One of my recent projects was to try to identify unused pieces of code and remove them safely. This can be quite a difficult task in Ruby, as there is little way to be certain what calls what.
A solution to this problem of identifying such code is to record all calls for a relatively long period on your production server, and then see what hasn’t been called. …
One of the focus of our engineering team recently was to extract features from our main Rails monolith to different smaller micro-services. One of these tasks was to take care of the UI that is used to create a “Job Post”. This new Single Page App micro-service was developed using React and TypeScript. Since we needed it to support multiple languages (at least Japanese and English for now), I would like to share here the process of translating that UI with the lingui-js library (2.8.3).
Before going into the details I would like to go through some of the motivations…

At that point, we might have hundreds of models/views/partials/controllers etc… and as much places where we can seek improvements. Here we will focus on a specific case of partials rendering.
