pdf.js 5.x moved the JBIG2/CCITTFax/JPEG2000 image decoders into WebAssembly. The wasm lives in node_modules and was never web-served, so those decoders failed to initialise and CCITT (G4 fax) scans painted blank in production while rendering fine in dev. Add vite-plugin-static-copy (devDependency) to copy node_modules/pdfjs-dist/wasm/* into build/client/pdfjs-wasm/, so the assets are emitted into the SvelteKit client build and survive the production Docker image — not just `npm run dev`. Verified that `node build` serves /pdfjs-wasm/jbig2.wasm with 200 + application/wasm. Refs #708 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
sv
Everything you need to build a Svelte project, powered by sv.
Creating a project
If you're seeing this, you've probably already done this step. Congrats!
# create a new project in the current directory
npx sv create
# create a new project in my-app
npx sv create my-app
Developing
Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
Building
To create a production version of your app:
npm run build
You can preview the production build with npm run preview.
To deploy your app, you may need to install an adapter for your target environment.
