Node.js OfficeGen Example to Add Text & Images in Powerpoint Presentation in Javascript

Welcome folks today in this blog post we will be using the officegen library to generate powerpoint files and adding text and images in node.js and javascript. All the full source code of the application is shown below.

Get Started

In order to get started you need to make a new node.js project using the below command as shown below

npm init -y

npm i officegen

npm i pptx

And after that you need to make a new index.js file and copy paste the following code

index.js

const officegen = require('officegen')
const fs = require('fs')
// Create a new PPTX file
let pptx = officegen('pptx')

// Add a new slide to the presentation
const slide1 = pptx.makeNewSlide();

// Add text to the slide
slide1.addText('Hello, world!');

// Create a new slide
let slide2 = pptx.makeNewSlide();
// Add Image 
slide2.addImage('image.jpg')
// Set save path
let out = fs.createWriteStream('image.pptx')
// Save
pptx.generate(out)

const officegen = require('officegen')

const fs = require('fs')

// Create a new PPTX file

let pptx = officegen('pptx')

// Add a new slide to the presentation

const slide1 = pptx.makeNewSlide();

// Add text to the slide

slide1.addText('Hello, world!');

// Create a new slide

let slide2 = pptx.makeNewSlide();

// Add Image

slide2.addImage('image.jpg')

// Set save path

let out = fs.createWriteStream('image.pptx')

// Save

pptx.generate(out)

As you can see we are importing the xlsx and officegen library at the top and then we are adding a new slide inside the powerpoint file using the makeNewSlide() method. And then we are adding the text using the addText() method and then we are adding the image using the addImage() method. And then we are generating the pptx file using the generate() method.
