Google Firebase firestore error.

Question

Hay friends tomorrow I studied about Google firebase and firestore database. And tried my best to create a code

https://code.sololearn.com/WdyqpbZsKb9J/?ref=app

This code very very nicely when it was created but after that daily quota limit riches. So I made another account with another firebase I'd to maintain it but its limit also riched within no time .

See the above image actually the reading data limit is reached see another image below
https://ibb.co/1K5Nm40

So I want to ask
1). What is this reading limit
2). How it works
3). The most important thing. How can I prevent this type of frustrating problem.

Help me please if you can . Fast 🙏🙏

And surprised to see only 111 peoples writen data there then how reads exceeded that much.

Answer 1

How are you reading the list of messages (exact process). Are you extracting the complete list at once or you are doing it one-by-one for each message. And I also saw setInverval in your code, are you doing it multiple times?

Answer 2

you can dm for security based things.

Answer 3

You can host it somewhere else and access it using script src+ some sort of integrity check that might not be reproducible. You might create an md5 digest of window.location.href(since it would be constant and unique for your code) and use it as a key to access your key (which is stored at a server).

Answer 4

Firebase itself is real-time, listening to a Web Socket alike signals.

Once connection established, no need to use setInterval to get it again.

Answer 5

Maybe thats what caused so many read ops. Another very rare possibility is a DOS(very.rare.).

Answer 6

DOS(Denial Of Service) is a typical attack(by a hacker of course), in which the attacker overloads your host computer a lot of requests to it(humongous amount). Since your api keys are visible in your code it is possible that someone might have just copied the key and performed a DOS using it. Although chances of this is very rare as we dont encounter hackers on regular basis, and most of them wont do such mischief.

Answer 7

Hmm good I guess might have a solution to your visible key problem

Answer 8

Kkk. I am not expert Lord Dev. I dont know thse all things ☹☹

Answer 9

May be. Actually I am getting the whole data once Lord Dev and keep refreshing data by getting it again and again so that if anyone enters some value so it automatically get into the list. I think the setInterval is creating the problem as I read the data continually

Answer 10

Hmm but last time some one did using for loop added exexs of data Lord Dev ☹☹. I had seen my firestore that time . Actually it is my second account for firestore

Answer 11

That person unknowingly did an DOS😅.
I still see daily quota error on your code.
Then most probably the setInterval is causing the DOS.

Answer 12

Hmm may be let me fix it Lord Dev

Answer 13

I dont think so Lord Dev . Because I will need the key at any cost to proceed in my code. There is no alternative for it I think.

Answer 14

What is this DOS Lord Dev . ☹☹

Answer 15

Now take a look Lord Dev. I created a situation in which the code will only get refreshed when user add data. for its proper functionality we need to wait I think while it get data back .

Answer 16

Answer 17

Fixed Lord Dev. Have a look to my new code
