React Native Touch ID - react-native

I was using this library for touch id / face id authentication. Is there any way I can get the event when the user starts placing finger on the touch id sensor? The library seems to be good but I didn't find much that solves my problem. All I can do now is to authenticate the user and get the result ( either error or success ) on the fly.
Thank You

You can use react-native-mmkv or React Native Async Storage to save your id in memory and load it.

Website replicating in React Native, WebView vs code, notifications needed

first time asking here as i am looking for some guidance before i start coding.
I have been developing websites mostly in PHP/MySQL/Jquery for years. As I was requested to port a website to an app, I selected React Native in order not to learn 2 different languages for IOS-Android.
I subscribed to some react native lessons, as I found it very clear and fun to follow, and it indeed is.
But here I am finding that to replicate the website is a truly difficult task for me. A temporary version exists at https://app.thallo.care/app.php?language=en (view on mobile if you like). There are many fixed positioned things and floating menus that i cannot easily program on react native.
I tried webview, it works wonderfully, but i am not positive i will be able to implement notifications the way i want to, or custom app styling with inject javascript i am unsure it will work.
The only app difference comparing to the desktop version, is that the user will receive notifications. The website will have a calendar where he will add events, and i need to send notifications to the user device on the event datetime that he has set.
Now the question... Should i use webview and manage notifications on a third party app like amazon SNS or anything else, will i get per-user notifications on events with webview? (I dont need to open a specific page on the app, but it would be nice). Or should i insist on react native coding and try to replicate as much as possible, to be able to have proper notifications? Reminder - the events won't be sent by the app. they are stored in MySQL and should be stored on some other service as well (that i dont know of yet). I don't know also if the webview can handle the website programmed login-logout with $_SESSION php parameters.
I would really appreciate some guidance.
Thanks in advance,

App tutorial or guide in Sencha Touch

I've been trying to find some info about this but the combination of words just doesn't help as it just so I figured I'd might as well ask it in here.
I'm developing a sencha touch app and I want to show the user how to use my app. But those messages should obviously only be displayed on the app's first run. Does any of you have any idea of how to achieve this in sencha touch?
Haven't tried anything as I have no idea where to start and as I mentioned earlier looking this up on google just returns tutorials about Sencha Touch.
you can set a flag and save it to the localstorage.
On every app launch you can check for that flag and only create the guide view if needed

Need a way to alert users when building spotify app

I'm building a spotify app that does some work in the background and should then alert the user if it finds a match. I can't find a way to notify the user on the main plane when I have found something of interest.
I'd like to have something like a counter on my app name or some form of notification in order to alert the user that something has changed in my app and that they should come to the app.
Does anyone know if this is possible ?
thanks,
Sean
You would need to notify them via Facebook, Spotify doesn't allow you to identify the individual users on the Spotify platform through the api.
Also there is the issue of that your App unloads after 60seconds of the user not being on the App Pane (off in a playlist etc).
So whilst a counter icon that you suggest would be wonderful.
The App Unload-er needs to go away first.

The Facebook API on iOS is meant to redirect the user on the Facebook app (or website when the app is missing) in order to grant access for the like itself. This needs to be done at least once.
In order to gather information about who is liking what you can set up whatever log or backend functionality to the Facebook app that you have to create to activate the like functionality on your iOS app.
