B4J Library [BANanoFireStoreDB] - A CRUD Cloud FireStoreDB Wrap for BANano



Yesterday I started playing around Google FireStore. This is things I learned. So, you need to log to the console and do the initial setup.

There is a Realtime Database (FireBase) and there is a Cloud FireStore. This is about the latter.

Cloud Firestore is a flexible, scalable database for mobile, web, and server development from Firebase and Google Cloud Platform. Like Firebase Realtime Database, it keeps your data in sync across client apps through realtime listeners and offers offline support for mobile and web so you can build responsive apps that work regardless of network latency or Internet connectivity. Cloud Firestore also offers seamless integration with other Firebase and Google Cloud Platform products, including Cloud Functions.

Here is a very simplified method of setting up firebase storage

  • Go to firebase console
  • click add project
  • specify project name > Continue
  • enable / disable google analytics > Continue / create project
  • Your project Is ready > Continue
  • Side Menu > Develop > Authentication
  • Set up sign-in method
  • Sign in method > Email/Password (click edit icon) > Enable > Save

  • Side Menu > Develop > Cloud Firestore
  • Create database
  • Start in test mode > Next
  • Select location > enable
  • Side Menu > Project Overview > Project Settings
  • Your apps > web
  • Enter App NickName > Register App
  • Add Firebase SDK = Connection settings (copy)
  • Continue To console

Step 1.

Step 2.
Create your database. Ensure that you update your permissions as they are set to False (cannot read, cannot write). https://firebase.google.com/docs/firestore/security/get-started#auth-required

More details: https://firebase.google.com/docs/firestore/quickstart

Step 3
Get your connection configuration data. This you will use on the attached library / class

Step 4
Create a collection. I have created a collection called users for my tests. This will be used for CRUDing around.

What has been done

1.1 Adding records to a collection.
1.2. Updating an existing record in a collection
1.3. Reading an existing record from a collection
1.4. Reading all records from an existing collection
1.5. Deleting a record from a collection.
1.6. Work Offline with enablePerist...
1.7. Real-time change detection (changes made by other users to the collection)

How was the Learning Curve?

Once you get around BANano.RunMethod, BANano.GetField and how these can be used with the JavaScript FireBase, all is well.

  • BANano.RunMethod is used to execute a function.
  • BANano.GetField is like map.get(?)

Thing is FireBase uses a lot of dots (.) so its challenging to determine what is a field / function at times. It has been a trial and error exercise. For example...

'get/read a record
Sub CollectionGet(collection As String, colID As String) As BANanoPromise
    'get the collection to add to
    Dim promGet As BANanoPromise = firestore.RunMethod("collection", Array(collection)).RunMethod("doc", Array(colID)).RunMethod("get", Null)
    Return promGet
End Sub


PS: I have attached the first tests here, this is WIP (work in progress) and more is being done to wrap an easy db functionality for CRUD.

I'm just running the application which you have provided as demo. i have not updated anything.
I has asked you before which example are you running and you did not respond to that.


so again..

Q1. Which example are you talking about between the two?

As a follow up question

Q2. Did you follow all the steps in setting up firebase on the google developer console for your account as explained in the first post video? The code in these posts should work without hustles as long as everything in setting up your account is done properly. I am of the assumption that there is something you have not done right in setting up your account. I have ran both examples on my side and still I CANNOT REPRODUCE YOUR ERROR, that is why I said comment the line out to see what happens.
