Svelte 5: Deprecation Warning: context="module" is deprecated, use the module attribute instead

[ThomasPais]

Description:

I am encountering deprecation warnings when using Svelte 5. The warnings indicate that context="module" is deprecated and should be replaced with the module attribute svelte 5 preview documentation.

The warnings occur when the markdown files are loaded from the JSON:
+page.server.ts

import type { Post } from '$lib/types';

export async function load({ fetch }) {
	const response = await fetch('api/blog');
	const posts: Post[] = await response.json();
	return { posts };
}

console

[vite-plugin-svelte] src/lib/blog/tenth-post.md:1:8 `context="module"` is deprecated, use the `module` attribute instead

Environment:

Svelte 5
Node.js > 20
MDsveX 0.12.3

Expected Behavior:

No deprecation warnings should appear if the correct attribute is used.

Actual Behavior:

Deprecation warnings appear for each instance of context="module".

The warning is harmless but I'll fix it before the release of 5.0.

@pngwn Svelte 5.0 is released, I know it's harmless, but it would be nice not to have console (and therefore CI) being spammed with the warning <3

Is there any update on the issue? I manually patched main.cjs.js to get rid of the console output temporarily. It seems there hasn't been any update to mdsvex in the last three month or so. Is this project still maintained?

[pngwn]

Yeah I forgot about this.

Project is still maintained but this is relatively harmless (although annoying).

You can do this to work around it in Svelte 5. See this comment.

// svelte.config.js

const config = {
    ...
  compilerOptions: {
    warningFilter: (warning) =>
      warning.code !== "script_context_deprecated",
  }
}
