Pyrebase Documentation | Cloud Maestro

Introduction

Pyrebase is a simple wrapper for the Firebase API which was written only for Python 3.(Does not Support Py 2)

Preliminaries

Have an Linux Environment(My Choice)
Have a Google Account
Create a Firebase Project in Firebase Console
Go To Project Settings and Create a Web App and get the Configurations

config = {
  "apiKey": "apiKey",
  "authDomain": "projectId.firebaseapp.com",
  "databaseURL": "https://databaseName.firebaseio.com",
  "storageBucket": "projectId.appspot.com"
}

On Your Local Computer,
- Make Sure To Create an Virtual Environment to avoid conflicts (Believe Me From Experience : There is a Conflict)
  
  python3 -m venv env
- Activate the Virtual Environment
  
  source env/bin/activate
- Install the pyrebase
  
  pip3 install pyrebase
- and Pyrebase supports Authentication, Database and Storage Services
  
  Authentication -> firebase.auth()
  
  Database -> firebase.database()
  
  Storage -> firebase.storage()
Finally Open Your Code Editor, Let's Code...!

Firebase Initialization:

After Installation of Pyrebase, Initialize your app

import pyrebase

config = {
  "apiKey": "YourApiKey",
  "authDomain": "YourProjectId.firebaseapp.com",
  "databaseURL": "https://YourDatabaseName.firebaseio.com",
  "storageBucket": "YourProjectId.appspot.com"
}

firebase = pyrebase.initialize_app(config)

Firebase Authentication:

Firebase provides authentication using passwords, phone numbers, popular federated identity providers like Google, Facebook and Twitter, and more and it improves industry standards by integrating OAuth 2.0 and OpenID Connect with the custom backend.

-> Create an Authentication

auth = firebase.auth() # Creates Authentication

-> Input From User

user = input("Enter a User")  # Input Username
password = input("Enter a Password") # Input Password

-> Authenticate the User

signin = auth.sign_in_with_email_and_password(email, password)
print("Sign In Was Successfull")

-> You can also verify the email using code

auth.send_email_verification(signin['idToken'])
print("Email Verification Sent")

->Send Password Reset Emails

auth.send_password_reset_email(email)
print("Email Sent...Check Your Inbox")

Firebase Real Time Database

The Firebase Realtime Databaseis stored as JSON and synchronized in realtime to every connected client.

-> Intialize Database


db = firebase.database()
# data
data = {
  "cloud" : "maestro"
}

->Sending Data to the Database

db.child("users").set(data)

->Update Data in the Database

data2 = {
  "cloud_maestro" : "saranmahadev"
} 
db.child("users").update(data2)

-> Get the Data from the database

users = db.child("users").get() print(users.val()) # Prints the Values of the JSON Object print(users.key()) #Prints the Keys of the JSON Object

-> To delete the data in the database

db.child("users").child("cloud-maestro").remove()

Firebase Storage

Cloud Storage for Firebase is a powerful, simple, and cost-effective object storage service built for Google scale.

-> Creating the Object

storage = firebase.storage()

-> Building Paths To Your Data

storage.child("img/newimg.jpg")

-> Uploading Images to the Storage

storage.child("img/newimg.jpg").upload("example.jpg")

-> Downloading Images from the Storage

storage.child("img/newimg.jpg").download("example.jpg")
