Track: JavaScript: Powering the Modern Web

Location: Churchill, G flr.

Day of week: Wednesday

Explore the frameworks that make JavaScript so popular, and learn how JavaScript-based languages are evolutionising frontend (and backend) development.

Track Host: Richard Rodger

State Management for React Using Context and Hooks

Redux is one of the most popular approchaes to state management in React applications. However, it comes with a decent amount of boilerplate plus it often ends up being used everywhere, no matter the context or app size. This talk explores a barebones alternative approach to state management that is suitable for small/medium apps as well as define the pros and cons when compared to Redux. We will live code relying on the latest versions of context and hooks React APIs. Don’t miss if you want to see how much simpler managing state can become.

A New Way to Profile Node.js

It’s been weeks and the organization you work for seems to be slowly turning against you. At least that’s what it feels like. User experience is poor because of slow API’s, sales are being missed, performance-linked SEO heuristics are causing a drop in page ranking. Mobile users have all but given up. Operations have reported that a critical Node.js service owned by your team is spinning at 70-100% CPU, and all parts of the application dependent on the service are experiencing intermittent slowdowns or in some cases, complete unavailability. What are you going to do now?


In this talk we’ll present a new and straightforward way to identify bottlenecks in Node.js and beyond.

Bringing JAMStack to the Enterprise

As application development trends toward smarter devices our server strategy is beginning to see a shift as well. Application servers written in node.js are beginning to thin out as more and more logic lives directly on content delivery networks and individual devices.


This past year my team at PayPal began looking at how we could radically improve our developer experience and deliver high quality applications faster. We landed on the JAMStack model, which stands for "JavaScript, APIs and Markup". This approach emphasizes web apps powered by static assets living on content delivery networks.


This talk will walk you through some of the challenges we faced with our node.js application servers and why we think the JAMStack approach will improve performance for both our apps and our developers. We’ll include discussions around performance, security, development experience and deploy speed. This talk will be relevant for those curious about graphql, gatsbyJS and JAMStack generally as well as those interested in speeding up the development and deploy process for their teams.

Jamund Ferguson, Web Platform Team Lead @PayPal

Build Node.js APIs using Serverless

Serverless lets you focus on coding and testing instead of provisioning infrastructure, configuring web servers, debugging your configuration, managing security settings, and all the drudgery normally associated with getting an app up and running. In this session with, you’ll discover how to migrate an API of an existing app to Azure Functions. You’ll learn how to use Visual Studio Code and the Azure Functions extension to speed up your work. After this session, you’ll join the ranks of serverless developers.

Programming the Cloud with TypeScript

JavaScript has been applied to a wide variety of domains over the last few decades - from web to server and IoT to serverless.  One domain that has resisted this trend is Cloud Infrastructure, which is still largely managed by copy/pasting YAML files or pointing and clicking in web consoles.  A new breed of solutions is showing how real programming languages like JavaScript and TypeScript can be used to bring the many benefits of these languages for enabling more robust software engineering to our increasingly complex and critical cloud infrastructure.  In this talk, Luke Hoban will review the unique benefits of applying programming languages in general, and TypeScript in particular, to the cloud infrastructure domain - highlight a few of the projects that are leading the industry shift in this direction - and show examples of using TypeScript and Pulumi to build everything from serverless applications on AWS to Kubernetes applications on Google Cloud.
