Hey there,

I’ve been playing around with web components lately, and It's evident that Shadow DOM is an important aspect of web components, and this article aims to explain all there is to the Shadow DOM, so let’s get to it.👇🏻

Docker React

We will be setting up a dockerized react app that will provide us with a consistent environment from development (with hot reloading enabled) to production.

System Requirements (I assume you are fairly familiar with these technologies):

  1. Node V8+
  2. Docker

First we are going to create our react app, using this command:

npx create-react-app dockerized-react-app

Note: if you are using docker-machine on windows your project need to be under C:/Users/user/…

Let’s Setup the Dev Environment:

Now Let’s setup the development docker container for our react-app. Create the following files at the root of your project.

create DockerFile

create docker-compose.yml

create dev.yml

create .dockerignore
