pptx-custom

Utilities to customize PPTX JSON templates in two stages:

• applyCustomContent: replace default slide content from backend JSON text.
• applyCustomTheme: apply user theme settings (palette/font/background).
• parseCustomContent: parse custom content to slide data

Install

npm i pptx-custom

Usage

import {
  applyCustomContent,
  applyCustomTheme,
  parseCustomContent,
} from 'pptx-custom'

const deckWithContent = applyCustomContent(templateDeck, backendText)

const deckWithTheme = applyCustomTheme(deckWithContent, {
  themeColors: ['#111111', '#333333', '#555555', '#777777', '#999999', '#BBBBBB'],
  fontColor: '#222222',
  backgroundColor: '#FFFFFF'
})

const slides = parseCustomContent(backendText)
const deckFromSlides = applyCustomContentToTemplate(templateDeck, slides)

Custom Content Format

applyCustomContent and parseCustomContent accept NDJSON-style lines or JSON arrays/objects of slides:

{"type":"cover","data":{"title":"Title","text":"Subtitle"}}
{"type":"contents","data":{"items":["Part A","Part B"]}}
{"type":"transition","data":{"title":"Part A","text":"Section intro"}}
{"type":"content","data":{"title":"Topic","items":[{"title":"Point","text":"Detail"}]}}
{"type":"end"}
