API-First development: What & Why

Image from “How API-First Development Boosts Productivity”full story - http://goo.gl/o3WBIq

What:every piece of shared functionality for your organization it should be exposed as a RESTful HTTP API to all of your other developers

Why:● Enforcing separation of

concerns;● Hiding complexity

“API Economy” is coming

http://goo.gl/o3WBIq

Pretty old & well-deserved Horse...

Google App Engine: easy to build, scale, maintain

● Java, Python, PHP, Go Support

● Rapid application development

● Scale infinitely

● Replicated data storage

● Versioning and Traffic Splitting

● Familiar development tools

… but with the new carriage

Google Cloud Endpoints

Extremely simple way to expose server side logic on full power, management free Google App Engine platform

• Uses App Engine’s auto-scaling and high-availability

• Exposes standards based REST interfaces with built-in authorization

• Auto-generates strongly typed, mobile optimized client libraries for Android, iOS and web.

• Makes you more productive!

Taking the plumbing out of API programming

Mobile Backend Running on Google App Engine Instances



Cloud Endpoints

Clients

Android Studio + Cloud Endpoints

Easiest way for mobile developers to connect to Google Cloud Platform

• Create Google App Engine backends in Android Studio

• Generate Java-specific bindings for use in Android app

• Benefit from as-you-type validations and quick-fixes when defining the backend API

• Use App Engine-specific Gradle tooling that allows for a unified client/backend build

Call Cloud Endpoints API from iOS

● Generate RPC Discovery documents in AndroidStudio using

appengineEndpointsGetDiscoveryDocs Gradle task

● Download and build ServiceGenerator

● Use ServiceGenerator command line utility to generate Objective-C code from

RPC Discovery document

● Include generated Objective-C files to your XCode project

● Add code to call Cloud Endpoints API from the UI of the app

https://developers.google.com/appengine/docs/java/endpoints/consume_ios#Java_Compiling_the_client_library_generator_and_generating_your_library

http://goo.gl/JhdaVW

Call Cloud Endpoints API from Javascript

• Use the Google Javascript Client Library

<script src="https://apis.google.com/js/client.js?onload=init"></script>

• Load the endpoint

var ROOT = 'https://your_app_id.appspot.com/_ah/api';

gapi.client.load('your_api_name', 'v1', function() { doSomethingAfterLoading();}, ROOT);

• Use the endpoint:gapi.client.tictactoe.scores.insert({'outcome':

'WON'}).execute(function(resp) {

console.log(resp);

});

API-first is cool but...

● we do not have dedicated

backend developers;

● we want to prototype quickly;

● we just need to store the data

and sync them between the

connected clients;

● we need offline support;

Firebase

“Over the past three years, we’ve gone from a crazy idea that ‘just might work’ to a proven product used by 110,000 developers. Today, I couldn’t be happier to announce that we’ve joined Google.”

https://www.firebase.com/blog/2014-10-21-firebase-joins-google.html


Firebase

● Server and NoSQL database to interact with through API calls

● Sync data from multiple applications● Simple Login Service with several

types of built-in authentication● Security: SSL encryption & security

rules● Support offline mode


Firebase Forge

The Firebase Forge provides a convenient GUI for visualizing and manipulating your data in real-time.
