Tl;DR

SliDevJS is so cool.

npm init slidev@latest slidev-ba-tech-talk
cd slidev-ba-tech-talk
#npm run dev -- --host 0.0.0.0 --port 4321 #http://192.168.1.11:4321/
#npm run build
#cd ./dist
#npx serve

#npx playwright install
npx slidev export --format pptx --output my-presentation.pptx
#npx slidev export --format pptx --range 1-5,8,10-12
#npx slidev export --format pdf

Remember about http://localhost:3030/overview/ or /exporter to get the .pdf

Then, its all about controlling one slides.md

The AI part was pending!

And also to make that each user will have their own bucket/folder with a .md to be edited.

Instead of a common one for all.

Conclusions

Other PPT as a Code

The most common and effective ways to create presentations “as code” (programmatically or using text-based formats) involve libraries and tools categorized by the language/format they use.

The primary categories and popular tools are:

Programming Libraries (Code-First)

These tools use native language syntax to build the presentation object by object, offering the most granular control.

Language	Tool / Library	Key Feature
Python 🐍	`python-pptx`	The industry standard for programmatically generating or modifying standard Microsoft PowerPoint (`.pptx`) files.
JavaScript/Node.js 💻	`PptxGenJS`	Excellent for creating `.pptx` files directly from web applications (browser) or server-side scripts (Node.js).
Go (Golang) 🐹	`unioffice`	A pure Go library for working with all Office Open XML documents, including `.pptx`.
Ruby ♦️	`ruby-powerpoint`	Allows manipulation and generation of PowerPoint presentations in Ruby.
Java ☕	Apache POI	A popular API used to create and maintain other file formats based on Office Open XML (OOXML) or Microsoft’s OLE2, including a component for PowerPoint (`.pptx`).

Markdown/YAML Tools (Text-First)

These tools allow you to write content in a simplified markup language (like Markdown) and then render or convert it into a presentation format. They prioritize content and speed over complex design.

Tool	Format	Output/Target
Slidev	Markdown, YAML	Generates HTML slides (often used for technical talks), offering live coding and theming.
Marp	Markdown	Generates HTML/PDF/PPTX slides from Markdown, using CSS and custom themes for styling.
reveal.js	HTML, Markdown	A robust framework for creating interactive, browser-based HTML presentations. Many tools (like Pandoc) can output to this format.
Pandoc	Markdown, LaTeX	The universal document converter. It can convert Markdown to various formats, including $\LaTeX$-based Beamer slides or even HTML for reveal.js.
Beamer	$\LaTeX$	A specialized $\LaTeX$ document class used to create high-quality, scientifically styled PDF presentations.

Web Frameworks (UI/Data-First)

While not strictly “code-as-PPT,” these modern tools use code and data to generate web-based presentations that are often exported to PDF or HTML.

Observable Plot/Vega-Lite + Static Site Generator (e.g., Gatsby, Next.js): Allows you to generate highly dynamic, data-driven slides using JavaScript/React and modern visualization code.
Quarto: An open-source scientific and technical publishing system (successor to R Markdown) that can output beautiful presentations (Reveal.js, Beamer, Powerpoint) directly from notebooks containing code and Markdown.
