Tips for storing a string or object in a Firebase database

I'm looking for some guidance on how to save a string or object to the Firebase database using JavaScript. I'm currently trying to do this on codepen.io. Here's what I've attempted so far:

// Setting up Firebase app

const firebaseConfig = {
  // Your app configuration goes here
};

firebase.initializeApp(firebaseConfig);

// Accessing the database

const database = firebase.database();

// Adding a string to the database

const myString = "Hello, Firebase!";

database.ref('myData').set(myString);

However, I'm not seeing any new data in the Firebase console. What steps am I missing? Any help would be appreciated.

Answer №1

It appears that the firebaseConfig you provided is empty. Please fill in your Firestore information as shown below:

  const firebaseConfig = {
      apiKey: "YOUR_API_KEY",
      authDomain: "YOUR_AUTH_DOMAIN",
      projectId: "YOUR_PROJECT_ID",
      storageBucket: "YOUR_STORAGE_BUCKET",
      messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
      appId: "YOUR_APP_ID"
    };

I encountered difficulty using it in Codepen, so I created a basic javascript project and tested it with node.js.

If Firebase is not already added to your project, please follow these steps:

npm install firebase

Ensure you import the necessary libraries into your project:

import { initializeApp } from "firebase/app";
import { getFirestore, collection, getDocs } from 'firebase/firestore/lite';

Finally, establish connection to the collection and handle data read/write operations like this:

const testCol = collection(db, 'TestCollection');
const testSnapshot = await getDocs(testCol);
const testList = testSnapshot.docs.map(doc => doc.data());
console.log("Test list",testList);
