Firebase Firestore

“Now we are going to secure the fire store database later on using something called fire store rules which would prevent this kind of thing from happening but I also want some kind of elegant solution on the front end as well and to do that we're going to use queries and a query is going to make us or allow us rather to fetch only notes created by the currently logged in user.”

“In this lesson, I'm going to show you how we can delete documents from a fire store collection.”

“And for now, I want to set that equal to a function called onSnapshot which we need to import from the Firebase package.”

“We've seen now how to add documents to a collection in Firestore, and I've gone ahead and added just a few more off screen by filling out the form a few times and then just submitting it.”

“So in the previous lesson we set up a new fire store database on the Firebase back end and we also initialize that service on the front end. So now then we can start using the fire store SDK to do things like save a new document to a collection or retrieve documents and so on.”

“So, now I would like to move on to another Firebase service that we'll be using, the Firestore database, which is a real-time no SQL database that's really easy to use and set up.”

“So until Firebase figures out whether we're logged in or not, then it doesn't show that template.”

“But, I also wanted to show you another way that you can access the current user by using a property directly from the Firebase SDK.”

“And by the way, that type for a Firebase user is imported from the Firebase SDK.”

“And then after the await keyword we're going to fire or rather use a Firebase function called sign in with email and password. And when you see that option over here, just click on it to make sure it gets imported from the Firebase SDK.”

“So, the first Firebase service that we're going to use in our application is the authentication one, which allows us to sign users up, uh log them out, log them back in, et cetera, all from our front-end application.”

“So, first of all, back in our project, I'm going to open up a new terminal and then I'm going to install the Firebase um package by saying npm install Firebase and then just hitting enter.”
