Service worker exports

offlibrary/sw

import { offlibrarySW } from 'offlibrary/sw';
offlibrarySW();

Export	Description
offlibrarySW(options?)	Installs the handlers. Options: serve (default true), onComplete(item, event), onFail(item, event), onClick(item, event) (return true to skip the default focus/open). Call it at the top level, before your other fetch listeners.
matchOfflibrary(request)	Promise<Response | undefined>: the stored file for a request, with Range handled. Use it in your own routing.
isOfflibraryRequest(request)	Synchronous: would Offlibrary answer this request? Stored URL, or media/Range while the index loads after a worker start.
handleBackgroundFetchEvent(event, options?)	Handles one backgroundfetch* event. Resolves false for IDs that aren’t Offlibrary’s, so you can chain your own handling.
createRangeResponse(response, rangeHeader) / parseRange(header, size)	The Range helpers on their own.
verifyIntegrity(blob, sri)	The SRI check.
OfflibraryError	The error class.

Without a bundler: importScripts('https://cdn.jsdelivr.net/npm/offlibrary@0/dist/offlibrary-sw.iife.js'), then offlibrary.offlibrarySW().

offlibrary/workbox

offlibraryMatch	Workbox route match callback: true for stored files (plus media/Range requests while the index loads after a worker start).
offlibraryHandler({ fallback })	Workbox route handler: the stored file (200/206), else fallback (any strategy or handler; default fetch).
new OfflibraryPlugin({ serveFromCache, fallbackOnError })	Workbox plugin: cachedResponseWillBeUsed and handlerDidError.
initOfflibrary(options?)	offlibrarySW({ ...options, serve: false }).
