<div><div>For many years, we have migrated all our devtools to Node.js for the sake of simplicity: a common language (JS/TS), a large ecosystem (NPM), and a powerful engine. In the meantime, we moved a lot of computation tasks to the client-side thanks to PWA and JavaScript Hegemony. So we made Webapps for years, developing with awesome reactive frameworks and bundling a lot of dependencies. We progressively moved from our simplicity to complex apps toolchains. We've become the new Java-like ecosystem. It sucks. It's 2021, we've got a lot of new technologies to sustain our Users eXperience. It's time to have a break and rethink our tools rather than going faster and faster in the same direction. It's time to redesign the Developer eXperience. It's time for a bundle-free dev environment. It's time to embrace a new frontend building philosophy, still with our lovely JavaScript.

Hi everyone! I'm Rohit, a founding engineer at Tria. We are working on bringing the world to Web3 using names. My talk is about gaining performance and taking runtime to build time. There is an upward trend in libraries towards build time optimization, especially in React. Build time optimization improves performance, reduces bundle size, and provides more predictable software. Babel is a free and open source JavaScript transpiler that allows leveraging latest JavaScript features and moving computationally heavy logic from runtime to build time. Building a Babel plugin involves checking for a style prop inside an HTML tag and searching for aliases or token values. The visitor pattern is used to define the JSX type of node and access its path and attributes. The plugin can be customized for different utilities by defining aliases and tokens in a config file. Helpful resources for understanding and building custom Babel plugins include the Babel handbook, Babel docs, astexplorer.net, and the speaker's Twitter account.

We'll be discussing mainly the industry shift towards build time and why you'll be lacking behind if you don't learn about the intricacies of build time optimizations and modern architectures, and how you can leverage this new trending architecture to boost your product's performance many times.

Today's Talk is about porting to Rust, specifically the experience of porting Turbo Repo, a build system for JavaScript, from Go to Rust. The speaker discusses the challenges faced during the porting process, such as file permission code discrepancies and issues with Alpine Linux. They explain the approach taken, including using a Rust shim and porting individual Go dependencies to Rust. The Talk also covers the limitations and challenges encountered during the porting process, as well as the benefits of leveraging the Rust ecosystem. The speaker discusses the considerations of rewriting versus porting and the importance of institutional knowledge. They also touch on the performance impact of the porting process and the improvements achieved by moving to a fully Rust implementation.

Everybody loves talking about Rewriting in Rust, but rewrites are hard. It’s far too easy to fall into second system effect, shipping delays, and end up losing all your users. How can you move to Rust while still shipping features and keeping your users happy? Easy, instead of rewriting, port! In this talk, we’ll go over how we ported Turborepo from Go to Rust using three different strategies: a Rust shim that wrapped the existing Go code; a Rust-Go-Rust sandwich to incrementally port dependencies; and finally a completely parallel Rust implementation. We’ll talk about why we chose these strategies, how we went about implementing them, and how we shipped them to users.

JavaScript is widely used in web, mobile, and backend development, and now it is also being used to create TV apps. TVs with web-based operating systems can be targeted with JavaScript applications, and React is commonly used for TV app development. React Native allows for cross-platform TV app development, except for Roku. User interactions and focus management are important considerations in TV app development. Performance optimization is crucial for TV apps, as TVs have lower device scores and limited RAM. Spatial virtualization can significantly improve TV app performance.

The ever-expanding landscape of JavaScript applications has now reached the big screen - yes, you heard it right, you can build TV apps with JavaScript!  The TV operating space is a mess; there’s more fragmentation than the Android ecosystem, and that’s saying something. Each manufacturer has tried to reinvent the wheel by making their own OS. At the moment, the main players are Android TV, tvOS, WebOS, Tizen, among a whole myriad of others.  This makes it a unique place where Javascript and web technologies can become a uniting factor and save you from the stress of trying to develop and maintain handfuls of apps for the big screen.  We’ll talk about how to build TV apps, what JS frameworks can help in this, and explore the challenges that come hand-in-hand with TV app development, namely performance bottlenecks and focus management using remote controls.

This Talk explores the paradigm of message queues for reliable backend execution. It highlights the benefits of message queues, such as guaranteed delivery and offloading of long-running processes. The drawbacks of using queues are discussed, including the complexity of managing infrastructure and applications. The solution of using a reliability layer called Ingest is presented, which allows for non-blocking background tasks and provides a dashboard for monitoring and managing jobs. The Talk also emphasizes the importance of reliability in building software systems and introduces the expanding scope and functionality of Ingest.

Building Reliable Backends with Durable Execution

Sylwia Vargas

Microfrontends is an architecture used by big companies to split monolithic frontend applications into manageable parts. Maintaining a consistent look and feel across different microfrontends is a challenge. Sharing styles can be done through Vanilla CSS, CSS modules, or CSS in JS. JavaScript variables can be used in styles, but readability and runtime overhead are considerations. Sharing state in microfrontends can be achieved through custom events, broadcast channels, shared state managers, or custom PubSub implementations. Module federation with Vite allows for client composition and sharing dependencies. Configuration is similar to Webpack, and future work includes working on the QUIC framework.

From my experience one of the hardest things is to share information between microfrontends, so in this talk I would like to explain various ways on how to share a design system to ensure uniformity to the application. Another difficult thing is sharing dependencies, fortunately with module federation it can be done, but how can I use different versions of the same library and how does it work behind the scenes? I'm the creator of module-federation/vite library, with React and this library, I'd like to show you how you can achieve these results by configuring everything correctly.

This Talk discusses module system complexities and terminology, TypeScript and Node disagreements, and fixing TypeScript errors with the Helmet package. It also explores module resolution and type disagreements, challenges with TypeScript and Node support, and the need for improvements in popular packages.

Have you ever installed a dependency, imported it just like the README instructs, and immediately been met with strange TypeScript errors about default imports, the output module format, or ESM/CommonJS interoperability? When everything works at runtime but TypeScript complains, you might wonder, is this a TypeScript bug? Or… are the types wrong? The JavaScript module and package publishing landscape is complicated. Nearly one third of the most popular types-included npm packages have some sort of module-related typings issue that can cause confusion for users. But things are starting to improve. In this talk, we’ll: - explore how we got here—why are things complicated? - develop a simple and accurate mental model for how TypeScript sees packages - see how the `arethetypeswrong` tool can help catch issues before publishing - look at trends in the `arethetypeswrong` data for popular packages over time - discuss next steps for making the typed package ecosystem better

Are the (module) types wrong?

[♪ music ♪ by The Illuminati plays)] I see a common thread across any project I work on. Different developers are making the same mistake and we have preferred ways of doing things. Preventing mistakes and sharing best practices are great reasons to look at tools like linters and in particular ESLint. Let's write our first rule together. We're just scratching the surface of building our own tools, which can have a massive impact on improving the developer experience.

Your first JavaScript tool might not be the next Babel or ESLint, but it can be built on them! Let's demystify the secret art of JavaScript tools, how they work, and how to build our own. We'll discover the opportunities in our everyday work to apply these techniques, writing our own ESLint rules to prevent mistakes and code transforms to make breaking changes easy to apply. We’ll walk through the fundamentals of working with an abstract syntax tree, and develop our understanding through a live-code. You will be amazed at what you can build, and together we’ll explore how to get started.

React docs suggest using production-grade frameworks like Remix, Next.js, or Gatsby. But if you want to start with a simple pure React app, you can use Vite or Parcel as generic bundlers. Nx provides facilities to set up a workspace similar to Create React app with modern features. You can modularize and scale your project using Nx libraries. Consider upgrading to a Monorepo structure and adding Next.js or Remix applications. Migration strategies are available for existing React apps.

So CRA is no more and it probably was about time. The React docs suggest Next, Remix or Gatsby...but you're not ready yet for a full-blown React Meta-Framework and really just want pure React. Any alternatives? In this talk, I'm going to explore exactly that. We've got 7 minutes, so no slides, just code where we're going to set up a new React standalone application using Nx.

Babel macros allow for code transformation without multiple plugins, providing a solution to the downsides of regular Babel plugins. Understanding AST is crucial for developers working with transpilers, and exploring its structure and representations can help derive code. Babel started as a transpiler but has evolved into a tool for live code transformation. Babel macros are supported in various React-based frameworks and can be used for track translation and CSS to React Native macros. However, macros have limitations, such as being synchronous and evaluated at compile time.

The talk will cover all the possibilities Babel Macro opens up and also gives an overview of Abstract Syntax Tree. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
