7:35 pm

Live-coding demo - Build your own backend in the `redux` style with GraphQL mutations (dispatch), `pure` serverless functions (reducers), and GraphQL subscriptions (updated state)

What if it was possible to build backend features for our react apps in the same way that we use redux in our react apps? In this live-coding demo, I will show you how we’ll add backend business logic using the redux abstractions of dispatching actions, writing reducers as pure functions and subscribing to updated state. Our backend will be completely serverless and using open-source and managed services so that we’re not actually deploying and maintaining any servers. We will use GraphQL mutations from our react app to dispatch actions. These will trigger serverless functions which are pure and return the modified state, which will be persisted safely on a cloud managed database. Portions of your app that are subscribed to the state using GraphQL subscriptions (live-queries) will automatically update! You will witness the raw awesomeness of being able to use javascript and graphql in a pattern that you are comfortable with to build backend features from scratch.

Topic Tables | Various

Topics include GraphQL, Web Assembly, Typescript, React Hooks, D3, A11Y and Accessibility, ReasonML, Redux, Serverless, and more!

7:45 pm

Learn something new from the managed topic tables

Keynote pt. 1 - The State of the React Ecosystem

React has exploded in popularity. But it’s only a UI library, not a full-fledged framework like Angular, Ember or [insert latest JS framework]. We need to create our own “framework” by picking from the plethora of libraries in the React ecosystem. But which ones should we choose? Or better yet, which ones do we actually need? Do we still need Redux? What about handling styling, testing and routing, etc? How does it all come together?!!?! Let’s walk through the tools and helper libraries that surround React. By the end of the session, you’ll have a solid understanding of the ecosystem and know which libraries you should prioritize learning first in order to confidently build your own React-based stack.

Keynote pt. 2 - The State of Redux

Not only is there a lot going on with React, there’s a lot happening with Redux too. This talk will help you catch up with the latest news and updates around Redux, including – How Redux relates to to technologies like the React hooks and context APIs, or Apollo Client and GraphQL, progress on new versions of React-Redux that can take advantage of the latest React capabilities, the new Redux Starter Kit package and how it can simplify your Redux apps, and improvements to the Redux documentation, among others.

11:45 am

Reactive Data on the Full Stack

React puts our views on the screen, but where does our data come from? We often have a database in the back-end, but how do we stay up to date as data changes? How can we make sure that computed values and aggregations are cached efficiently? How does all of this work with a client-side cache, and offline functionality? This talk will open our eyes to the complexities in this space, and will introduce some general patterns that we can use to easily build realtime and offline-friendly applications.

1:00 pm

Building Design Systems in React

Design systems are everywhere in 2019. It might be tempting to whip up a component library, say it’s your “design system” and call it a day - but careful consideration must be taken to make sure that what you build is flexible, sustainable and maintainable. In fact, design systems can’t just be a React component library on its own. This talk will cover the who, what & why of design systems as well as our approach building a React component library to accompany GitHub’s design system, Primer. Attendees will walk away with a deeper knowledge of how to design a public API for components, how theming works, and common pitfalls one might come across when trying to scale a design system across an organization.

Transform for Good -- Using Babel Macros

Babel plugins are a powerful tool we use daily to transform and modify our code helping us create great projects faster. They can take entire mundane and repetitive code blocks and abstract them away, making the process faster and more enjoyable. But once we’ve made a plugin, if we’ve gotten that far, the set-up then config can be daunting. Enter Babel-plugin-macros. This allows us to do project-wide code transforms will all the benefits of a plugin, but with zero config. And we all love zero config.

1:50 pm

Type-safe forms in React

Using controlled components to write simple input forms in React is a breeze, but as forms become more complex and validations are added, it is difficult to write robust code while maintaining a good user experience. This talk discusses the challenges with large and complex forms, and how we’ve taken them on at Flexport, where forms form the core of our business.

We're gunna program like it's 1999

The mental model for building for the web largely hasn’t changed in the last 20 years, but we’ve incorporated complexity, richness, grown our community a thousand fold, and scaled to billions. This year the web turns 30, and we look back at the steady march forward of better abstractions, better syntax, and better mental models that brought us here.
