🚀 go-pugleaf

Here's what I use:

//DESCRIPTION: Makes page size same as only page item

//Works only on single-page documents with a single (top-level) page item

myDoc = app.documents[0];

if (myDoc.pages.length != 1) {
	Alert("This script works only on single-paged documents");
	exit();
}

if (myDoc.pageItems.length != 1) {
	Alert("More than one page item on page. No can do.");
	// Could offer to group them before proceeding
	exit();
}

myBounds = myDoc.pageItems[0].visibleBounds;
myDoc.pages[0].marginPreferences.bottom = 0;
myDoc.pages[0].marginPreferences.top = 0;
myDoc.pages[0].marginPreferences.left = 0;
myDoc.pages[0].marginPreferences.right = 0;

myDoc.documentPreferences.pageHeight = myBounds[2] - myBounds[0];
myDoc.documentPreferences.pageWidth = myBounds[3] - myBounds[1];

myDoc.pageItems[0].move([0,0],undefined);
