An Example Progressive Web App on Android

RJ Dela-Cruz AngularJS, JavaScript, Mobile, Technology Snapshot Leave a Comment

In my experience, the best way to learn a new technology is to create something tangible with it. I recently sought out to learn Angular and Angular Material. So, I developed an experimental Angular app that uses omdbapi to query Movie Posters. It’s aptly named Movie Poster Finder.

Developing the Movie Poster Finder application, I ran into a thing called PWA, which is also known as Progressive Web Applications. I thought it was really neat that both Android and mobile Chrome treat them as native applications.

In this post, I will show an example Progressive Web Application in action, explaining what I encountered when turning an experimental Angular web application into a PWA.

The Executable Code Review

Tim Broyles Programming, Testing Leave a Comment

Testing has a bad rap. The thought of writing unit tests to exercise code with the goal of 100% code coverage can be overwhelming for many projects. The number of man-hours to set up tests, create mocks when needed, test boundary conditions, contrive odd ball test cases can take some steam out of the project. If this is the definition of test, then yes, writing these types of tests can be tedious and feel meaningless.

I am a proponent of writing tests with a narrow focus. The tests I describe here show the completion of a story or the resolution of a bug. With this narrowness in mind, the task is much less daunting. My goal now is not about code coverage, but more about quality code. With this test, I want to be able to demonstrate to myself (and to whoever is reviewing my changes), that I have successfully resolved my task.

In this blog I will talk about my suggestions for writing meaningful tests in the context of a code review.



React v16.0 Release Overview and Migration

Luke Curran JavaScript, React, Technology Snapshot Leave a Comment

React v16.0 was released by Facebook on Tuesday, September 26th. This version introduces performance boosts and other very helpful features.

React 16 brings some significant internal changes features to the table. In my opinion, one of the most interesting thing about this release is that React has been rewritten. Luckily, in terms of upgrading, if your app runs in 15.6 without any warnings, it should work in 16 (with minor exceptions).

In this blog I highlight some of the new features introduced in React v16.0, in addition to demonstrating how to update your current React applications to v16.0 using a Keyhole open source application for reference…



Could the Equifax Hack Have Been Prevented by a Microservices Architecture?

David Pitt Architecture, Java, Microservices, Opinion, Security Leave a Comment

When I heard that the Struts Open Source framework played a role in the recent Equifax hack, I wanted to do some research to understand how it happened. Struts is a commonly-used Java framework that I have applied in the past. And I’m not alone in that: it is reported that in 65% of Fortune 500 companies currently implement Struts in some way.

So, I did a little digging and performed a thought experiment asking myself the following question: “If Equifax had a pure-play Microservices Architecture in place, would it have solved the problem?”



Using Docker + AWS to build, deploy and scale your application

Brandon Klimek AWS, Docker, Spring, Tutorial Leave a Comment

I recently worked to develop a software platform that relied on Spring Boot and Docker to prop up an API. Being the only developer on the project, I needed to find a way to quickly and efficiently deploy new releases. However, I found many solutions overwhelming to set up.

That was until I discovered AWS has tools that allow any developer to quickly build and deploy their application.

In this 30 minute tutorial, you will discover how to utilize the following technologies:
– AWS CodeCommit – source control (git)
– AWS Code Build – source code compiler, rest runner
– AWS Codepipeline – builds, tests, and deploys code every time the repo changes
-AWS Elastic Beanstalk – service to manage EC2 instances handling deployments, provisioning, load balancing, and health monitoring
-Docker + Spring Boot – Our containerized Spring Boot application for the demo

Once finished, you will have a Docker application running that automatically builds your software on commit, and deploys it to the Elastic beanstalk sitting behind a load balancer for scalability. This continuous integration pipeline will allow you to worry less about your deployments and get back to focusing on feature development within your application.
