/render-typst

Primary LanguageRust

SVG/PDF render some typst text, only got it working with vite, and kind of with webpack.

Usage

import init, { addFont, setSource, renderSvgMerged } from '@djakish/render-typst'
import lin_font_r from '../assets/fonts/LinLibertine_R.ttf'

// Load a font
await addFont(lin_font_r)

// Set source to the wasm 
setSource(`#text("Hello world!",fill: red)`);

// Get rendered SVG
let doc = renderSvgMerged()

Vite dependencies for wasm

With vite you would need vite-plugin-wasm and vite-plugin-top-level-await.

Setting up wtih webpack

Next config that I got to work.

const nextConfig = {
  reactStrictMode: true,
  webpack: (config, { buildId, dev, isServer, defaultLoaders, webpack }) => {
    // For wasm
    config.externals.experiments = {
      asyncWebAssembly: true,
      importAsync: true,
      layers: true,
    }

    config.experiments = {
      asyncWebAssembly: true,
      layers: true,
    }

    config.module?.rules?.push({
      test: /\.bin$/i,
      type: 'asset/resource',
      generator: {
        filename: 'assets/[hash][ext][query]',
      },
    });
    return config
  }
}

Component that worked

<button onClick={async (e) => {
    const typst = (await import("@djakish/render-typst"));
    await typst.addFont("/LinLibertine_R.ttf")
    typst.setSource(`#text("Hello world!",fill: red)`);
    let doc = typst.renderSvgMerged()
    let preview = document.querySelector<HTMLDivElement('#preview')!;
    preview.innerHTML = doc
    }}>Render</button>
 <div id='preview'></div>

Building

You need wasm-pack and rust, and dependecies for them.

wasm-pack build --target bundler
