astro-typst

An Astro Integration that lets you render Typst within Astro based on typst.ts. We have made you an Astro-ish wrapper that you cannot refuse!

Features

• [x] Import packages in Typst Universe
• [x] import / include / read files or resources
• [x] Use system fonts
• [x] Selectable, clickable text layer
• [x] Set scale
• [x] Static SVGs without JavaScript
• [x] Static HTML output without JavaScript
• [x] Content collections
• [x] Write frontmatter directly in .typ
• [x] Jump between internal links (client JS needed)
• [x] Pass JS data to typst using the component (how)
• [ ] Pass data from typst to JS
• [x] Render to <img> with src= emitted SVG assets (#20)
• [ ] Responsive SVGs
• [ ] Paged output
• [x] Add font files or blobs (fontArgs in config)

Installation

npm install astro-typst
# or
pnpm add astro-typst
# or
yarn add astro-typst

The latest stable version (0.12) needs the following beta versions of typst.ts:

    "@myriaddreamin/typst-ts-node-compiler": ">=0.6.1-rc2",
    "@myriaddreamin/typst-ts-renderer": ">=0.6.1-rc2",
    "@myriaddreamin/typst.ts": ">=0.6.1-rc2",

Usage

Checkout the live demo!

As an integration

// astro.config.mjs
import { typst } from 'astro-typst';

... // other imports

export default defineConfig({
  integrations: [
    /** other integrations */...,
    typst({
      options: {
        remPx: 14,
      },
      target: (id: string) => {
        console.debug(`Detecting ${id}`);
        if (id.endsWith('.html.typ') || id.includes('/html/'))
          return "html";
        return "svg";
      },
      // === <img src="xxx.svg"> instead of inlined <svg> ===
      // emitSvg: true,
      // emitSvgDir: ".astro/typst"
      // === Add non-system fonts here ===
      // fontArgs: [
      //   { fontPaths: ['/system/fonts', '/user/fonts'] },
      //   { fontBlobs: [customFontBuffer] }
      // ],
    }),
  ],
});

The target function determines which mode a file will render in. The default is:

*.html.typ => html export
 *.svg.typ =>  svg export
**/html/** => html export
 **/svg/** =>  svg export

Then you can use .typ files just like anything else in Astro: render directly by router, or import in another file.

Example:

import Paper from "./_test.typ";

<Paper />

Force HTML output:

import Paper from "./_test.typ?html";

<Paper />

Force SVG output:

import Paper from "./_test.typ?svg";

<Paper />

You can also emit SVG to standalone files on build mode. Modify the emitSvg and emitSvgDir option in the config. (Added in v0.10)

As a component

To use the component, you need to manually install a dependency to avoid SSR errors:

npm install @myriaddreamin/typst-ts-node-compiler
# or
pnpm add @myriaddreamin/typst-ts-node-compiler
# or
yarn add @myriaddreamin/typst-ts-node-compiler

and add this to your /astro.config.(t|j)s/:

export default defineConfig({
  ...,
  vite: {
    ssr: {
-      external: [...],
+      external: [..., "@myriaddreamin/typst-ts-node-compiler"],
    },
    ...,
  },
  ...,
});

Then, you can pass either one of code | src | input to the component:

---
import { Typst } from "astro-typst/src/components";
const code = `
#set page(margin: 1em)
#let typst  = {
  text(font: "Linux Libertine", weight: "semibold", fill: eastern)[typst]
}
#show "Typst": typst

== Typst: Compose paper faster

$ cases(
dot(x) = A x + B u = mat(delim: "[", 0, 0, dots.h.c, 0, - a_n; 1, 0, dots.h.c, 0, - a_(n - 1); 0, 1, dots.h.c, 0, - a_(n - 2); dots.v, dots.v, dots.down, dots.v, dots.v; 0, 0, dots.h.c, 1, - a_1) x + mat(delim: "[", b_n; b_(n - 1); b_(n - 2); dots.v; b_1) u,

y = C x = mat(delim: "[", 0, 0, dots.h.c, 1) x
) $

#set text(font: ("Garamond", "Noto Serif CJK SC"))

#import "@preview/tablem:0.1.0": tablem

#tablem[
  | *English* | *German* | *Chinese* | *Japanese* |
  | --------- | -------- | --------- | ---------- |
  | Cat       | Katze    | 猫        | 猫         |
  | Fish      | Fisch    | 鱼        | 魚         |
]
`;

<Typst code={code} />

<!-- or HTML output: -->

<Typst code={code} target="html" />

In content collections

See demo.

Frontmatter

metadata exposes a value to the query system without producing visible content.

Attach a label frontmatter to the metadata declaration:

#let desc = [$oo$ fun with `math`]
#metadata(
  (
    title: "Test page",
    author: "Neko",
    desc: desc,
    date:  datetime(
      year: 2024,
      month: 8,
      day: 7,
    ),
  )
)<frontmatter>

yields

{
  "title": "Test page",
  "author": "Neko",
  "desc": {
    "children": [
      {
        "block": false,
        "body": {
          "func": "text",
          "text": "∞"
        },
        "func": "equation"
      },
      { "func": "space" },
      { "func": "text", "text": "fun with" },
      { "func": "space" },
      {
        "block": false,
        "func": "raw",
        "text": "math"
      }
    ],
    "func": "sequence"
  },
  "date": "datetime(year: 2024, month: 8, day: 7)"
}

This is only a demo for how various typst types will be converted; you don't need to use all of them.
