AWS Amplify GraphQL Queries with TypeScript and Hooks

Mat Warger AWS, JavaScript, React, Technology Snapshot, Tutorial, TypeScript Leave a Comment

I’m a big fan of Amplify. I’m also a big fan of TypeScript. Amplify is not built with TypeScript, and to use it effectively, sometimes you need to give it a little help, especially when it comes to GraphQL. With the advent of hooks, we can create some nice utilities for ourselves that let us leverage the power of TypeScript with our GraphQL queries. Let’s see what that looks like.

I’ll be assuming familiarity with React and TypeScript, i…

AWS Lambda With NestJS

Greg Emerick AWS, JavaScript, Node, Technology Snapshot Leave a Comment

In my previous blog post, I showed running a Spring Boot Java application in AWS Lambda. I discussed the pros and cons of using Java and Spring with Lambda. In this blog post, I’ll cover another Lambda option with NestJS. NestJS provides a framework that is not too different from a typical Spring application. It also addresses some of the negatives of using Java and Spring in a Lambda function.

To recap, AWS Lambda provides low cost compute with zero maintenance. Lambda runs your code on demand, without provisioned and managed servers. Lambda automatically runs and scales your code. You are charged for every 100ms your code executes and the number of times your code is triggered. Lambda has clear cost and maintenance benefits over typical on-premise or EC2 deployments. What does it take to run a Nest application as a Lambda? Does NestJS provide benefits over a Java Spring application?

Bringing a Microservice Into an AWS App Mesh

Brad Flood AWS, Microservices, Technology Snapshot Leave a Comment

Remember when Netflix first came out with its suite of distributed components? It included Eureka for service discovery, Hystrix for circuit breaking, and Zuul for intelligent routing. Netflix was running on an AWS infrastructure back then, but the infrastructure didn’t exist for Netflix to manage its microservice ecosystem. The industry has come to describe the Netflix components within the larger context of a service mesh.

AWS recently introduced App Mesh, a highly-available set of services that integrate with the AWS ecosystem and provide the capabilities Netflix was looking for back in the day.

In this post, we provide an introduction to AWS App Mesh and show a quick tutorial of bringing a reference microservice into an AWS App Mesh.

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.
