AWS is offering AppSync – Build data-driven apps with real-time and off-line capabilities


  • AWS AppSync is a fully managed serverless GraphQL service for real-time data queries, synchronization, communications and offline programming features.
  • With AppSync developers can simplify the retrieval and manipulation of data across multiple data sources with ease, allowing them to quickly prototype, build and create robust, collaborative, multi-user applications.
  • AppSync keeps data updated when devices are connected, but enables developers to build solutions that work offline by caching data locally and synchronizing local data when connections become available.
The GraphQL Proxy passes the client request to the Resolver which maps and executes the request payload against pre-configured AWS data services like an Amazon DynamoDB table, an AWS Lambda function, or a search capability using Amazon Elasticsearch. The Resolver executes calls to one or all of these services within a single network call minimizing CPU cycles and bandwidth needs and returns the response to the client.

AWS AppSync is currently in Public Preview.

Could be a very flexible competitor for the Google Firebase realtime database!

How to link to TestFlight App in iOS

There are two things you need to do. First, check to see if TestFlight is installed. Then create a new link to your app. NSURL *customAppURL = [NSURL URLWithString:@"itms-beta://"]; if ([[UIApplication sharedApplication] canOpenURL:customAppURL]) {     // TestFlight is installed     // Special link that includes the app's Apple ID     customAppURL = [NSURL URLWithString:@"https://beta.itunes.apple.com/v1/app/978489855"];      [[UIApplication sharedApplication] openURL:customAppURL]; } This special https://beta.itunes.apple.com URL will be opened directly in TestFlight. Finally, if you are using iOS 9 (or later), you need to make an addition to your Info.plist to get the canOpenURL: method to work. If your app is linked on or after iOS 9.0, you must declare the URL schemes you want to pass to this method. Do this by using the LSApplicationQueriesSchemes array in your Xcode project’s Info.plist file. For each URL scheme you wan...

Server-driven UI (SDUI): Meet Zalandos AppCraft and AirBnB Lona

A short WTF: Joe Birch:  SERVER DRIVEN UI, PART 1: THE CONCEPT Zalando seems to follow the SDUI principle as well - defining a common design language and construct the screens on the backend while displaying them natively on the clients. They even go one step further; they implemented a mighty toolset to enable non-technical stakeholders to define their own native app screens Compass: Web tooling to create screens and bind data Beetroot: Backend service that combines the screen layout definition with the data Lapis/Golem: iOS/Android UI render engines Crazy cool! Good job, guys (when you do an open-source release?) To even move faster a Flutter based UI render engine implementation was great!
