海外TECH	DEV Community	Supercharge Your Website Using PWA: Background Sync	https://dev.to/ruppysuppy/supercharge-your-website-using-pwa-background-sync-1m23	Supercharge Your Website Using PWA Background SyncThis is a continuation of the previous blogs on adding background synchronization you are highly encouraged to check out the previous blogs before continuing Getting StartedWe would be required to make a request for some external resource from the web like data fetch or post as without that any website by default works offline Let s create a form whose input is submitted to a mock server NOTE This is a continuation from the previous blog where the manifest amp service worker have already been added lt form id email form gt lt input type email id email input gt lt br gt lt br gt lt button type submit gt Submit lt button gt lt form gt Converting IndexedDBThe default behavior of IndexedDB uses a lot of callbacks I personally prefer using Promise Let s add a Promised based wrapper for ease of use const DB NAME background sync db const DB VERSION const STORE NAME unsent requests store const IDB initialize return new Promise resolve reject gt Create a new DB const request indexedDB open DB NAME DB VERSION request onupgradeneeded function request result createObjectStore STORE NAME resolve request onerror function reject request error getByKey key return new Promise resolve

be requiring parts of the above snippet so you may use only the required part in the corresponding file or make a separate script and add it to the service worker using importScripts and the HTML body Registering Background Sync taskWe need to store the data in the IndexedDB before registering the background sync task so that the data can be accessed after the internet connection is re established in case the user is not connected to the web If the browser being used doesn t support background sync there is no point storing it in the IndexedDB as it cannot be synced later we directly send the request in this case script jsconst emailForm document querySelector email form const emailInput document querySelector email input IDB initialize emailForm addEventListener submit async e gt e preventDefault const data email emailInput value emailInput value if serviceWorker in navigator amp amp SyncManager in window amp amp indexedDB in window storing the data in indexedDB await IDB

JSON stringify data headers Content type application json charset UTF const jsonData await response json console log FORM submitted sync not supported console log RESPONSE jsonData Handling the background sync in service workerSince we stored the data in IndexedDB we will be fetching data from the DB and sending the requests If the request fails sync triggered by registering the sync task you should throw an error to ensure its automatically registered for sync when the connection is re established sync handlerconst syncEmails async gt const keys await IDB getAllKeys for const key of

addEventListener sync function event console log SYNC sync event triggered event waitUntil syncEmails then gt console log SYNC Success catch err gt console log SYNC Error throw err If you have multiple sync registrations eg sync emails sync data etc you can use switch event tag to handle each type of sync event CaveatsSome things to keep in mind To go offline you have to physically cut your connection to the internet eg turn off wifi and not use offline mode from dev tools Access to background sync is still limited around of the devices The sync executes only when the service worker
