Experiencing a glitch with the Realtime Database feature on Firebase

    // db.js file

    import * as firebase from "firebase/app"
    import "firebase/database"

    const config = {
        apiKey: "" ...
    }

    const db = firebase.initializeApp(config)
    export default db

    // App.vue file


    import { reactive, onMounted, ref } from 'vue'
    import db from "./db.js";

    const SendMessage = () => {
          const messagesRef = db.database().ref("messages")

          if(inputMessage.value === "" || inputMessage.value === null) {
            return
          }

          const message = {
            username: state.username,
            content: inputMessage.value
          }

          messagesRef.push(message)
          inputMessage.value = ""
        }

I am working on a chat application using Vue.js and Firebase. However, I encountered an issue when trying to send a message: db_js__WEBPACK_IMPORTED_MODULE_1_.default.database is not a function at Proxy.SendMessage (App.vue?3dfd:63:1)

I suspect the problem lies in the way I imported the database module, but even after attempting to switch to version 9 of Firebase, the error persists.

Firebase V9 embraces a functional approach, which is evident in the way Firestore interactions are handled. I typically receive an indicator if something isn't functioning as expected.

db.js

import { initializeApp } from 'firebase/app';
import { getDatabase, ref, push, child, serverTimestamp } from 'firebase/database'

const config = {
  apiKey: "" ...
}

const firebase = initializeApp(config)
const db = getDatabase()

function addMessage(path, message) {
  message.createAt = serverTimestamp() // The database will automatically assign the current timestamp to this field for sorting purposes.
  return push(child(ref(db, path)), message)
}
export { addMessage }

App.vue file

import { reactive, onMounted, ref } from 'vue'
import { addMessage } from "./db.js";

const SendMessage = async () => {
  if (!inputMessage.value) return 
  // The above line checks if the value is empty or null by returning false and using ! to convert it to true.

  const message = {
    username: state.username,
    content: inputMessage.value
  }

  const result = await addMessage('path to data in tree', message)
  // The async/await syntax ensures that the code waits for the data to be saved in the database before proceeding.
  console.log(result.key) // If awaited, the result can be accessed if it's not void.
  inputMessage.value = ""
}

If you're using ref() in .vue files, remember that database operations outside of vue files utilize the same ref() function but with different functionality. You also have the option to rename functions during import like so:

import { ref as dbRef } from 'firebase/database'
