security with ACLsManage user session with “currentUser”

Create Roles Log in & add 3rd party auth


SIGN UP A PERSON


SIGN UP A PERSONParseUser user = new ParseUser();user.setUsername(”janedoe”);user.setPassword(”mypass123”);user.setEmail(”[email protected]”);user.signUpInBackground();


LOG A PERSON IN


LOG A PERSON INParseUser.logInInBackground( ”janedoe”,

CLOUD CODE

Run custom app code in Parse’s cloud

Run code when objects are saved or deleted

Create custom functions and web hooks

Schedule long-running jobs with Background Jobs

CLOUD MODULES

Easy third-party integration with pre-built modules

Send email Take payments Add SMS to your

app Connect with any RESTful service

using Parse.Cloud.httpRequest

BACKGROUND JOBS

Schedule long-running jobs

For operations that need to be performed regularly

or on command

Longer timeouts— 15 minutes

Trigger from the web UI or REST endpoint

A SIMPLE JOB


A SIMPLE JOBParse.Cloud.job(”lowercaseallthethings”, function (request, status) {

// Set up to modify user dataParse.Cloud.useMasterKey();

// Query for all usersvar query = new Parse.Query(Parse.User);query.each(function(user) {

// Set and save the changeuser.set(”name”, user.name.toLowerCase());return user.save();

}).then(function() {// Set the job’s success and error statuses

status.success(”All users now have lowercase names”);}, function(error) {

status.error(”Job did not complete.”);});

}

Parse Local Datastore


Parse.enableLocalDatastore();

ParseQuery<ParseObject> query = ParseQuery.getQuery(“GameScore");query.orderByDescending(“score”);query.fromLocalDatastore();query.findInBackground(new FindCallback<ParseObject>() { ...});


Parse Config

Create and manage configuration variables for your apps from the Parse Dashboard

PARSE PUSH

1 device + 1 install of your app = 1 Installation

Pushes are sent to Installations

ParseInstallation.getCurrentInstallation().saveInBackground();

INSTALLATIONS

Add relationships to objects of interest, e.g. users

Channels vs Queries

Target stable interest groups with channels

PUSH TARGETING

Send pushes to ad-hoc or changing groups by pushing to queries

To push to a query, your Installation class must point

to the class of interest


PUSH TO A CHANNEL


PUSH TO A CHANNELParsePush push = new ParsePush();push.setChannel(”PSGFans”);push.setMessage(”The game starts now on channel 5!”);push.sendInBackground();


PUSH TO A QUERY


PUSH TO A QUERYParseQuery pushQuery = ParseInstallation.getQuery();pushQuery.whereEqualTo(”hasCheckedInToVenue”, true);

ParsePush push = new ParsePush();push.setQuery(pushQuery);push.setMessage(”The keynote is about to start!”);push.sendInBackground();

PARSE ANALYTICS

Measure App Usage

API calls

PARSE ANALYTICS

Burst rates Responses to push notifications

Events + Dimensions

Create your own events and track custom user

behaviour

CUSTOM EVENTS

Slice and dice your data however you choose

Save additional parameters with

dimensions

CUSTOM EVENTS

event: "signedUp"dimensions: {gender: "f",source: "web",friendsUsingApp: "35",wasReferred: "true"

}

CUSTOM EVENTS


CUSTOM EVENTS


CUSTOM EVENTSMap<String, String> dimensions = new HashMap<String, String>();

// Add key-value pairs to be saved alongside eventdimensions.put(”gender”,”f”);dimensions.put(”source”,”web”);// Consider using buckets to meaningfully segment eventsdimensions.put(”friendsUsingApp”,”25-50”);dimensions.put(”wasReferred”,”true”);

ParseAnalytics.trackEvent(”signup”, dimensions);

Knowledge is Power

Is the first level of my game too hard?

CUSTOM EVENTS

Why aren’t people completing purchases

in my app?

How successful was our last push campaign?
