I need some technical design guidance on how to do this.
I have a webapp that is build on ReactJS and I have a Firebase Database
I would like to update realtime data from Firebase Database updated to the ReactJS UI (filtered to particular user/account)
I know that we can listen to Firebase Database events from Functions using these guidance:
https://firebase.google.com/docs/functions/database-events
Can reactJS subscribe to certain events from function to get these triggers ?
I would like real-time information appearing on the ReactJS page. Can someone advise how would this be designed / architectured ? Thanks

Both the two database services offered by Firebase, i.e. Firestore and the Realtime Database, offer the possibility to get realtime updates from the database in your front-end.
For Firestore, you'll find here in the doc the details on how to listen to a Document, a Query or an entire Collection.
For the Realtime Database you'll find here in the doc the details on how to listen to a specific node of the JSON-like data tree.
So, in the Firebase world, setting such real-time listeners is the standard way for having "real-time information appearing on the ReactJS page".

This is about triggering a background Cloud Function in the Google Cloud back-end, based on some events occurring in the database (e.g. update, deletion or creation). In this framework, there is no out-of-the-box mechanism to be informed, from your front-end, that such a background Cloud Function was triggered (based on some changes in the database).
I am new to app development and I am thinking about creating an app which will store all the anime that you are currently watching or have watched in the past. The purpose of this app is to store your progress of an anime/manga so that if you forget which chapter you were on the last time you watched/read the anime or manga.
My plan is to connect this app to myanimelist website and use its feature on my app to find an anime. Then if the user adds the anime to his watch-list then it will store the important data e.g., name, description, author, Image.
I am totally new to app development and I have to create an app for the final year project. As on how to start the app or the resources required I am at loss.
The main topic of my concern is on how I should handle the use of website data or the connection to the database. Is something like using SQL queries? Which database should I use to store the data on local device?
Any help is appreciated.
Your questions
how I should handle the use of website data or the connection to the database.
if You have an API that you are using for your website, then you can use that API to fetch data in your flutter app.In case your don't have an API you have to create one for your app.
Which database should I use to store the data on the local device?
For storing data to the local device you can use sqflite package for flutter to store data. Using sqflite you can write simple SQL queries to fetch or store data in the
database.
Ask if you have any problems.
According to this answer, I want to use an offline first db inside my electron app. I nedd that the users are not able to directly modify the database, but they can only read data using the UI. The data needs to be synced with a master remote client app that will add and modify data. Can anyone suggest me a good database library to do this?I have a pusher account and an heroku one, that can be used to pass the data between the clients, but first I need a way to store them into the app
I'm currently working on a React Native application, the server is already implemented and my app should implement offline sync, I'm planning to integrate realm on the mobile device to deal with the offline data and pushing the data to the implemented server when the device is online. How would I go about doing that?
I'm trying also to make some kind of offline sync. A calendar app that works offline.
I'm developing it on ionic 4 using sqlite.
Basically, what I did is: I keep a variable with my last update timestamp.
Part 1
Get activities.
A service is running on the background, getting from the backend activities that their creation timestamp is later than the mobile last update timestamp.
Part 2
Every time the user create an activity I add the timestamp to the activities table and a flag called synced that is true / false.
Another service scans the table for synced === 'false' and does the POST request.
Hope I helped.
I am new to web development. I want to develop a web application using angularJS, nodeJS, Express and couchdb. The registered user will be given some tasks. So the app must maintain data of tasks assigned to a user and tasks completed by the user. It should also maintain the data of users when they register for this app.
**I am able to access data(user name,tasks assigned to user,tasks completed by user) from couchdb through nodejs. But I don't know how to make angularjs access the data accessed by nodeJS and display it on web page. I would like to know how to access that data and display it on webpage.**You can take tasks as repairing a chair or something.
