Maximum call stack, presumably due to my 3100 line long markdown file

[boehs]

Don't ask why.

It's a glorious 138kb file

Tests I did:

1. Moving the mostrosity of a markdown file to the routes folder

• this did not work

2. Converting it to HTML before hand and putting it in my routes

• this did work.

This makes it likely a MDsveX issue

I think I know what this is but I don't know how much I can do about it. The files needs to be loaded into memory and the AST needs to exist in memory as well because this mdsvex is primarily a preprocessor. It is probably the size of the AST that is causing an issue.

I'll take a closer look and try to figure out exactly what the problem is, increasing the memory of the node process will probably fix this as a quick workaround.

Do you think you could run that markdown file through a Lorem Ipsum converter like https://loremizr.monkeymatt.com/ (to remove any actual content in the file that you wouldn't want to share publicly) and then share the loremized file? Having access to that file's Markdown structure could be quite useful for testing.

[boehs]

out of curiosity have you tried to reproduce with a generic lorum file with a massive amount of content?

I ran into the same issue. If you patch the svelte compiler, it might resolve it for you. See sveltejs/svelte#4694 for more information.

[benmccann]

The issue is hopefully fixed now with the release of Svelte 3.46.4. Could you try again and check if it works now?

@kdheepak @boehs Is this issue resolved with the current version of svelte?

[kdheepak]

Yes, for me it has!
