How many ways do you know to do iteration with JavaScript and Node.js?
While, for loop, for...in, for..of, .map(), .forEach(), streams, iterators, etc! Yes, there are a lot of ways! But did you know that JavaScript has iteration protocols to standardise synchronous and even asynchronous iteration?

In this workshop we will learn about these protocols and discover how to build iterators and iterable objects, both synchronous and asynchronous. We will learn about some common use cases for these protocols, explore generators and async generators (great tools for iteration) and finally discuss some hot tips, common pitfalls, and some (more or less successful) wild ideas!

Workshop: JavaScript iteration protocols

Node-RED is a low-code platform that makes it super simple to build event-driven applications within the browser that are deployed to its Node.js runtime.

The main way the platform can be extended is by creating new nodes in its palette. With close to 4000 nodes already available, there's a lot to choose from. But there's always room for more.

This workshop will walk through the process of taking an existing npm module and wrapping it to use within Node-RED.

Building Node-RED Nodes for fun or profit

A guide to building a GraphQL API server using Fastify and Mercurius. This workshop will guide participants in building a high-performance, scalable, and customizable graphQL server. This covers the backend stack and uses all open-source, community-driven technologies. Starting with the basics and ramping up to advanced GraphQL techniques including error handling, federation, and fragments. After completing the workshop, participants will have an understanding of the required concepts and skills that are required to build a production-grade GraphQL server.

From zero to GraphQL

In this workshop we will make a smart webcam application with pre-trained Machine Learning models that runs on the browser, using the most popular Machine Learning framework for Javascript: TensorFlow.js

Intro to TensorFlow.js

A well-designed Node.js CLI tool can make life better, for you and your users. But what’s the best way to design one that meets user needs, and then how do you pick the libraries to help you build it?

Which library will you use to parse the command-line arguments? And which will you use to ask questions and get responses from your users? How about getting data from an external API? That’s a lot of decisions, and potentially a lot of libraries!

Node.js core is evolving all the time and the libraries you might have relied on before to build CLIs aren’t always needed. Newer APIs such as parseArgs, readline/promises and fetch give us exciting new opportunities for building CLI tools with Node.js.

In this workshop we’ll explore what makes a human friendly CLI and how we can leverage Node.js core to help our users achieve their goals, and live their best command-line lives.

Crafting human friendly CLIs with Node.js core

This workshop provides an introduction to cloud native development with Node.js. The workshop will walk you through building cloud native Node.js applications, incorporating typical components including observability components for logging, metrics, and more. Next, we’ll show you how to deploy your application to cloud environments. The workshop will cover cloud native concepts and technologies, including health checks, metrics, building containers, and deployments to Kubernetes.

Elevating Node.js Applications to the Cloud

Platformatic DB allows you to rapidly develop GraphQL and REST APIs on top of an SQL database (SQLite, PostgreSQL, MySQL and MariaDB). What’s special about it? Platformatic DB allows you to unleash the full potential of Node.js and Fastify whenever you need it - you can customise its behaviour by writing additional features and plugins. Bonus points: it automatically reloads without losing a single request.

In this workshop, we’ll develop a full stack web application using Platformatic DB and Astro - the Movie Quotes app!

Introducing the Platformatic DB

Overwhelmed with security issues in your Node.js applications? Not entirely sure how to write secure code? Join us in this workshop where you’ll learn how to improve security without being a security professional. We’ll use Snyk Code’s VS Code extension to catch and find security issues while you code, automatically fix security issues in your open source libraries, and see first-hand how to weaponize vulnerabilities to exploit working Node.js applications. You will also learn about the multiple ways of using Snyk to secure your projects, from the CLI, to CI/CD pipelines with GitHub Actions, and extend your know from secure code and secure dependencies to that of building secure containers to your Node.js apps on Docker.

Developer Security Essentials with Snyk

In this workshop, we’re going to have fun building a simple dynamic application using a workflow unlike anything you’ve done before with Node. Why? because we’ll use the RedwoodJS full-stack open-source framework. The app will consist of a React frontend and a GraphQL backend, including Prisma and Fastify. You’ll learn how to use Directives to transform data and Services to keep business logic organized and reusable. Redwood also comes with integrated authentication with RBAC (for both API and web), Jest tests (with mocks and scenarios), and Validations — we’re going to put all of them to work in our app.

You may ask, “How is all this possible in a 3-hour workshop?” Well, Redwood includes all these technologies out of the box. We’ll use CLI code generators to quickly scaffold boilerplate so we can get to work on features. Fas

Going Full Stack with RedwoodJS

Learn how to develop apps in JavaScript for the Bangle.js 2 smartwatch, and use Web Bluetooth inside a bookmarklet to allow the watch to control or display information from an existing website, without having to modify it.

Integrate external hardware into your website

Learn how content addressed user-centric protocols like IPFS, DID, and UCAN will change the web, and how to build Node.js applications using them. The web3.storage team will share the latest APIs and walk you through building your own application data model. Start with DID-based self-sovereign auth, a great opportunity to learn about the next wave of digital identity, and write code to upload files as well as JSON objects. They'll discuss IPFS data structures like IPLD trees and graphs, and how they can be used in applications.

UCAN Build Apps with IPFS

Come learn techniques for bidirectional streaming over websockets and distributed state synchronization in a fully serverless environment with Cloud Pong, a fun retro nod to Pong, the 1970s iconic table tennis style arcade game with two paddles and a ball.
The talk walks through a fully serverless JavaScript implementation. The demo uses Cloud Run and Upstash, but attendees can apply the architectural and programming concepts to target other serverless environments that support websockets.

Developing a fully serverless distributed computing app

This workshop provides an introduction into using a node application gateway as a central authentication and authorisation system for a suite of microservices.
Using OAUTH 2.0 and JWT tokens the node application provides a central location to manage user access and prevent redundant and repeated access check across multiple microservices.
