It illustrates how you can use Couchbase Lite in your mobile apps to share data across devices and among users. If you familiarize yourself with this code, you'll be ready to write your own multi-user interactive data driven applications on iOS. There is a tour of the data model on the wiki. Couchbase Server should be deployed behind your firewall like databases normally are , and then the Sync Gateway should be deployed where it can be accessed by mobile devices from the public internet, and it can reach Couchbase Server.
Mobile devices connect to the Sync Gateway, which enforces access control and update validation policies. Before you can run the app, you'll need to install the Couchbase Sync Gateway and configure it for chat.
Download a copy of the Sync Gateway for your platform from Couchbase's download page. Or you can build it from source if you want. The CouchChat repo contains a configuration file for the gateway, sync-gateway-config. Put the path to the config file on the command line when you launch the gateway. The Gateway needs to know the URL that clients connect to it at, in order for Persona authentication to work properly.
It gets this URL from the persona. It should consist only of the root URL of the server, including the port but without any path or trailing slash.
Deploy your offline-first mobile and embedded applications with greater agility on premises or in any cloud. Deliver an always-on experience, even with spotty networks and dropped connections. Scale from hundreds to millions of users with the flexibility to add capacity at every tier: client Couchbase Lite , middle Sync Gateway , or storage Couchbase Server. Differentiate from other iOS and Android databases with built-in enterprise-grade security for the full stack.
Simplify development with a consistent programming model for building web, desktop, and mobile apps. Secure web gateway that enables data access and synchronization over the web. Elastically scalable in real time, Sync Gateway scales capacity demands as they change throughout the day. Couchbase Mobile supports all major mobile platforms in addition to traditional desktop and server environments. Couchbase Mobile supports all major mobile programming languages.
Aggregate data collected from different sources in one platform to build a single view of your customer or business. This will be populated with the query results. In this case, the document in the result is embedded in a dictionary where the key is the database name, which is "userprofile". So we retrieve the DictionaryObject at key "userprofile". You will need this when you update the document.
This entry holds an array of attachments corresponding to each image blob entry added by the mobile app. This property is added by the Sync Gateway when it processes the document. You can learn more about how image Blob types are mapped to attachments link:[here]. You can choose to update any other profile information. This is a link:[known issue] in 2. Data conflicts are inevtiable in an environment where you can potentially have multiple writes updating the same data concurrently.
Couchbase MObile 2. You can learn more about automated conflict resolution in this blog post. This tutorial walked you through an example of how to use a Sync Gateway to synchronize data between Couchbase Lite enabled clients. We discussed how to configure your Sync Gateway to enforce relevat access control, authorization and data routing between Couchbase Lite enabled clients. We will will cover the basics of the l Sync Gateway Configuration.
Configure your Sync Gateway to enforce data routing, access control and authorization. You can learn more about the Sync Gateway here Prerequisites This tutorial assumes familiarity with building swift apps with Xcode and with Couchbase Lite. If you are unfamiliar with the basics of Couchbase Lite, it is recommended that you walk through the following tutorials Fundamentals of using Couchbase Lite 2.
So you can have multiple versions of Xcode on your Mac. Create a free github account if you don't already have one git can be downloaded from git-scm. Xcode Download Couchbase Lite. Unzip the file Drag CouchbaseLiteSwift.
Import the framework import CouchbaseLiteSwift Use Case 1. Include in Existing Swift Package.
