LGTM assuming CI agrees
I think this one and the analytics ones are where all the infra work you did in the first couple start to make it go quickly 🤞

[efstathiosntonas]

Hi @mikehardy, hope you're doing well.

After this deprecation notice there's a huge pollution in the logs :/

look how small is the scrollbar on the right 😅

don't tell me to move to v9 lol!

[mikehardy]

@efstathiosntonas I will go farther: I will insist you move to v9. There is literally no alternative, the future is no longer the future, the future is right now. The transition is actually easy though - I feared it personally in my projects and in the end was painless.

[efstathiosntonas]

@mikehardy I knew it haha!

do you have any mini guide on how to transition?

will I need initializeApp? Tried earlier to do so, thought it would pick from google services json or plist but nope 😓

[mikehardy]

@efstathiosntonas you only need to do initializeApp if you are using the "other" platform support (react-native-macos or web) which you are likely not doing - or if you are initializing secondary / non-[DEFAULT] apps, at which point you were already doing it and wouldn't have had a problem. We still handle initialization.

All the other stuff you need to change though - it's basically just each time you used to do this:

• get handle to main object for service (e.g. const auth = firebase.auth())
• call method on that main object (e.g. auth.doThing(param1, param2)

Now you do

• get handle to main object for service (e.g. const auth = getAuth(getApp()))
• call method using that main object (e.g. doThing(auth, param1, param2))

That's it.

[efstathiosntonas]

great, thanks Mike, will try it now.

[mikehardy]

best part is it is incremental at least - you can nail your hottest offenders right now to get your logs mostly clean, then do full sweep later with time available

[efstathiosntonas]

any idea why?

[russellwheatley]

@efstathiosntonas - I know why. If you want to open a new issue, I'll get that fixed 👍
