How to export HTML in nodejs while excluding huge files

[linonetwo]

I found when using nodejs wiki, exporting HTML using this button will download a 15M HTML, which is what I need

But exporting HTML in the nodejs server-side will result in 250M+ HTML containing large PDF that I drag&drop to it.

https://github.com/tiddly-gittly/tw-mobile-sync/blob/33f8318f5e264c86c56d1a8186d104556fdb6a4e/src/server/server-get-html-endpoint.ts#L13-L20

How can I export HTML while excluding those large files? Only via modifying the export template?

Additional Context

I want to export HTML and send it to the mobile client, because I need document.write(fullHtml); to load plugins from the server.

The filter I used for normal tiddler sync

`[all[]] :filter[get[modified]compare:date:gt[${lastSync ?? ''}]]`

won't work for plugin that is older than the time lastSync.

I have a clue, which template does

browsers now limit the size of data URIs which breaks large embedded PDFs
#6189 (comment)

use? I can use that template to save HTML, to get a HTML that is the same size as the one on the browser.

I'm using root-tiddler=$:/core/save/lazy-images to start the nodejs server, but I can see some image when open the downloaded snapshot, so this might not the template when serving. And I don't know how does it exclude the pdf...

Hi @linonetwo I think you'll have to define a custom export filter that excludes the PDF files, if that makes sense?

[linonetwo]

That is OK, but I just want to reuse some existing filters or templates if there are...

What does "browsers now limit the size of data URIs" use?

[linonetwo]

I see, its core/modules/server/routes/get-index.js

Just use lazy-image template, it will filter out PDFs.

The server side rendering code is very simple, just core/modules/server/routes/get-index.js

exports.handler = function(request,response,state) {
	var text = state.wiki.renderTiddler(state.server.get("root-render-type"),state.server.get("root-tiddler")),
		responseHeaders = {
		"Content-Type": state.server.get("root-serve-type")
	};
	state.sendResponse(200,responseHeaders,text);
};
