Firebase Realtime Database adalah database yang dihosting di cloud. Data disimpan sebagai JSON dan disinkronkan secara realtime dengan setiap klien yang terhubung. Ketika Anda mem-build aplikasi lintas platform dengan SDK Android, platform Apple, dan JavaScript kami, semua klien Anda menggunakan satu instance Realtime Database yang sama dan secara otomatis menerima perubahan data terbaru.
Kita dapat menggunakan URL Firebase Realtime Database apa pun sebagai endpoint REST. Yang perlu kita lakukan adalah menambahkan .json ke akhir URL dan mengirimkan permintaan dari klien HTTPS favorit kita.
Membuat Akun
Pertama, daftar untuk mendapatkan akun tanpa dikenakan biaya di Firebase console. Aplikasi Firebase baru akan dibuat untuk Anda dengan URL unik yang diakhiri dengan firebaseio.com. Anda akan menggunakan URL ini untuk mengautentikasi pengguna dan untuk menyimpan serta menyinkronkan data ke database aplikasi Anda.
Di dalam Firebase console, Anda dapat membuat, mengelola, dan menghapus aplikasi Firebase. Anda dapat melihat dan memodifikasi database aplikasi Anda secara real time dengan mengklik aplikasi Firebase tertentu. Di dasbor aplikasi, Anda juga dapat menetapkan Firebase Realtime Database Security Rules, mengelola autentikasi aplikasi, men-deploy, dan melihat analisis.
Membuat Database
Buka bagian Realtime Database di
Firebase console.
Anda akan diminta untuk memilih project Firebase yang ada.
Ikuti alur kerja pembuatan database.
Pilih mode awal untuk Firebase Security Rules Anda:
Mode pengujian
Cocok untuk memulai dengan library klien seluler dan web,
tetapi memungkinkan siapa pun untuk membaca dan menimpa data Anda. Setelah melakukan pengujian, pastikan untuk meninjau bagian Memahami Aturan Firebase Realtime Database.
Untuk mulai menggunakan Web, Apple, atau Android SDK, pilih mode pengujian.
Mode terkunci
Menolak semua pembacaan dan penulisan dari klien seluler dan web.
Server aplikasi terautentikasi masih dapat mengakses database Anda.
Pilih lokasi untuk database.
Bergantung pada lokasi database, URL untuk database baru akan memiliki salah satu format berikut:
DATABASE_NAME.firebaseio.com (untuk database di us-central1)
DATABASE_NAME.REGION.firebasedatabase.app (untuk database di semua lokasi lain)
Klik Done.
Saat Anda mengaktifkan Realtime Database, API di
Pengelola Cloud API juga akan aktif.
Memilih Library Helper
Anda bisa membaca dan menulis data melalui REST API langsung dari command line.
Dalam panduan ini, kami akan menggunakan cURL untuk semua contoh. Kami juga memiliki beberapa library helper pihak ketiga untuk berinteraksi dengan REST API dari bahasa pilihan Anda. Anda bisa menggunakan salah satu library helper berikut atau membuatnya sendiri:

Data is stored as\nJSON and synchronized in realtime to every connected client. When you build\ncross-platform apps with our Android, Apple platforms, and JavaScript SDKs,\nall of your clients share one Realtime Database instance and automatically receive\nupdates with the newest data.\n\nWe can use any Firebase Realtime Database URL as a REST endpoint. All we need\nto do is append `.json` to the end of the URL and send a request from\nour favorite HTTPS client.\n\nCreate an Account\n\nFirst sign up for an account at no cost in the [Firebase console](//console.firebase.google.com/). A new\nFirebase app will be created for you with a unique URL ending in\n`firebaseio.com`. You'll use this URL to authenticate your users and\nto store and sync data to the app's database.\n\nWithin the [Firebase console](//console.firebase.google.com/) you can create, manage and delete Firebase\napps. Clicking on a specific Firebase app lets you view and modify your app's\ndatabase in real time. In your app dashboard, you can also set\nFirebase Realtime Database Security Rules, manage your\napp's authentication, deploys, and view analytics.\n\nCreate a Database\n\n1. Navigate to the **Realtime Database** section of the\n [Firebase console](https://console.firebase.google.com/project/_/database).\n You'll be prompted to select an existing Firebase project.\n Follow the database creation workflow.\n\n2. Select a starting mode for your Firebase Security Rules:\n\n Test mode\n\n : Good for getting started with the mobile and web client libraries,\n but allows anyone to read and overwrite your data. After testing, **make\n sure to review the [Understand Firebase Realtime Database Rules](/docs/database/security)\n section.**\n\n :\n | **Note:** If you create a database in Test mode and make no changes to the default world-readable and world-writeable Rules within a trial period, you will be alerted by email, then your database rules will deny all requests. Note the expiration date during the Firebase console setup flow.\n\n : To get started with the web, Apple, or Android SDK, select testmode.\n\n Locked mode\n\n : Denies all reads and writes from mobile and web clients.\n Your authenticated application servers can still access your database.\n\n3. Choose a location for the database.\n\n Depending on the\n [location of the database](/docs/projects/locations#rtdb-locations), the\n URL for the new database will be in one of the following forms:\n - \u003cvar translate=\"no\"\u003eDATABASE_NAME\u003c/var\u003e`.firebaseio.com` (for\n databases in `us-central1`)\n\n - \u003cvar translate=\"no\"\u003eDATABASE_NAME\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e`.firebasedatabase.app`\n (for databases in all other locations)\n\n4. Click **Done**.\n\nWhen you enable Realtime Database, it also enables the API in the\n[Cloud API Manager](https://console.cloud.google.com/projectselector/apis/api/firebasedatabase.googleapis.com/overview).\n\nChoose a Helper Library\n\nYou can read and write data through the REST API directly from the command line.\nIn this guide we'll use [cURL](https://en.wikipedia.org/wiki/CURL)\nfor all of our examples. We also have several third-party helper libraries for\ninteracting with the REST API from your favorite language. You can use one of\nthe following helper libraries or create your own: \n\n| Language | Libraries |\n|----------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| Clojure | [taika](https://github.com/cloudfuji/taika) by [Cloudfuji](https://github.com/cloudfuji/) |\n| Dart | [IO Client](https://github.com/firebase/firebase-dart#io-client) in the official [firebase-dart](https://pub.dartlang.org/packages/firebase) library |\n| Go | [Firego](https://github.com/zabawaba99/firego) by [Steven Berlanga](https://github.com/zabawaba99) and [Tim Gossett](https://github.com/MrGossett) [Go Firebase](https://github.com/JustinTulloss/firebase) by Cosmin Nicolaescu and Justin Tulloss |\n| Java | [firebase4j](https://github.com/bane73/firebase4j) by [Brandon Gresham](https://twitter.com/bane73) |\n| Perl | [Firebase-Perl](https://metacpan.org/pod/Firebase) by Kiran Kumar and JT Smith |\n| PHP | [firebase-php](https://github.com/kreait/firebase-php) by [kreait](https://github.com/kreait) [firebase-php](https://github.com/ktamas77/firebase-php) by [Tamas Kalman](https://github.com/ktamas77) |\n| Python | [Pyrebase](https://github.com/thisbejim/Pyrebase) by [James Childs-Maidment](https://github.com/thisbejim) [python-firebase](http://ozgur.github.io/python-firebase/) by [Özgür Vatansever](https://github.com/ozgur) [python-firebase](https://github.com/mikexstudios/python-firebase) by [Michael Huynh](https://twitter.com/mikexstudios) |\n| Ruby | [firebase-ruby](https://github.com/oscardelben/firebase-ruby) by [Oscar Del Ben](https://twitter.com/oscardelben) [BigBertha](http://derailed.github.io/bigbertha) by [Fernand Galiana](https://twitter.com/kitesurfer) [rest-firebase](https://github.com/CodementorIO/rest-firebase) by [Codementor](https://www.codementor.io/) |\n\nNext Steps\n\n- Learn how to [structure data](/docs/database/rest/structure-data) for Realtime Database.\n- [Save data.](/docs/database/rest/save-data)\n- [Retrieve data.](/docs/database/rest/retrieve-data)\n- [View your database in the Firebase console.](https://console.firebase.google.com/project/_/database/data)"]]
