The Composite App

The Client Problem

Problem: Old Custom UI Technology  Server-side generated, page based HTML

HTML <div>...</div>

New UI: Component-based Client-rendered

JSON component:{...}

<div>...</div>

Aura and Lightning Component Framework

Lightning Component Framework

Lightning Component Design Principles

•  Component author namespacing

•  Automatic component-based CSS namespacing

•  Everything is a component

•  Allow for programmatic or point-and-click UI composition

•  Enable Salesforce, customers, and partners to build composite UIs

•  Works on any form factor

Many Components Many Server Trips

Salesforce1 Enterprise APIs  The Salesforce “Data” APIs

•  Allow programmatic access to your salesforce data through various API technologies

•  Many different APIs to suit your specific needs

Rest APIs

Access and manipulate data with a RESTful pattern with JSON and XML payloads

Soap APIs

Access and manipulate data using SOAP.

Streaming APIs

Subscribe to updates using a Bayeux / CometD HTTP Streaming API.

Bulk APIs

Perform Bulk Queries and Inserts/Updates Asynchronously.

Boxcarring, what a great idea!

 Boxcarring is dependent on Lightning Components

 Only works with one client interface

 What about all those API apps out there?

 If only we could let any client batch together requests…

Many Requests Many Server Trips

POST Record

GET Server Gen Data

GET API Limits

Composite Batch REST API

.../composite/batch POST Batch

{ "batchRequests":[ {POST}, {GET}, {GET} ] }

Sample Batch Request  POST: <salesforcedomain>/services/data/v35.0/composite/batch

 {"batchRequests" : [   {"method" : "POST",   "url" : "v35.0/sobjects/account/",   "richInput" : {"Name" : "NewName", "Industry" : "Tech"}},   {"method" : "GET",   "url" : "v35.0/sobjects/account/describe/"},   {"method" : "GET",   "url" : "v35.0/query?q=select id, name, industry from account

 order by createddate desc limit 10"   }]  }

Parent/Child Related Data

POST Account

POST related Contacts

POST related Cases

RESP: Account ID

RESP: Contact IDs

RESP: Case IDs

Composite Tree REST API

.../composite/tree/entity

POST Tree

”records":[ {parent1}, {parent2}, {parent3} ]

Sample Batch Request  POST: <salesforcedomain>/services/data/v35.0/composite/tree/Account

 {"records" :[   {"attributes": {"type":"Account", "referenceId":"ref1"},   "name" : "SampleAccount", "phone" : "1234567890",   "type" : "Analyst", "industry" : "Banking",   "Contacts" : {   "records" : [   {"attributes": {"type":"Contact", "referenceId":"ref2"},   "lastname" : "Smith", "title" : "President"},   ...]},   "Cases" : {   "records" : [   {"attributes": {"type":"Case", "referenceId":"ref3"},   "" : "", "" : "", "" : ""}   ...]}, }}, ...] }
