Modular Firebase Admin Database

Is there or will there be modular Firebase Admin Database functions i.e. update(), get(), set(), ref() etc.? Maybe there is a workaround?

Else I would have to code equal functions twice, like "craftBuilding()" on server (admin) and one for client.

Tried to:

import { getDatabase, ref, set, update, child, onChildAdded } from 'firebase-admin/database';

Error:

The requested module ‘firebase-admin/database’ does not provide an export named ‘ref’

I expected to be able to use firebase rtdb functions like on client-side, to not code identical functions twice.

    Since Firebase Admin is namespaced, ref is available after you initialize.

    import { ref, update, set } from '@path/yourAdminFunctions';

var admin = require("firebase-admin");

// Initialize Admin SDK

var db = admin.database();
export db;

const dbReference = ref("your reference here");
const IDSnapFromQuery = query(dbReference, ["ID", "==", 10]);

    You could modularize it yourself by creating functions for the operations you require in a separate file:

    import { db } from '@path/yourMainFile';

export function ref(databaseReference) {
  return db.ref(databaseReference);
};

// for query pass in the db.ref instance you're using
export function query(dbReference, queryParams) {
  // identify what query params are e.g. ID == 10 in this example
  // note that you will have to code the queryParams filter, I have left it out

  dbReference
    .orderByChild('ID')
    .equalTo(10).on('child_added',
  (snapshot) => {
    return snapshot;
  });
}

// do the same for update, set etc

    You can read more on the admin SDK documentation.

    The Admin SDK is not totally modular yet but has some function such a getDatabase() starting V10.

    import { getDatabase } from 'firebase-admin/database';
// TODO: Initialize Admin SDK

const db = getDatabase();

// usage
const ref = db.ref('../../..')

    I would recommend using latest version of the SDK along with the existing syntax but use newer modular imports.
