Announcing Offline Camp Berlin

Building the Offline First community, one campfire at a time.

Offline Camp Berlin

We’re taking the Offline First community for a long weekend of discussion, relaxation, and collaboration in Berlin. It’s sold out already, but be sure to get on the waitlist today to be part of the conversation at Offline Camp Berlin!

While you’re in Berlin for Offline Camp (April 28 – May 1), consider sticking around for lots of awesome What The Fest events throughout the city, including JSConf EU (May 6 – 7).

Send messages when you’re back online with Service Workers and Background Sync – When you send an SMS message but your phone doesn’t have great signal it will continue to try to send the message in the background, even if you close the app. Pretty useful right?

Speed up Service Worker with Navigation Preloads – In some situations, service worker boot-up time can delay a network response. A new experimental feature, navigation preload, fixes this by allowing you to make the request in parallel with service worker boot-up.

Service worker and caching from other origins – For quite some time its been a popular best practice to host resources on other hosts: sub- or alternative domains or maybe third party CDN’s. I won’t go into the good and bad of that practice today, but I will share a challenge (and the solution/options) I’ve found when building an offline app with service-worker and using other hosts.

The first step to a successful offline-first application architecture is a database layer that handles synchronisation in the face of unreliable networks. Apache CouchDB and its family of peers, like PouchDB and Couchbase Mobile, are exactly what you need.

If you rely on CouchDB for your business, we will make sure everything goes well. Get professional support from Neighbourhoodie Software today!
