Lattice

Getting started

Lattice runs on Node.js. npm install pulls in the Mermaid CLI and Puppeteer (which downloads a matching Chromium); it does not pull Marp — the owned engine renders every first-party path. Requires Node 22+.

Install

Section titled “Install”
Terminal window
git clone https://github.com/slidewright/lattice.git
cd lattice
npm install

Render the example galleries

Section titled “Render the example galleries”

The repository ships two gallery decks as ground-truth fixtures for what the renderer produces. Render them with the bundled emulator (no network required):

Terminal window
node lattice-emulator.js examples/gallery.md examples/gallery.pdf
node lattice-emulator.js examples/gallery-mermaid.md examples/gallery-mermaid.pdf

Open examples/gallery.pdf — that is the fastest answer to “what does this produce?”.

The output extension picks the format — the same render, delivered as a vector PDF, a PowerPoint, or a PNG set:

Terminal window
node lattice-emulator.js examples/gallery.md gallery.pptx   # PowerPoint (image slides)
node lattice-emulator.js examples/gallery.md gallery.png    # → gallery.001.png, gallery.002.png, …

Render your own deck

Section titled “Render your own deck”

A deck is a Markdown file with a small front-matter block selecting a palette. Each slide is separated by ---, and a <!-- _class: ... --> comment picks the component.

---
marp: true
theme: indaco
paginate: true
---


<!-- _class: title -->


# From Signal to Strategy

of pipeline stalls trace to a single approval step.

Build it with the bundled lattice CLI (the owned engine) — the output extension picks the format:

Terminal window
node lattice-emulator.js deck.md deck.pdf     # vector PDF
node lattice-emulator.js deck.md deck.pptx    # PowerPoint (image slides)
node lattice-emulator.js deck.md deck.png     # → deck.001.png, deck.002.png, …

Need a copy someone can render with Marp? Use Export to Marp in the Drawing Board (or npm run export:marp) to produce a self-contained .zip — splits baked to literal ---, themes, assets, and a zero-install bundled renderer. Lattice itself never renders through Marp.
