Cannot find prismjs components at runtime on Vercel #548

Open CobyPear opened 8 months ago

CobyPear commented 8 months ago

My blog is using mdsvex to dynamically compile markdown files in a load fn in SvelteKit, then returns them to the client. I have been using {@html } for this and it works fine. I recently added a codeblock and I recieved an error after publishing the post:

Error: Cannot find module 'prismjs/components/prism-bash'

Do I need to install prismjs, and if so should it be listed as a peer dependency? edit: I tried installing prismjs as a prod dependency and it still failed. I will try a CDN import in the script tag to workaround for now. edit2: oh duh that didn't work since the module isn't found in the serverless fn, not the client side.

Thanks!

Have you tried <svelte:component this={content} /> instead of interpolating {@html content} on an element?

Hi, @steven-aj. I have tried that but I get the following error which I'm not really sure where to start with:

Error: <svelte:component this={...}> is not a valid SSR component. You may need to review your build config to ensure that dependencies are compiled, rather than imported as pre-compiled modules. Otherwise you may need to fix a <svelte:component this={...}>.
