Hi, Steve! I just wanna say that I'm so thankful that I found your channel. I find many interesting videos here. Tutorials that aren't popular(I couldn't find many youtuber talk about these topics on KZfaq), but important to know (like this one). As a self-learner, your channel really helps me.

YOU ARE THE MAN!!!!!!!!! Looking all over the web and found only crappy tutorials with partical code and cryptic guidance until landing here. YOU ROCK MAN!!!! Subbing.

Clear and high level teaching. Thank you so much

what a great explanation Steve!, from Indonesia 👍👍

Thanks Steve for deep diving with us! Great theme!

HI, Steve! Maybe I'm being dense here, but can you explain why you're encapsulating your code in an IIFE? I've looked online and the best I can gather is, that it prevents global scope issues. However doesn't putting it in a const already prevent that? I'm loving the tutorial by the way. Cheers!

Hello, thank you for this amazing TUTORIAL! I've seen the Google and Microsoft video and I didn't understand it. I need to see the code to understand :D Also, if there are some entries in the existing collection and I trigger a new version, will this remove all the entries in the store? Or is the upgrade version just to trigger that function to modify the collections etc?

Thank you so very much for the series. I watched both this and service worker’s, and I cannot be more grateful. I have a question if I may: around the beginning, you did mention how to protect our indexDB with service worker, but I still failed to realize how after watching all the videos… may you please explain?

Steve, I'm curious if the upgrade event was ever meant for migrations or data initialization? For example, if a property needs to be added to a set of data in a newer version of the application and you want to backfill the property values in older data. I'm trying to gauge if I'm making bad assumptions in trying to do something like that within the upgrade event. I'm getting errors that look like "DOMException: IDBTransaction.objectStore: Transaction is already committing or done." Is that event.target.result db only meant for createObjectStore and indexing? Or maybe my issues might lie in an async quark of the wrapper I'm using (IDB)

hey steve thanks for the video, i have a question here if i already have created store with some keypath with "Id" and now i want to change the keypath as composite of "Id" & "Name" of the existing store is it possible? if yes then how?

Excellent tutorial. Looking for new team members...Interested in working on a PWA project?

What the advantages of making it with vanilla js instead of the library in the prev video

Thanks for this series, i'm going to watch it all. I'm trying to follow your example from square one and my database will not create (and according to my debug statements, that 'init' block never executes. I see that the basics of opening the database are inside a function called 'init'. Is there something 'magical' about the 'init' function or 'init' in general? I don't see that your code calls this function directly, am i right? Obviously, it's meant to initialize but as i follow along, if i can't create the database using your methods, i'm wondering how far i will get. I'm sure that the author is too busy to comment, but if anyone reading this has thoughts, i'd like to hear them. I'm learning! :-)

Hi Steve, i have a question: say i have an application with login username and password, and i am creating an store which stores the user data, so say it stores the username for every login, how do i build a store which stores all the usernames in the indexed db and checks for the username before loading the application, thanks in advance

documentation writers should be ashamed

The lip smacking is terrible. :(
