Node.js Projects in the packages/ Folder

This folder contains multiple Node.js projects, each configured to work with both npm and yarn. The setup is organized into distinct directories, with shared configurations and dependencies under about-package-json.

📁 Directory Structure

🗂 about-package-json

The about-package-json folder contains configuration files for npm and yarn package managers, including dependencies and lock files.

• npm:

  • Uses npm as the package manager.
  • Dependencies are listed in npm/package.json.
  • Lock files are managed with npm in npm/package-lock.json.

• yarn:

  • Uses yarn as the package manager.
  • Dependencies are listed in yarn/package.json.
  • Lock files are managed with yarn in yarn/yarn.lock.

Common dependencies like node-emoji, chalk, and others are used across the configurations.

🗂 project_1

Project 1 is a simple web server application that displays the current time in various cities based on their time zones.

• Dependencies:

  • chalk: For colorizing console output.
  • luxon: For handling and formatting date and time.
  • server: A simple HTTP server library.

• Usage:

  • The server runs on port 8080. You can access different routes such as /roma, /luanda, /seoul, and /cuiaba to get the current time in those cities.

For implementation details, refer to the index.js file in the project_1 directory.

🗂 project_2

Project 2 scrapes quotes or thoughts from the internet based on an author's name and saves them to a file.

• Dependencies:

  • pensador-scrap: A library to scrape quotes.
  • fs: For file operations to store scraped quotes.

• Usage:

  • The script fetches thoughts by Alan Turing and saves them in phrases.txt.
  • You can change the author name or modify the script to fetch quotes from other authors.

For implementation details, check the index.js file in the project_2 directory.

🗂 project_3

Project 3 is a command-line interface (CLI) program to manage user data with operations like adding, editing, deleting, and viewing user information. The data is stored in bank.json.

• Dependencies:

  • terminal-kit: For interactive CLI menus.
  • uuid: For generating unique user IDs.

• Usage:

  • Users can interact with the program via a menu system to manage user data.

For full instructions and code, refer to the index.js file in the project_3 directory.
