Did you ever work in a monolithic Next.js app? I did and scaling a large React app so that many teams can work simultaneously is not easy. With micro frontends you can break up a frontend monolith into smaller pieces so that each team can build and deploy independently. In this workshop you'll learn how to build large React apps that scale using micro frontends.

Deno 1.9 introduced a new web server API that takes advantage of Hyper, a fast and correct HTTP implementation for Rust. Using this API instead of the std/http implementation increases performance and provides support for HTTP2. In this workshop, learn how to create a web server utilizing Hyper under the hood and boost the performance for your web apps.

Ever more companies are choosing Micro-Frontends. However, they are anything but easy to implement. Fortunately, Module Federation introduced with webpack 5 has initiated a crucial change of direction.
In this interactive workshop, you will learn from Manfred Steyer -- Angular GDE and Trusted Collaborator in the Angular team -- how to plan and implement Micro-Frontend architectures with Angular and the brand new webpack Module Federation. We talk about sharing libraries and advanced concepts like dealing with version mismatches, dynamic Module Federation, and integration into monorepos.
After the individual exercises, you will have a case study you can use as a template for your projects. This workshop helps you evaluate the individual options for your projects.
Prerequisites:You should have some experience with Angular.

Have you wanted to explore AI, but didn't want to learn Python to do it? Tensorflow.js lets you use AI and deep learning in javascript – no python required!
We'll take a look at the different tasks AI can help solve, and how to use Tensorflow.js to solve them. You don't need to know any AI to get started - we'll start with the basics, but we'll still be able to see some neat demos, because Tensorflow.js has a bunch of functionality and pre-built models that you can use on the server or in the browser.
After this workshop, you should be able to set up and run pre-built Tensorflow.js models, or begin to write and train your own models on your own data.

Most businesses have to build custom software and bespoke interfaces to their data in order to power internal processes like user trial extensions, refunds, inventory management, user administration, etc. These applications have unique requirements and often, solving the problem quickly is more important than appearance. Retool makes it easy for js developers to rapidly build React-like apps for internal tools using prebuilt API and database interfaces as well as reusable UI components. In this workshop, we’ll walk through how some of the fastest growing businesses are doing internal tooling and build out some simple apps to explain how Retool works off of your existing JavaScript and ReactJS knowledge to enable rapid tool building.
Prerequisites:A free Retool.com trial accountSome minimal JavaScript and SQL/NoSQL database experience

In this workshop, through hands-on projects we'll learn how to use Observable, a browser-based reactive coding platform, to rapidly build insightful, interactive visualizations in JavaScript. After completing this workshop, you'll have the basic tools & techniques you need to start using dataviz to better understand your code, your projects & your users, and make better data-driven decisions as a developer.

Even if you're a regular expression pro, it's not always easy to know how to apply them in JavaScript. What's the difference between RegExp.prototype.exec and String.prototype.match ? What if I want to replace all punctuation followed multiple spaces with the same punctuation followed a single space? This workshop will explore the various methods and leave you with sample code, a cheat sheet, and the confidence to choose the right method for the job.
Prerequisites:Node 12+Array methods: map and filterKnowledge of regular expression syntax helpful but not required
Workshop level:JS devs who avoid regular expressions because who has time to figure out which method to use? Level: beginner / intermediate.

The workshop extends JavaScript programming language knowledge, overviews general software design patterns. It is focused on Web Components standards and technologies built on top of them, like Lit-HTML and Lit-Element. We also practice writing Web Components both with native JavaScript and using Lit-Element. In the end we overview key tooling to develop an application - open-wc.

InfluxDB is an open source time series database that empowers developers to build IoT, analytics and monitoring software. It is purpose-built to handle the massive volumes and countless sources of time-stamped data produced sensors, applications and infrastructure.
This workshop showcases a fully functional sample application called IoT Center that is built on InfluxDB. This application demonstrates the capabilities of the InfluxDB platform to develop a JavaScript-enabled time-series-based application. It collects, stores and displays a set of values that include temperature, humidity, pressure, CO2 concentration, air quality, as well as provide GPS coordinates from a set of IoT devices. With this data stored in InfluxDB, the application can query this data for display as well as write data back into the database.
This hands-on workshop will show students how to install this open source code to learn how to query and write to InfluxDB using the InfluxDB JavaScript client, and gain familiarity with the Flux lang query language which is designed for querying, analyzing, and acting on time series data. And finally, collect and visualize performance data of the Node JS application.

D3.js is a powerful JavaScript library for building data visualizations, but anyone who has tried to use it quickly finds out that it goes deeper picking your favorite chart type. This workshop is designed to give you a hands-on introduction to the essential concepts and techniques for creating custom data visualizations with d3.js. By the end of this workshop you will have made an interactive and animated visualization on a realistic dataset that you can easily swap out with your own.

A workshop for UI and Angular beginners alike. Let's pull down the Tour of Heroes app (written John Papa and found throughout the Angular docs) and give it a UI upgrade! All you will need is a laptop and your favorite data set (mine, of course, will be ponies.)

Buddy is a CI/CD tool that lowers the entry threshold to DevOps simplifying pipeline configuration to bare minimum, enabling teams to embrace CI/CD with no dedicated engineers. During the presentation, we will show you how to create a fully functional JavaScript pipeline and adapt it to the workflow in your company in a couple of minutes. We are going to put special emphasis on features that help secure code quality, share some tricks that speed up the deployment (trigger conditions, cache, Docker, changeset deployments, parallelization), and show you how to preview deployed websites with no server infrastructure using Sandboxes – a unique feature of Buddy.

Digital commerce has changed, and there is an increasing demand for faster and kite efficient solutions. In this workshop, you'll learn about the evolution of ecommerce and how Jamstack and headless commerce evolves shopping experiences on the web. We will explore the basics of headless commerce building a minimal Jamstack ecommerce product page with static content, HTML5, CSS, and Javascript. Finally, we will integrate Commerce Layer for headless commerce capabilities and deploy our application to Netlify.
