainer.register().

  • true: The HTTP cache will be queried for imports, but the main script will always be updated from the network. If no fresh entry is found in the HTTP cache for the imports, they're fetched from the network. Equivalent to updateViaCache: "imports".
  • false: The HTTP cache will not be used for the main script or its imports. All service worker script resources will be updated from the network. Equivalent to updateViaCache: "none".

Examples
