OAuth 2.0 is an industry standard for “delegated authorization” which is the ability to provide an application or client access to data or features offered by another app or service. OAuth 2.0 focuses on authorization and is not prescriptive about authentication. OpenID Connect (OIDC) adds a standards-based authentication layer on top of OAuth 2.0.
In this post, we will cover the fundamentals of OAuth 2.0 and OIDC for authentication and authorization. I will discuss two common flows, namely the Implicit Flow and the Authorization Code Flow.
Couchbase Lite is a full-fledged NoSQL JSON document database for mobile and desktop applications. Couchbase Lite’s Predictive Query API allows applications to leverage pre-trained, Machine Learning(ML) models to run predictive queries against data stored in application's local Couchbase Lite database in a convenient, fast and always-available way. These predictions can be combined with predictions made against real-time data captured by your app to enable a range of compelling applications.
In this post, I provide an overview of the feature including context around why we built it and the kinds of applications that it can enable. I also demonstrate the use of the Predictive API with an example.
Couchbase Mobile enables a wide range of offline-first use cases of varying degrees of scale and complexity. In an earlier post, I discussed common patterns while using Couchbase Lite as an embedded NoSQL data store within your apps. Those patterns focused on local data storage. In this blog post, we discuss a few common patterns and best practices as it relates to syncing data with the Sync Gateway. This post assumes that you are familiar with the fundamentals of Couchbase Mobile. If you need a primer, check out the docs on Couchbase Lite and Sync Gateway.

Pattern 1: Keeping the Data Up-to-Sync While the App Is in the Background
Backgrounding support on mobile apps varies drastically by the platform. In fact, on certain platforms such as Android, the concept of “backgrounded apps” is quite nebulous/complicated. So how you would sync data while your app is in the background is very much platform-dependent. You can find a discussion on how Couchbase Lite reacts to the app life cycle on iOS, Android, and Windows in our documentation.
