Service Worker Strategies And Behaviors
A service worker strategy is related to how the
vite-plugin-pwa plugin will generate your service worker, while the behavior of a service worker is related to how the service worker will work in the browser once the browser detects a new version of your application.
Service Worker Strategies
As we mention in Configuring vite-plugin-pwa section,
vite-plugin-pwa plugin will use
workbox-build node library to generate your service worker. There are 2 available strategies,
vite-plugin-pwawill generate the service worker for you, you don't need to write the code for the service worker
vite-plugin-pwaplugin will compile your custom service worker and inject its precache manifest
To configure the service worker strategy, use the
strategies' plugin option with
generateSW (default strategy) or
You can find more information about the strategies in the generateSW or injectManifest
Service Worker Behaviors
The behavior of the service worker will help you to update the application in the browser, that is, when the browser detects a new version of your application, you can control how the browser updates it.
You may want to not bother users and just have the browser update the application when there is a new version: the user will only see a reload of the page they are on.
Or you may want to inform the user that there is a new version of the application, and let the user decide when to update it: simply because you want it to behave that way or because your application requires it (for example, to prevent data loss if the user is filling out a form).
To configure the service worker behavior, use the
registerType plugin option with
prompt (default strategy) value.
You can find more information about the behaviors in the auto-update or prompt-for-update sections for
generateSW strategy or in inject-manifest section for
