Node.js test runner is modern, fast, and doesn't require additional libraries, but understanding and using it well can be tricky.You will learn how to use Node.js test runner to its full potential.We'll show you how it compares to other tools, how to set it up, and how to run your tests effectively. During the workshop, we'll do exercises to help you get comfortable with filtering, using native assertions, running tests in parallel, using CLI, and more. We'll also talk about working with TypeScript, making custom reports, and code coverage.

Come and learn how you can supercharge your modern and secure applications using GraphQL and Javascript. In this workshop we will build a GraphQL API and we will demonstrate the benefits of the query language for APIs and what use cases that are fit for it. Basic Javascript knowledge required.

TypeScript has a powerful type system with all sorts of fancy features for representing wild and wacky JavaScript states. But the syntax to do so isn't always straightforward, and the error messages aren't always precise in telling you what's wrong. Let's dive into how many of TypeScript's more powerful features really work, what kinds of real-world problems they solve, and how to wrestle the type system into submission so you can write truly excellent TypeScript code.

This workshop enables you to learn how to develop React applications, and then deploy them to the cloud (or building them to the console) coupled with a backend, fully abstracted, with no complex backend configuration, simplifying the building and deployment of frontend & web apps to the cloud.

In this talk we uncover what Declarative Infrastructure means, and how it can work in TypeScript to naturally express higher-level distributed systems concepts (such as backend services, API calls, database queries, Pub/Sub messaging, caching and more), through the power of static analysis and code generation.The outcome is a fully reimagined DevOps process, with automatic infrastructure provisioning and built-in observability, that deploys straight to your own cloud.
Table of contents:- Introduction- Evolution of backend development, from servers to today's cloud-native world powered by DevOps and GitOps- What is Cloud Native, and how do we build modern backend applications? (Showing a microservices architecture powered by Express.js and Terraform)- What is Declarative Infrastructure? What does the space look like?- What problems does it solve compared to traditional DevOps practices?- How does it relate to Terraform/AWS CDK for infrastructure provisioning?- What are the downsides?- Building a Cloud Native backend with Declarative Infrastructure

We're all taught to follow the Testing Pyramid but the reality is that we build out the Testing Christmas Tree. In this workshop, David will talk you through how to break down projects and put the tests where they need to be. By the end of the workshop you will be able to update your projects so that anyone and everyone can start contributing and truly living up to "Quality is everyone job".
He will walk you through:- Component Testing- API Testing- Visual Regression Testing- A11Y testing
He will also talk you through how to get these all setup in your CI/CD pipeline so that you can get shorter and faster feedback loops.

Today every developer is using LLMs in different forms and shapes. Lots of products have introduced embedded AI capabilities, and in this workshop you’ll learn how to build your own AI application. No experience in building LLMs or machine learning is needed. Instead, we’ll use web technologies such as JavaScript, React and GraphQL which you already know and love.

In this advanced Next.js workshop, we will delve into key concepts and techniques that empower React.js developers to harness the full potential of Next.js. We will explore advanced topics and hands-on practices, equipping you with the skills needed to build high-performance web applications and make informed architectural decisions.
By the end of this workshop, you will be able to:1. Understand the benefits of React Server Components and their role in building interactive, server-rendered React applications.2. Differentiate between Edge and Node.js runtime in Next.js and know when to use each based on your project's requirements.3. Explore advanced Server-Side Rendering (SSR) techniques, including streaming, parallel vs. sequential fetching, and data synchronization.4. Implement caching strategies for enhanced performance and reduced server load in Next.js applications.5. Utilize React Actions to handle complex server mutation.6. Optimize your Next.js applications for SEO, social sharing, and overall performance to improve discoverability and user engagement.

Unleash the power of AI in your documentation with this hands-on workshop. In this interactive session, I'll guide you through the process of creating a dynamic documentation site, supercharged with the intelligence of AI (ChatGPT).
Imagine a world where you don't have to sift through pages of documentation to find that elusive line of code. With this AI-powered solution, you'll get precise answers, succinct summaries, and relevant links for deeper exploration, all at your fingertips.
This workshop isn't just about learning; it's about doing. You'll get your hands dirty with some of the most sought-after technologies in the market today: Next.js 13.4 (app router), Tailwind CSS, shadcn-ui (Radix-ui), OpenAI, LangChain, and MongoDB Vector Search.

You probably know the story. You’ve created a couple of tests, and since you are using Cypress, you’ve done this pretty quickly. Seems like nothing is stopping you, but then – failed test. It wasn’t the app, wasn’t an error, the test was… flaky? Well yes. Test design is important no matter what tool you will use, Cypress included. The good news is that Cypress has a couple of tools behind its belt that can help you out. Join me on my workshop, where I’ll guide you away from the valley of anti-patterns into the fields of evergreen, stable tests. We’ll talk about common mistakes when writing your test as well as debug and unveil underlying problems. All with the goal of avoiding flakiness, and designing stable test.

Get ready to supercharge your web development skills with React Server Components! In this immersive, 3-hour workshop, we'll unlock the full potential of this revolutionary technology and explore how it's transforming the way developers build lightning-fast, efficient web applications.
Join us as we delve into the exciting world of React Server Components, which seamlessly blend server-side rendering with client-side interactivity for unparalleled performance and user experience. You'll gain hands-on experience through practical exercises, real-world examples, and expert guidance on how to harness the power of Server Components in your own projects.
Throughout the workshop, we'll cover essential topics, including:- Understanding the differences between Server and Client Components- Implementing Server Components to optimize data fetching and reduce JavaScript bundle size- Integrating Server and Client Components for a seamless user experience- Strategies for effectively passing data between components and managing state- Tips and best practices for maximizing the performance benefits of React Server Components

React continues to evolve their beta capability, React Server Components, and they're continuing to further develop them in partnership with frameworks like NextJS.In this workshop, attendees will learn what React Server Components are, how to effectively build and use them in NextJS, and focus on one of the major advantages of React/NextJS: reusability through components.We will also cover related beta technologies enabled by the `app` directory, such as nested layouts and server actions (alpha/experimental capability).Join us for this hands-on, 120 minute workshop!Technologies:
