@office-open/core

Shared OOXML infrastructure — descriptors, DrawingML, charts, SmartArt, OPC, validators, and converters.

Features

• Descriptor Runtime — CustomDescriptor<T> and ElementDescriptor<T> for bidirectional XML stringify/parse
• DrawingML — Fills, outlines, effects, geometry, text body, scene 3D, and more
• Chart Components — Shared chart types (bar, line, pie, area, scatter) and chart collection
• SmartArt Components — Data model, tree-to-model converter, layout/style/color definitions
• OPC (Open Packaging) — Content types, relationships, and ZIP packaging
• Value Validators — Runtime validation for OOXML spec types (ST_HexColor, ST_OnOff, ST_DecimalNumber, etc.)
• Unit Converters — TWIP and EMU conversions (mm/in/pt/px)
• ID Generators — Sequential numeric IDs, nanoid, SHA-1 hash, UUID v4
• Template Patching — Placeholder replacement, XML traverser, and token replacer
• OOXML Compliance — All types verified against ISO/IEC 29500-4 XSD schemas

Installation

# pnpm
pnpm add @office-open/core

# npm
npm install @office-open/core

# yarn
yarn add @office-open/core

# bun
bun add @office-open/core

Quick Start

import {
  hexColorValue,
  decimalNumber,
  convertMillimetersToTwip,
  convertPixelsToEmu,
  convertInchesToEmu,
  convertPointsToEmu,
  uniqueNumericIdCreator,
} from "@office-open/core";

// Value validators
hexColorValue("#FF0000"); // → "FF0000"
hexColorValue("auto"); // → "auto"
decimalNumber(10.7); // → 10

// Unit converters
convertMillimetersToTwip(25.4); // → 1440 (1 inch)
convertPixelsToEmu(100); // → 952500
convertInchesToEmu(1); // → 914400
convertPointsToEmu(12); // → 152400

// ID generators
const gen = uniqueNumericIdCreator();
gen(); // → 1, 2, 3, ...
