The refactor made pdfDoc a plain variable so renderer.isLoaded was not reactive. Svelte only tracked currentPage and scale — but when the canvas reappeared after loading, neither changed, so the PDF stayed blank. Fix: merge the two effects into one that reads canvasEl synchronously. Svelte now tracks canvasEl as a dependency; when the canvas remounts (loading spinner → false), the effect re-fires and renders the already-loaded PDF document.

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.
