Node js RESTFUL API with Firebase as database-CodePudding

We have a graduation project and we decided make an app with flutter.We thought we can use firebase authentication and database storage for data that come from node js api but I could not find any example of it. I saw flutter apps with MongoDB/Node and Express js api. Is that possible to make an app with using firebase and API has been made by node js? If you know a source for learning of it please share it I'll be grateful Thank you.

CodePudding user response：

You can start with installing firebase to your project

npm install firebase

Here is an example of code provided by Google

// Get a database reference to our posts
 const db = getDatabase();
 const ref = db.ref('server/saving-data/fireblog/posts');

 // Attach an asynchronous callback to read the data at our posts reference
 ref.on('value', (snapshot) => {
    console.log(snapshot.val());
 }, (errorObject) => {
     console.log('The read failed: '   errorObject.name);
 });

I made it in one of my projects so recommend you read the docs

https://firebase.google.com/docs/web/setup

Update

So you need to set up your firebase project Follow instruction here https://firebase.google.com/docs/database/web/start

Now second thing is how to add firebase to you node.js express project

const { initializeApp } = require("firebase/app");
const { getDatabase, ref, set, onValue } = require("firebase/database");


// Set the configuration for your app
// TODO: Replace with your project's config object
const firebaseConfig = {
    apiKey: process.env.YOUR_VALUE_FROM_DOT_ENV_FILE,
    authDomain: process.env.YOUR_VALUE_FROM_DOT_ENV_FILE,
    databaseURL: process.env.YOUR_VALUE_FROM_DOT_ENV_FILE,
    projectId: process.env.YOUR_VALUE_FROM_DOT_ENV_FILE,
    storageBucket: process.env.YOUR_VALUE_FROM_DOT_ENV_FILE,
    messagingSenderId: process.env.YOUR_VALUE_FROM_DOT_ENV_FILE,
    appId: process.env.YOUR_VALUE_FROM_DOT_ENV_FILE

};
const firebase = initializeApp(firebaseConfig);

// Get a reference to the database service
const database = getDatabase(firebase);

All this things you will get from firebase account

Now Express section here is part of example

app.post('/items', (req, res) => {
   const postData = req.body;
   const db = getDatabase();
   const ephemeralId = Date.now().toString();
   set(ref(db, 'items/'   ephemeralId), postData).then(_r => {
       res.status(201).send({
           success: true,
           insertedId: ephemeralId,
       });
    }).catch(err => {
       res.status(420).send(err);
    });

   });

And as I promised here is full code on git https://github.com/labadze/node-express-firebase-database-api/tree/master
