Life-changing tutorial. The presentation is clear and simple. I like that it’s only one hour—perfect amount of time to explain this type of topic.

[anastariq]

Great work ! I rarely enjoy watching tutorial videos, but this one was 100% enjoyable.Especially the sound when you change screens :D .

[viacheslavromanov]

Awesome and comprehensive explanation with the nice examples!💪🏻That's what we developers really love ❤️Appreciate the effort, Todd 🙏🏻

[UsamaKarim]

Yes, Please! Keep it lengthy & comprehensive. We want to get all the knowledge in one place.

[BrianTX]

Great video. I love how you include relevant use cases for your examples.

[amer]

make it longer, and cover more stuff. please!

[daneet]

Had issues using Firebase Realtime Database until this video. I enjoyed watching it and have been able to get proper understanding of its usage which I'll proceed further by reading the documentation. I also think making a longer in depth video like this one is much better than shorter videos.

[RogiervanApeldoorn]

I really like this kind of videos. Very good explanation! Keep up the good work!

[Zizost]

Perfect tutorial! That's really a very informative one, I thought I am good with RTDB, but after watching this, I've realized that I've missed lots of good stuff!
Thanks Todd

[mohammadnazari]

This tutorial below my mind! Awesome work, Todd!!

[darokadx]

Very good video, it even answers one of my question on StackOverFlow about how to convert DataSnapshot to a Data model object !
Format is really nice, and explanations really clear, i was simply hoping you would cover the RTDB scaling / Sharding data but i guess this will be for another video 👌🏻

[prelude]

I like this new presentation format and nicely explained. Thank you.

[estranhokonsta]

Nice. Many basic but certainly good things in this video.
The addition of the optional pattern designs was cool too.

One problem of this longer videos is that there is a greater probability of them being too (dated) specific to the software versions used in it, but i still think that it brings great value to the channel. Why worry for something that hasn't come yet? Nobody would do anything that way.

The ideal would be to keep the two formats (short and long videos).
And use them according to the occasion.

You make great videos. They are really fun to watch, while being very educational.

The problem I have with Firestore is the limited querying capabilities. Compared to SQL - it's like a toy, not suitable for "real application".
Some examples:
1. No way to count records, without fetching them
2. Cant query by comparing two fields of the same doc
3. Cant query for doc which lack a field (which would be useful for maintaining a denormalized data-model)
4. No uniq costraints

And so on

Finished the video woooo. It's 2328hrs on a school night, but well worth it; the video answered a tonne of questions.

[justvikas]

I really like this, basic but covered many important things.

[komellar]

Finally some good realtime database tutorial ✊

[maxeem]

[maxmaeffert]

this might be the best guide I've ever seen
