The objectStore function opens an object store in the indexeddb database.


  • transaction:
    • A transaction or a transaction promise object
  • objectStoreName
    • The name of the object store you want to retrieve


The function returns a promise object with 2 callbacks
  • Success callback
    • The object store was retrieved successfully
    • The first argument contains transaction.
    • The second argument contains the object store
  • Error callback
    • Opening the object store failed
    • The argument object contains a custom error object.


  • NotFoundError
    • The object store with the given name wasn't found.
  • TransactionInactiveError
    • You are trying to open an object store outside or on an inactive transaction.


var dbpromise = linq2indexedDB.core.db("name", 1);
var transactionPromise = linq2indexedDB.core.transaction(dbpromise, ["objectstore"]);
linq2indexedDB.core.objectStore(transactionPromise, "objectstore").then(success, error);
function success(args){
   var transaction= args[0];
   var objectstore= args[1];
function error(args){
   var error= args;
