Why does it not have 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 v10.16.3 or above
• For the fourth exercise only
  • MongoDB v4.2.3 or above
  • Robo 3T to visualize data
  • Postman to test endopints

Setup

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

git clone https://github.com/NicolasOmar/node-practice.git
cd node-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
Notes	npm run setup-notes
Weather console	npm run setup-weather-console
Weather web	npm run setup-weather-web
Task manager	npm run setup-task-manager
Chat	npm run setup-chat

How to run it

To use any app, you just have to enter its folder and run any of the scripts listed in its 'package.json' file. Each command runs with the following structure:

npm run <command-name>

In case you want to run all available commands on a row, execute the following command:

npm start
