AWS SNS Push Notifications

Matt McCandless AWS, Cloud, Java, Problem Solving, Technology Snapshot Leave a Comment

Have you ever received endless notifications from the latest application you just downloaded? For example, a bank application that tells you your balance is less than $50. It is likely a message sent directly to your phone through Apple Push Notification Service, Firebase Cloud Messaging, or some other like service.

While you can use any of these services directly, there is a lot to gain by using something like AWS SNS to manage, send, and organize your notifications.

In this post, we show an example of the Push Notification feature of Amazon Simple Notification Service (SNS) using Firebase to handle the iOS and Android messages. Code examples are in Java using Eclipse.

Do note that this blog is solely focused on Push Notification feature of SNS. Keep in mind that SNS can be used for email and SMS messaging, but for brevity, we will steer clear of those.

Generate Strongly Typed React Components with GraphQL

Mat Warger AWS, GraphQL, JavaScript, Programming, Technology Snapshot 1 Comment

When developing in React, using a type system (like Typescript or Flow) can be a great help. You can be sure that your props and state are what you expect, at build-time, and code your components to match.

But what happens when you’re calling to an API to fetch some data, and the shape of that data is what really matters? Maybe the data get passed as props to a child component? You can create types for this, sure, but are they correct? Probably not! Or at least, probably not for long! Things change. Wouldn’t it be great if your types changed too?

In this post, we’re going to take a simple component from zero type awareness to fully typed, with local variables and GraphQL queries included, with a simple workflow. Grab a cup of coffee and a snack, and let’s see how this we can use GraphQL to generate type-safe components in React.

AWS AppSync with Lambda Data Sources

The power of GraphQL lies in its flexibility. That is especially the case regarding resolvers, where any local or remote data can be used to fulfill a GraphQL query or mutation.

In this post, I’m going to demo a quick example of what this looks like, and a couple gotchas that were apparent in working with Lambdas as a data source for AppSync. Let’s gooooo!
