THE OFFLINE FIRST READER

Issue 3, 15 May 2015

A monthly reader featuring all things Offline First, covering theory, technology and user experience for new offline use cases.

Recent:

The latest issue of the Thoughtworks Tech Radar was released in May and it includes local storage sync and also added offline first web applications as a new topic to be on everybody‘s radar. Hoodie and CouchDB are mentioned as tools to “help simplify offline first implementation” and offer the “ability to work with a locally deployed application on a local data storage”. Also according to Thoughtworks the ”offline-first mindset” plays an important role today. Local storage sync in this context has become a successful technique for e.g. the implementation of offline single-page applications.
The Thoughtworks Tech Radar gives advice especially about new and yet unproven technologies and independent opinions about the ones that have become standards and is released biannually.

Jake Archibald at SmashingConf Oxford 2015: “The UX Of Offline-First” or “Modern Progressive Enhancement”. The release of Service Worker by Chrome is a clear sign that technology is readier than ever to solve more and more problems of network-dependency. We have now reached the point to ask loudly for solutions on the experience side of offline and native apps. (@jaffathecake/@smashingconf)

On April 23 Dropbox announced that it'll soon be deprecating their sync API: “As of today, new Dropbox apps should use our Core API. Over the next six months, we’ll continue to implement urgent bug fixes as needed to the Sync and Datastore SDKs, but we are no longer actively developing them. In October 2015, we will discontinue support for the deprecated SDKs entirely.” - clearly evoking some critical reaction: “Dropbox deprecating their sync API is why you are better off using Open Source solutions for your core infra.” (@janl, CouchDB/Hoodie). Couchbase summarised disappointed user voices and aspects of the controversial decision on their blog. James Nocetini (@jamitz, Couchbase) shows in a video how to switch from Dropbox Datastore to Couchbase Mobile.

ampersand-offline-first 0.014 release: Ampersand.js, ampersand-sync hijack with localForage. A module hijacking the sync in the ampersand-sync method of your Ampersand models and rest-collections. It uses localForage: a JavaScript library that improves the offline experience by using an asynchronous data store with a simple, localStorage-like API.

So Chrome shipped Service Worker, Firefox is “looking busy” and if you don't want to miss any event of the big Service Worker implementations parade you can meanwhile follow them on Twitter. Or look at their general implementation status overview.

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 et.al. for your business, we make sure everything goes well. Get professional CouchDB support:
