Firebase is an all-in-one backend as a service provider (BaaS) that provides database, authentication, cloud storage among their many services. In ...

Excuse me if I've missed something. But surely having your API key inside the create-react-app will expose your backend to abuse.
Someone with knowledge of JavaScript could easily find the API key within your code and use the key to write whatever they want to the database?
Oh none at all, you're right on point. I've also wondered the same thing until I came to this post:

I won't put anything into my Firebase project except for this tutorial, so for all purpose I think it will be fine.
It is safe to include the config in your app. The Firebase docs address this:
I ran into an issue with Firebase to where whenever my e.preventDefault() is right after my onSubmit handler, it will not add data to my db in prod. It works fine in development which is odd. Check out what I wrote:
onSubmit = e => {
e.preventDefault();
const { fullName, email, subject, message, error } = this.state;
let contactID = email;
db.collection("formContacts")
.doc(contactID)
.set({
fullName: fullName,
email: email,
subject: subject,
message: message
})
.then(
(window.location = "/formSuccess").this
.setstate({ ...INITIAL_STATE })
.catch(
(window.location = "/formError").this.setstate({ ...INITIAL_STATE })
)
);
};
Any thoughts?
Hello Robert, sorry for late reply. I don't know what's wrong by simply looking at your code. There may be several causes for it. I recommend you try these suggestions:
Does the
catchcall ever run when you do it?Or maybe you had the wrong credentials for production environment?
If you don't have any React error in the console, most likely something is wrong in the process of saving your data to Firebase.
Hope this helps!
Thanks for the clear tutorial Nathan.
Is it possible to connect a front-end-only react app to firebase WITHOUT using "test" mode. I've been struggling to successfully connect my react apps to firestore other than through "test" mode. Any help would be greatly appreciated. Also, i'm fairly certain other people have similar concerns as there isn't much on stack overflow, reddit, etc. to answer this question
A good tutorial.
Very handy, thanks for taking the time to write this up!
NOICE
waiting for new posts
i am getting error while putting the mine keys of firebase project, so how to solve it?
What error did you see in the console? It might be something with the security rule
Good tutorial and very useful. It works well in develop mode but during production build, it says something like:
"Reference error: IDBIndex is not defined" and cancels the build
Thanks for the article!
Is this going to be a series? Are you planning to write about Firebase as an authenticator?
Thank you Sandor! I actually haven't taught about that.. you just give me a new idea! I will try to come up with a more advanced Firebase integration. Stay tuned!
