TO start - Redux in the wild

I am going to assume you know React, JS, Typescript

Visit my portfolio website - show a smaller store Shopping cart, user info, dark mode Redux is still being used

Visit Reddit/NPR - they have a Redux store

Why use Redux?

• Global Store - everything and anything can access it, ie, a database for your frontend

• Avoid props drilling

• The tooling is AMAZINGGGGGGGGGGGGGGGGGGGGGGGG

• You are going to get asked about it in your React interviews 🙃

Warning - Redux has a ton of moving parts

It's complicated. It's okay to feel overwhelmed. Even I don't know everything.

History - mutating was awful, now we are better with Redux Toolkit

Start with CRA install

npx create-react-app my-app --template typescript

make a shopping cart

after all, a shopping cart is probably going to be needed to be 'seen' everywhere, so it's a great first case.

make two store fronts in Next.JS

As simple as possible, no stress

What goes in the Redux store?

Everything? NO.

Use context API for small needs. Even some props drilling is okay.

Devs can complain about Redux when the store gets too big - so be mindful of that.

=================================

Wth is a reducer

Reducers are functions that take the current state and an action as arguments, and return a new state result. In other words, (state, action) => newState.
