Realtime, feature-rich apps are here
Building those apps is hard
Firebase
A powerful platform for
building extraordinary apps
Firebase Is Your Backend
Realtime Database
NoSQL JSON data store
Cross-platform client-side SDKs
Offline out-of-the-box
Auto-scaling
RESTful API
Realtime
Whenever data is updated in Firebase,
it sends the update down to every
listening client
Cross-platform
Storing Data
{
"location": {
"city": "Chicago",
"state": "Illinois",
"country": "USA"
}
}
Storing Data (Obj-C)
Firebase *ref = [[Firebase alloc] initWithUrl:@"https://1871.firebaseio.com"];
Firebase *locationRef = [ref childByAppendingPath: @"location"];
NSDictionary *location = @{
@"city" : @"Chicago",
@"state": @"Illinois",
@"country": @"USA",
};
[locationRef setValue: location];
Storing Data (Swift)
var ref = Firebase(url: "https://1871.firebaseio.com")
var locationRef = ref.childByAppendingPath("location")
var location = [
"city": "Chicago",
"state": "Illinois",
"country": "USA"
]
locationRef.setValue(location)
Storing Data (Java)
Firebase ref = new Firebase("https://1871.firebaseio.com");
Firebase locationRef = ref.child("location")
Map<String, String> locationMap = new HashMap<String, String>();
locationMap.put("city", "Chicago");
locationMap.put("state", "Illinois");
locationMap.put("country", "USA");
locationRef.setValue(location);
Reading Data
{
"location": {
"city": "Chicago",
"state": "Illinois",
"country": "USA"
}
}
Reading Data (Obj-C)
Firebase *ref = [[Firebase alloc] initWithUrl:@"https://1871.firebaseio.com"];
Firebase *locationRef = [ref childByAppendingPath: @"location"];
[locationRef observeEventType:FEventTypeValue withBlock:^(FDataSnapshot *snapshot) {
NSLog(@"%@", snapshot.value[@"city"]); // "Chicago"
} withCancelBlock:^(NSError *error) {
NSLog(@"%@", error.description);
}];
Reading Data (Swift)
var ref = Firebase(url: "https://1871.firebaseio.com")
var locationRef = ref.childByAppendingPath("location")
locationRef.observeEventType(.ChildAdded, withBlock: { snapshot in
println(snapshot.value.objectForKey("city")) // "Chicago"
}, withCancelBlock: { error in
println(error.description)
})
Reading Data (Java)
Firebase ref = new Firebase("https://1871.firebaseio.com");
Firebase locationRef = ref.child("location")
locationRef.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot snapshot) {
HashMap<String, String> location = snapshot.getValue();
System.out.println(location.get("city")); // "Chicago"
}
@Override
public void onCancelled(FirebaseError firebaseError) {
System.out.println("The read failed: " + firebaseError.getMessage());
}
});
Authentication
No server required
Anonymous
Email / password
Facebook, Twitter, Google, etc.
Custom
Authenticating Users (Obj-C)
Firebase *ref = [[Firebase alloc] initWithUrl:@"https://1871.firebaseio.com"];
[ref authUser:@"mcdonald@firebase.com" password:@"password"
withCompletionBlock:^(NSError *error, FAuthData *authData) {
if (error) {
// There was an error logging in to this account
} else {
// We are now logged in
}
}];
Authenticating Users (Swift)
let ref = Firebase(url: "https://1871.firebaseio.com")
ref.authUser("mcdonald@firebase.com", password: "password",
withCompletionBlock: { error, authData in
if error != nil {
// There was an error logging in to this account
} else {
// We are now logged in
}
})
Authenticating Users (Java)
Firebase ref = new Firebase("https://1871.firebaseio.com");
ref.authWithPassword("mcdonald@firebase.com", "password", new Firebase.AuthResultHandler() {
@Override
public void onAuthenticated(AuthData authData) {
// We are now logged in
}
@Override
public void onAuthenticationError(FirebaseError firebaseError) {
// There was an error logging in to this account
}
});
