I am working on a weird kind of site where I only need to send forms to firestore and save pdf files to firestorage. Not even running any server-side code, just html and JS on the final client. My organization will only give an apache server path to run html, CSS and JS. Later I'll need to read but I'm the only user with read access so it's not a big deal because I will run that locally on my node.js CLI.

But I am looking forward to make my code as safe and efficient as possible even tho I have no idea what I'm doing 60% of the time.

Reading the docs and code online I realized that I am not doing unsubscribe() when I do my onAuthStateChanged(). By searching about memory leaks on JS I found a guy saying that if I meant to keep something live up in memory then I shouldn't unsubscribe from it. But as I said, I have no idea what I am doing.

Here is some of my .js and my login.html I am worried about 4 things, here I go:

1. should I unsubscribe() after my sign-in-out onAuthStateChanged ends? if so, where?
2. is it ok to set all this code inside window.onload ?
3. Should I split this code into modules so I can re-use the initializeApp() and other repetitive code or it is not recommendable since I am using CDN to import the firebase modules instead of using the import sentence.
4. Am I supposed to do the initializeApp() on every single one of my html pages? or doing it once on the login and forcing the user to login via vanilla JS will be the way to go?

I'm having problems with the 'edit' action of my users. I can create new users, but I cannot update them.

This is my edit method in the UserController:

I need to copy the entire row of Google Sheets if mail set in Form matches with the one stored in a data row. This is an example of my code, but the problem is that when it's "true" and the mail matches with the one on Sheets, it copies the last row and not the one with the mail matched.

Example:

I'm benninger in flutter and I need in my TextFormField a filter, if don't have at least one uppercase or lowercase letter, or a number, show error in a text in red with: "Should be have a number", for example.

This is my form (a part, with the relevant parts: textformfields and the voidinitState()):

I'm new in flutter and I'm making a register form , I need change the color of password's textfields in real time if the passwords aren't equals, I may not be looking right, but I can't find how to do it (except one with validator: but this doesn't work in TextField).

This is an example:

My code:

I'm using Retrofit to send data to a database but the body saved not is the same that I sent

I'm sending One image in base64 but when I check the file I see that is full of /n spaces

What could be happened?

the problem is with the variable called Adjunto

Codes:

Retrofit provider:

I have a database something like this:

I have been working with xcode 12 and swiftui. In my app I have textFiel with a localizable placeholder in Spanish and English, I switch to xcode 13 and it doesn't show me my localizable placeholder

this only happens in TextField, with SecureField it does not happen even with Text

this is my code
