Integrate MongoDB with Cloud Firestore

MongoDB?

MongoDB is a document database, which stores data in the form of objects. A document in MongoDB can be considered as an object with fields and values.

It is used to build large websites very quickly. It is often used for storing web sessions and user activity. Unlike relational databases, documents in MongoDB are not related to each other; hence, it doesn’t require any join operations.

Cloud Firestore?

Cloud Firestore is a NoSQL database from Google that is designed for mobile and web apps. It is built on top of Google’s serverless cloud technpogies. App Engine and Cloud Functions.

It is the new version of Google Firebase Database. It allows you to store data quickly and retrieve it easily. It has all the tops needed to build great apps, including real-time data synchronization, offline support, and easy querying.

It is used for building complex applications, such as chat rooms, blogs, shopping sites, etc.

Integration of MongoDB and Cloud Firestore

Integrating MongoDB and Cloud Firestore is quite simple. They are both NoSQL databases, so you can easily integrate them using a simple database call.

Let’s take an example to understand how we can integrate these two databases:

Step 1. Create a cloud firestore instance with admin credentials:

localfirestore = firebase.firestore(. localclient = [email protected]:admin1123456 client = [email protected]:admin2123456 # Add project-specific variables here. Only required if using OAuth authentication. firestore_database = ‘my-database’ firestore_cplection_name = ‘my-cplection’ my_path = ‘/imdontwanttosay’ container_id = localfirestore_instance = “imdontwanttosay” step1_id = “step-1-2”

Step 2. Initialize the Cloud Firestore instance:

# Initialize the cloud firestore client client = firebase_admin(firestore_instance. # Add project-specific variables here. Only required if using OAuth authentication. administrator = os.environ.get(“FIREBASE_ADMIN”. if administrator is not None. client.initialize_app(administrator. else. print("Failed to initialize app". else. print("Please create a Firebase App with this name before running this program". exit(. # Initialize the cloud firestore client client = firebase_admin(firestore_instance. # Add project-specific variables here. Only required if using OAuth authentication. administrator = os.environ.get(“FIREBASE_ADMIN”. if administrator is not None. client.initialize_app(administrator. else. print("Failed to initialize app". else. print("Please create a Firebase App with this name before running this program". exit(. step2_id = "step-2" localclient = [email protected]:admin1123456 client = [email protected]:admin2123456 # Add project-specific variables here. Only required if using OAuth authentication. firestore_database = 'my-database' firestore_cplection_name = 'my-cplection' my_path = '/imdontwanttosay' container_id = localfirestore_instance = 'imdontwanttosay' step3_id = "step-3" next_step(. step3_id = "step-3" next_step(. step4_id = "step-4" next_step(. step4_id = "step-4" next_step(. step5_id = "step-5" next_step(. step5_id = "step-5" next_step(. step6_id = "step-6" next_step(. step6_id = "step-6" next_step(. step7_id = "step-7" next_step(. step7_id = "step-7" next_step(. step8_id = "step-8" next_step(. step8_id = "step-8" next_step(. step9_id = "step-9" next_step(. step9_id = "step-9" next_step(. step10_id = "step-10" next_step(. step10_id = "step-10" next_step(. # Add project-specific variables here. Only required if using OAuth authentication. firestore_database = 'my-database' firestore_cplection_name = 'my-cplection' my_path = '/imdontwanttosay' container_id = localfirestore_instance = 'imdontwanttosay' step11_id = "step-11" next_step(. step11_id = "step-11" next_step(. step12_id = "step-12" next_step(. step12_id = "step-12" next_step(. step13_id = "step-13" next_step(. step13_id = "step-13" next_step(. step14_id = "steps14" next_step(. step14_id = "steps14" next_step(. step15_id = "steps15" next_step(. step15_id = "steps15" next_step(. step16_id = "steps16" next_step(. step16_id = "steps16" next Step(. # Add project-specific variables here. Only required if using OAuth authentication. firestore_database = 'my-database' firestore_cplection_name = 'my-cplection' my1path= '/imdontwanttosay' containerId=localfirestor yInstance= 'imdontwanttosay' step17 End of file <stdin>. line 2. 11220 Abort trap (core dumped. python script/server .py -c config .yaml -p 8181 server Running appengine app ./script/server .py -c config .yaml -p 8181 2017 /04 /26 10 :04. 18 [runtime] INFO.
