Quickstart
Back4App is an open source (based on Parse Platform), low code platform that helps you to develop modern apps. On Back4App, you will find the following features:
- Data Storage (Relational)
- Cloud Code Functions
- APIs (GraphQL and REST)
- File Storage
- Authentication
- Push Notifications
5-minute quick start
After creating your Back4App account and your first App, go to your App Dashboard and get your App Keys under App Settings-> Security & Keys
(check the image below). Note that you will always need two keys to connect with Back4App, the Application ID
, and another key according to the SDK
you will use.

Parse JavaScript SDK
can be used in a large amount of platforms and frameworks.
1. Install Parse SDK
$ npm install parse @react-native-async-storage/async-storage --save
Use CocoaPods to add the native RNAsyncStorage to your project:
cd ios & pod-install
2. Initialize the SDK using your Application ID and JavaScript Key

// if defined
.clientKey(getString(R.string.back4app_client_key))
.server(getString(R.string.back4app_server_url))
.build()
);
Don’t forget to define this file in the
AndroidManifest.xml
. To do so, go to theAndroidManifest.xml
file and add the following line of code inside theapplication
tag:
1 android:name=".App"If the name of the java file that extends Application that you created on the previous step isn’t “App”, don’t forget that the code above should have the correct name of the file (
android:name=".name_of_the_file"
).
