Corespeed PPTX — PowerPoint Generation with JSX

Generate professional .pptx files using TypeScript JSX via @pixel/pptx.

Workflow

1. Write a .tsx file that exports a deck variable
2. Run the generator to produce the .pptx

Usage

deno run --allow-read --allow-write --config {baseDir}/scripts/deno.json {baseDir}/scripts/generate.ts slides.tsx output.pptx [--json]

• First arg: path to your .tsx slide file (must export const deck = ...)
• Second arg: output .pptx filename
• --json — structured JSON output for agent consumption

Writing Slides

Create a .tsx file. It must export a deck variable:

/** @jsxImportSource @pixel/pptx */
import { Align, clr, Presentation, Slide, Text, u } from "@pixel/pptx";

export const deck = (
  \x3CPresentation title="My Deck">
    \x3CSlide background={{ kind: "solid", color: clr.hex("F7F4EE") }}>
      \x3CAlign x="center" y="center" w={u.in(8)} h={u.in(1.5)}>
        \x3CText.P style={{ fontSize: u.font(32), bold: true }}>
          Hello, World!
        \x3C/Text.P>
      \x3C/Align>
    \x3C/Slide>
  \x3C/Presentation>
);

Units & Colors

import { u, clr } from "@pixel/pptx";

u.in(1)       // inches
u.cm(2.5)     // centimeters
u.pt(12)      // points
u.pct(50)     // percentage
u.font(24)    // font size (hundredths of a point)

clr.hex("1F4E79")  // hex color (no #)

Styling

Style props are plain objects. Use style on any component:

const style = {
  fill: { kind: "solid", color: clr.hex("1F4E79") },
  fontSize: u.font(24),
  fontColor: clr.hex("FFFFFF"),
  bold: true,
  italic: false,
  align: "center",
  verticalAlign: "middle",
  padding: u.in(0.2),
  shadow: {
    color: clr.hex("000000"),
    blur: u.emu(12000),
    distance: u.emu(4000),
    angle: 50,
    alpha: u.pct(18),
  },
  bullet: { kind: "char", char: "•" },
};

Backgrounds support solid, linear-gradient, and image.

Example: Multi-Slide Deck

/** @jsxImportSource @pixel/pptx */
import {
  Align, Chart, clr, Column, Presentation, Row, Shape, Slide,
  Stack, Table, Text, u, type Style,
} from "@pixel/pptx";

const title: Style = {
  fill: { kind: "solid", color: clr.hex("1F4E79") },
  fontSize: u.font(28), fontColor: clr.hex("FFFFFF"), bold: true,
  verticalAlign: "middle", padding: u.in(0.2),
};

export const deck = (
  \x3CPresentation title="Q2 Report" layout={{ rowGap: u.in(0.3), columnGap: u.in(0.3) }}>
    \x3CSlide background={{ kind: "solid", color: clr.hex("F7F4EE") }}>
      \x3CColumn>
        \x3CShape preset="roundRect" h={u.in(1.2)} style={title}>
          \x3CText.P>Q2 Report\x3C/Text.P>
        \x3C/Shape>
        \x3CRow>
          \x3CStack grow={1}>
            \x3CShape preset="roundRect" style={{ fill: { kind: "solid", color: clr.hex("FFFFFF") } }} />
            \x3CAlign x="center" y="center" w={u.in(4)} h={u.in(3)}>
              \x3CChart.Bar
                data={[
                  { q: "Q1", rev: 8 }, { q: "Q2", rev: 12 },
                  { q: "Q3", rev: 10 }, { q: "Q4", rev: 15 },
                ]}
                category="q"
                series={[{ name: "Revenue", value: "rev", color: clr.hex("2678B4") }]}
                labels
              />
            \x3C/Align>
          \x3C/Stack>
          \x3CTable cols={[u.in(1.5), u.in(1)]} grow={1}>
            \x3CTable.Row height={u.in(0.4)}>
              \x3CTable.Cell style={{ bold: true }}>Metric\x3C/Table.Cell>
              \x3CTable.Cell style={{ bold: true }}>Value\x3C/Table.Cell>
            \x3C/Table.Row>
            \x3CTable.Row height={u.in(0.4)}>
              \x3CTable.Cell>Revenue\x3C/Table.Cell>
              \x3CTable.Cell>$1.2M\x3C/Table.Cell>
            \x3C/Table.Row>
          \x3C/Table>
        \x3C/Row>
      \x3C/Column>
    \x3C/Slide>
  \x3C/Presentation>
);

Notes

• No manual setup required. Deno auto-downloads @pixel/pptx from JSR on first run.
• The .tsx file must export const deck = ... (the JSX Presentation element).
• Use --json for structured output: {"ok": true, "file": "...", "size": 1234}
• Output opens in PowerPoint, Google Slides, LibreOffice Impress, and Keynote.
• Use timestamps in filenames: yyyy-mm-dd-hh-mm-ss-name.pptx.
