Monorepo in real life
By Yann Braga
Once a project starts to scale, it’s inevitable to not bump into multiple challenges. You start wondering how to share common code like shared apis, component libraries and such.. so what to do next? In this talk we discuss about repository structures and walk through real life use cases, present its pros and cons, as well as show how the monorepo greatly improved development and delivery speed in an enterprise app.
Converting a 20-year-old train ticket vending machine into a modern web app
By Maarten Laurs
Have you ever used a ticket vending machine at a Dutch train station? I bet you did not realize that they are almost 20 years old. They are operated by a proprietary closed source framework written in C++ that is even older and it makes developing software for this platform a real pain.
Adding a simple button to a screen for example, takes hours. Automating user interface testing at a basic level requires a lot of custom code. Things would really be much simpler if the framework’s view layer could be replaced by a web browser and a web application like Angular. But how do you achieve that?
In this talk I will show you how we solved this challenge. Along the way you will learn how the ticket vending machine operates on the software level and how we were able to maintain the original layouts by combining Java, Antlr, Thymeleaf and Angular. I will show you how we bypassed the framework and integrated Electron as a web browser into the machines. You will also learn how switching to open standards enables better testing of the user interface and how this change will
positively affect visually impaired customers. Lastly you will get a glimpse into the future as I will show you how we can decrease the role of the proprietary framework in other parts of the machine.
* Please note that it requires a check-in with an OV chip card. You must have enough balance on your card (€ 10 or € 20) to enter the station. If you don't have an OV chip card, please send a message to Saskia ([masked]) from the NS with your name and e-mail address, they will arrange something for you!
