I think the code change is fine but I disagree a bit with the direction (but can certainly be convinced). We have our own internal data structures, and we shouldn't make an effort to make the "consumable" by our users. This makes our life more complicated and gives off the impression that we will support the output format going forward. It also convolutes the returned data, with very little additional benefit to the user.
Consider this: What does the user want when they call toJSON on a DocumentReference? They probably would prefer something like:
{
path: 'coll/doc',
firestore: {project: 'foo', database: '(default)'}
converter: null
}
over
{
path: 'coll/doc',
firestore: {project: 'foo', database: '(default)', asyncQueue: {...}, firestoreClient: {...} }
converter: null
}
The first one is more concise, provides the information the user likely needs, and is less likely to change over time.
In case you are wondering where my argument is going (and if it is going anywhere): I think we should just implement toJSON on FirebaseFirestore and call it a day. The toJSON should have enough information to help the developer distinguish it from other instances, that is - database ID and FirebaseApp (and maybe others, but select instance members).
And yes, this should also work for Firbease@exp.
FWIW, the change to FirebaseApp already follows this pattern.
Let me know if you want to talk about this more.

@schmidt-sebastian Thanks for the suggestion -- your proposal creates a much more simplified API surface and doesn't require us to maintain a bunch of toJSON() fields. I ended up only including the databaseId and settings, since the project/database fields are not available by default. I'm not sure if I should expand the individual fields or add a return type. WDYT? |

Do these four cases test different paths in a toJSON call?

Should we include the app as well? I think the developers might want to see the app name here, since it acts as the main identifier for all Firebase components.

Added app.name to the JSON.

You should also modify the Firestore and the Firebase types if you modify this (firestore-types/index.d.ts and firebase/index.d.ts)

Fixes #4258.
Adding
toJSON()on the Firebase instance breaks the circular reference betweenfirebase.app.containerand the Firestore instance. Similarly, addingtoJSON()to theAsyncQueueandExponentialBackoffallows them to be serialized despite the circular references.Some questions:
app-compat?toJSON()? I'm afraid of locking them in and causing a breaking change if we ever want to change them in the future.
