Over the past year, I’ve noticed that some of my demos have too many steps to remember. I’ve written them down in scripts, but I’ve recently learned it’s much cooler to automate them with tools powered by Schematics! Schematics is...

i18n in Java 11, Spring Boot, and JavaScript

avatar-matt_raible.jpg Matt Raible

What are i18n and l10n? Internationalization (i18n) is the process of making your application capable of rendering its text in multiple languages. Localization (l10n) means your application has been coded in such a way that it meets language, cultural, or other requirements of a particular locale. These requirements can include formats for date, time, and currency, as well as symbols, icons, and colors, among many other things. i18n enables l10n. Why is i18n and l10n...

Build a Reactive App with Spring Boot and MongoDB

avatar-moksamedia.jpg Andrew Hughes

Reactive apps allow you to scale better if you’re dealing with lots of streaming data. They’re non-blocking and tend to be more efficient because they’re not tying up processing while waiting for stuff to happen. Reactive systems embrace asynchronous I/O. The concept behind asynchronous I/O is straightforward: alleviate inefficient resource utilization by reclaiming resources that would otherwise be idle as they waited for I/O activity. Asynchronous I/O inverts the normal design of I/O processing: the...
