📖 Documentation

Quick Start Guide

PptxGenJS PowerPoint presentations are created via JavaScript by following 4 basic steps:

Angular/React, ES6, TypeScript

import pptxgen from "pptxgenjs";

// 1. Create a new Presentation
let pres = new pptxgen();

// 2. Add a Slide
let slide = pres.addSlide();

// 3. Add one or more objects (Tables, Shapes, Images, Text and Media) to the Slide
let textboxText = "Hello World from PptxGenJS!";
let textboxOpts = { x: 1, y: 1, color: "363636" };
slide.addText(textboxText, textboxOpts);

// 4. Save the Presentation
pres.writeFile();

Script/Web Browser

// 1. Create a new Presentation
let pres = new PptxGenJS();

// 2. Add a Slide
let slide = pres.addSlide();

// 3. Add one or more objects (Tables, Shapes, Images, Text and Media) to the Slide
let textboxText = "Hello World from PptxGenJS!";
let textboxOpts = { x: 1, y: 1, color: "363636" };
slide.addText(textboxText, textboxOpts);

// 4. Save the Presentation
pres.writeFile();

That's really all there is to it!

✨ Add Professional Animations

Bring your presentations to life with entrance, emphasis, exit, and path animations - just like PowerPoint's built-in effects.

Basic Animation Example

let pptx = new PptxGenJS();
let slide = pptx.addSlide();

// Add text with a simple fade-in animation
slide.addText("Hello World!", {
  x: 1,
  y: 1,
  fontSize: 36,
  animation: "fadein"
});

// Add a shape with a fly-in animation from the left
slide.addShape(pptx.shapes.RECTANGLE, {
  x: 2,
  y: 3,
  w: 3,
  h: 2,
  fill: { color: "4472C4" },
  animation: {
    type: "flyin",
    direction: "left",
    duration: 1000
  }
});

pptx.writeFile();

Advanced Animation Configuration

// Image with custom animation timing
slide.addImage({
  path: "logo.png",
  x: 1,
  y: 1,
  w: 2,
  h: 2,
  animation: {
    type: "zoom",
    direction: "slideCenter",
    duration: 1500,
    delay: 500,
    trigger: "afterPrevious"
  }
});

// Table with emphasis animation
slide.addTable(tableData, {
  x: 1,
  y: 3,
  w: 8,
  animation: {
    type: "pulse",
    duration: 800
  }
});

Available Animation Types

Entrance Animations:

• appear, fadein, flyin, floatin, split, wipe, shape, wheel, randombars, zoom, growandturn, swivel, bounce

Emphasis Animations:

• pulse, colorpulse, teeter, spin, growshrink, desaturate, darken, lighten, transparency, objectcolor, complementarycolor, linecolor, fillcolor

Exit Animations:

Path Animations:

• pathdown, patharcdown, pathturnright, pathcircle, pathzigzag

Animation Options

Many animations support additional options:

// Direction options (for fly, float, split, wipe, zoom)
animation: { type: "flyin", direction: "top" | "bottom" | "left" | "right" | "topLeft" | "topRight" | "bottomLeft" | "bottomRight" }

// Shape options (for shape animations)
animation: { type: "shape", shape: "circle" | "box" | "diamond" | "plus", direction: "in" | "out" }

// Wheel spokes (for wheel animations)
animation: { type: "wheel", spokes: 1 | 2 | 3 | 4 | 8 }

// Spin options
animation: { type: "spin", direction: "clockwise" | "counterClockwise", amount: "quarterSpin" | "halfSpin" | "fullSpin" | "twoSpins" }

// Color options (for color animations)
animation: { type: "colorpulse", color: "FFFF00" }

// Transparency levels
animation: { type: "transparency", level: 25 | 50 | 75 | 100 }

Timing and Triggers

Control when animations play:

animation: {
  type: "fadein",
  duration: 1000,        // Animation duration in milliseconds
  delay: 500,            // Delay before animation starts
  trigger: "onClick"     // "onClick" | "withPrevious" | "afterPrevious"
}
