My app send somme data to firebase storage but it is possible that the connection is off when the app want to send those data. I hear that i can achieve that by enabling local storage, i want to known how?
You can see the following site - https://www.firebase.com/docs/web/guide/offline-capabilities.html

Tl;dr.. I'm making a todo app where I store data in Firestore, and I don't want anyone to see it not even the devs from firebase console. I found many encryption pkgs that do the job, like: encrypt. My problem is how to I handle the 'encryption key'. I don't want to keep it local because in my app user can access it's account from different devices, so if the key is stored locally they cannot decrypt thus retrieve their data (notes) from the other device (i hope this makes sense). So, do I send the 'encryption key' to firestore in a seperate collection or ... how should I approache this ?
You could store the key with Firebase Remote Config and retrieve it in the app when you need it.
Firebase Remote Config is a cloud service that lets you change the
behavior and appearance of your app without requiring users to
download an app update. When using Remote Config, you create in-app
default values that control the behavior and appearance of your app.
Then, you can later use the Firebase console or the Remote Config
backend APIs to override in-app default values for all app users or
for segments of your user base.
Check out the documentation for the flutter_remote_config plugin.
I was able to configure the Firestore database in Firebase with my flutter app and also create and read documents from my collection but when I go to Firestore console I don't see the created data, also when I creat data manually I am unable to see it in my application.
I am using the test mode which means any user can read or write.
I hope someone can help me with this puzzle.
Thanks!!!
It sounds like the device/emulator that you are running on is not connected to the internet, or at least not to the Firestore servers. In that case, the client writes all local changes into a local database, waiting to send them to the server when it gets a connection. So the local app will work, but won't be able to synchronize its local cache with the database servers.
You might want to check the connection on your device, and any proxies that might exist between your app and the Firestore servers.
I have been working on a web app and I am now looking into hosting said app. This app is a client-side app for right now meaning that all of the work is being done on the clients device and it has no backend other than the web server giving the site to the user for the first time.
I was looking into Heroku but that seems expensive for my app. Then I looked into Firebase Hosting and it looks good but requires the site to have static content. For now I'm pretty sure my app fits that criteria but in the future I would like to have users sign up for accounts and then store the info they give for the app data in a database. Would do database calls to a firebase database make the app non-static/dynamic anymore?
I know I could use Digital Ocean or another server provider but I want to be able to have scaling done for me so I can just focus on the app and not the containers themselves.
It sounds like you might want to build your app with Firebase Authentication for user logins, store data in Firebase Realtime Database, and host all the content on Firebase Hosting. You could probably write the code entirely in JavaScript to run in the browser, but if you did need to write some code on the backend, you could use Cloud Functions for Firebase.
Reading Firebase's documentation it says that
Firebase Storage provides secure file uploads and downloads for your Firebase apps, regardless of network quality.
But I tried to start an upload without connection and then reconnecting, and it didn't work.
How do I enable offline capabilities for Firebase Storage ? (I already have FIRDatabase.database().persistenceEnabled = true)
Note: I'm implementing an app for iOS in Swift.
Here is the code I'm trying:
FirebaseAPI.storageRef.child("images/test.jpg").putFile(imageURL)
Can we implement Firebase for an android app, where I am registering user using Mobile number (Similar to Whatsapp). Users will be sent a code by server which is entered by user in android app to validate the user mobile number and registering him on the server.
Question : Can I use the above method in conjunction with Firebase Auth?
I was earlier going to use MongoDB for my project, but since Firebase has SYNC capabilities, it will be a better choice for storing data. Another good reason is as below:
If a client loses its network connection, your app will continue
functioning correctly.
Every client connected to a Firebase database maintains its own
internal version of any active data. When data is written, it's
written to this local version first. The Firebase client then
synchronizes that data with the remote database servers and with other
clients on a "best-effort" basis.
Very NEW to Firebase, just came to know about firebase (through Google 2016 IO).
https://firebase.google.com/docs/database/android/save-data
Firebase hosting is not for server side processing.
It stores static assets of your website as a world-class high availability CDN. So websites hosted here loads very fast. Even in high-availability scenarios.
So you have to do processing at other server which then connects with firebase and stores userinfo in realtime database.
Firebase has put limits on userinfo to be placed in directly for users auth dashboard.
For detailed userinfo, firebase realtime db is the way to go(from your processing backend to firebase realtime db).
