Shopping List app series (useContext approach)

This project is a 'To Do list' like app created with ReactJs to implement and practice different state management approaches and the DOM testing with React Testing Library.

In this case I'm using the useContext hook to manage the state.

See the other state management approaches:

• Using hooks:
  • shopping-list-useReducer
• Using props:
  • shopping-list-props

How the App works

The Shopping list app has 2 small sections with the following features:

1. Add new item section:
   With a small form the user can write a text description for the new item and add it to the list by clicking on the 'Add item' button or by submitting the form (press Enter in the keyboad).
   To add a new item the description cannot be empty. An small validation is added for this case just for testing purpose (The button is disabled and also the add action is not executed).
2. Items List section
   The Items list has 2 counters at the end of the title where the 1st number shows the 'Crossout items' and a 2nd one shows the "Total items count". When all the items in the list are marked as "Crossout" the title shows an extra "All done" message at the end.
   If the list is empty an empty-state message will be displayed in the list.
   The user can "Crossout", "Delete" and "Restore" existing items.
   The actions will be displayed next to the item description in the list.
   When an item is marked as "Crossout" the description text styles change to be crossout and greyout. And when the item is "Restore" the styles returns to the initial state. This actions will also update the list title counters.
   The "Delete" feature will permanently removed the item from the list.

Started from a CRA template

The project was created using the Create React App (CRA) npx command template:

npx create-react-app shopping-list

NOTE: I also made some code clean-ups from the CRA template to keep it simple.
