Keeping it simple with microservices communication

The term microservice has been getting a lot of hype and attention. I have to admit that I fail to understand what’s the big deal about it. The best practices about microservices are similar to the ones we should apply to everyday software design. Avoid tight coupling. Single responsibility principle. Keeping things simple. Even those principles go back to the old Unix mantra of doing one job and doing it well (and that’s from 1978). And even that could in turn be labelled just “common sense”.

Validate filename conventions with Maven Enforcer plugin

In this post I’m using the Maven Enforcer plugin to break the build when certain files don’t follow the expected naming convention. It’s always a good idea to take the time and implement these checks inside the build pipeline. The alternative is hoping that code reviewers will spot the problems, which is a manual, tedious and error prone approach. Automate all the things!

Fun project: HipChat integration with AWS Lambda

TL;DR: I made a hobby project that gets the pull requests that still need code reviews from Bitbucket and posts a notification message on HipChat to inform developers. It’s written in JavaScript (nodeJS). Travis CI automatically deploys it to AWS as a Lambda function. AWS CloudWatch is used to trigger the function hourly.

Publishing my first Maven package with Travis

A little bit more than a month ago, I created an improved Maven archetype project. Similar to the default quickstart archetype, but for Java 8 and with recent jUnit dependency. In order for someone to use it, they’d have to clone the repo, as I had not published it in Maven. After a bit of studying, I figured out what is needed to make the package public. More importantly, I implemented the process in Travis, so that a new version gets published automatically.
