Your first React app

Back in the days I told people I develop back-end AND front-end. Meaning next to PHP I wrote the html/css and a little bit of jquery myself and that was enough.

Now a days a see a lot of frameworks such as Vue.js, AngularJS and ReactJS. Since a back-end developer should know a little bit about front-end, I learned myself javascript so I at leas can understand. Which is totally different then writing it yourself.

Today I've came to a point I told people I actually would like to learn a front-end framework and ReactJS it is! Altough ReactJS is not really a framework (first thing I learned today), it is a library. But I've been told ReactJS is working with components and... it... is... awesome!

So to my future self and hopefully you, I though I'll give it a try and tell you how to create your very first ReactJS app.

Make sure you have installed Node 14.0.0 and NPM 5.6 or higher

$ sudo apt update
$ curl -sL https://deb.nodesource.com/setup_14.x | sudo bash $ sudo apt -y install nodejs

Create your project and install Create React App

$ npx create-react-app my-first-react-app

Go into your new project

$ cd my-first-react-app

Run it and high five yourself!

This should open a new tab in your browser to http://localhost:3000/

Thats it! Done. Easy peasy lemon squeezy
