Web Development meets Data Science - Data Science & Backend Workshop

Getting started with Github Codespaces or Gitpod

Description

This repository contains the materials used in the TechLabs workshop 'Data Science & Backend Workshop'. It gives an overview on how Web Development can be combined with Data Science.

Therefore the following topics are covered:

Recommended for tracks	Technologies	Note
Web Development	HTML, JavaScript, CSS, NodeJS	Web only project
Web Development & DS/AI	HTML, JavaScript, CSS, NodeJs and/or Python	Web & DS/AI project
DS/AI	Python (and minor HTML & CSS)	DS/AI project

Web Development

Technologies:

• HTML, CSS, JavaScript & NodeJS

Frontend:
The frontend can be either created in plain HTML, CSS and JavaScript or a framework like React, Angular or Svelte could be used.

Backend:
For the backend a framework like Express.js is recommended as described in the web development track.

Communication between frontend and backend:
REST API, GraphQL, WebSocket or HTTP/2

Web Development & Data Science / Artificial Intelligence

Technologies:

• HTML, CSS, JavaScript, NodeJS
• Python

Frontend: The frontend can be either created in plain HTML, CSS and JavaScript or a framework like React, Angular or Svelte could be used.
Plotly can be used for interactive charts and graphs.

Backend:
For the backend a Python based framework like FastAPI is recommended.

Communication between frontend and backend:
REST API

Data Science / Artificial Intelligence

Technologies:

• Python

Frontend:
CSS only for tuning the UI

Backend:
Use a framework like dash or streamlit

Communication between frontend and backend:
Handled automatically by the framework
