The State of Node Compatibility in Deno

Can Deno run apps and libraries authored for Node.js? What are the tradeoffs? How does it work? What’s next?

Setting up JavaScript projects is no fun. Getting started involves installing and configuring node, tsc, prettier, eslint, a testing framework, a database driver, and more. Why is JavaScript not batteries included? In this talk we'll talk about how Deno fixes this, letting you focus on building stuff. We explore what benefits full tooling integration unlocks, and remember how fun it is to program if your tools help you, rather than requiring your babysitting.

Deno 2.0 is imminent and it's bringing some big changes to the JavaScript runtime. In this talk, we'll introduce the new features including import maps, package.json auto-discovery, and bare specifiers. We'll discuss how these improvements will help address issues like duplicate dependencies and disappearing dependencies. Additionally, we'll delve into the built-in support for deno: specifiers on the deno.land/x registry and its role in providing a recommended path for publishing. Come learn about how these updates will shape the future of the JavaScript ecosystem and improve backwards compatibility with Node applications.

Bun, Deno, and many other JavaScript runtimes have been hyped, but do you know why? Is it that easy to make a runtime from scratch?

I've been researching the secret behind Node.js' power and why there are so many new JavaScript runtimes coming up. Breaking down each key component used on Node.js I've come to interesting conclusions that many people used to say whereas in practice it works a bit differently.

In this talk, attendees will learn the concepts used to create a new JavaScript runtime. They're going to go through an example of how to make a JavaScript runtime by following what's behind the scenes on the Node.js project using C++. They'll learn the relationship between Chrome's V8 and Libuv and what makes one JavaScript runtime better than others.

This talk will cover the following topics:
- What's a JavaScript Engine - V8
- Why Node.js uses Libuv
- How to create a JS Runtime from scratch

This talk will walk you through writing a module in TypeScript that can be consumed by users of Deno, Node, and browsers. I will walk through how to set up formatting, linting, and testing in Deno, and then how to publish your module to deno.land/x and npm. I will also start out with a quick introduction on what Deno is.
