Help in setting getInformationEpubItemChildNodes()

[gamebeaker]

In a few parser i had the problem that the description of the book isn't in the dom but easily accessible.
Example:
88xiaoshuo.net
URL of dom: https://m.88xiaoshuo.net/Partlist/98781/
URL of info: https://m.88xiaoshuo.net/book/98781/
genesistudio.com
In the api request to get all Chapter is a description for the book with author etc. in the json response.

How can i get the info for example from an api request?
I think a possible solution would be to make
getInformationEpubItemChildNodes()
extractDescription()
async
to use
let data = (await HttpClient.fetchJson(dom.baseURI + "/__data.json")).json;
and extract the description.

The downside of that is you'd need to update all existing implementations with an async. It's just a search/replace exercise, but numerous hits. Tedious, but not difficult.

The other obvious option (to me) is to create async versions of the two functions. And only provide an implementation if required.
Which is how getInformationEpubItemChildNodes() is used. E.g.

WebToEpub/plugin/js/Parser.js

Lines 326 to 328 in 8bd1188

	if (this.userPreferences.addInformationPage.value &&
	this.getInformationEpubItemChildNodes !== undefined) {
	epubItems.push(this.makeInformationEpubItem(this.state.firstPageDom));

Less work now, but complicates things going forward. So, I agree with making them async.

Note, most implementations of getInformationEpubItemChildNodes() just get the summary, so they're duplicating extractDescription(). And, in fact, the base implementation of extractDescription is now to delegate to getInformationEpubItemChildNodes().
