This document provides an overview of the Parse platform and its capabilities for building mobile and web applications. It describes Parse Core which allows storing and querying data in the cloud. It also covers user authentication, social integration, push notifications, cloud code, and analytics tracking. The document shows how to perform common tasks like saving and querying objects, user signup/login, and sending push notifications. It emphasizes that Parse provides a full backend as a service to focus on app business logic and UI rather than operations.

- 11. ParseQuery<ParseObject> query = ParseQuery.getQuery(”Talk”); query.findInBackground(new FindCallback<ParseObject>(){! public void done(List<ParseObject> talkList, ParseException e) {! if (e == null) {! // We have a list of all the Basic track talks! } else {! // Something went wrong; check the ParseException! }! } } // Find only the talks that are in the Basic track! query.whereEqualTo(”track”,”basic”); Getting a List of Objects
- 12. byte[] data = myPhotoObject.toByteArray(); ParseFile image = new ParseFile(”Parse-2.jpg”, data);! image.saveInBackground(); ParseObject picture = new ParseObject(”Picture”);! picture.put(“title”, “Red Hot Chili Peppers concert”);! picture.put(“image”, image);! picture.saveInBackground(); Saving Files
- 13. Easy User Management Parse Social •ParseUsers make it simple to: • Sign up • Log in • Manage user session with “currentUser” • Create Roles in your app • Improve app security with ACLs • Integrate with Facebook and Twitter
- 14. ParseUser.logInInBackground( “janedoe”, ! “mypassword123”, new LogInCallback() {! public void done(ParseUser user, ParseException e) {! if (user != null) {! // The user is logged in! } else {! // Something went wrong; check the ParseException! }! }! }); Sign up Log in ParseUser ParseUser user = new ParseUser();! user.setUsername(“janedoe”);! user.setPassword(“mypassword123”);! user.setEmail(“janedoe@fb.com”);! user.signUpInBackground();

- 16. •Background Jobs •For long running jobs •Can be scheduled Run custom app code in the Parse Cloud Cloud Code •Running Code when Objects are Saved or Deleted •Cloud functions & custom webhooks
- 17. A Simple Background Job Parse.Cloud.job(“userMigration”, function (request, status) {! // Set up to modify user data Parse.Cloud.useMasterKey();! // Query for all users! var query = new Parse.Query(Parse.User);! query.each(function(user) {! // Set and save the change! user.set(“plan”, request.params.plan);! return user.save(); }).then(function() {! // Set the job’s success status! status.success(“Migration completed successfully.”); }, function(error) { // Set the job’s error status status.error(“Uh oh, something went wrong.”); }); });
- 19. Integrate with virtually any third-party service •Parse Image Module • Resize, crop, scale • Change image format •User Session Module • For server-side apps • Manage user session across pages Cloud Modules •Send text messages, emails, or accept payments •Connect to services with Parse.Cloud.httpRequest
- 23. Parse Push
- 24. ParseInstallation.getCurrentInstallation().saveInBackground(); • Pushes are sent to Installations •1 device + 1 install of your app = 1 Installation • Add relationships to objects of interest, e.g. current User Push Notifications Installations
- 25. ParsePush push = new ParsePush();! push.setChannel(“Giants”);! push.setMessage(“The game starts in 5!”);! push.sendInBackground(); Push to a Channel Subscribe users by interest or category
- 26. Find users who match particular criteria Push to a Query ParseQuery pushQuery = ParseInstallation.getQuery();! pushQuery.whereEqualTo(“isFacebookEmployee”, true);! ! ! ParsePush push = new ParsePush();! push.setQuery(pushQuery);! push.setMessage(“Good afternoon, Facebook!”);! push.sendInBackground();
- 28. Parse Analytics
- 29. Parse Analytics Measure App Usage • API calls • App open rates • Push campaigns • Custom events Track Any Data Point In Real Time
- 31. event: "signedUp"! dimensions: {! gender: "f",! source: "web",! friendsUsingApp: "35",! wasReferred: "true"! } • Note: •Each event can have a maximum of 4 dimensions •Dimensions must be strings Dive Deeper: Custom Analytics •Save a free-form event with dimensions for segmenting results
