DESIGNING MODULES FOR THE BROWSER AND NODE

JSCONF 2014

HI. I’M KEVIN.developer evangelist @ twilio

MAKE AND RECEIVE PHONE CALLS

SEND AND RECEIVE TEXT AND PICTURE MESSAGES

ENABLE VOIP CALLING IN DESKTOP BROWSERS OR MOBILE APPS

NPM INSTALL TWILIO

WHY BROWSERIFY?

• Same module loading system

• Same package manager

• Same code style

• Potential for code reuse

• Many modules just work

DO I NEED TO BROWSERIFY?

Maybe, if your module:

• Has complimentary interfaces on client and server (ws)

• Doesn’t just work with Browserify’s shims

DESIGN TO BE BROWSERIFIED

• Expose a browser-specific entry point

• Define any custom shims for dependencies as needed

• Setup source transforms

DEMO

USE CASE - TWILIO CLIENT (VOIP)

• Enable VoIP calling between browsers, mobile apps, and standard PSTN phones

• Requires both a server and client component

• Lots of configuration when client and server are disconnected

USE CASE - TWILIO CLIENT (VOIP)

BROWSER NODE

Request capability token

USE CASE - TWILIO CLIENT (VOIP)

BROWSER NODE

Hit Twilio REST API maybe, return capability token

USE CASE - TWILIO CLIENT (VOIP)

BROWSER TWILIO
