Why

PowerPoint libraries are heavyweight enterprise footprints or unlicensed XML hackery. Agents building presentations in Node—from agentic docs to batch reporting—hit a brick wall: write raw OOXML files or vendor lock-in. @particle-academy/dark-slide fills that gap with a zero-dependency, isomorphic (browser + Node) PPTX writer & reader that speaks the exact deck schema agents already emit from fancy-slides, making server-side presentation generation as terse and schema-native as client-side editing.

What

A single Agent facade exposing validation, repair, serialization, and round-trip I/O: Agent.validate(deck) returns structured errors, Agent.validateAndRepair(deck) heuristically fixes common issues, Agent.toBytes(deck) produces PPTX bytes (universal), and Agent.write(deck, path) persists to disk (Node only). The deck schema is JSON-friendly objects with numeric coordinates (0..1 fractions) and inline markdown text; it perfectly mirrors fancy-slides so a DeckEditor export needs zero translation. Export surface also includes Agent.describe(deck) for plain-text summaries and Agent.jsonSchema() for LLM tool registration.

How

npm install @particle-academy/dark-slide. Import the facade and call it: import { Agent } from '@particle-academy/dark-slide'; const bytes = Agent.toBytes(deck); or await Agent.write(deck, 'out.pptx') in Node. Validate before writing: Agent.validate(deck) returns an array of typed errors with paths & hints. For broken input, try Agent.validateAndRepair(deck) first.

API surface

This package renders no UI surface — it is the hooks / APIs / server-side tooling described above.

Renders no UI. A supporting package with no rendered components, so there are no live demos — reach for the README + Changelog for the full reference, and the Issues link to file feedback.

@particle-academy/dark-slide

Zero-dependency, isomorphic (browser + Node) .pptx writer + reader for agentic deck creation. The Node/TypeScript mirror of the PHP particle-academy/dark-slide — same deck schema in, same .pptx out (feature-parity with PHP 0.5.2; the PHP package has since shipped 0.6 and 0.7, whose additions are not yet mirrored here).

The deck schema is identical to @particle-academy/fancy-slides, so a fancy-slides DeckEditor deck exports to PowerPoint with no translation — in the browser or in Node.

import { Agent } from "@particle-academy/dark-slide";

const deck = {
  id: "d1",
  title: "Quarterly Review",
  theme: { name: "default" },
  slides: [
    {
      id: "s1",
      layout: "title",
      elements: [
        { id: "t1", type: "text", x: 0.1, y: 0.4, w: 0.8, h: 0.2, content: "# Q3 Results" },
      ],
    },
  ],
};

const bytes: Uint8Array = Agent.toBytes(deck); // universal
await Agent.write(deck, "deck.pptx"); // Node only

API

Agent (static) mirrors the PHP surface:

validate(deck) → structured errors {path, expected, got, value, hint}[]
validateAndRepair(deck) → {ok, schema, errors}
toBytes(deck, opts?) → Uint8Array (universal)
write(deck, path, opts?) → {path, bytes, slides} (Node only)
read(bytes) / fromBytes(bytes) → deck schema (universal)
describe(deck) → plain-text summary
jsonSchema() → JSON Schema for LLM tool-use

Coordinates are 0..1 fractions of the slide; text supports inline markdown (**bold**, *italic*, `code`, #/##/### headings, [label](url)).
