Example:
Crud Api using firebase:
Setting up firebase:-
1. Created a new project in firebase
2. Copied the SDK snippet that would help us link the firebase to our respective
application.
3. Created a firebase.utils.js file inside of src folder
4. Pasted the SDK snippet to link the firebase
Firebase.js file:-
It consists of the basic setup that is required to link the application to the firebase.
Here, fireDb.database().ref() is passing a reference to the database. This reference is
being used to implement various CRUD operations upon the collection consisting of the
required documents of the respective employee.
AddorEdit function:-
This function is triggered whenever the handlesubmit function is executed on submitting
the form.
ADD FUNCTIONALITY:
It consists of firebaseDb.child("contacts").push(obj, (err) => {} api that helps
us to create the collection using .child and .push pushes data inside that collection. It only gets executed if currentId is empty(i.e no existing user is selected) .
EDIT FUNCTIONALITY:
It consists of firebaseDb.child(`contacts/${currentId}`).set(obj, (err) => {}
api that helps us to edit an existing data of the selected user using .set method. It only gets executed if currentId is not empty(i.e existing user is selected) .
OnDelete Function:-
This function gets triggered whenever the delete button is being clicked on a particular user.
The id of that particular user is being saved inside currentId and using that the respective data of that user is being deleted.
DELETE FUNCTIONALITY:
It consists of firebaseDb.child(`contacts/${key}`).remove((err) => {} api that
helps us to remove an document from inside of contacts collection using .remove.
Storing the snapshot of the collection:-
For displaying the entire list of the employee the data needs to be stored inside of a state that would change each time with the input of the new user.
Using the firebaseDb.child("contacts").on("value", (snapshot) => {} we are getting access to the contact collection and then using the snapshot we are pulling the documents of contacts collection and storing it inside of the contact variable by setting the setContact value to the value of the snapshot.
Displaying the documents:-
After storing the real-time data from the database inside of the contact variable we are simply mapping through the Object and displaying the required datas as per the keys of each object.
