Description

This package offers a concise introduction to Node.js (using JupyterLab), focusing only on the essential concepts and skills. It covers the fundamental topics necessary for understanding and practicing (or reviewing) Node.js, including:

• Introduction
• JSON Handling
• Working with Arrays
• Working with Maps
• Working with Sets
• Function and Lambda
• Files Operations
• Async-await, Promise and Event
• Simple HTTP server + helper client
• MongoDB
• Mongoose
• RESTful API using Express + helper client

Who should use this?

This project is designed for intermediate-level developers who are looking to deepen their understanding of core concepts in Node.js and JS. It is particularly beneficial for those who want to expand their knowledge, review general principles, or gain a broader perspective on Node.js and JS. If you are an expert in this field, you might find the material NOT directly applicable to advanced scenarios. However, if you are eager to refresh your foundational skills or explore different approaches, this resource may still offer valuable insights.

Active Development

Please note that this package is still being modified and updated. We are continuously working to improve and expand the content based on feedback and new developments in Node.js. New features, topics, and enhancements will be added over time. To ensure you have the latest dependencies and updates, you might need to run npm install periodically.
