Leveraging LLMs to Build Intuitive AI Experiences With JavaScript
Workshop
Today every developer is using LLMs in different forms and shapes, from ChatGPT to code assistants like GitHub CoPilot. Following this, lots of products have introduced embedded AI capabilities, and in this workshop we will make LLMs understandable for web developers. And we'll get into coding your own AI-driven application. No prior experience in working with LLMs or machine learning is needed. Instead, we'll use web technologies such as JavaScript, React which you already know and love while also learning about some new libraries like OpenAI, Transformers.js

GraphQL for React Developers
Featured Workshop
There are many advantages to using GraphQL as a datasource for frontend development, compared to REST APIs. We developers in example need to write a lot of imperative code to retrieve data to display in our applications and handle state. With GraphQL you cannot only decrease the amount of code needed around data fetching and state-management you'll also get increased flexibility, better performance and most of all an improved developer experience. In this workshop you'll learn how GraphQL can improve your work as a frontend developer and how to handle GraphQL in your frontend React application.

When (Not) To Create A GraphQL Server
Every (frontend) developer is asking for a GraphQL API but often lacks the backend knowledge to create a performant server. There are many different flavors in creating the perfect GraphQL server, ranging from schema-first to code-first or even auto generated solutions. Let me show you the pros and cons of each solution so, after this talk, you'll know which solution would best fit your team.

Building a Serverless GraphQL API For Any Datasource With StepZen
WorkshopFree
Want to get started with building a GraphQL server but have no idea where to begin? Every (frontend) developer asks for a GraphQL API but often lacks the backend knowledge to create a performant one. There are many different flavours in creating the perfect GraphQL server, ranging from schema-first to code-first or even auto-generated solutions.

In this interactive workshop, you will learn about building a serverless GraphQL API using StepZen. With StepZen, you can create a GraphQL for any data source (SQL, NoSQL & REST) and even other GraphQL APIs within minutes. And even handle more complicated use cases such as authentication and deployment. Using little code, you'll get to combine different data sources in one fully performant API that you can use in your applications from day one.

Table of contents:
- What is StepZen?
- Connecting to a data source (SQL, NoSQL & REST)
- Using custom directives
- Handle sequence flows
- Deployment

Killing BFFs with GraphQL and Next.js
Top Content
Frontend applications are getting more and more complicated, often delivering far more than just a UI. With this growing complexity comes a growing need for knowledge from the developers creating it, as they have to deal with matters like state-management, authorization, routing and more. In this talk, I'll show you how to use GraphQL in your Next.js application to create a data layer for your application, that exists between your frontend and your backend. In this data layer, you can handle complex matters to help you to keep your frontend application clean and "stupid".

Let's Talk GraphQL With Your Services
GraphQL is a query language for APIs, but what if your API doesn't support GraphQL? There's a lot of information on how you can use GraphQL to make your APIs more readable or even more content on using GraphQL as a data layer for your existing APIs. This all makes perfect sense, but what if you actually want to know how to transform existing services to GraphQL? In this talk I'll demonstrate how you can use your existing services to create GraphQL schemas using Abstract Syntax Trees and TypeScript.This is not a talk to show how to wrap services with GraphQL, in this talk I'll show data models to use an AST to transform existing services to GraphQL. Also, thinking patterns and best class approaches will be shown.

State Management in React with Context and Hooks
WorkshopFree
A lot has changed in the world of state management in React the last few years. Where Redux used to be the main library for this, the introduction of the React Context and Hook APIs has shaken things up. No longer do you need external libraries to handle both component and global state in your applications. In this workshop you'll learn the different approaches to state management in the post-Redux era of React, all based on Hooks! And as a bonus, we'll explore two upcoming state management libraries in the React ecosystem.
