Get started

Prerequisites

This project uses nvm.

You need to have it installed on your machine.

Install

To clone the project on your machine, install the required dependencies and run the server, follow these commands:

$ git clone https://github.com/springload/react-redux-exercise.git

$ cd react-redux-exercise

# Install the correct version of Node/NPM with nvm
$ nvm install

# Then, install all project dependencies.
$ npm install

# Then run the server
$ npm run start

# Open your browser to http://localhost:3000

And if you want some eslint love (and you should):

npm run lint . (or specify the path to the file you want to check)

Debugging

I highly recommend that you install the Redux extension for Chrome

It looks like this:

And it will help you a lot to debug and understand what's going with your code.

with words

Don't be afraid by these images if you find them complicated. Redux just needs to be tested and you will pick it up.

Basically, a Redux cycle works like this:

A user clicks on a button on the UI (for instance)
This button dispatches an action
This action will be managed by a reducer which is listening for one or many actions
This reducer will update the store state
The new store is then passed to the component which rerenders with the new value
