how to identifying a deleted bookmark

In my extension, I have a listener on the chrome.bookmarks.onRemoved event.

When my listener is called, it's passed a parent and an index, rather than an image of the deleted bookmark. What I can't figure out is how do I find out which bookmark was deleted?

Happy news.

chrome.bookmarks.onRemoved callback has 'node' param. it includes the details of removed bookmark node.

You can use it from Chrome canary Version 48.0.2529.0.

You can't use the chrome.bookmarks.get API to get the removed bookmark, since it's been removed. The only solution I can think of is to keep a copy of the full bookmark tree, and to search the id of the removed bookmark. A naive implementation would be:

var bookmarks = [];

function updateBookmarks()
{
    chrome.bookmarks.getTree(function(results) { bookmarks = results; });
}
updateBookmarks();

chrome.bookmarks.onRemoved.addListener(function(id, removeInfo)
{
    console.log("Removed bookmark");
    console.log(findBookmarkWithId(bookmarks, id));

    updateBookmarks();
});

function findBookmarkWithId(bookmarks, id)
{
    if (bookmarks === null || typeof bookmarks === "undefined")
        return null;

    for (var i = 0; i < bookmarks.length; i++) 
    {
        if (bookmarks[i].id === id)
            return bookmarks[i];

        var child = findBookmarkWithId(bookmarks[i].children, id)
        if (child !== null)
            return child;
    }

    return null;
}

// keep local copy up to date 
chrome.bookmarks.onCreated.addListener(function(id, bookmark)
{
    updateBookmarks();
});

chrome.bookmarks.onChanged.addListener(function(id, bookmark)
{
    updateBookmarks();
});

// TO DO: deal with chrome.bookmarks.onImportBegan / onImportEnd
