Scalability is the ability of a system, network, or application to handle a growing amount of work in a capable manner or its ability to be enlarged to accommodate that growth. In terms of JavaScript, scalability refers to the ability to quickly and efficiently increase the size and complexity of a website or web application without sacrificing performance or usability. This includes the ability to add more nodes (computers) to a distributed system, as well as the ability to easily add more features and capabilities to an existing system.

Building a Web-App: The Easy Path and the Performant Path. Why Are They Not the Same?
We use frameworks to make building our applications easier. Yet as the application scales, its performance suffers. There is no one thing, but rather a death by thousand cuts. Developers are under pressure, and they often choose the easy and quick path to deliver a feature rather than the performant path. The performant path is usually more work. So let's look at these two paths and imagine a world where the performant path is the quick and easy path.

Road to Zero Lint Failures: Tackling Code Quality Challenges at Scale
Lint rules enable us to uphold code quality and minimize errors. It can positively impact developer productivity and happiness especially when working in a massive application with multiple teams working together. But what if your large scale application contains thousands of lint failures over the many years it has been running in production? This talk will explore actionable strategies for effectively addressing lint failures at scale so that we can once again rely on lint rules to ensure consistent code quality and streamline development processes, leading to a more robust and maintainable codebase.

Scaling React-Three-Fiber Applications beyond the Hello World
A lot of recent talks at other conferences have talked about how to start using React and THREE.js to create 3D experiences on the web. In my career I've built several complex applications using those technologies, including a big Figma-like 3D editor, and I've learnt a lot of patterns and tricks on how to make it actually fast and scalable. Unfortunately, though, nobody is also talking about those tricks an what it really takes to build an rendering engine similar to the one that Figma uses.
My goal with this talk is to give people an overview of the challenges that may arise when you try scaling your application, and what are some lesser known tricks to overcome them: instancing, memory usage reduction techniques, SDF-based text rendering, GPGPU and tree data structures. Everything of course done with Javascript, React and THREE.js.

Zod === Typescript, but at Runtime in Your React Applications
In this talk, I want to show how we can use Zod to guarantee the type in a React Application at runtime. Environment variables, HTTP requests, forms and so on could create troubles in our applications, mainly if they contain unexpected types. Using Zod, we can create schemas to guarantee the types expected in our editor at runtime. In this way, we can react quickly when an environment variable misses or when someone changes the API contract without informing us.
A small validation layer in our applications can prevent a bad user experience and notify us immediately, so we can fix the problem as soon as possible and mitigate the visualization of wrong data.

Handling Data at Scale for React Developers
It is very difficult to scale modern web applications to millions of concurrent users. Oftentimes, we've got to provision and consider in-memory Key/Value stores, search engines, analytics engines, and databases, all while preserving traceability through the layers. This talk expands on the technical details of web apps at this scale, and offers a simpler way to achieve the same effect without the technical hassle.

How to Edge Cache GraphQL APIs
For years, not being able to cache GraphQL was considered one of its main downsides compared to RESTful APIs. Not anymore. GraphCDN makes it possible to cache almost any GraphQL API at the edge, and not only that but our cache is even smarter than any RESTful cache could ever be. Let's dive deep into the inner workings of GraphCDN to figure out how exactly we make this happen.

Scalable React Development for Large Projects
Scaling React development across multiple teams can be incredibly difficult. Teams need to share core functionality while staying autonomous. Changes need to propagate through many projects while being tested. Nx is an open-source toolkit that allows organizations to scale development more easily than before! Nx makes setting up Cypress, Prettier, Storybook, Next.js, and Gats faster than ever. You can also develop full-stack using Node frameworks like Apollo and Nest.js and share code between frontend and backend. In this talk you’ll learn how large organizations like Facebook, Microsoft, and Google are able to successfully scale across multiple teams, business units, and products.

Going from Zero to Building Multi-Region GraphQL Applications
Off late GraphQL workloads see wide adoption in enterprise workloads as GraphQL provides a consistent and flexible way for UI to consume data from the APIs. For API developers like me, seeing GraphQL servers abstracting away the data filtering and the access patterns associated with backend APIs is a complete paradigm shift. Traditional API design tasks, like data modeling, access patterns required to implement high-performance Data APIs, are still relevant when implementing GraphQL applications?This talk will walk you through the learnings as a backend API developer building a hello world GraphQL application to implement a globally distributed GraphQL API for a real-world e-commerce application. We will look into scaling and resiliency required for building high-performance GraphQL APIs. Also, look into how database capabilities play an essential role in implementing a successful GraphQL application.

Platform-powered: Building a Frontend Platform to Scale as Fast as You Do 🚀
In 2019, our frontend engineers were asking hard questions about the future of our frontend build system. As new engineering teams continued to spin up new frontend microservices, our custom-built platform grew increasingly fragmented. This led to more headaches for our teams, who were struggling to keep up with maintenance patches and security updates. What could we do to get ourselves out of this mess?
Come join us as we discuss how we built a new platform with Next.js at its core to solve the challenges we faced. With the momentum of the Next.js community, we were able to extend this framework with a unique plugin architecture that allowed our engineers to hot-swap new packages and tools while allowing us to upgrade entire swaths of the stack at once. At the same time, we've multiplied the productivity (and happiness) of every frontend engineer at Lyft. We'll end with some great things to share that can be taken with you to address the challenges you face scaling your own frontend platforms!

Scaling Components Across Multiple Frameworks
React provides a great ecosystem for React developers, but challenges often arise for multi-team organizations who get to pick the technology of their choice. As teams and projects scale, and technologies change over time, being able to provide a universal component library as a design system for an entire organization proves to be difficult.
Stencil was created to help address this issue, most notably for Ionic, which is a UI library for mobile app development using web-technologies. In this talk we’ll walk through how Ionic is able to create an Ionic React library, using custom elements (web components) as the lowest level. Using the Stencil compiler, the Ionic team is able to generate various bindings for each of the frameworks, such as React, Angular, and Vue.
The benefit of this allows the design team to focus on maintaining one codebase, while the Stencil compiler does the heavy lifting to generate the various output targets. Additionally, end-users of each framework binding get to interact with their traditional component model they’re familiar with. React developers use @ionic/react no differently than any other React component, and the same goes for Angular and Vue.
