Why it has not any updated dependencies?

After finishing its related Udemy course, I archive this repository and unarchive it when I start a new training and add a link in the Other practice repos section referring to its new repo. But I don't update any associated dependency due to technology changes during the years between each practice, and the produced code which works with the mentioned requirements.

Requirements

• Node v16.13.2 or above

Setup

After cloning the repo, go to the created folder and install the node packages.

git clone https://github.com/NicolasOmar/typescript-practice.git
cd typescript-practice
npm run setup-all

setup-all is the command to install all the projects, but if you want to do it one by one, you can change that last line for one of the following:

App Setup	Command
All	npm run setup-all
Basics	npm run setup-basics
Configs	npm run setup-configs
Classes, Interfaces & Types	npm run setup-classes
Generics & Decorators	npm run setup-generics
Practice Demo #1	npm run setup-drag-and-drop
Practice Demo #2	npm run setup-select-and-share
React & Node	npm run setup-react-and-node

How to run it

To run any specific exercise, execute the following command in the project´s folder:

npm start
