React: initial project setup, structure and architecture

Starting with React is quite easy. You just need to install the npm package and can create your components. However, unlike Angular, React is not providing a whole ecosystem which comes with a architecture and everything necessary like router, module system, components, templates already prepared for immediate start. Angular is a framework, whereas React is a library for creating ui interfaces! This is a huge difference (framework vs. library). In this short article I show an example architecture which you can use, if you don’t know how to structure your app.

Based on an interesting and entertaining article on medium by Charles Scalfani. This article is a summary. If you need some explanations and examples you should read the original article.

PHP: Installation of newest package version vs. update package

There is the little bit misleading composer command: composer update. It also allow to only update 1 to n packages with composer update package1 package2 (package names as arguments.
