Note that this is using the IndexedDB Promised library, not the IndexedDB
API
(see
https://developers.google.com/web/ilt/pwa/working-with-indexeddb#comparison_of_indexeddb_api_and_indexeddb_promised_library)
Fwiw, I'd rather
use https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API as a
reference.

That would be something like:
openDBRequest.onupgradeneeded = new OnupgradeneededFn() {
@Override
public Object onInvoke(IDBVersionChangeEvent event) {
doUpgrade();
return Js.undefined(); // that value will likely be ignored anyway
}
};
or, using a lambda:
openDBRequest.onupgradeneeded = event -> {
doUpgrade();
return Js.undefined();
};

Re: elemental2 indexeddb example?
Thanks, I did make some progress. I dug around a little in the javadoc
and found the IndexedDbGlobal, which I was able to use to create a new
database.
elemental2.indexeddb.IDBFactory indexedDB =
elemental2.indexeddb.IndexedDbGlobal.indexedDB;
elemental2.indexeddb.IDBOpenDBRequest openDBRequest = indexedDB.open(
"mydbtest", 1.0);
So far so good.
With a open database call, I get a returned object of
elemental2.indexeddb.IDBOpenDBRequest
(https://static.javadoc.io/com.google.elemental2/elemental2-indexeddb/1.0.0-RC1/elemental2/indexeddb/IDBOpenDBRequest.html)
In the google documentation that I have found that describes the indexedDB
open
operation,
https://developers.google.com/web/ilt/pwa/working-with-indexeddb#opening_a_database
They provide the following code:
var dbPromise = idb.open('test-db2', 1, function(upgradeDb) {
console.log('making a new object store');
if (!upgradeDb.objectStoreNames.contains('firstOS')) {
upgradeDb.createObjectStore('firstOS');
}
});
I want to register a function to execute when the database is upgraded. I
see there is a openDBRequest.onupgradeneeded(), but I just can't the syntax
right.
elemental2.indexeddb.IDBFactory indexedDB =
elemental2.indexeddb.IndexedDbGlobal.indexedDB;
elemental2.indexeddb.IDBOpenDBRequest openDBRequest = indexedDB.open(
"mydbtest", 1.0);
//how to i call a function for upgrade? I want to create some object
stores.
openDBRequest. onupgradeneeded = doUpgrade();
Thanks for your help.

Elemental2 API map directly to the native browser APIs, so you'll start with IndexedDBGlobal.indexedDB and walk your way almost exactly like you'd do in JS.

JSNI Return Results from IndexedDB Get() call?
I'm trying to get a Java object back from an IndexedDB get() call via
a JSNI method. I can't figure it out, code is below, any help is
appreciated.
I think because this code is RPC in nature, i.e. it does a call and
you wait for the success or error to come back that maybe has
something to do with it?
How do I get a useful java object back from this method? Thanks!
public native static void getItems() /*-{
var request = mozIndexedDB.open(MyDB);
request.onerror = function(event) {
