How to access admin.auth()?

Is it even possible to access the admin object from the migration script?

I want to change some filed names inside customUserClaims, so I thought it would be nice to create a migration for that. But for doing that I would need to access admin.auth().listUsers() and then run setCustomUserClaims() for each individual user.

I’ve added const admin = require("firebase-admin"); before the script, which amazingly worked, but that feels like a workaround and not a proper solution.

I would suggest adding admin object to MigrateOptions

Hi. In my case, the fireway app.auth() (v1.0.2) was failing using emulator even with --forceWait as suggested by @dsvgit (even with the --dryRun switch). I was getting the following error

FirebaseAuthError: Failed to determine project ID for Auth. Initialize the SDK with service account credentials or set project ID as an app option. Alternatively set the GOOGLE_CLOUD_PROJECT environment variable. at FirebaseAuthError.FirebaseError [as constructor] hereunder my command line to start the migration FIRESTORE_EMULATOR_HOST=localhost:8080 yarn fireway migrate --require=ts-node/register --forceWait --dryRun

I end up configuring my env using these two variables:

GCLOUD_PROJECT=myproject FIREBASE_AUTH_EMULATOR_HOST=localhost:9099

Local migration using ‘app.auth’ works properly with the emulator now !

app property which is provided by fireway seems like works for me

• --dryrun option doesn’t work for auth updates (only for firestore)
• I had to use --forceWait option to make it works

const clearClaims = async (auth, authUser) => {
  if (authUser.customClaims) {
    return await auth.setCustomUserClaims(authUser.uid, null);
  }
};

const updateClaims = async (auth, authUser, changes) => {
  const newCustomClaims = { ...authUser.customClaims, ...changes };
  return await auth.setCustomUserClaims(authUser.uid, newCustomClaims);
};

module.exports.migrate = async ({ firestore, app }) => {
  const auth = app.auth();

  const usersSnapshot = await firestore.collection("users").get();
  usersSnapshot.forEach(async (snapshot) => {
    const userId = snapshot.id;
    try {
      const authUser = await auth.getUser(userId);

      // await clearClaims(auth, authUser);
      // console.log(authUser.customClaims);

      await updateClaims(auth, authUser, { admin: true });
    } catch (error) {
      // console.log(error, userId);
    }
  });
};
