Simulating Sand: Building Interactivity With WebAssembly | JSConf EU 2019

“Falling sand games” were a beloved childhood curiosity, but when I set out to write my own in Javascript, performance got in the way of the scale and granularity I wanted. Could WebAssembly be the tool to build the sand simulation of my dreams, or is it still just for blog posts? I’ll share with you the history and beauty of falling sand games, what I learned building mine to leverage the power of modern browsers, and show you how WebAssembly can cooperate productively with the JS ecosystem to enable awesome web experiences.

JavaScript: who, what, where, why and next | JSConf EU 2019

npm has more data than anyone about who JavaScript developers are and what we’re up to. Using registry stats and the results of our 2019 ecosystem survey of over 30,000 developers, I break down the current state of JavaScript and where trends look like they’re headed, so you can make more informed technical choices.

tink: A Next Generation Package Manager | JSConf EU 2019

With nearly 1,000,000 packages, the npm ecosystem is the largest out there, by far – but the ecosystem and its package manager were created in more humble times, for small projects and packages centered around the Node.js ecosystem itself. It’s about time we redefined package management for modern web development, and that redefinition is tink: a package unwinder for JavaScript brought to you by npm itself. With tink, you’ll find unprecedented speeds, deep compatibility with everything from Node.js to bundlers, and a UX workflow optimized for the modern web developer. Come join us for the official unveiling and find out what the future of all package management will look like for years to come.

Web APIs in Node.js Core: Past, Present, and Future | JSConf EU 2019

Web APIs developed and standardized by the browsers have been serving client-side JavaScript applications with a wide selection of features out of the box, while Node.js have been developing another set of APIs that are today the de-facto standards for server-side JavaScript runtimes. There is now a conscious effort to bring the two worlds closer together, in particular by introducing more Web APIs into Node.js core, but it’s not an easy ride - not every Web API, designed for the browsers, makes sense for Node.js. In this talk, we are going to take a look at the story of Web APIs in Node.js core - what Node.js have implemented, what are being discussed, what are blocking more APIs from being implemented, and what we can do to improve the developer experience of the JavaScript ecosystem.

Promises API in Node.js core: where we are and where we’ll get to | JSConf EU 2019

Currently only ‘fs’ and ‘dns’ have an experimental promise api in Node core. People LOL at node.js core modules for still using the callback pattern. I could launch into a bunch of puns here but instead I’ll just say the current status is sad but fixable. Where are we? What do we need to do? How can you help?
