QUESTION
I encountered a problem in my chat app.
I works when I post message doc to the messages col but then I'm trying do getDocs back and render them I get an empty array.
I looked through FB docs, and I didn't notice any mistakes on my part. I also read an article where I was advised to use the react-firebase library with useCollectionData with which I had the same result.
...ANSWER
Answered 2022-Mar-30 at 21:33In the query, you're trying to orderBy timestamp
. That's not a field you're creating in sendMessage
.
When a value you're ordering by doesn't exist on the document, it won't return.
Maybe you meant to orderyBy the createdAt
value.
QUESTION
I'm receiving the maximum update depth exceeded on some random occasions. I am using the useEffect hook to navigate the user to the login screen when not authenticated, and navigate him into the home page when he is authenticated and tries to access the login screen. I am getting the user from firebase useAuthState.
Here is the login page code
...ANSWER
Answered 2022-Mar-28 at 14:55This is happening because from login
page it's redirecting user to home
page when there is a change in user, loading, navigate
any of these value and from home
page it's redirecting user to login
page when there is a change in above mentioned value so basically it's going in infinite loop.
So change the dependency array in both the components:

I'm using Google firebase v9. On the first sign in, usually there would be a pop up for user to choose which email to sigh in with, but for some reason, when I sign in, it automatically send me to the chat page automatically. I tried delete user in my firebase app and tried again and get the same result. What am I doing wrong?

...ANSWER
Answered 2022-Mar-15 at 13:23It sounds like your app is already associated with your Google account. Signing out does not sever that association.
Removing that association is described in the Remove third-party account access, but mostly consists of going to the list of Third-party apps with account access and removing your app from that list.
If that doesn't do it, have a look at the results on forcing the account picker to show up.

I'm trying to query a collection using useCollectionData
with a where
query. However, it always returns undefined

Am I missing something?

I am using react-firebase-hooks https://github.com/CSFrequency/react-firebase-hooks/tree/v4.0.2/database#full-example
Below is values return when I console.log(v.val()) and when I do console.log(v.val().name) it's undefined.
...ANSWER
Answered 2022-Feb-18 at 13:19That is because v.val()
is an object of objects, and as you are interested in the name
, you need to get the values of the first object and then map through it and hence access the name
.
QUESTION
I'm trying to update some Firebase code in a React project to the new modular web v9 sdk that Firebase released recently. The project being upgraded uses the react-firebase-hooks hook useCollectionData()
, which fails upon changing to the new sdk. I get the following error output in my console 3 times when I try to run my ported code.
index.esm.js:101 Uncaught TypeError: v1.isEqual is not a function
A minimal example of working web v8 code:
...ANSWER
Answered 2021-Nov-03 at 11:52React Firebase Hooks v4 has been released which supports v9 and also requires React 16.8.0 or later and Firebase v9.0.0 or later.
The React Firebase Hooks library doesn't seem to support Firebase Modular SDK yet (last release April 2021). You might have to use compat
version which allows to use older name-spaced syntax even in v9.0.0+
and does not have benefits of tree-shaking :
QUESTION
I was following this tutorial https://www.sitepoint.com/reddit-clone-react-firebase/.
Earlier it was really simple just call onSnapshot after the document is fetched, but here it is a separate function, and now here comes the issue, when I try to call that onSnapshot by passing document, but it always says,no matter what type of data I tried to pass it as the first param, it always says, it is not type of 'bc' which it expects.
...FirebaseError: Expected type 'bc', but it was: a custom he object
ANSWER
Answered 2022-Jan-02 at 05:52These kind of errors occur usually when the functions aren't used the way they're supposed to. I can't really tell where the problem comes from in your code but you may try the getDocs
method instead and a state variable
to store your values
try this code.
