Micronaut Guides updated to 3!
Micronaut Guides are step by step tutorials to help you learn the Micronaut® framework.
My colleague Iván López wrote about the improvements to Micronaut Guides infrastructure back in April. We have continued to improve and automate the process.
Thanks to this focus towards automation, Micronaut Guides are updated to the latest version of the framework. Micronaut® framework 3.0.0 was released today. There are 53 guides. Many of them with up to 6 combinations (3 languages and 2 build tools). Every guide contains a ZIP file with the sample of code written with Micronaut® framework 3.0.0. Every guide contains code samples. Every code sample uses 3.0.0.
