It's not possible to delete IndexedDB database (as opposed to stores and indexes) programmatically.

As for manual workarounds, <a href="http://blogs.realdolmen.com/experts/2011/11/03/indexed-db-deleting-your-database/" rel="nofollow">this post</a> details the location of the database on Windows systems for Firefox and Chrome. 

Update: Thanks to developer Joshua Bell, Chrome implements an off-spec (but insanely useful) <code>deleteDatabase</code> method on the <code>window.indexedDB</code> object. Here's the <a href="https://bugs.webkit.org/show_bug.cgi?id=90310" rel="nofollow">crbug</a> that landed this patch. Moreover, in newer versions of IE, you can delete databases <a href="https://blogs.msdn.com/b/ie/archive/2012/03/21/indexeddb-updates-for-ie10-and-metro-style-apps.aspx?Redirected=true" rel="nofollow">via a settings panel</a>.

This is maybe overkill for your specific question, but I kept ending up here in my struggle to delete my idb.

My solution in the end was based on <a href="https://developer.mozilla.org/en-US/docs/Web/API/IDBFactory/deleteDatabase" rel="nofollow noreferrer">mozilla's documentation</a>, but required that I first close the database.

For me, in Javascript, the code looked like this:

<pre><code>my_db_instance.close(function(e){console.log(e)});
var DBDeleteRequest = indexedDB.deleteDatabase("my_db_name");

// When i had the base open, the closure was blocked, so i left this here
DBDeleteRequest.onblocked = function(event) {
 console.log("Blocked");
};

DBDeleteRequest.onerror = function(event) {
 console.log("Error deleting database.");
 console.log(event);
};

DBDeleteRequest.onsuccess = function(event) {
 console.log("Database deleted successfully");
};
</code></pre>

I needed to get rid of an indexedDB in Chrome. So I search for this lousy thing called "email assistant" on my computer using MasterSeeker. Found the thing in a bunch folders that were indexedDB in Chrome. It seemed too easy that I just delete those files. I looked up how, and ended up here. I went to chrome settings with my Windows 10 PC. I just gave it a shot at trying to clear the browsing data. Presto - all those files disappeared from indexedDB, including that dreaded "email assistant" crapola. Now when I look in the indexedDB folder all I see that has reappeared is https_mail.google.com_0.indexeddb.leveldb - which looks like a safe non-irritating thing.

I'm working in a project which involves using IndexedDB. 
As I'm begining to know this technology, I need to be able to delete an indexedDB by hand so I can start over.

I found the way to do it in Firefox, but I can't find the way for Google Chrome.

I tried deleting the content of this folder (I'm using Mac):

<code>{home}/Library/Application Support/Google/Chrome/Default/IndexedDB</code>

but it seems Chrome stil have the DB anywhere so I can't start over.
