Web Components in Action

Using a library might seem easy at first glance, but how do you choose the right library? How do you upgrade an existing one? And how do you wade through the documentation to find what you want?
In this workshop, we’ll discuss all these finer points while going through a general example of building a code editor using CodeMirror in React. All while sharing some of the nuances our team learned about using this library and some problems we encountered.

This workshop will teach you the basics of writing useful end-to-end tests using Cypress Test Runner.
We will cover writing tests, covering every application feature, structuring tests, intercepting network requests, and setting up the backend data.
Anyone who knows JavaScript programming language and has NPM installed would be able to follow along.

Passwordless authentication may seem complex, but it is simple to add it to any app using the right tool.
We will enhance a full-stack JS application (Node.JS backend + React frontend) to authenticate users with OAuth (social login) and One Time Passwords (email), including:- User authentication - Managing user interactions, returning session / refresh JWTs- Session management and validation - Storing the session for subsequent client requests, validating / refreshing sessions
At the end of the workshop, we will also touch on another approach to code authentication using frontend Descope Flows (drag-and-drop workflows), while keeping only session validation in the backend. With this, we will also show how easy it is to enable biometrics and other passwordless authentication methods.

Prerequisites- IDE for your choice- Node 18 or higher

Does your React app need to efficiently display lots (and lots) of data in a grid? Do your users want to be able to search, sort, filter, and edit data? AG Grid is the best JavaScript grid in the world and is packed with features, highly performant, and extensible. In this workshop, you’ll learn how to get started with AG Grid, how we can enable sorting and filtering of data in the grid, cell rendering, and more. You will walk away from this free 3-hour workshop equipped with the knowledge for implementing AG Grid into your React application.
We all know that rolling our own grid solution is not easy, and let's be honest, is not something that we should be working on. We are focused on building a product and driving forward innovation. In this workshop, you'll see just how easy it is to get started with AG Grid.
Prerequisites: Basic React and JavaScript
Workshop level: Beginner

In this workshop, we will see how to adopt Orama, a powerful full-text search engine written entirely in JavaScript, to make search available wherever JavaScript runs. We will learn when, how, and why deploying it on a serverless function could be a great idea, and when it would be better to keep it directly on the browser. Forget APIs, complex configurations, etc: Orama will make it easy to integrate search on projects of any scale.

“You’ll never believe where objects come from in JavaScript.”
“These 10 languages are worse than JavaScript in asynchronous programming.”
Let’s explore some aspects of JavaScript that you might take for granted in the clickbaitest nodecongress.com workshop.
To attend this workshop you only need to be able to write and run NodeJS code on your computer. Both junior and senior developers are welcome.
Objects are from Mars, functions are from Venus
Let’s deep-dive into the ins and outs of objects and then zoom out to see modules from a different perspective. How many ways are there to create objects? Are they all that useful? When should you consider using them?
If you’re now thinking “who cares?“, then this workshop is probably for you.
Asynchronous JavaScript: the good? parts
Let’s have an honest conversation.
I mean… why, oh why, do we need to bear with all this BS? My guess is that it depends on perspective too. Let’s first assume a hard truth about it: it could be worse… then maybe we can start seeing the not-so-bad-even-great features of JavaScript regarding non-blocking programs.
