Hi, I might just be missing something, but what is going on when you call updateDistance() (at 5:55)? I don't see the method implemented anywhere

[travahnetshisaulu]

Thank you very much, i like the fact that is a simple task i find it hard to learn lots of information at the same time, is always the best to learn step by step

Have been trying for days to upload data to realtime database, still no success. Even after watching this video, it still doesn't work.

I'm struggling to use the onDisconnect event -- to simply remove a user from the realtime database. No documentation I can find helps with the new modular design of firebase v9. Can anyone help?

A question regarding the Firebase panel, is it possible to make a crossover of event parameters?
That is to say, if I have a parameter that is type of users and qr code associated to an event that for example is "that they have made a form"? I can make a cross between both parameters to know which user has visualized a qr inside the form?

Where is the start up code in the set up video linked to the video in the description?

[worldclasscode]

Please add source code to download, and a PDF with installation instructions :) It's always good with a CRUD source code with Create, Read, Update, and Delete :)

awesome tutorial. now i wish so hard google would make a similar wrapper for postgres. im a DBA and still like keeping logic server side with stored procs & triggers. giving system users table access still gives me shivers.

I did everything watching your videos and reading the documentation and even copying and pasting the scripts but unfortunately couldn't write a single word to my RT Database. I even tried both (npm and CDN) methods. Where can be the problem? Do I need to format my PC?

[plainpablo]

is there anyone getting this error Uncaught SyntaxError: Cannot use import statement outside a module (at firebase.js:2:1)

This video tutorial is great and helped me a lot with learning firebase.

[CNamgyel_]

I need a little help please. My firebase is kind of different from the video. Almost all UIs look different.
