Creating from Scratch — Workflow

Step 1: Select Color Palette & Fonts

Choose a palette and font pairing matching the topic and audience.

Step 2: Plan Slide Outline

Classify every slide as exactly one type: Cover, TOC, Section Divider, Content, Summary.

Step 3: Generate Slide JS Files

Create one JS file per slide. Each exports createSlide(pres, theme).

Step 4: Compile into Final PPTX

const pptxgen = require('pptxgenjs');
const pres = new pptxgen();
pres.layout = 'LAYOUT_16x9';

const theme = {
  primary: "22223b",
  secondary: "4a4e69",
  accent: "9a8c98",
  light: "c9ada7",
  bg: "f2e9e4"
};

for (let i = 1; i <= 12; i++) {
  const num = String(i).padStart(2, '0');
  const slideModule = require(`./slide-${num}.js`);
  slideModule.createSlide(pres, theme);
}
pres.writeFile({ fileName: './output/presentation.pptx' });

Step 5: QA

Verify all slides render correctly and meet design standards.

Slide Format

// slide-01.js - Cover slide
const pptxgen = require("pptxgenjs");

function createSlide(pres, theme) {
  const slide = pres.addSlide();
  slide.background = { color: theme.bg };
  slide.addText("Presentation Title", {
    x: 0.5, y: 2, w: 9, h: 1.2,
    fontSize: 48, fontFace: "Arial",
    color: theme.primary, bold: true, align: "center"
  });
  return slide;
}
module.exports = { createSlide };

Dependencies

• pip install "markitdown[pptx]" — text extraction
• npm install -g pptxgenjs — creating from scratch

Common Pitfalls

Verification Checklist

• Color palette and fonts selected
• Slide outline planned with all page types
• Each slide module exports synchronous createSlide
• Theme object uses correct key names
• Compile script runs without errors
• Output presentation renders correctly
• Page numbers on all slides except cover
