Progressive Web App

Make your site installable and work offline with a manifest and service worker.

Overview

Make your site installable on phones and desktops with a web app manifest and a service worker. App name, short name, description, and icons are prefilled from your WordPress settings and site icon, so a working manifest is usually one click away.

Manifest Settings

Setting	Notes
Name / short name	Prefilled from Settings → General
Start URL / scope	Default /
Display	standalone by default, with optional display_override
Theme / background color	Controls the splash screen and OS chrome
Icons	192px and 512px, each with an optional maskable variant
Shortcuts & screenshots	Richer install prompts on supported platforms
Advanced manifest	Raw JSON merged over the generated manifest

Service Worker

The service worker precaches an offline shell and caches runtime responses, with deliberate exclusions so it never serves something it should not:

• Skips wp-admin, the login page, and REST responses
• Skips cross-origin requests and anything marked no-store or private
• Caps the runtime cache so it cannot grow without bound
• Precaches URLs individually, so one stale or missing URL cannot abort the whole install

Install prompt is opt-in. The custom prompt is off by default. When enabled you control its title, text, button labels, position, style, and how many days pass before a dismissed prompt returns.

Web Share Target

Optionally register your site as a share target, so content shared from the OS share sheet arrives as a search on your site. Values are sanitized and used only to build a safe redirect.
