A simple framework for implementing message-based, user-initiated CRUD operations. A message-based microservices architecture offers many advantages, making solutions easier to scale and expand with new services.

Many developers have one of two opinions about unit tests: they believe 100% of the code has to be covered by unit tests, or they believe 100% of the code has to be covered by unit tests but they have reasons for not writing any. It isn’t common to find people who dislike the idea of unit tests. The main cost of having unit tests is spending time to write them.

Docker is a great way to package and deploy web applications. Applications that have been containerized can easily be created, destroyed, or even moved between servers, as long as the servers are using the Docker runtime. Not too long ago I wrote about creating a RESTful API that could process images and generate Android compliant launcher icons. This article was titled, Create an Android Launcher Icon Generator RESTful API with Node.js, and Jimp and it was powered by Express Framework.

When you’re developing an Android mobile application, it is critical that you come up with a nice launcher icon for all possible Android screen densities. If you’re not too familiar with Android, there are mdpi , hdpi , xhdpi , xxhdpi , and xxxhdpi densities as of now. This number could change in the future. Once you’ve got your icon, resampling or resizing it for each possible screen density can become a pain in the butt.
