Running tests on Node.js is common practice for app and library developers. But when your library is integrating more deeply with the platform, operating system or JS engine, you need to run tests “on device” increases. The Realm JS team at MongoDB is faced with this challenge, as we’re maintaining a React Native library with native modules. In this talk I’ll share the “mocha-remote” package which we’ve built to help us run tests “on device” while getting reporting and remaining in control from the comfort of our terminals.

You’re curious about what Apache Kafka does and how it works, but between the terminology and explanations that seem to start at a complex level, it's been difficult to embark. This session is different. We'll talk about what Kafka is, what it does and how it works in simple terms with easy to understand and funny examples that you can share later at a dinner table with your family. This session is for curious minds, who might have never worked with distributed streaming systems before, or are beginners to event streaming applications. But let simplicity not deceive you - by the end of the session you’ll be equipped to create your own Apache Kafka event stream!

In a world run by data, we as developers have turned to schemas to help describe and organize that data. But what happens when you have a ton of schemas to keep track of? In this talk you will learn the role of all the different schemas in a GraphQL API.

Join Thomas from the GraphQL Team at Neo4j as he talks about one of the newest features of the Neo4j GraphQL Library: GraphQL Subscriptions. Using this new feature, GraphQL API consumers can listen to data changes in real-time, which happen in Neo4j via the GraphQL Library. Following a high-level overview of the Neo4j GraphQL Library, he will demonstrate the new Subscriptions feature.

In today's world, it's no surprise that "Content is King". It helps in telling a story and helping you reach out to more people. Most of the time, developers aren't the ones managing this content. Hence, modeling content efficiently becomes crucial. Doing it well makes the content delivery process smooth for the team. But how does one go on with modeling content? What are the things that one should take care of? I'll answer such questions in this talk, and share my approach to content modeling as a React developer.

Functional Programming (FP), a paradigm in which programs are made up of pure, stateless functions, is adored by many programmers for how easy it makes it to predict, test, and debug the behavior of the code we write. Although FP has an unfortunate reputation as an ivory-tower domain full of obscure jargon comprehensible only to those with PhDs in category theory, the core concepts are straightforward ideas all of us can understand, and even have fun learning! In this talk, we’ll create generative SVG art as a way to explore fundamental FP concepts such as recursion and function composition, and tackle the practical challenges of FP in the real world, such as dealing with the tricky parts like side effects and randomness which don’t fit into the safe, sterile world of pure functions. By the end of the talk we’ll not only have the key concepts &amp; techniques we need to start writing our own functional programs, we’ll have some pretty functional art to look at too!

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 &amp; 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 &amp; REST) - Using custom directives - Handle sequence flows - Deployment <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

TypeScript makes JavaScript safer adding static type definitions. Static definitions are wonderful; they prevent developers from making trivial mistakes ensuring every assignment and invocation is done correctly. A variable typed as a string cannot be assigned a number, and a function expecting three arguments cannot be called with only two. These definitions only exist at build time though; the code that is eventually executed is just JavaScript. But what about the response from an API request? In this talk Ethan Arrowood, Software Engineer 2 @ Microsoft, he will cover various solutions for safely typing dynamic data in TypeScript applications. This talk features popular technologies such as Fastify, JSON Schema, Node.js, and more! <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
