Offline Access (PWA)	plugin/emitter

This plugin allows your website to be accessible offline and be installed as an app. You can use it by adding Plugin.Offline(), to the emitters in quartz.config.ts

Offline Capability

Whenever you visit a page it gets cached for offline use. Depending on the kind of content, the process for caching is diffent:

• Pages (HTML, your converted Markdown files): Quartz first tries to get them over the Network. If that fails, your browser attempts to fetch it from the cache.
• Static Resources (Fonts, CSS Styling, JavaScript): Quartz uses cached resources by default and updates the cache over the network in the background.
• Images: Images are saved once and then served from cache. Quartz uses a limited cache of 60 images and images remain in the cache for 30 days

You can edit the fallback page by changing the offline.md file in the root of your content directory

Progressive Web App (PWA)

Progressive Web Apps can have many properties. We're only going to mention the ones Quartz supports by default, however you can edit the offline plugins file to add more in case required.

• icons: the icon.svg file in the quartz/static directory is used for all the icons. This makes it easier to scale the image since you don't need to provide an png for every size
• name, short_name: Uses the pageTitle configured in quartz.config.ts
• description: Uses the description configured in quartz.config.ts
• background_color, theme_color: Uses the lightMode.light color configured in quartz.config.ts.
• start_url: Uses the baseUrl configured in quartz.config.ts

Default values

• display: this is set to minimal-ui
