Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

pptx2json

Node.js CI npm MIT License

Operating Powerpoint file (Microsoft Office 2007 and later) as Office Open XML without external tools, just pure Javascript.
Providing two main functions:

  • Parse from a PowerPoint file to Json
  • Parse from a Json to PowerPoint

The images, movies, audio files and so on in a PowerPoint are treated as binary.
This is strongly inspired from pptx-compose.

Installation

$ npm install pptx2json

Usage

Parse a PowerPoint file to Json

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson('path/to/pptx');

Rebuild a PowerPoint from Json

If you want to get a buffer below:

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson('path/to/pptx');
:
// return buffer to pptx 
const pptx = await pptx2json.toPPTX(json);

Otherwise want to write a file below:

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson('path/to/pptx');
:
// write pptx to the path 
await pptx2json.toPPTX(json, {'file': 'path/to/output.pptx'});

Get max id, rid in slides.

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson(testPPTX);
const ids = pptx2json.getMaxSlideIds(json);
// {'id': 5, 'rid': 3}

Get slideLayoutType Hash.

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson(testPPTX);
const table = pptx2json.getSlideLayoutTypeHash(json);
// {
//    'title': 'ppt/slideLayouts/slideLayout1.xml',
//    'blank': 'ppt/slideLayouts/slideLayout7.xml'
// }
