As I needed to authenticate the user of an app, I’ve chosen for something the most straightforward possible, so I thought using Firebase would be a good fit.
So, I ran into the docs (I’m skipping the prerequisites here for the sake of concision):
Create a password-based account
Sign in a user with an email address and password
Handle the sign-in flow with the Firebase SDK
So I succeed to send an authentication request with login/pass and Google.
So now, correct me if I’m wrong, but, I think I need to make the following steps:
-
Pass a session_ID to my back-end (a svelte endpoint call by a classic http post request I suppose).
-
Then, the back-end can store the session_ID in a database associated with the corresponding user_ID
-
Call a function on each private page of the back-end that will check if the session_ID provided by the front-end exists, then serve the page or redirect the user.
The thing is … I get a huge object back from Firebase Auth and I have to confess that I’m a little lost here… You can see below what I get back when I sign-in with an account using both login/pass and Google authentication.
Which ID am I supposed to take as a session_ID and which one as a user_ID ?
I can see:
accessToken & refreshToken in the stsTokenManager propertyaccessToken & refreshToken in the credential propertyidTokenuid or Google authuid for login/Pass authuid for I don’t know (see “proactiverefresh”)federatedIdrawIdlocalID
…
Thank you for your help 🙂
