- Create a simple (ha!) React hello world app and try to understand the magic.
How do all the pieces actually fit together and function? I really don't know. Here we try to start small see if we can figure it out.
If I remove package A will the thing work?
Why is package B in there?
Is this tool just for X or does it do something else also?
It can all be rather overwhelming!!!!
Can I ever understand it? Should I try, or just use some other tool that hides it all?
There is a cool npm package called create-react-app That mostly hides it all. Works great until it doesn't. At that point, you can
eject and join me on the quest to answer the expletive WTJS (WhatThejs)
Join me on a step by step struggle to detangle the madness.
To create a default ejected version of create-react-app execute the following commands.
npm install -g create-react-app create-react-app cra cd .\cra\ npm run eject
