Retrieve ALL children of specific category via API?

[btc]

Is there a way to retrieve the full list of subcategories for a specific category via the v3 read API?

I see there is a "children" object when fetching a category, but it only includes the first 10 children.

There seem to be some pagination options:

"subCategoriesLeft": 1107,
"hasMoreSubCategories": true,
"nextSubCategoryStart": 10,

But no way of passing these parameters in the API call.

This is one of the socket.io methods that is not available in the v3 read API yet. If you want to load all the subcategories you can do it with a socket.io emit. See below function

async function getSubCategories(cid) {
	// store current loaded children
	let subCats = ajaxify.data.children.slice();
	let newCats = [];
	// start from the nextSubCategory index
	let start = ajaxify.data.nextSubCategoryStart;
	do {
		// load the next page
		newCats = await  socket.emit('categories.loadMoreSubCategories', {
			cid: cid,
			start: start,
		});
		// move start to next page
		start += ajaxify.data.subCategoriesPerPage;
		// add the newly loaded children to our sub categories
		subCats = subCats.concat(newCats);
		// we are done if no new categories were loaded
	} while (!newCats.length);
	return subCats;
}

You can call this function on a category page and it would return all the subcategories of that category.
